post
https://api.community.com/subcommunities
Creates a subcommunity in the community associated with your API key. Only title is required. It must be unique within your community.
A new subcommunity has no members. Members can join on their own by texting one of the subcommunity’s keywords, or you can add them with [assign endpoint].
The response is a Subcommunity object.
Retries
Because titles must be unique, retrying a request that already succeeded returns an error instead of creating a duplicate. If you get [error code] on a retry, your original request worked.
