Overview
This article clarifies whether is possible to modify the identifier property after creating an API.
Solution
It is not possible to update the identifier property of an API.
When creating a new API, the New API modal specifically warns about this scenario.
There is no workaround for this.
The API would need to be recreated and the proper value configured.
This means that there is a need to update any application source codes to reference the newly created API details.
