Your software through the API

Use Webhooks by Zapier or the Make HTTP module with the existing Envelopify API. There is no dedicated Envelopify app in their catalogue yet.

  1. 1.Choose an event in your software, such as a new invoice.
  2. 2.Create a POST to /api/v1/letters. Use your API key as a Bearer token, Content-Type application/json and a unique Idempotency-Key for each letter.
  3. 3.Map the address and exactly one source: pdf_url, pdf_base64 or a template. Start with a test key and check the response for the letter id and status.
