Triggering amplify hosting build using github actions

[HardikGaur]

I wanted to trigger amplify hosting builds for my nextjs website using github actions. I searched for user triggered build and came to this issue which mentions using webhooks to do this.
Hi @dmudro that is correct, resolving this one for now, let us know if you have any issues getting that going

Can we use github actions to trigger builds?

Yes, you can use manual webhooks to trigger builds -> https://docs.aws.amazon.com/amplify/latest/userguide/webhooks.html
