We are getting the authentication error while using api. We have followed your instructions mentioned in api doc. So please share if you have any php example form creating contact.
Hello @ansar
What’s the exact error you are receiving?
There was a general PHP example posted some time ago using the XML endpoint that may help:
Please send the json format example also in php.
What maybe better is if you could share an example of the code you’re using and the response you’ve received? I’m more than happy to try and help with this 
(Remember to remove any sensitive data)
We got the problem by checking the above xml code and resolved.
