Signature/sign-pdf

From Safe Stamper API
Jump to: navigation, search

Uploads a PDF document for signing

This operation must use an HTTP multipart/form-data post request.

You can send an HTML text instead using signature/sign.

For each signature, the signer name and email or phone number must be provided.

An email or SMS will be sent to each document signer with an URL they must visit to sign the document. When all signers have added their signature, a signature certificate will be generated and sent to all the document signers, and to the document sender e-mail address if specified.

Document signing process status can be queried using signature/status.

If your API client has a callback URL, it will receive the following callbacks:

  • DOCUMENT_SIGNATURE: When a signer signs the document
  • SIGNATURE_CERTIFICATE: When the document signature certificate is ready

These callbacks receive the same JSON as returned from signature/status.
