API-Dokumentation

Bauen Sie das Unterschreiben mit dem Personalausweis in Ihr eigenes System ein. Dokument hochladen, Signaturanfrage erstellen und per Webhook benachrichtigt werden, sobald unterschrieben wurde.

Erste Schritte

  1. Erstellen Sie einen Testschlüssel unter Konto → Entwickler. Testschlüssel (sk_test_…) unterschreiben gegen die Testumgebung: echter Ablauf, aber ohne Zahlung, ohne Kontingent und ohne echtes Geld.
  2. Laden Sie das PDF mit POST /v1/documents hoch.
  3. Erstellen Sie die Unterschrift mit POST /v1/signature_requests.
  4. Registrieren Sie einen Webhook-Endpunkt, dann melden wir uns, sobald das Dokument vollständig unterschrieben ist.
  5. Wechseln Sie auf einen Live-Schlüssel (sk_live_…), sobald alles läuft.

Authentifizierung

Senden Sie den Schlüssel als Bearer-Token. Jeder Schlüssel hat einen Satz Berechtigungen (Scopes) — er erreicht keine Endpunkte, für die er keine Freigabe hat, und ein Schlüssel kann niemals einen neuen Schlüssel erstellen.

Die Berechtigungen wählen Sie beim Anlegen des Schlüssels. Bei jedem Endpunkt unten steht, welche er erfordert — fehlt sie, erhalten Sie 403 insufficient_scope, und WWW-Authenticate nennt die nötige Berechtigung.

Was vom Kontingent abgezogen wird und was beim Stornieren und Ablaufen passiert: Preise und Zählung der Unterschriften →

HTTP

Authorization: Bearer sk_live_...

Idempotenz

Senden Sie bei jedem POST einen Idempotency-Key mit. Bricht die Verbindung mitten im Aufruf ab, können Sie mit demselben Schlüssel gefahrlos erneut senden: Sie erhalten die ursprüngliche Antwort statt einer zweiten Signaturanfrage. Derselbe Schlüssel mit anderem Inhalt liefert 422 — das ist ein Fehler auf Ihrer Seite, und den verbergen wir nicht.

Testumgebung

Schlüssel mit dem Präfix sk_test_ laufen gegen die Testumgebung. Alles verhält sich wie in der Produktion, aber die Signierung läuft über Criiptos Testumgebung mit einer Testidentität, und die Signatur ist nicht rechtsverbindlich. Testaufträge kosten nichts und belasten Ihr Kontingent nicht.

Die Testumgebung versendet echte E-Mails und echte SMS an die von Ihnen angegebenen Empfänger. E-Mail-Betreffs beginnen mit «[TEST]», SMS ebenfalls — so hält niemand eine Testnachricht für echt. Testdokumente erhalten nie Erinnerungen.

Da Testnachrichten für Sie kostenlos sind und von unserer Domain und unserer Nummer ausgehen, ist das Volumen pro Konto begrenzt: 50 E-Mails und 10 SMS je rollierende 24 Stunden. Ist das Budget aufgebraucht, schlägt nichts fehl — der Auftrag wird angelegt und signUrl funktioniert wie gewohnt. Nur die Nachricht geht nicht raus, und die Antwort weist im testMode-Block darauf hin.

Documents

POST/api/v1/documents

Upload the PDF(s) to be signed

Step one of every integration. Upload as multipart/form-data; the id you get back is what POST /signature_requests takes. An sk_test_ key produces a test-mode document, and a test document can only ever be signed by a test key.

Erfordert Berechtigung: documents:write

Header

  • Idempotency-Keystring

    Makes the write retry-safe: a retry with the same key replays the original response instead of creating a second signature request. Same key + a different body is a 422.

Anfrage multipart/form-data

  • ownerEmailstringerforderlich

    Where the receipt and the signed PDF are sent. Must contain an @.

    post@firma.no

  • filesbinaryerforderlich

    The document. Repeat the field to upload several — they are merged in the order sent. PDF and Word (.docx) are accepted; a Word file is converted to PDF on upload. Older .doc, .odt and .rtf must be saved as .docx or PDF first. Per-file and per-request limits apply (25 MB per file, 10 files, by default).

  • templateSlugstring

    Optional. The /maler template the document was filled from — echoed on the completion surfaces.

Signature requests

POST/api/v1/signature_requests

Create a signature request

Sends the document to each signer for BankID/eID signing and returns the request in its initial state. Each signer is emailed (or texted) their own signing link. Pass useSubscription: true to draw the signature from the account's quota: the invitations go out immediately and no money moves. Without it (and without paymentMethod) the request is created in pending_payment and the response carries a payment_url — send the sender there, and the invitations go out once they've paid. To pay without a payment page, name paymentMethod: balance, card, or auto for whatever the account pays with. **How the quota is drawn:** one signature per signer, taken when the request is created — not when it completes. The number of files doesn't matter. Cancel a request before anyone signs and they all come back (POST /signature_requests/{id}/cancel); an expired request keeps them. A document whose request was cancelled can be sent again with the same documentId. The response carries each signer's own sign_url and sign_url_direct. Combine them with notifySigners: false to run the whole notification side yourself — see those fields.

