# Data catalogs and the Vantage API

> List, inspect, update, reindex, and delete data catalog records via the Vantage API.

Manage data catalogs programmatically using the Vantage API — list catalogs, inspect their structure, add records, reindex after changes, and delete records.

## List and inspect data catalogs

* List all available data catalogs:

  ```
  GET https://your-instance.vantage.abbyy.com/api/publicapi/v1/catalogs
  ```

* Get detailed information about a specific data catalog:

  ```
  GET https://your-instance.vantage.abbyy.com/api/publicapi/v1/catalogs/{catalogId}
  ```

* Get the mapping between a skill's fields and a data catalog's columns:

  ```
  GET https://your-instance.vantage.abbyy.com/api/publicapi/v1/{skillId}/catalogsMapping
  ```

## Update a data catalog

Use the following endpoints to update a data catalog with JSON records.

<Steps>
  <Step title="Add records">
    Send a **POST** request to the **records** resource:

    ```
    POST https://your-instance.vantage.abbyy.com/api/publicapi/v1/catalogs/{catalogId}/records
    ```
  </Step>

  <Step title="Reindex">
    Once updates are complete, reindex the catalog so new data becomes searchable:

    ```
    POST https://your-instance.vantage.abbyy.com/api/publicapi/v1/catalogs/{catalogId}/reindex
    ```

    <Warning>
      Without this reindex request, searches return data from the outdated version of the data catalog.
    </Warning>
  </Step>

  <Step title="Check reindex status">
    Use the operation ID returned from the reindex request to check status:

    ```
    POST https://your-instance.vantage.abbyy.com/api/publicapi/v1/catalogs/{catalogId}/reindex/reindexOperationId/download
    ```
  </Step>
</Steps>

After indexing completes, the catalog is ready for use by Document skills.

## Delete all records

Remove every record from a data catalog:

```
POST https://your-instance.vantage.abbyy.com/api/publicapi/v1/catalogs/{catalogId}/records/delete/download
```
