I’m running this API on my private server. Using this link:

[http://209.50.62.89/api.php?name=pen](http://209.50.62.89/api.php?name=pen)

gives me this result:

{“status”:200,“status\_message”:“Product Found”,“data”:10}  
“10” is the correct data for “pen”.

Trying these blocks crashes my app.

Any idea what I’m doing wrong?

Hey @mrtwocanes,

Just tested this on my end on iOS Live Companion. Seeing no issues whatsoever.

 ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/d/f/df5359e95b32370b84e90acec34edf4867965c61.png)

## However

When testing this on Web App it crashes. Are you referring to Web Apps specifically? If not, what device are you using?

Thanks

“eoinparkinson”, thank-you for your reply.

I typically test on a Samsung S6 and a Samsung S9 running the Thunkable Live App. I just tried to test with “Live Test” and then with “Preview as a responsive web app” from the Live Test popup. They both went white and have not changed, so I assume that each crashed. Web App immediately produces a white screen, so no joy there either.

The screen in question works just fine, no crashes UNTIL I put the Web\_API1 “Get” block into place.

I don’t have an iOS device, so I can’t test it on that platform.

Well, I fixed it. I’m just not sure how. I created a new project and recreated the code and it started working. I copied the new blocks to my existing project and Bob’s yer uncle, it was working.

Knowing the code worked for you, helped me to focus. 😂

Thanks for your help!!

@mrtwocanes you seem to have 2 variables with similar names.

There’s `app apiUrl` and `app ApiUrl` which are (were!) two different variables, this is why you weren’t getting the expected result.
