Direct Messages enable private conversations on X. Direct Messages are one of the most popular features of X, with a wide variety of use cases. These use cases range from group chats among friends, to powering customer support for brands around the world. New v2 versions of Direct Messages endpoints will be introduced in stages, and this first stage includes fundamental endpoints for creating Direct Messages and listing Direct Message conversation events. For the first time, the X API v2 supports group conversations. This initial release of Manage Direct Messages includes three POST methods for creating Direct Messages:
  • POST /2/dm_conversations/with/:participant_id/messages - Creates a one-to-one Direct Message. This method either creates a new 1-1 conversation or retrieves the current conversation and adds the Direct Message to it. The :participant_idpath parameter is the User ID of the account receiving the message. 
  • POST /2/dm_conversations - Creates a new group conversation and adds a Direct Message to it. These requests require a list of conversation participants. Note that you can create multiple conversations with the same participant list. These requests will always return a new conversation ID. 
  • POST /2/dm_conversations/:dm_conversation_id/messages - Creates a Direct Message and adds it to an existing conversation. The :dm_conversation_id path parameter is the ID of the conversation that the message will be added to. 
Note that Direct Message event IDs are common across the v1.1 and v2 (as well as the X App), so the v1.1 methods to hide/delete Direct Messages can be used along with this new v2 endpoint. Also note that the Enterprise and Premium Account Activity APIs support v2 one-to-one messages, but do not yet support group conversations.    There is a user rate limit of 200 requests per 15 minutes for the POST method. There is also a rate limit of 1000 requests per 24 hours per user. Additionally, there is a rate limit of 15000 requests per 24 hours. Note that these rate limits are shared across these POST endpoints. Since you are making requests on behalf of a user with the manage Posts endpoints, you must authenticate with either OAuth 1.0a User Contextor OAuth 2.0 Authorization Code with PKCE, and use a user Access Tokens associated with a user that has authorized your App. To generate this user Access Token with OAuth 1.0a, you can use the 3-legged OAuth flow. To generate a user Access Token with OAuth 2.0, you can use the Authorization Code with PKCE grant flow).
