Update Connection

Updates a connection's configuration. Updating a connection is a **full replacement** of its configuration. Any `configuration` field you omit is cleared. To make a partial change, fetch the current connection with [`GET /api/connections/{id}`](../../../api-reference/connections/get), apply your edits, and send the complete object back. > 📘 The connection is re-validated against the upstream service after every > update. The request will fail if the new credentials or endpoint cannot be > reached. Syncs that are already running when the update is submitted are not interrupted; the updated configuration takes effect on their next execution.
