Response Body
application/json
curl -X POST "https://example.com/api/v1/messages/lgm_Zm9vYmFyYmF6cXV4/reaction" \ -H "Content-Type: application/json" \ -d '{ "reaction": "string" }'{ "object": "MessageReactionAdded", "success": true}Answer a checkpoint POST
Types `code` (an email/SMS code, an authenticator code, or a phone number for `PHONE_REGISTER`) into the sign-in still waiting on the checkpoint page. The answer is the next stop: signed in (201 `AccountCreated`, also for a reconnect), another checkpoint (202: LinkedIn chains them), or an error. A code LinkedIn did not accept is 401 `code-rejected` (`errors/invalid_checkpoint_solution`): the sign-in still waits for the right one. 408 `no-attempt` means the sign-in is gone: connect again.
Delete a chat DELETE
A write (`message`). The conversation leaves the member's inbox; LinkedIn's delete is one-sided, the other member keeps it.
