Rabo Identity Services - Sign API

The Sign API is an offering of Rabo Identity Services to sign documents with various signing methods. You can define and integrate the entire signing flow into your own business and company branding.

We support various endpoints and flexibility to support a large number of business requirements.

Each signing flow consists of the below mandatory steps:

  1. Uploading the document(s)
  2. Creating the signing order
  3. Downloading the signed document(s)

Continuing the flow, all the characteristics of a specific order should be defined, example:

  • Number of documents to be signed.
  • Number of signatories required to sign specific documents.
  • Dependencies between signatories.
  • Notifications to invite signatories and/or inform your own backend application on status changes.
  • Generation process of signed documents. 
  • Signing methods allowed to be used by the signatories.

More information on the possibilities on the API can be found in the API specifications.
