# Polling

To set up an on-demand poll that will query the remote system for attachments and pass each to a subsequent poll, which will then retrieve them and pass them to Unifi to process, we will need to configure a further *two* *each* of the following records:

* Child Poll Processor
* Child Poller

*(Note: one of the children will be a parent to the other)*

We will also need to edit the previously configured [Child Poll Processor](https://docs.sharelogic.com/unifi/2.2/integration-guides/incident-parent-and-child-poller-guide/polling/child-poll-processor) *(per the Parent & Child Poller Guide)* to kick-off the first of our attachment Child Pollers.

To facilitate polling both the Table API and Attachment API, we will also need to make changes to the Endpoint URLs configured in earlier Guides in the following places:

* Connection
* Outbound Message Path
* Poll Processor Setup Script

We will look at each of those edits and the polling records in turn over subsequent pages. Before configuring those records, let’s first look at **Connection Variables**.
