An agent operating many inboxes gets every conversation in one call instead of one call per inbox. Each thread carries its own `inbox_id` so a reply can be routed back to the right inbox. Use `filter[inbox_id]` (repeatable) to narrow the result to specific inboxes. Because a thread ID can be delivered to multiple inboxes, each result is identified by its `(inbox_id, id)` pair. ## OpenAPI ````yaml /openapi/generated/email/inboxes.yml get /email_threads openapi: 3.1.0 info: contact: email: support@telnyx.com description: API for managing email inboxes, drafts, messages, filters, and threads. title: Telnyx Email Inboxes API version: 2.0.0 servers: - url: https://api.telnyx.com/v2 security: - bearerAuth: [] paths: /email_threads: get: tags: - Email Threads summary: List threads across every inbox in the account description: | Lists thread summaries for the whole account, newest first, using stable cursor pagination.
