Authentication to the API is performed via an API key in the X-API-Key header.

Your API keys carry many privileges, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.

You can get a free test API key to try out SignatureAPI and set up your workflow. Here’s how:

1

Sign Up

Sign up for a free account on SignatureAPI.

2

Get your API key

Get your test API key from the SignatureAPI Dashboard.

Test API keys let you create test envelopes, great for trying out your workflows. Envelopes in test mode:

  • They don’t send emails to recipients, but you can see them in the Email area of your dashboard.
  • They are not legally-binding, so no legal obligations arise during testing.
  • They are free.
