As an alternative to running code scanning within GitHub, you can perform analysis elsewhere and then upload the results. Alerts for code scanning that you run externally are displayed in the same way as those for code scanning that you run within GitHub. For more information, see "Managing code scanning alerts for your repository."
If you use a third-party static analysis tool that can produce results as Static Analysis Results Interchange Format (SARIF) 2.1.0 data, you can upload this to GitHub. For more information, see "Uploading a SARIF file to GitHub."
If you run code scanning using multiple configurations, then sometimes an alert will have multiple analysis origins. If an alert has multiple analysis origins, you can view the status of the alert for each analysis origin on the alert page. For more information, see "About analysis origins."
Integrations with webhooks
You can use code scanning webhooks to build or set up integrations, such as GitHub Apps or OAuth Apps, that subscribe to code scanning events in your repository. For example, you could build an integration that creates an issue on GitHub or sends you a Slack notification when a new code scanning alert is added in your repository. For more information, see "Creating webhooks" and "Webhook events and payloads."
