Refresh Connection Schema

Refreshes a connection's cached schemas.

Call this when the upstream source has added, removed, or changed tables, objects, or fields and you need Polytomic to re-inspect the connection before creating or updating sync configuration.

This endpoint does not return the refreshed schemas directly. Follow the Location header or poll GET /api/connections/{id}/schemas/status until the refresh completes, then fetch the schemas you need.

📘 Schema refresh is asynchronous

This endpoint kicks off a background refresh of the connection's cached schemas and returns a Location header pointing at GET /api/connections/{id}/schemas/status. Poll that endpoint until cache_status transitions from refreshing to fresh (or until last_refresh_finished advances past last_refresh_started) to observe completion.

Only connections whose current health status is healthy may be refreshed.
