App Platform: How to pass name of successful deployed app component and its commit hash to post-deploy job?

I’m running a MERN application with separate frontend and backend components on DigitalOcean App Platform. I’ve set up a post-deploy job to notify a Discord channel about successful and unsuccessful deployments using a shell script running in a Docker container that triggers a webhook.

This part is working fine - I receive the notifications. However, since my app consists of both frontend and backend components, I get two notifications per deploy attempt (because both components are deployed automatically right after each other).

What I Need Help With

I would like to pass information about which component triggered the post-deploy job, so my notifications can specify:

✅ “Backend deploy successful” or “Frontend deploy successful” instead of just “Deploy successful” (twice).

✨ Nice-to-have: Include the commit hash of the deployed component (frontend/backend) in the notification.

What I Tried

So far, I was able to retrieve the app URL, but regarding the commit hash, I only managed to get the commit hash of the post-deploy job itself, not the commit of the actual deployed component.

In my post-deploy job configuration, I defined the following environment variables:

jobs:
- dockerfile_path: dockerfile
  envs:
  - key: URL
    scope: RUN_AND_BUILD_TIME
    value: ${APP_URL}
  - key: COMMIT_HASH
    scope: RUN_AND_BUILD_TIME
    value: ${_self.COMMIT_HASH}

And I use them in the shell script like this:

URL=${URL}
COMMIT_HASH=${COMMIT_HASH}

What I Researched So Far

I’ve checked the following DigitalOcean documentation pages:

• Managing Jobs in App Platform

• Using Environment Variables in App Platform

However, I couldn’t find a clear way to pass the name of the app component triggering the post-deploy job or retrieve the commit hash of the deployed frontend/backend component instead of the post-deploy job’s commit hash.

Questions

1. How can I pass the name of the app component that triggered the post-deploy job?

2. How can I pass the commit hash of the deployed component (frontend/backend) instead of just the commit hash of the post-deploy job?

Thanks in advance for any insights! 🚀
