How to create repository in github through github API?

Go to Settings -> Developer Settings -> Personal Access Token Under OAuth Apps. Now, Generate a New Access token with Required privileges enabled. Ignore This if you already have one.

User Account:

Replace ACCESS_TOKEN with Token and NEW_REPO_NAME with your New Repository Name in the command below:

curl -H "Authorization: token ACCESS_TOKEN" --data '{"name":"NEW_REPO_NAME"}' https://api.github.com/user/repos

Organization:

curl -H "Authorization: token ACCESS_TOKEN" --data '{"name":"NEW_REPO_NAME"}' https://api.github.com/orgs/ORGANIZATION_NAME/repos

Step 1: Create a personal access token and use it in place of password

Step 2: On command line use the given API as a POST request

https://api.github.com/orgs/<organisation_name>/repos?access_token=<generated token>

or

https://api.github.com/user/<username>/repos?access_token=<generated token>

In body, pass this as a payload:

{
  "name": "<Repo Name>",
  "description": "<Some message>",
  "homepage": "https://github.com",
  "private": false,
}

You can pass other details.

There is a new solution official from cli.github.com. The other answers are deprecated.

First Install GitHub CLI. Run:

brew install gh

Then to create a repository with a specific name. Enter the following command:

gh repo create --private my-project

Here is the official documentation link to create a repo.

Based on the two above answers, here's a bash >=4.2 script to create a clone a repo.

#!/usr/bin/env bash
TOKEN=0000000000000000000000000000000000000000

if [[ $# < 3 ]]; then
    echo "arguments: $0 <RepoName> <RepoDescription>"
    exit 1
fi

REPO_NAME=$1; shift
REPO_DESCRIPTION="$@"

echo "Name: $REPO_NAME"
echo "Description: $REPO_DESCRIPTION"
echo "Calling GitHub to create repo"

read -r -d '' PAYLOAD <<EOP
