Hi,

I have an API call that I am making to Mindee and have tested it in Postman, however when I transfer the information into Thunkable, I cannot get it to work.

Hi, I’d like to suggest a few things -

- As per Mindee API Docs, your authentication token needs to precede with "Token ". So if your token is `abc`, you’ll pass the string “Token abc” to the auth. header. So, join a string block with "Token " written in it.
- You don’t need separate header blocks for multiple headers - click the ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/5/d5ad512478f782c80e959849cf9f5ef2c98c2451.png) icon and add a block below the `Content-Type` header for `Authorization` header.
- Add a 0.001 sec. wait block before making the call, just to smoothen the process.

Let me know if this works. Cheers, Kartik
