Issue/Question

Is it possible to transfer API Definitions between collections, without deleting and recreating the API definition?

Is there any possibility to do this via API, if not possible via UI?

Solution/Answer

You can do this with direct API calls.

For instance, for API whose ID is <API_UUID>, to move it to collection whose ID is <Collection_UUID>, you would do a PUT on https://<platform_name>/api/v2/apis/<API_UUID>  with the following body:

{
"cid":"<Collection_UUID>"
}