Header

Anfrage application/json

  • documentIduuiderforderlich

    From POST /documents. Must belong to the same account as the key.

  • signersobject[]erforderlich

    At least one signer, invited in the order given. There is no upper limit.

  • namestring

    Shown in the invitation. The legal identity comes from the eID, not from this.

    Ola Nordmann

  • emailstring

    ola@example.no

  • phonestring

    E.164 or a local number, e.g. +47 912 34 567. Only honoured while SMS delivery is enabled for the account.

  • useSubscriptionboolean

    Draw the signature from the account's quota instead of a payment. 409 quota_exceeded when the quota is spent. Equivalent to paymentMethod: "subscription".

    true

  • paymentMethodstring (5 values)

    How to pay. Omitted: the request waits in pending_payment with a payment_url, unless useSubscription: true — the same as before this field existed, so an existing integration never starts spending quota or money without asking for it. - subscription — the quota. Same as useSubscription: true. - balance — the prepaid balance, at the pay-per-use price (signers × unit price, plus the SMS add-on when smsDelivery is on). The invitations go out immediately; 402 insufficient_balance when it doesn't cover the request. Check it with GET /balance. - card — the card saved under /konto/betaling, charged immediately at the pay-per-use price. A declined card refuses the request (402 payment_method_declined, or payment_method_action_required when the bank wants the customer present — the card then has to be saved again). Nothing is created for a declined card. - checkout — always a payment_url, even on an account with a subscription. - auto — whatever this account pays with: its subscription quota when it has one (never falling back to money when the quota runs out), else the way it chose under /konto/betaling. Never a checkout link: 409 no_payment_method when there is nothing to charge. Use it from a server that has no human to send to a payment page.

  • mode"merged" | "separate"

    Sign the uploads as one merged PDF (default) or as separate documents.

  • deadlineDaysinteger

    Days until the request expires. Defaults to the account's configured deadline.

    14

  • passwordstring

    Shared secret a signer must enter before the document is shown.

  • includePasswordInEmailboolean

    Whether that password is included in the invitation email. Defaults to true.

  • smsDeliveryboolean

    Also text the signing link. Free on subscription-covered requests, a surcharge on pay-per-use. Defaults to **true** on a subscription (the quota includes it) and false otherwise — so pass false explicitly if you never want us to text your signers. A phone-only signer is texted regardless, since it is their only channel; to silence that too, use notifySigners: false.

  • notifySignersboolean

    Whether **we** message the signers at all: the invitation, its SMS, the reminder sequence and the completion email. Defaults to true. Set false when your own product owns the conversation — otherwise your customer receives two invitations, from two senders, for one signature. You then have to deliver signers[].sign_url (or sign_url_direct) yourself: with this off, that link is the only way anyone reaches the signing page.

  • notifySenderboolean

    Whether we email the sender (ownerEmail) the receipt, the progress updates and the completed document. Defaults to true. The status and payment URLs are in this response and the signed PDF is downloadable over the API, so an integration loses nothing by turning it off.

  • sealFooterboolean

    Stamp a seal band across the bottom of **every page**: the parties who sign it on the left, "Forseglet via esigner" on the right — the shape Posten's signing product uses. Off by default. The band goes into the file before anyone has signed, so it names the parties rather than announcing a completed signature. **It locks the signer roster.** The band has to go into the PDF before the eID hand-off, because a PAdES signature covers the whole file and nothing can be added afterwards; a signer added later would be missing from a roster already sealed inside the signed document. So POST /orders/{id}/signers/* returns 409 seal_footer_locked for the life of the request. Decide the signer list up front. The band names each signer as Name (email) — or just the email or phone number when you gave no name — exactly what you supplied here. It carries no signing dates and no eID-verified legal names: those are only known after signing, and they are on the provider's attest page inside the same file. Only the copy sent for signing is stamped; the source PDF you uploaded is left untouched.

Antwort 201SignatureRequest

The created signature request

  • iduuiderforderlich

    The signature request id — pass it to GET /signature_requests/{id}.

  • object"signature_request"erforderlich
  • statusstringerforderlich

    draft | pending_payment | in_progress | completed | expired | cancelled | signing_failed. in_progress means the signers have been invited; cancelled means it was stopped before anyone signed (see POST /signature_requests/{id}/cancel); signing_failed means the eID provider rejected the handoff and the request can be retried.

  • documentobjecterforderlich

    The document being signed.

