Can anyone see what I’m doing wrong here?

I’m trying to use the Bubble API Connector to make a call to [PDF.co](http://PDF.co) PDF-to-Text converter that would generate a text version of PDFs that my users upload to Bubble. I have followed the format that appears in the [Bubble API Connector tutorial](https://manual.bubble.io/help-guides/integrations/api/the-api-connector), the [PDF.co](http://PDF.co) [instruction video](https://www.youtube.com/watch?v=EkavUFpz0Gc), and the [PDF.co](http://PDF.co) documentation on the [Bubble.io](http://Bubble.io) API Connector. The resulting form looks like this:

However, with that, and several permutations of that, attempted both at [Bubble.io](http://Bubble.io) and in tests at [Postman.com](http://Postman.com), I’ve received the same 400 error as follows:

If anyone can spot what I’m doing wrong and how to get it right, I’d greatly appreciate it.

Thanks so much!

It seems the link is not accessible? I can’t see the value of the url but is it accessible? did you try a generic google drive doc as an alt? try quotes around the url value?

Thanks! That _is_ weird.

Are you referring to the link to the api ([https://api.pdf.co/v1/pdf/convert/to/text](https://api.pdf.co/v1/pdf/convert/to/text)) or the sample link to my Bubble data for translation ([//86a6365ce8adc37af942ae5347e7f843.cdn.bubble.io/f1701033482318x372329192966045250/KC-000997\_Onix\_2022Workspace\_ITDM\_Healthcare\_eBook\_r5a.pdf](https://86a6365ce8adc37af942ae5347e7f843.cdn.bubble.io/f1701033482318x372329192966045250/KC-000997_Onix_2022Workspace_ITDM_Healthcare_eBook_r5a.pdf))? That’s a file location stored in my app’s Bubble database.

For the call initiation doesn’t the URL have to be the same location (but not the same field) as what I will eventually connect to the API?
