Do you have a Console Log for API?

Do you have a Console Log for API?

I'm testing the API and I have some troubles updating template and documents, I'm wondering if there is a way to check the error log so I can see what am I doing wrong?

Or is you can Help me, the company needs to use a template as base to create documents for signin and send to different recipients. so when I try to update the template to change the recipients the response is successfully but the changes are not do it.

Also when I create a new document from template and I put new recipients it does not create or add the new recipients.

What can I do to make this works?
