Can Edge micro gateway services make a call to BAAS api's ?
Technically possible. But I would refrain from it. MG is not a good place to implement APIs.
@Srinandan Sridhar....Thanks for the input. Are you suggesting that MG is not a good place to implement APIs or you meant that implementing MG API's which involve call to Edge BAAS is not a good/suggested approach...
In general, MG is not a good place to implement APIs (BaaS or otherwise).
