# GetTopic RPC Method

The `GetTopic` RPC method returns information for an event, such as the event topic name and the schema ID. The topic is the API name of the event object preceded by a path. The topic indicates the type of event to publish and the type of event to subscribe to. For example, the topic of a custom platform event with the API name of `Order_Event__e` is `/event/Order_Event__e`. Pass in the topic name in `TopicRequest`. The schema ID, that's returned in `TopicInfo`, is used to get the event schema with `GetSchema`.

```
rpc GetTopic (TopicRequest) returns (TopicInfo);
```

For more information about the fields in TopicRequest and TopicInfo, see the [Pub/Sub API proto file](https://github.com/forcedotcom/pub-sub-api/blob/main/pubsub_api.proto).
