We are working on a Software as a service platform in which we would want to create apis for other businesses to consume in the banking domain. Now for them to integrate these apis in their applications we want to give them two different environments, test and live. The users can generate their client_key and client_secret for these two environments separately and then consume the apis. The data source should be different for both of them while the api stack would be the same. How can we implement this in a way that when a request comes to our Xano server it routes it to the correct data source on the basis of the client_key (client keys would contain the keyword test or live as the suffix)?
