Tracking codes?

How do I add a tracking for to my thank you page?

If you would like to insert a tracking pixel code, the code can be added to the source of the Thank You Message. Only HTML tracking codes are supported, script codes are stripped.

You can also use Google Analytics widget. 

We also have Form Analytics feature.
