Your blocks look correct and should work as long as the API server is generating a response. What is the value of the green `error` block when you preview the project?

You can also try (temporarily) replacing the green `response` block with a text block and pasting in the contents of the txt file you posted. That should also work as a test.

I couldn’t preview the demo I made because of [this problem](https://community.thunkable.com/t/cant-edit-or-preview-projects/1710542).
