# Pub/Sub API Endpoints

Pub/Sub API provides a global endpoint and a region-specific endpoint.

The endpoints include the port. Replace the `{port}` placeholder with the port that Pub/Sub API uses: `443` or `7443`. For example, the global endpoint with the `443` port is `api.pubsub.salesforce.com:443`.

## Global Endpoint

Use this endpoint if you don't have data in transit privacy requirements for your org.
To help reduce API request latency, the Pub/Sub API service attempts to process requests in the same region where they originate.

```
api.pubsub.salesforce.com:{port}
```

## Europe Endpoint

Use this endpoint if you must comply with data in transit privacy requirements for your org. Using this endpoint ensures that Pub/Sub API event processing occurs via the Salesforce service located in Germany.

```
api.deu.pubsub.salesforce.com:{port}
```

Events in the Salesforce event bus aren’t persisted or stored outside the region your org is located in. For more information about the regions where event processing occurs, see [AWS Regions](/docs/platform/pub-sub-api/guide/considerations.md#aws-regions).

:::note
If your company uses a firewall for network security, make sure that the Pub/Sub API endpoint is allowed in the firewall configuration. Allow the entire domain and port. For example, for the global endpoint, the domain is `api.pubsub.salesforce.com`, and the port is `443` or `7443`. Don’t use hardcoded IP addresses in your allowlist because they can change. Also, allow the HTTPS and TCP protocols.
