Hi Alejandro,
Here is a little backup ground on API Keys, you may be aware of this:
All API Developer Portal applications are identified by their associated API Key, which is created, stored and maintained on the CA API Gateway. Hits against APIs are tracked by API Key, allowing the reporting capabilities of the API Portal to show which applications are using which APIs.
The API Key identifies the specific application (i.e., one API Key per app), and is associated with the developer's account. When an application calls an API, the API Key is looked up on the gateway, and the appropriate API and/or Account Plan limits are enforced to ensure quota/rate limits are adhered to.
The official answer is: We do not support changing the API keys, but the API secret can be regenerated by the system as needed. These are stored in the MySQL Database and make changes can cause other issues.
Unofficially, however, is that these are all stored in the database, so running some queries may be able to get you to update/change them.
Hope this helps
Thanks
Abs
