GitHub API returning 404 although resource exists - github

I'm trying to send a POST request to the GitHub API to submit a comment on a commit.
According to the documentation, all that's needed (other than the URL params) is the body.
I have modified the example from the docs to the following:
curl \
-X POST \
-H "Accept: application/vnd.github.v3+json" \
https://api.github.com/repos/dchacke/test/commits/9b7413350932dd3f2906c0fdd26106c35c7ce450/comments \
-d '{"body":"test comment"}'
That should post a test comment to this commit. I know the commit and the owner and repo exist (it's my repo and I can see the commit under that URL), and yet I'm getting a 404 with the following response body upon submitting that API request:
{
"message": "Not Found",
"documentation_url": "https://docs.github.com/rest/reference/repos#create-a-commit-comment"
}
The documentation makes no mention of authentication being required for that endpoint. A 404 doesn't exactly sound like an authentication problem, but just in case GitHub doesn't want to confirm the existence of repos/commits to unauthenticated users (though they do let them see those things on their website...), I tried setting a personal access token in an additional Authorization header in my CURL request. No dice.
What am I doing wrong?

Authentication was the issue after all. I had to make sure I used a token with the right privileges. In this case, it needed the public_repo privilege, which can be set up here.

Retrieve artifacts from public repository using PAT

I am trying to download the latest artifact of a repository I don't own.
The API just gives me the following error:
{
"message": "You must have the actions scope to download artifacts.",
"documentation_url": "https://docs.github.com/rest/reference/actions#download-an-artifact"
}
The thing is, I don't see an "actions" box in when creating a personal access token. Here are the possible options, my token has access to "repo" and "workflow"
Is this on purpose, or have I missed something (another endpoint)?
As mentioned in the documentation:
Check headers to see what OAuth scopes you have, and what the API action accepts:
$ curl -H "Authorization: Bearer OAUTH-TOKEN" https://api.github.com/users/codertocat -I
HTTP/2 200
X-OAuth-Scopes: repo, user
X-Accepted-OAuth-Scopes: user
X-OAuth-Scopes lists the scopes your token has authorized.
X-Accepted-OAuth-Scopes lists the scopes that the action checks for.
So replace codertocat by the user of the repository you do not own, and check
X-Accepted-OAuth-Scopes to discover the expected scopes.
Compare them with X-OAuth-Scopes.

How do I curl against a git.io URL generated from a private repo?

I have a script that I'd like to be able to access via a curl command against its https://raw.githubusercontent.com/... location. Using git.io, it's really easy to shorten this URL to something like https://git.io/ABCDE.
But there's an issue related to the fact that my script exists in a private repository. If I directly curl against the githubusercontent URL, I get 404: Not Found. I'm able to bypass this by passing an authorization header with the request, e.g.
$ curl -H "Authorization: token <My Github Personal Access Token>" \
https://raw.githubusercontent.com/...
> !#/bin/bash
... # rest of script
However, when I use my shortened URL, I don't get anything back. Not even a 404.
$ curl -H "Authorization: token <My Github Personal Access Token>" \
https://git.io/ABCDE
$
Anyone know what's going on here?
The way a URL shortener works is that it issues some sort of 3xx-series HTTP status code that redirects you to the new location, and then you make your request against that new location. However, by default, curl does not follow redirects, so all you see when you make your request is the output from git.io, which in this case is nothing.
If you want to follow redirects, then you should use the -L option to curl, which will make it follow redirects. Note that this can be insecure in many cases when passing credentials, since any credentials passed with -H will be passed to any remote server that the data is redirected to. In this case, that's what you want, but it can be a security problem in other cases if the credentials were only intended for the original server.

Delete github respository via API

I want to delete a list of repositories using the github API. But I get the response:
{ "message": "Bad credentials", "documentation_url":
"https://developer.github.com/v3" }
Steps to reproduce
First I created a personal access token here: https://github.com/settings/tokens
I made sure it had the scope delete_repo
Then, create a variable for my token
export GITHUB_TOKEN=asasfsafaffafsafafsfs
Finally run this script:
#!/bin/bash
repos=(
"my_username/test-1"
)
for i in "${repos[#]}"
do
:
curl -XDELETE -H 'Authorization: token $GITHUB_TOKEN' "https://api.github.com/repos/$i ";
done
Changing the header to 'Authorization: $GITHUB_TOKEN' gives
{ "message": "Must have admin rights to Repository.",
"documentation_url":
"https://developer.github.com/v3/repos/#delete-a-repository" }
Searching the error and reading the provided link does not help me. How can I not have admin rights to my own repository (it's not in an org)? I have also tried checking everything in the personal access token generation page without effect.
Use the command (plugging in user, token, and repo)
curl -u $user:$token -XDELETE "https://api.github.com/repos/$user/$repo"
You must generate a token which includes the delete_repo scope through this page: https://github.com/settings/tokens/new

