1. Fetch latest commit to get reference

GET /repos/{{owner}}/{{repo}}/git/ref/heads/{{branch}}

Save body.object.sha from response as reference_sha.

2. Create a tree

POST /repos/{{owner}}/{{repo}}/git/trees

Body

{
  "base_tree": "{{reference_sha}}",
  "tree": [
    {
      "path": "{{filename}}",
      "mode": "100644",
      "type": "blob",
      "content": "hello world"
    }
  ]
}

Save body.sha from response as tree_sha.

3. Create a commit

POST /repos/{{owner}}/{{repo}}/git/commits

Body

{
  "message": "commit message",
  "parents": ["{{reference_sha}}"],
  "tree": "{{tree_sha}}"
}

Save body.sha from response as commit_sha.

4. Update the reference

PATCH /repos/{{owner}}/{{repo}}/git/refs/heads/{{branch}}

Body

{
  "sha": "{{commit_sha}}"
}

DONE! 🥳
