Do wildcards still work?

0 Votes

This post says wildcards work on subdomains:


This one mentions it's deprecated in certain places:


Is there documentation/examples on what is actually supported?


I just tested the following, which was accepted by the UI but didn't work: 


I had to change it to: 

And that worked. 


Is it not working because the wildcard is on a 2nd level subdomain or because wildcards are now simply deprecated?

Hello JasonK108,


Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.


I can confirm that wildcards are only supported in the redirect URI at the lowest level subdomain. Wildcards can’t be used to pass query parameters or specify a port. 


That being said, we are currently investigating an issue where redirect URIs with a wildcard in the lowest level subdomain work successfully with authorization requests when the wildcard character is included in the redirect URI being sent in the request, but result in a 400 error response when the wildcard character is replaced with a variable. We will post again in this thread as soon as we have an update on this issue.


Please have a look and let us know if you have any other questions!
