I have an API Product and want to assign multiple rate plans to it like Freemium, PrePaid and PostPaid at the same time. As per the APIGEE Edge and/or Apigee X documentation, an API product can have multiple rate plans but only one can be active at a time. It also talks about Developer Categories and assigning rate plans for each Developer Category when selecting the API product. My question is can I create multiple Developer Categories and have same Developer(or Developers) in each one of them and assign different rate plans to them under the same API product in order to achieve my goal of having multiple rate plans for an API product? (If this is not possible then please mention if there is an alternate way to this approach). Many thanks.
