Test mode

Test mode runs the same API with the same validation, so a payload that works in test mode works live. The differences:

Test mode Live
Emails to signers Never sent Sent
Billing Never billed $1 per envelope sent
PDFs Watermarked “test” on every page Clean
Webhooks Fire, marked test_mode: true Fire
Rate limit 60 requests a minute per test key 600 requests a minute per live key (its test-mode requests count here too)
  • Every request made with an sk_test_ key.
  • A request made with an sk_live_ key that sends Sign-Test-Mode: true. Any other value is ignored.

GET /ping and GET /me tell you which mode you are in with test_mode.

An envelope created in test mode carries test_mode: true for its whole life; it cannot be switched to live, and the database itself refuses to bill it. Test and live data share your account; the request log can be filtered by mode (GET /requests?mode=test).

Some of the table above describes parts that are still arriving (sending, watermarked PDFs, webhooks); see Coming next. What is true today: test requests are never billed and never email anyone.
