Chatwork plans to update the Chatwork API for the Free Plan to remove the group chat limit and restrict message retrieval.
Changes
In the Free Plan, the limit of 7 group chats in total will be removed, allowing users to create and join 8 or more group chats via API.
In the Free Plan, viewable messages will be limited to the latest 5,000 messages posted within the past 40 days per organization, so some or all messages may not be retrievable via API.
When the message retrieval API returns restricted results, the response headers chatwork-message-limitation (set to true) and chatwork-message-limitation-summary will be added; if not restricted, both headers are omitted.
For retrieving the message list, the HTTP status code will be 200 when some messages are restricted, and 204 when all messages are restricted.
For retrieving a single message, the HTTP status code will be 404 when the specified message ID is restricted.
