Hi folks in this blog we will see how we can Trigger a GitHub action with a HTTP Request using curl command.This is very quick and simple so let’s see how we can Trigger a GitHub action in few easy steps..

First lets see what is curl.


Curl stands for client URL. It is a command-line tool that we can easily use to transfer data to and from a server. It let’s us talk to a server by specifying We will use curl to send API requests.

For successfully triggering a github action we have to perform three main steps.These three steps are given below.

  • Create github action.
  • Generate a personal access token.
  • Create a http request.

Step first:

You can use the GitHub API to trigger a webhook event called repository_dispatch when you want to trigger a workflow for activity that happens outside of GitHub.We are triggering the github action outside the github so we must create with repository_dispatch event.

Now first create a new Github action with repository_dispatch event.This is the same event used when triggering the action through the UI.I have created a .yml file you can see here.

name: Do Something That Needs Scheduled

    types: do-something
    name: Run Some Thing
    runs-on: ubuntu-latest
      - name: Do Something
        run: echo Doing Something...

Step Second:

For triggering a github action through curl command you need a personal access token to use the Github API.So make sure you have a personal access token if not you can create a new one by using following link.

You can create one here: sure you add repo and workflow permissions.

Step Third:

To trigger the custom repository_dispatch webhook event you must send a POST request to a GitHub API endpoint.

And provide an event_type name to describe the activity type.

To trigger a workflow run ,also configured your workflow to use the repository_dispatch event as I have already defined.

curl -H "Accept: application/vnd.github.everest-preview+json" \
    -H "Authorization: token <your personal access token>" \
    --request POST \
    --data '{"event_type": "do-something"}' \<username>/<repo>/dispatches

Perform above command on your terminal and if you want to check that the GitHub action is trigger or not you can check from following command.

curl -H "Accept: application/vnd.github.everest-preview+json" \
    -H "Authorization: token <your personal access token>" \
  --request GET   \
  --data '{"event_type": "do-something"}' \<username>/<repo>/actions/runs



In this blog we have seen how in few easy steps we can trigger a github action job remotely via curl.If you have any query tell me in comment section and also share this blog to your friends.Thank You.
