WSO2 API Manager How to prevent subscriber freely subscribe to API but keep the API visible (how to add approval function before grant a subscription)
Could anyone assist on how to limit a subscriber to freely subscribe to an API? For example I have APIs called "contracts" and "parties", they are visible by user who has role "subscriber" hence subscriber can subscribes the both APIs. I would like to limit this so only authorized subscriber can subscribe to the API.
I understand that you can filter the API accessible by role - this is not the answer
I understand that you can block the subscription from publisher - this is also not the answer
Any advice would be greatly appreciated.
