Get Bulk Source

Lists the schemas (tables or objects) available on a connection for use as a bulk sync source, optionally including per-schema field details. The response reflects what the connection currently has cached; if the upstream source has changed, trigger a refresh first with [`POST /api/connections/{id}/schemas/refresh`](../../../../../api-reference/schemas/refresh). These are the schemas available for selection, not the schemas already configured on any particular sync. To inspect schemas on a running sync, use [`GET /api/bulk/syncs/{id}/schemas`](../../../../../api-reference/bulk-sync/schemas/list). Pass `include_fields=true` to receive per-schema field details in a single call. Omit it when you only need the schema list, as field enumeration can be slow for large sources.
