Available actions
Insert Product Add a product to an API data source of the connected Merchant Center account. If the data source already has an entry with the same product_id, content_language and feed_label, the new entry replaces it. data_source is the data_source_id or data_source_name of an API data source (Data Sources table, or create one with create_data_source). In a primary data source, give the attributes that Google needs to show the product, for example title, link, image_link, price, currency and availability. Merchant Center shows the change after a few minutes. Remove the product with delete_product.

Update Product Change the given attributes of a product in an API data source of the connected Merchant Center account. Attributes that are not given keep their values. product_id, content_language and feed_label come from the product_id, product_content_language and product_feed_label fields. data_source is the data_source_id or data_source_name of an API data source: the product's primary data source (product_data_source) if its input is API, otherwise a supplemental API data source that is linked to that primary data source (create one with create_data_source and link_to_primary_data_source). Values of a supplemental data source that comes before the feed in the feed's default rule (as create_data_source links it) override the feed values until delete_product removes them from the supplemental data source. clear_attributes deletes attributes from the product in data_source: in a supplemental data source the product then shows the feed value again. pause ADS or ALL pauses the product, NONE ends the pause. Merchant Center shows the change after a few minutes.
