We designed Merchant API to be familiar to Content API for Shopping developers,
yet simpler and more flexible. Here's some detailed information on the design of
Merchant API.
Sub-APIs
Merchant API is a collection of sub-APIs. The sub-APIs are groups of related
services and resources. This design means you can choose to use only the
sub-APIs needed for your unique integration.
Merchant API includes the following sub-APIs:
Accounts: Manage Merchant
Center accounts at scale.
Conversions:
Manage conversion sources for your account.
Data sources: View and
manage the data sources for your products.
Issue resolution: Obtain
issues impacting your account and create an in-app diagnostics page.
Inventories: Showcase your
products by store or region on Google.
Enum fields across Merchant API might be exposing new values in the future. Your
code should be structured in such a way that it can handle unrecognized values
gracefully. You should monitor the occurrence of unrecognized enum values and
intervene to keep the code up to date.
Versioning
Sub-APIs are versioned separately. This means you don't need to do anything if
we update a sub-API that you don't use. You only need to update your code when
new versions of the sub-APIs you use are released. For more information, see
Versioning.
Versions that end in "beta" are subject to change or removal.
