# Fetch Data Source

> Trigger an immediate out-of-schedule import for a Google Merchant Center FILE data source

Trigger an immediate out-of-schedule import for a Google Merchant Center FILE data source. This starts ingestion; it does not retrieve data source information. API, UI, and AUTOFEED sources are not supported.

| ---------------- | -------------------- | -------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `account`        | DynamicAccount       | Yes      | -       | Select the Merchant Center account that owns the data source.                                                                                                                                                                                                                                                                                                                                                   |
| `data_source_id` | string or SelectItem | Yes      | -       | ID of a Google Merchant Center FILE data source to import immediately, outside its normal fetch schedule. This triggers ingestion; it does not retrieve the data source. Use gmc\_list\_data\_sources to find a source whose input is FILE. API, UI, and AUTOFEED sources cannot be triggered with this operation. Google recommends using the Products service when updates are needed more than once per day. |
