PHP curl call from localhost return UNAUTHENTICATED_API_CALL

[Community_Team]

Thanks @manoj, I know for when you use localhost for certain complete, cancel and error urls in the parameters, you will have to use ngrok.

However this may be an issue due to the signature request.

From the error response, this may be due to a couple things:

1. All spaces and other whitespace outside of strings must be removed.
2. Numbers should be sent in strings, not as integers/numbers.

Here are some resources that may help:

I would also take a look around your body and and how it may not be parsed correctly.
