Shopify Amazon EventBridge - validate the HMAC digest of each request

I have created the Public app and I have integrated all required Webhooks using the Shopify <> Amazon Event bridge:https://shopify.dev/apps/webhooks/configuration/eventbridge.

In the Define pattern section, I did choose the Event pattern and select the Pre-defined pattern by service Shopify. Screenshot:

When I submitted my public app to Shopify. I did get rejection & received the following reply from Shopify.

App must verify the authenticity of the request from Shopify.> Your app’s HTTPS webhook endpoints must validate the HMAC digest of each request, and return an HTTP 401 (Unauthorized) response when rejecting a request that has an invalid digest. Learn more about verifying a webhook

I have the following questions :

Do we need to validate the webhook request using HMAC with EventBridge? If yes how can I do that?

As mentioned in the community link: “Shopify is able to produce events into the partner event source. There is no need to validate HMAC with EventBridge.”

There is no need to validate HMAC with EventBridge, but you should HMAC validate your mandatory webhooks because you can’t process them with EventBridge, only with HTTPS endpoints for the moment.
