# createThread

> Create a new thread for a customer. Commonly used when a customer submits a contact form or when you want to start a proactive support interaction from your own product. The thread is created in `TODO` status. You can optionally set a title, priority, assignee, labels, thread fields, tenant, and an `externalId` for later lookup. Requires the `thread:create` and `thread:read` permissions.
