Add tag ID to new contact

I’ve got a wordpress form that sends a new lead to the contact list. This is all working perfectly:

Get the keys > build the data array > send the data > post thank you message

What I want to do is add a tag to the new contact but there doesn’t seem to be a simple way to do this. One thread says I need a separate API call and the documentation will be updated to reflect this but it doesn’t appear to have happened.

In any case, adding a new contact doesn’t return the contact ID. I’m using:


Where $fields is the data array.

Any clues as to how to fix this?

The API definitely returns the contact id on add, but maybe the SDK is not exposing this. I am not a PHP guy, but if you can get the raw XML response you should be able to get it.
