I have gone through all the steps to authenticate using OAuth 2.0 server flow as seen in the documentation here https://v3.developer.constantcontact.com/api_guide/server_flow.html
This is all working fine and I'm able to get the access token and refresh the token every hour without problems.
But, when I attempt to do a curl post to add/update a contact in a list I get this message returned
Below is the url and headers I'm using $aTokenValue being the access_token
any guidance provided would be extremely helpful! Thank you in advance
I ended up debugging this with postman and there was an issue with my PHP curl request. Note to self and others who may see this - test with postman first!
Can you share your successful code please?
