Hi,

Can you show us the blocks that you are using? Without that, it will hard form anyone to assist you.

Hi,

What I usually do is to run my API requests in [Postman](https://www.postman.com/) first to make sure that the Headers, Body, Query parameters, etc. are correct. Once I get back an expected response from the API, I then transfer it to Thunkable.

That way you are not trying to figure out if the error lies with Thunkable or the API query.
