Laravel HTTPS API call not working properly

I have an existing admin dashboard built using Laravel 8. In this dashboard, I am calling 2 APIs (one after another) to retrieve data from an external software service and display it on the app. The 1st API call works, but the 2nd API does not work due to a 401 error. Both APIs work in Postman, but not in my Laravel app. I think this issue is related to the authentication token refreshing. This is a very small project just to check the API calls configurations.
