How do I customize the thank you page of my Donations modal popup?

When a Donation page is used as a Donations modal popup, the thank you page that is displayed in the popup differs from that shown in the standard version of the form.

To customize the thank you page of a Donations modal popup:

1. Open the Donations form you are using for the Donations modal popup
2. Click the Integration tab
3. For Popup Thank You Text, enter the text you wish to display on the thank you page. NOTE: No merge fields are supported at this time.
4. Click Save
