Hi @expertoswp
If you could provide some sample code, that would be a great help to try and replicate this issue.
As I mentioned in another thread, the errors are returned as text with a description of what went wrong. They wouldn’t usually come in the format you’ve pasted in the first message, which suggests it may be an error on “make.com”.
If you log any API calls for debugging purposes that have caused that error, you’re welcome to send both the request and the response to us privately to investigate further.
The reason I asked about coding language above (which may be the same reason other users also asked), is that I am aware of an unofficial PHP library which may help with the development.
