The `entitiesToSync` object replaces your app's optional selection for this credential. Include all optional types you still need. Saving resets the connection's sync; allow the data to sync before expecting complete results. ## OpenAPI ````yaml /openapi/rollout.json put /credentials/{credentialId} openapi: 3.0.3 info: title: Universal API Documentation description: Development documentation version: '1.0' servers: - url: https://universal.rollout.com/api security: [] paths: /credentials/{credentialId}: put: tags: - Credentials summary: Update Credential description: >- Changes the optional data types synced for an existing connection; see [the configuration example](https://rollout.com/docs/advanced-guides/controlling-which-records-sync-with-rollout#through-the-api).
