`POST` Publish a Catalog

https://api.moltin.com/pcm/catalogs/:catalogId/releases

Publishes a catalog. You must publish a catalog before you can retrieve that catalog in a store. The hierarchies, live products, and prices associated with a published catalog are in read-only mode. If you make a change to these resources, for example, a change to your price book or hierarchies, you need to republish the catalog.

You can get a catalog release to retrieve a published catalog. Currently, published catalogs are limited to the current release and two releases prior to the current release.

You can see the differences between the last 2 consecutive catalog releases. This is useful if want to understand how your products have changed in your catalog, ensuring your site search integration is kept up-to-date.

Once a catalog-release has completed publishing, the delta relationship links to the delta document.

      }
    }
  }
}

The delta links are signed and only valid for 1 hour. Re-reading a catalog release, for example, using Getting a release of a catalog returns a fresh a link.

You can use the is_full_delta attribute returned from the get a release of a catalog endpoint to determine if you need to refresh the data in your company system before injecting fresh data in a delta link. The is_full_delta attribute tells you if this is a full publish of the catalog. Using a search service as an example, if the is_full_delta attribute is true, you should remove all data about that catalog from the search service before injecting fresh data from the delta file. If the is_full_delta attribute is false, then data from the previous catalog overlays the existing data in the delta file. To publish a catalog and inject fresh data in a delta link, set export_full_delta to true.

Generating a full delta is resource intensive and slows down the publishing process and so should only be performed in certain circumstances, for example, when initializing an integration with a service like Algolia.

The is_full_delta attribute is always true the first time a catalog is published.

The information is stored in a collection of json documents in a compressed file. You can either manually check the file or, for example, use them to automatically update another company system you may have. Files are:

Only available for 30 days.
Removed when a catalog release is deleted.

Each document has a delta_type with one of the following values, depending on whether a product has been deleted, updated or created in a catalog release.

delete describes products deleted from this release of a catalog.
createupdate describes products updated in this release of a catalog.

An example of a file is shown below.

Headers

Name	Required	Type	Description
`Authorization`	Required	`string`	The Bearer token required to grant access to the API. Note that this must be a client credentials token.

Body

Name	Required	Type	Description
`export_full_delta`	Optional	`boolean`	Set to `true` if you want to inject fresh data in a `delta` link. You can use the `is_full_delta` attribute returned from the `get a release of a catalog` endpoint to determine if you need to refresh the data in your company system before injecting fresh data in a `delta` link. The `is_full_delta` attribute tells you if this is a full publish of the catalog.
