It worked using this. After I used this I took the result URL and pasted in my code.   $url = 'https://api.cc.email/v3/activites/add_list_memberships'; $url = 'https://api.cc.email/v3/activities/add_list_memberships';   The url is different. 'activites' vs 'activities' I check the documentation doc here: https://v3.developer.constantcontact.com/api_guide/lists_overview.html And sure enough the URL is not spelt correctly.. Example Request - POST add_list_membership This call adds five existing contacts to two lists. The contacts are specified in thesource object contacts array of contact_id’s. POST https://api.cc.email/v3/activites/add_list_memberships There seem to be another typo in the above as well. 'thesource' I guess should be 'the source' This has caused me great pain. Its working now. ... View more

Hey  Jimmy Yeah the URL is correct. ATM its hard coded to elimiate this as a problem. $url = 'https://api.cc.email/v3/activites/add_list_memberships'; print_r('before add to list<br />'); $results = $this->queryAPI($url, [], 'POST', $c_data, true); The process is the same for each call. Just different values. The calls to check for the contact is working and such. The only call that is failing is 'https://api.cc.email/v3/activites/add_list_memberships'. I've also outputted the URL just before the call to make sure. Anything else that can be causing this? ... View more

Hi Jimmy Thanks for the quick reply! In my defence the docs are the first place I looked and looked again. https://v3.developer.constantcontact.com/api_guide/contacts_create.html   I cannot find any mention of a create_source here. And states it only need one of the 3 parameters. first_name, last_name and/or email_address. I was also unable to find any reference to the method you have used to add contacts at the same time as adding it to a list.  From what I can see here  https://v3.developer.constantcontact.com/api_guide/lists_overview.html I need to pass contact_id when adding to a list. In fact I cannot find any references to the method you are using. In addition your method fails when adding a contact that already exists. Unfortunantly This does not work with the flow I need. So using your code as reference I am able to add in a contact. So the flow of the app goes as follows. - Check if contact exists. - If not create contact - Use the contact ID and add that contact to the select list. Now I cannot add a contact to a list. Im following this here to add contacts to a list https://v3.developer.constantcontact.com/api_guide/lists_overview.html Passing to 'https://api.cc.email/v3/activites/add_list_memberships' {#866 ▼ +"source": array:1 [▼ "contact_ids" => array:1 [▼ 0 => "75a8a350-2fab-11e9-9c34-d4ae5275505f" ] ] +"list_ids": array:1 [▼ 0 => "28a40610-1f9f-11e9-a7ee-d4ae528eb27b" ]} And the return is array:1 [▼ 0 => array:2 [▼ "error_key" => "not_found" "error_message" => "The requested resource was not found." ]] Any ideas what is wrong now? ...
