You are looking for the POST method for catalogSearch API call.
When using the below URL for POST method, it does not work:
Reproducing the Issue
1. Create your catalogSearch call and use the POST method
2. When you send the call, you get the below error:
There is no POST method for catalogSearch API call.
The catalogSearch call is meant for users to be able to search items in a Learning Catalog, so you can only use it with the GET method.
If you are looking for a call to add items in a catalog, we currently do not have any call that allows this. If this is a needed functionality, you may raise an Enhancement Request in our Community.
