Scope: this guide only covers the exchanges between Tomorro and the integration (the middleware built by the customer). What the integration does with the third-party signature tool (Yousign, Universign, Adobe Sign, LuxTrust, Oodrive…) is out of scope and entirely on the customer’s side. TL;DR Five flows, all between Tomorro and your middleware:
  • Flow 1: Signature is requested. A user sends for signature in Tomorro. Tomorro fires signature.requested, you fetch the document, fields and signatories, then run the signature in your own tool. Tomorro sends nothing to the signatories at any point: your tool owns the whole signer experience, so no double notification.
  • Flow 2: Signature is completed. Once everyone has signed in your tool, you push the signed PDF back. Tomorro moves the contract to signed and runs its post-signature automations.
  • Flow 3: Signature canceled in Tomorro. A user cancels from Tomorro, Tomorro fires signature.canceled, you kill the envelope on your side. Nothing to call back.
  • Flow 4: Signature canceled in your tool. Refused, expired or canceled there: you call cancel-signatures and the contract goes back to draft or negotiating.
  • Flow 5: Attachments (optional). Push the signature certificate, or any supporting document produced by your tool (PDF, Word, Excel…), onto the contract, one file per call.
