# 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](/unifi/3.0/integration-guides/incident-parent-and-child-poller-guide/polling/child-poll-processor.md) *(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 may also need to *make changes to the Endpoint URLs\** configured in earlier Guides in the following places:\
\&#xNAN;*(\*only if the Connection contains the full endpoint url)*

* 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**.
