If you use an API or are thinking about it, one thing to keep in mind is the sending out of the Autoresponder Series and the Welcome Emails to new contacts. The good news is that when you are setting up your API, Constant Contact gives you the option to choose if contacts are being added by the actual contact or by the site owner (that’s you).
Per this post in our Developer Forums by our Elijah_G:
“In order to specify this, you must add the action_by query parameter with the value ACTION_BY_VISITOR to your POST request to create the contact. You can find the details on this parameter as well as additional information about creating a contact here.
This ACTION_BY_VISITOR is only available for adding individual contacts via the API.
Bottom line: If you’re using an API, make sure to set the above up when setting up your API, otherwise your newly added contacts won’t be receiving your valuable emails that you have already created for them! And if you have any API questions, check out our Developer Forums!
