The TaxRock Delegate API lets your application read TaxRock data on a TaxRock user’s behalf, after the user grants consent once. It is a standard OAuth 2.0 Authorization Code + PKCE integration.

​
How it works

1

The user connects (once)

You send the user to TaxRock to log in and consent. TaxRock redirects back to your app with an authorization code.
2

Your backend gets tokens

Exchange the code for a long-lived refresh token and a short-lived access token. Store the refresh token securely, per end-user.
3

You call the API

Send the access token as a Bearer credential. When it expires (~1 hour), exchange the refresh token for a new one.
Start with the Quickstart to get from zero to a successful call.

​
Sandbox vs. production

Everything defaults to the sandbox while you build. Two base URLs change between environments. The audience is the same in both.

Your client_id and client_secret are delivered to you per environment. Send us your callback URL so we can register it before the connect flow will work.
