# Create post comment

Any user associated with a context with `AUTHENTICATED` scope can add a comment to the own post or
to a post created by any user from the network by executing of the `createPostComment` mutation.
The current API user will be set as an author.

Mutation has a single required incoming argument - `data` that represents `PostCommentCreationInput` object:
