This version of GitHub Enterprise Server will be discontinued on 2024-03-07. No patch releases will be made, even for critical security issues. For better performance, improved security, and new features, upgrade to the latest version of GitHub Enterprise Server. For help with the upgrade, contact GitHub Enterprise support.

After a site administrator upgrades your Enterprise Server instance to Enterprise Server 3.9 or later, the REST API will be versioned. To learn how to find your instance's version, see "About versions of GitHub Docs". For more information, see "About API versioning."

Upload a release asset

This endpoint makes use of a Hypermedia relation to determine which URL to access. The endpoint you call to upload release assets is specific to your release. Use the upload_url returned in the response of the Create a release endpoint to upload a release asset.

You need to use an HTTP client which supports SNI to make calls to this endpoint.

Most libraries will set the required Content-Length header automatically. Use the required Content-Type header to provide the media type of the asset. For a list of media types, see Media Types. For example:

application/zip

GitHub Enterprise Server expects the asset data in its raw binary form, rather than JSON. You will send the raw binary content of the asset as the request body. Everything else about the endpoint is the same as the rest of the API. For example, you'll still need to pass your authentication to be able to upload an asset.

When an upstream failure occurs, you will receive a 502 Bad Gateway status. This may leave an empty asset with a state of starter. It can be safely deleted.

Notes:

  • GitHub Enterprise Server renames asset filenames that have special characters, non-alphanumeric characters, and leading or trailing periods. The "List release assets" endpoint lists the renamed filenames. For more information and help, contact GitHub Enterprise Server Support.
  • To find the release_id query the GET /repos/{owner}/{repo}/releases/latest endpoint.
  • If you upload an asset with the same filename as another uploaded asset, you'll receive an error and must delete the old file before you can re-upload the new asset.
