asp.net core - C# - Azure API - pushes - method not allowed error - Stack Overflow

I try to create the first commit and the main branch, in c#, calling ADO api on my server

but I am not sure this can be done as I get "MethodNotAllowed" return code

PAT is full access and POST should be the way to make a push

when I trace the code, the end point is :

https://*********/_apis/git/repositories/******-****-****-****-************/pushes?api-version=7.1-preview.1

(note that the obfuscated repository id above is valid and used for other working requests)

here is the code :

public async Task<bool> CreateFirstCommitAndMainBranchAsync(string repositoryName, string readmeContent)
{
    string endpoint = $"https://{m_adoSspServer}/_apis/git/repositories/{repositoryInfos.Id}/pushes?api-version=7.1-preview.1";

    var commitData = new
    {
        commits = new[]
        {
            new
            {
                comment = "Initial commit with README.md",
                changes = new[]
                {
                    new
                    {
                        changeType = "Add",
                        item = new

            }
        }
    };

    string jsonContent = JsonConvert.SerializeObject(commitData);

    using (var client = new HttpClient())
    {
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Basic",
            Convert.ToBase64String(Encoding.ASCII.GetBytes($":{pat}")));

        var response = await client.PostAsync(endpoint, new StringContent(jsonContent, Encoding.UTF8, "application/json"));

        if (response.StatusCode != System.Net.HttpStatusCode.OK)
        {
            Console.WriteLine($"Failed to create commit and branch: {response.StatusCode} - {response.ReasonPhrase}"); // MethodNotAllowed
            return false;

Commit can be done as the official document https://learn.microsoft.com/en-us/rest/api/azure/devops/git/pushes/create?view=azure-devops-rest-7.2&tabs=HTTP.

I tested your code and get the same error.But after change to latest version to "api-version=7.2-preview.3" it works.
I think it is because they didn't fix the old preview vesion anymore. Cause "api-version=7.1" also works.
