Overview

To authenticate with Stripe App Sandbox, you need:

This guide will walk you through finding your App Domain within Stripe.

​

  • You must have created and uploaded a Stripe App.

​
Instructions:

​
Step 1: Finding Your App Domain

After creating your Stripe app and setting up OAuth:
  1. Go to your app’s External test tab in the Stripe Dashboard.
  2. Under Test OAuth, find the Live mode link or Test mode link (e.g., https://marketplace.stripe.com/oauth/v2/ch_1234abcd?client_id=ca_1234XYZ&…)
  3. Your App Domain is the value immediately after /v2/ — in this case, it’s:
ch_1234abcd
This is the unique identifier Stripe assigns to your app instance.

​
Step 2: Enter credentials in the Connect UI

Once you have the App Domain:
  1. Open the form where you need to authenticate with Stripe App Sandbox.
  2. Enter your App Domain in the designated field.
  3. Submit the form, and you should be successfully authenticated.
You are now connected to Stripe App Sandbox.
