# Polling

- [Pollers](/unifi/3.1/polling/pollers.md): A Poller makes a scheduled request to a remote system.
- [Poll Processors](/unifi/3.1/polling/poll-processors.md): Poll Processors are used to setup, execute and process Poll Requests.
- [Poll Requests](/unifi/3.1/polling/poll-requests.md): Each Poll Request stores the details and outcomes of a scheduled poll.
- [Large Response Payloads](/unifi/3.1/polling/large-response-payloads.md): If you're building a polling integration that has response payloads larger than 5MB then you'll need to save them as attachments and adapt your response processing.
