# Polling domain-specific events with Response Queue

The Response Queue allows you to poll domain-specific events. This is useful when you have Engage with more than one domain.

## How it works

- If you have a multi-domain Engage system, you can query the Response Queue for events from each domain specifically by using the correct domain, or `sysname` in the API request endpoint.
- Only events for the specific domain from which you are querying are retrieved from the Response Queue.
- With this feature activated, you are obligated to poll events using specific domains. For example: Your Engage domains are `a.com`, `b.com` and `c.com`. If you want to poll events specific to the `b.com` domain, you need to change the endpoint to call the `b.com` Engage domain. Consequently, code changes will be required for the API requests you send to poll the Response Queue.

> - Example Request & Response for each method will stay the same.
> - All methods under the asynchronous domain will be affected by this change.
> - If this feature is disabled at a later point, the user won't be able to get past data that was saved in Response Queue when the feature was enabled.

## Example

Consider a multi-domain system with `subdomain1.domain.com` and `subdomain2.domain.com`.

You want to poll responses from *subdomain1*. This means that your REST request must be executed with *subdomain1.domain.com* as realm/domain.

## Prerequisites

- This feature needs to be activated by your customer success or account manager.
- Requires minimum API 2.0 WADL/WSDL version 13.
