# Operate

- [Bonding](/unifi/4.2/operate/bonding.md)
- [Bonds](/unifi/4.2/operate/bonding/bonds.md): Bonds store the data necessary to link your ServiceNow record to an external system.
- [Bonded Attachments](/unifi/4.2/operate/bonding/bonded-attachments.md): A Bonded Attachment is created for every synchronised attachment, storing relevant data.
- [Transport](/unifi/4.2/operate/transport.md)
- [Snapshots](/unifi/4.2/operate/transport/snapshots.md): Whenever there is an update to a bonded record, Unifi will take a snapshot of it and capture it in a Snapshot record. The Snapshot is the key to facilitating automated Integration testing.
- [Transactions](/unifi/4.2/operate/transport/transactions.md): A Transaction is an instance of a Message occurence.  It contains and tracks the processing of a Message using Stages and HTTP Requests.
- [Stages](/unifi/4.2/operate/transport/stages.md): The Stage is the root staging table for all data mapping.  Stages are created dynamically at the time of data being sent/received.  The Staged Data fields will vary dependent on the data being sent.
- [HTTP Requests](/unifi/4.2/operate/transport/http-requests.md): Every request is handled and tracked by a HTTP Request record.
- [Dataset Requests](/unifi/4.2/operate/transport/dataset-requests.md): Each Dataset Request stores the details and outcomes of a dataset import or export.
- [Poll Requests](/unifi/4.2/operate/transport/poll-requests.md): Each Poll Request stores the details and outcomes of a scheduled poll.
- [Error Handling](/unifi/4.2/operate/error-handling.md)
- [Integration Pause and Resume](/unifi/4.2/operate/error-handling/pause-and-resume.md): You can now Pause & Resume an Integration. This will cause Transactions to queue and then be processed in the order they were queued.
- [Integration Repair](/unifi/4.2/operate/error-handling/repair.md): The Repair feature allows you to manually replay all Transactions on an Integration which are in either an Error or Timed Out state.
- [Request Retry](/unifi/4.2/operate/error-handling/retry.md): Retry logic is configurable per Integration and controls how Unifi will automatically retry errored HTTP Requests.
- [Transaction & Request Replay](/unifi/4.2/operate/error-handling/replay.md): You can easily replay Requests and Transactions directly from the records themselves. This is an invaluable tool for debugging and error handling.
- [Transaction Ignore](/unifi/4.2/operate/error-handling/ignore.md): Setting Transactions to Ignored stops the queue from processing.
