curl -X POST 'https://api.github.com/repos/example-owner/example-repo/git/trees' \  -H "Authorization: Bearer $GITHUB_TOKEN" \  -H 'Accept: application/vnd.github+json' \  -H 'X-GitHub-Api-Version: 2026-03-10' \  -H 'Content-Type: application/json' \  -d '{  "tree": [    {      "path": "example-path",      "mode": "100644",      "type": "blob",      "sha": "example-sha",      "content": "example-content"    }  ]}'

Parameters

Name	In	Type	Required	Description
owner	path	string	Yes	The account owner of the repository. The name is not case sensitive.
repo	path	string	Yes	The name of the repository without the `.git` extension. The name is not case sensitive.
tree	body	object[]	Yes	Objects (of `path`, `mode`, `type`, and `sha`) specifying a tree structure.
base_tree	body	string	No	The SHA1 of an existing Git tree object which will be used as the base for the new tree. If provided, a new Git tree object will be created from entries in the Git tree object pointed to by `base_tree` and entries defined in the `tree` parameter. Entries defined in the `tree` parameter will overwrite items from `base_tree` with the same `path`. If you're creating new changes on a branch, then normally you'd set `base_tree` to the SHA1 of the Git tree object of the current latest commit on the branch you're working on. If not provided, GitHub will create a new Git tree object from only the entries defined in the `tree` parameter. If you create a new commit pointing to such a tree, then all files which were a part of the parent commit's tree and were not defined in the `tree` parameter will be listed as deleted by the new commit.
