How to populate render.yaml with deploy hook URL from another service?

Hi, I’m using render.yaml like so:

  - type: web
    env: static
  - type: cron
    name: Deploy
    schedule: "0 1 * * *"
    startCommand: "curl '???'"

To deploy my static site every day, my cron task needs the deploy hook URL from my static site. How do I populate this automatically, since it’s not known at the time I write the render.yaml?


Support replied to say this is not possible.
