Common use cases

Build your integration free

Develop and verify your entire flow end to end before paying for anything.

Automated testing and CI

Run your test suite against real API responses without spending quota.

Demo and staging environments

Keep non-production environments on test mode so demos are never billed.

Key benefits

Free and unlimited on every plan

No cap on test requests, no time limit, and nothing billed, on every plan including Free.

No sandbox account to request

Every account includes test mode. Your development API key plus test mode act as the sandbox: no separate signup, no approval wait.

Real API, clearly marked output

Test requests run through the same API as live ones. Documents get a watermark and red signatures so they are never mistaken for live output.

Frequently asked

Is Anvil test mode free?

Yes. Test mode is free and unlimited on every plan, including the Free plan. Test requests are never billed and never count against your plan quotas.

Set the isTest variable to true when creating e-sign packets or Workflow submissions, or use your development API key: requests made with it run in test mode automatically. PDF fill and generation requests made with the development key are free and watermarked.

No. Every Anvil account includes test mode. Your development API key plus test mode together act as the sandbox environment, with no separate account to request.

Documents filled and signed in test mode contain a watermark and red signatures, and test e-sign packets and Workflow submissions are marked as test in the Anvil UI. Everything else behaves like a live request.

There is no cap on the number of test requests and no time limit. Standard API rate limits still apply, and development key requests are more aggressively rate-limited than live ones.