    2026-07-13T10:24:00.000Z

  • sign_urlstringerforderlich| null

    This signer's private signing page — the document, the deadline, and the button that starts BankID/MitID. It is the same URL the invitation email carries, so it is safe to send even when we also mailed it; with notifySigners: false it is the ONLY copy that exists and you must deliver it yourself. **Treat it as a credential**: the token in the path is what authorises the signature, so anyone holding the link can sign as that person. Send it to the signer, never anywhere public. null until the request has been handed to the eID provider (i.e. while it is still pending_payment), and on requests created before this field existed.

    https://esigner.no/sign/9f1c0f4e3d2b4a719f3a1c0…

  • sign_url_directstringerforderlich| null

    Same signer, one step shorter: a redirect that takes them straight into BankID/MitID with no esigner page in between. For a flow whose own UI already showed the document and collected the approval click. Falls back to sign_url by redirecting there whenever it cannot skip — the request is password-protected, expired, cancelled, or the eID hand-off has not finished — so it is always safe to link. Note the signer then never sees the document on OUR surface: in the hosted eID flow the provider still presents it before signing, so use this when your own product has already put the document in front of them.

  • payment_urlstringerforderlich| null

    Where to send the sender to pay, while status is pending_payment. null on a subscription-covered request, and once the payment has gone through. Safe to hand to a human at any time: it resumes the checkout if the request is still unpaid and lands on the status page if it isn't.

    https://esigner.no/api/orders/3f7c1e42-9b0a-4d7…

  • signed_documents_urlstringerforderlich| null

    Where to list the signed PDFs, once status is completed. null before that. Requires the same API key — unlike the links in our completion email, this is not a public URL.

    https://esigner.no/api/v1/signature_requests/3f…

  • download_expires_atstringerforderlich| null

    ISO 8601. When the PUBLIC download links (the ones in the completion email and on the status page) stop working. The API download does not expire on it — your account keeps its archive — but treat it as the deadline for fetching and storing your own copy.

POST/api/v1/signature_requests/{id}/cancel

Cancel a signature request

Stops a request that nobody has signed yet. The signing links stop working and the request ends in cancelled. - **Subscription:** every signature it drew goes back to the quota — including signers added later. - **Pay-per-use:** the payment is returned (refunded if captured, released if only authorised). - **Test mode:** nothing was spent, so nothing comes back. Once anyone has signed, it can no longer be cancelled (409 already_signed). A request that has **expired** cannot be cancelled, and the signatures it drew are **not** returned — cancel requests you know won't be signed rather than letting them lapse. **Correcting a mistake:** cancel, then create a new signature request. Pass the same documentId to reuse the upload, or upload the corrected file. It is counted once. Idempotent: cancelling a request that is already cancelled returns 200 with already_cancelled: true and returns nothing a second time.

Erfordert Berechtigung: orders:write

Pfadparameter

  • iduuiderforderlich

Header

  • Idempotency-Keystring

    Makes the write retry-safe: a retry with the same key replays the original response instead of creating a second signature request. Same key + a different body is a 422.

Anfrage application/json

  • reasonstring

    Optional. Why it was cancelled — kept in the request's audit trail, never shown to the signers.

    Wrong signer email — resending

Antwort 200object

The request is cancelled

  • signature_requestSignatureRequesterforderlich
  • iduuiderforderlich

    The signature request id — pass it to GET /signature_requests/{id}.

  • object"signature_request"erforderlich
  • statusstringerforderlich

    draft | pending_payment | in_progress | completed | expired | cancelled | signing_failed. in_progress means the signers have been invited; cancelled means it was stopped before anyone signed (see POST /signature_requests/{id}/cancel); signing_failed means the eID provider rejected the handoff and the request can be retried.

  • signed_atstringerforderlich| null

    ISO 8601, null until this signer has signed.

    2026-07-13T10:24:00.000Z

  • sign_urlstringerforderlich| null

    This signer's private signing page — the document, the deadline, and the button that starts BankID/MitID. It is the same URL the invitation email carries, so it is safe to send even when we also mailed it; with notifySigners: false it is the ONLY copy that exists and you must deliver it yourself. **Treat it as a credential**: the token in the path is what authorises the signature, so anyone holding the link can sign as that person. Send it to the signer, never anywhere public. null until the request has been handed to the eID provider (i.e. while it is still pending_payment), and on requests created before this field existed.

    https://esigner.no/sign/9f1c0f4e3d2b4a719f3a1c0…

  • sign_url_directstringerforderlich| null

    Same signer, one step shorter: a redirect that takes them straight into BankID/MitID with no esigner page in between. For a flow whose own UI already showed the document and collected the approval click. Falls back to sign_url by redirecting there whenever it cannot skip — the request is password-protected, expired, cancelled, or the eID hand-off has not finished — so it is always safe to link. Note the signer then never sees the document on OUR surface: in the hosted eID flow the provider still presents it before signing, so use this when your own product has already put the document in front of them.

