GitHub Actions

Add a final step that pings your monitor only when the previous steps succeeded.

Scheduled workflow

For a workflow that runs on a schedule, add a ping step at the end of the job:

name: Nightly job
on:
  schedule:
    - cron: "0 3 * * *"

jobs:
  run:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Do the work
        run: ./scripts/nightly.sh

      - name: Ping Did My Job Run
        run: curl -fsS https://api.didmyjobrun.com/ping/${{ secrets.DMJR_PING_KEY }}

• By default a step only runs if all previous steps succeeded, so if Do the work fails, the ping step is skipped and you get alerted.
• Store your ping key as a repository secret (here DMJR_PING_KEY) rather than hardcoding it. Copy the key from your monitor on the dashboard.

Make the success condition explicit

The implicit behaviour above is enough, but if you want the intent spelled out, add if: success() to the ping step. It runs only when every earlier step succeeded — a failed run skips the ping and you get alerted:

      - name: Ping on success only
        if: success()
        run: curl -fsS https://api.didmyjobrun.com/ping/${{ secrets.DMJR_PING_KEY }}

Keep the monitor’s period at your schedule interval (1 day here) plus some grace, since GitHub’s scheduled runs can start a few minutes late.
