Wildcard support is requested of us fairly frequently and we plan to implement a more long term solution. In the meantime, if your application lives in a GitHub repository connected to Vercel, this topic describes how to add wildcard callback URLs via the Kinde API.

The following is an example of how to use a GitHub workflow to trigger an action every time there is a successful deployment to Vercel.

Step 1: Add a machine to machine application for API access

Since we will be using the Kinde Management API, you’ll need to create a machine to machine application and then activate the connection to the Kinde API.

Then, save the following application details:

1. In Kinde, go to the application and select View details.
2. Scroll to the App keys section and copy the Domain, Client ID, and Client Secret to a text file or somewhere you can access it again.

Step 2: Get the NextJS application ID

1. In the Kinde, select Settings > Applications.
2. Locate your NextJS application and click View details.
3. Copy the application ID from the Client ID field**.**

Step 3: Add secrets to your GitHub repository

1. In your GitHub repository, select Settings.
2. On the left panel, under Security, expand the Secrets and variables list and then select Actions.
3. Select New repository secret on the right.
4. Enter the values that you copied in the steps above. Name these accordingly:
   • BUSINESS_DOMAIN - The Domain found in your machine to machine application.
   • M2M_CLIENT_ID - The Client ID found in your machine to machine application.
   • M2M_CLIENT_SECRET - The Client Secret found in your machine to machine application.
   • APP_ID - The application ID.

Step 4: Add the workflow to your repository

1. In the root of your source code, create a folder called .github.