  • payment_urlstringerforderlich| null

    Where to send the sender to pay, while status is pending_payment. null on a subscription-covered request, and once the payment has gone through. Safe to hand to a human at any time: it resumes the checkout if the request is still unpaid and lands on the status page if it isn't.

    https://esigner.no/api/orders/3f7c1e42-9b0a-4d7…

  • signed_documents_urlstringerforderlich| null

    Where to list the signed PDFs, once status is completed. null before that. Requires the same API key — unlike the links in our completion email, this is not a public URL.

    https://esigner.no/api/v1/signature_requests/3f…

  • download_expires_atstringerforderlich| null

    ISO 8601. When the PUBLIC download links (the ones in the completion email and on the status page) stop working. The API download does not expire on it — your account keeps its archive — but treat it as the deadline for fetching and storing your own copy.

    2026-08-13T10:24:00.000Z

  • already_cancelledbooleanerforderlich

    True when an earlier call had already cancelled it. Nothing was returned by this call.

  • released_signaturesintegererforderlich

    Signatures returned to the subscription's quota by this call.

    Pay-per-use amount no longer charged by this call, in minor units (øre), VAT included.

Fehler

Alle Fehler antworten mit JSON und einem stabilen Code im Feld error. Die Codes unten sind die, denen Sie begegnen können — bauen Sie Ihre Logik darauf auf, nicht auf dem Text.

StatusCodeBedeutet
400validationThe request body failed schema validation. issues carries the field-level detail.
401unauthorizedMissing, malformed or revoked API key.
403insufficient_scopeThe key is valid but lacks the scope the endpoint declares. WWW-Authenticate names what was needed.
403cross_owner_documentThe documentId belongs to a different account than the key.
404not_foundNo such resource — or it belongs to another account. Deliberately indistinguishable.
409quota_exceededThe subscription has too few signatures left for this request. remaining says how many there are. Every plan has a hard limit — Team's is a per-seat monthly pool shared by the whole company.
400payment_method_conflictpaymentMethod contradicts useSubscription or a free-signing link. Send one or the other.
409no_payment_methodpaymentMethod: "auto" but the account has no subscription or payment method to charge.
402insufficient_balanceThe prepaid balance doesn't cover the request. balanceOre and requiredOre say by how much. Nothing was created.
402payment_method_declinedThe saved card was declined. declineCode carries the bank's reason. Nothing was created.
402payment_method_action_requiredThe bank requires the cardholder to be present. Save the card again under /konto/betaling.
503payment_unconfirmedThe card charge's outcome could not be confirmed. orderId is returned — read it before retrying, so a held payment isn't doubled.
409payment_method_unavailableThe named paymentMethod is not offered on this deployment.
409already_signedCancel was refused: at least one signer has already signed.
409not_cancellableCancel was refused: the request is no longer open (completed, expired, failed, or locked).
502payment_reversal_failedCancel could not return the pay-per-use payment, so the request was left open. Retry.
409no_subscriptionuseSubscription: true but the account has no active subscription.
409topup_in_progressAn automatic top-up is already running. Retry shortly.
409topup_cooldownA renewal failed recently; automatic top-up is on a 24h cool-down.
409not_completedThe signed PDF was requested before every signer had signed. detail names the current status.
409seal_footer_lockedSigners cannot be added to a request created with sealFooter: true — the roster is inside the signed file.
409signer_roster_fullThe request has room for no more signers: someone has already signed, and the signing provider sizes the signature pages before the first signature. Create a new request for the extra signers.
410goneThe files behind this signature request have been deleted.
410revokedAn administrator has locked this document.
409idempotency_key_in_progressThe first request with this Idempotency-Key hasn't finished. Retry.
413—A single uploaded file exceeded the size limit.
422idempotency_key_reusedThe same Idempotency-Key was used with a different request body. That's a caller bug, so we surface it.
429too_many_requestsRate limited. Retry-After says how long to wait.
502signing_failedThe eID provider rejected the handoff. The document lands in signing_failed and can be retried.
503—Maintenance. New uploads and signature requests are paused; existing ones keep running.

Wir senden Ereignisse per POST an Ihre Adresse und signieren jede Zustellung mit Esigner-Signature: t=<unix>,v1=<hmac>. Der HMAC bildet <t>.<roher Body> ab, damit eine abgefangene Nachricht nicht mit anderem Zeitstempel wiederholt werden kann. Prüfen Sie immer, bevor Sie dem Inhalt vertrauen.

Schlägt eine Zustellung fehl, versuchen wir es in wachsenden Abständen erneut (1 Min. → 6 Std.). Bleibt der Endpunkt längere Zeit stumm, deaktivieren wir ihn und melden uns per E-Mail — die Ereignisse gehen nicht verloren und können erneut gesendet werden.