GitHub API Create File Returns 404

This seems to be answered elsewhere but using the same command as other answers I still get a 404.
I'm trying to test creating a file with GitHub's v3 API. Whether I use curl or a rest api tester I get a 404 "not found" error. I believe I am getting properly authorized as I can check my rate count and it is counting down from 5,000 (the rate limit you get when authorized).
I can do a GET like so:
curl -X GET -H "Authorization: token <mytoken>" https://api.github.com/repos/<myorg>/<myrepo>/contents/testfile
My PUT is like so:
curl -X PUT -H "Authorization: token <mytoken>" https://api.github.com/repos/<myorg>/<myrepo>/contents/newfile -d "{'message': 'Initial Commit','content': 'bXkgbmV3IGZpbGUgY29udGVudHM='}"
I've also tried this:
curl -X PUT -H "Authorization: token <mytoken>" https://api.github.com/repos/<myorg>/<myrepo>/contents/test.txt -d "{'path': 'test.txt', 'branch': 'dev', 'message': 'Initial Commit', 'committer': {'name': '<myname>', 'email': '<myemail>'}, 'content': 'bXkgbmV3IGZpbGUgY29udGVudHM='}"
So to recap, GET seems to work. PUT seems to not work. If anyone can help please do. If I get no answer, someone please tell my story.
Turns out, I'm just a moron. I was using the personal access token (PAT) of a user that had read-only access to my repo. Using a PAT of someone that had write access worked just fine. Who knew?
Sorry about that, internet. I'll never doubt you again.
I was creating an API wrapper and my input path had an extra leading "/" I removed the forward slash and no more error 404.
So, look for typos in the request URL, especially if your path constructor places a trailing slash. Good constructors usually take care of this case, but clearly not all.

Github v3 API - create a REPO

I’m trying to use the Github v3 API - I already implemented the required OAuth flow and it works well.
Now I’m trying some of the Repos API endpoints (http://developer.github.com/v3/repos/).
So far, I’m able to get a List of my repos using: GET /user/repos
However, when I try to create a repo using POST /user/repos, I get a 404.
Any thoughts what I might be doing wrong?

Can you please tell us how exactly you did the HTTP request? The 404 sounds like you were using a wrong path, probably. But to give a reliable answer instead a wild guess, we need to see your request, including how you are sending your token, just mask it with 'xxx' or something.
I'll show you in the meantime an example request, that is working:
curl -XPOST -H 'Authorization: token S3CR3T' https://api.github.com/user/repos -d '{"name":"my-new-repo","description":"my new repo description"}'
You would need to replace the OAuth token of course: S3CR3T
I had the same issue. The reason why you are getting a 404 with your oauth access token is that when you authorize to github you need to also additionally pass the scopes you want. For example, in the header you should see "X-OAuth-Scopes: repo, user", which means this user has read/write access to his profile and repositories. Once you have set the correct scopes you should be able to do POST/PUT requests just fine.
To see whether or not you have the correct permissions. You can do something like the following. Substitute the XXXXXXX with your access token.
curl -I https://api.github.com/user?access_token=XXXXXXXX
For creating repositories as a user you can use an personal access token and basic auth, which can be much simpler when you are fluffing around on the command line and have 2FA enabled.
curl -d '{"name":"test"}' -u githubuser:personaccesstoken https://api.github.com/user/repos
Create a personal access token here https://github.com/settings/tokens and make sure it has the 'repo' scope.
This script lets you read in in the token and project name as variables so you can use it in a script
#!/usr/bin/env bash -u
#
TOKEN=`cat token_file`
PROJECT=myproject
curl -X POST -H 'Content-Type: application/x-www-form-urlencoded' -d '{"name": "'"$PROJECT"'"}' https://api.github.com/user/repos?access_token=$TOKEN
