Catalog API

Use Webhooks to Receive Catalog Notifications

The Catalog API supports the following webhook:

catalog.version.updatedThe catalog was updated. Webhook notification data is packaged as "catalog_version": { "updated_at": "2019-05-14T17:51:27Z"}.

Use the catalog.version.updated webhook to build real-time notifications that help you keep your catalog in sync.

The catalog.version.updated webhook sends an update when the seller's catalog is updated in any way. You can use this webhook as a notification to tell you when it is time to sync your catalog.

If you regularly poll SearchCatalogObjects for updates, you can use this webhook and increase the length of time between your polls.

This webhook sends a notification any time any catalog object is created, updated, or deleted.

For catalog.version.updated notifications, the data field includes a timestamp indicating when the catalog was last updated.

You do not need to use the updated_at timestamp from the webhook in the recommended sync flow. It is provided for convenience, but the value you pass to SearchCatalogObjects is the timestamp of the last time you synced.

When you receive a catalog.version.updated notification, call the SearchCatalogObjects endpoint and set the begin_time field to the timestamp of the last time you synced your catalog. This retrieves all the CatalogObjects updated after the timestamp listed in begin_time.

You should store the latest_time value returned by the SearchCatalogObjects endpoint, so you can use it in your next call to SearchCatalogObjects. Using a locally generated timestamp might cause you to miss updates as a result of time skew between the Square server and your application.

A sample call to SearchCatalogObjects is as follows:

Search Catalog Objects

    "begin_time": "BEGIN_TIME"
