Data Deletion
How to delete threads and remove user information from Copilot via API.
Calling the DELETE /threads/:thread_id endpoint removes the association between the thread and your tenant.
The tenant and any user information attached to the thread (if provided) are replaced with a generic placeholder. Additionally, an anonymization pass is applied to the thread's messages to remove any remaining PII (names, addresses, etc.) — this applies when full anonymization was not already active in the assistant's configuration.
For more details on how anonymization works, see Anonymization.
