Facing issues in upload workflow of this plugin.
Can you specify changes on particular areas?
Is it working in your test version but not live?
Also, reset your API key since you just exposed it in the screenshot for everyone to see. 
Checking it on live itself, api key is changed thanks!
earlier tried with live link thats also not working
I will have to go back and look at my setup to see how I have it working.
would be very helpful if you could do that.
What does your upload_pdf workflow look like at the top level?
What about the upload_pdf workflow?
Ok. Well the only thing I see is that the url should be dynamic depending on if you are in the live or the test version. But let me check my setup to see if there is anything else that is needed that might be different.
I couldn’t find my original setup but I found the original post that helped me. Check it out: PDF Conjurer Backend Workflow Retrieve File in Same Workflow - #2 by vini_brito
