I'm setting up a REST call toward an external system to provide data out of a Business object to it.
The external system provided us with an API key and a HMAC to use for the connection.
When it is time to set up the communication scenario for the service, the API key field provided by the wizard of the Application Studio is only of 20 characters length.
The API key provided by the external system is of 56 characters.
Is there a way to extend the API Key field, or an alternative way to set up the call so that the 56 character length API key can be used?
