API
A customer support API for Slack-first teams.
Use the cxthread API to create or reply to tickets per inbox—then let agents handle everything inside Slack threads.
Use cases
The API is the clean way to make cxthread more than “email → Slack”. You can programmatically open tickets, append messages, and keep everything in the same Slack-native workflow.
In-app “Contact support”
Turn an in-app form submission into a Slack thread in the right inbox.
Alerts & incidents
Send billing failures, outages, or escalations into support with an external ID for traceability.
Internal tools
Let ops or engineering open tickets from internal systems without leaving Slack.
Learn the endpoints
The MVP supports programmatic ticket creation and replies. API messages appear in Slack as “API message from …” inside the inbox’s configured channel/thread.
