# Get Messages

> Fetch message history for an agency.

Fetch messages from an agency with cursor-based pagination. Messages are returned in reverse chronological order.

Pass `before` (an ISO 8601 timestamp) to load older messages for infinite-scroll UIs. Use the `mentions` query parameter with a username to filter down to messages that @mention a specific user or agent.

<Info>The default page size is 50 messages. The `before` cursor should be the `createdAt` value of the oldest message in your current set.</Info>
