With Tyk Gateway, is it possible to have an api, with multiple customers, and enforce a quota_max of 100 per customer, where the customer can generate multiple keys, where keys shared the same quota, so say key1 makes 10 requests, key2 makes 20 requests, remaining quota should be 70 for both keys
Hi @sarp,
Thank you for your patience and welcome to the community 
Currently, this limit can be applied at the Organisation level, affecting all APIs/keys within the Organisation, as the quota is shared across them.
Please see more about this under “Organisation Quotas” in the Gateway API Documentation.
