A way to edit an existing comment on the API using /apis/{apiId}/comments

[selakap]

Describe your problem(s)

Expect a way to edit an existing comment on the API. In the current implementation, we cannot do such an update using the POST restful API [1].

1. https://apim.docs.wso2.com/en/3.1.0/develop/product-apis/devportal-apis/devportal-v1/devportal-v1/#/Comments/addCommentToAPI

Describe your solution

Introduce a PUT resource to /apis/{apiId}/comments

[thisaltennakoon]

We cannot edit comments from the publisher and devPortal because we have not implemented that in the front end. However, back-end support is there for both portals(See [1] and [2]).
