Uploads SARIF data containing the results of a code scanning analysis to make the results available in a repository. For troubleshooting information, see "Troubleshooting SARIF uploads."

There are two places where you can upload code scanning results.

If you upload to a pull request, for example --ref refs/pull/42/merge or --ref refs/pull/42/head, then the results appear as alerts in a pull request check. For more information, see "Triaging code scanning alerts in pull requests."
If you upload to a branch, for example --ref refs/heads/my-branch, then the results appear in the Security tab for your repository. For more information, see "Managing code scanning alerts for your repository."

You must compress the SARIF-formatted analysis data that you want to upload, using gzip, and then encode it as a Base64 format string. For example:

gzip -c analysis-data.sarif | base64 -w0

SARIF upload supports a maximum number of entries per the following data objects, and an analysis will be rejected if any of these objects is above its maximum value. For some objects, there are additional values over which the entries will be ignored while keeping the most important entries whenever applicable. To get the most out of your analysis when it includes data above the supported limits, try to optimize the analysis configuration. For example, for the CodeQL tool, identify and remove the most noisy queries. For more information, see "SARIF results exceed one or more limits."

SARIF data	Maximum values	Additional limits
Runs per file	20
Results per run	25,000	Only the top 5,000 results will be included, prioritized by severity.
Rules per run	25,000
Tool extensions per run	100
Thread Flow Locations per result	10,000	Only the top 1,000 Thread Flow Locations will be included, using prioritization.
Location per result	1,000	Only 100 locations will be included.
Tags per rule	20	Only 10 tags will be included.

The 202 Accepted response includes an id value. You can use this ID to check the status of the upload by using it in the /sarifs/{sarif_id} endpoint. For more information, see "Get information about a SARIF upload."

OAuth app tokens and personal access tokens (classic) need the security_events scope to use this endpoint with private or public repositories, or the public_repo scope to use this endpoint with only public repositories.

This endpoint is limited to 1,000 requests per hour for each user or app installation calling it.
