I am currently learning to use API on BC On-prem,
I've followed the guide from this link https://learn.microsoft.com/en-us/dynamics365/business-central/dev-itpro/developer/devenv-develop-custom-api
I even use the same objectname and and field. But I cannot get the respon from postman.
I can call the standard API, but not the custom one.
I already check on table Metadata it's already listed there but I still unable to call it.
**SOLVED Thank you ZHU.
Turned out the root cause is because the request URI missing API publisher and API group.
Missed it because I did comparing with the standard API which didn't not use the them.
