Get started with the Merchant API

Enable the Merchant API in your Cloud project to get started.

Here's how to use the Merchant API:

Use client libraries

The Merchant API is made of multiple sub-APIs.

Each sub-API has code samples and client libraries to help you get started.

If you already use the Content API for Shopping, see Content API for Shopping compatibility.

Send requests

Send requests to URLs in the following format:

https://merchantapi.googleapis.com/{sub-API}/{version}/{resource name}/{service}:{method}…

Where {resource name} is the name of the resource your call impacts.

For example, here's how to delete regional inventory with gRPC:

https://merchantapi.googleapis.com/inventories/v1beta/{resource name}/regionalInventories:delete

Here's how to delete regional inventory with REST:

DELETE https://merchantapi.googleapis.com/inventories/v1beta/{resource name}/regionalInventories

See the Merchant API reference documentation for more details on specific services.

Use gRPC or REST

The Merchant API supports gRPC and REST. Here are the two ways to make Merchant API calls:

gRPC (recommended)	REST
Create the body of the request as a protocol buffer. Send the request body to the server with HTTP/2. Deserialize the response to a protocol buffer. Interpret the results.	Create the body of request as a JSON object. Send it to the server using HTTP 1.1. Deserialize the response as a JSON object. Interpret the results.

Note: If you use a client library, the default transport mechanism is gRPC. In most cases you don't need to do anything other than call the Merchant API endpoints to use gRPC.
