How to fix {"errors":["Failed to verify vendor JWT"]

This error can be attributed to three main causes:

1. Incorrect API Gateway Usage: ensure you're utilizing the appropriate API gateway based on your Frontegg account's location:

   • For EU accounts, call api.frontegg.com
   • For US accounts, call api.us.frontegg.com
   • For AU accounts, call api.au.frontegg.com
     
     

2. Vendor Token values: To guarantee the accuracy of your vendor token, call the Vendor authentication API endpoint and pass your Client ID and API Key from Frontegg Portal ➜ [ENVIRONMENT] ➜ Env Settings page

3. Context Mismatch: Verify that you're not calling app-xxx.frontegg.com (user context) instead of api.frontegg.com (vendor context)
