I am writing an app that connects to Constant Contact API. I noticed that whenever I tried to pass an email address with pluss addressing (firstname.lastname@example.org), API does not parse it and returned null.
Do I need to encode it first? Or does the API does not support it?
I was using the GetContacts API call (https://developer.constantcontact.com/api_reference/index.html#!/Contacts/getContacts)
I noticed that it passes email address as a URL query string, so it has to be URL encoded first.
$email = urlencode($email);
Thank you for reaching out to Constant Contact API Developer Support.
