Nest.Js w/ @nestjs-shopify/webhooks: 401 Invalid HMAC

[tictac232434]

Hey guy's,

I currently have the customers/create webhook handler in Nest.Js working through the shopify cli with

shopify webhook trigger --topic customers/create --api-version 2023-07 --client-secret ${secret} --delivery-method http --address http://localhost:4110/shopify-webhooks

This would work for my testing use case but it comes with a default user with default data bob@biller.com. Is there a way to change this to another users data?

Otherwise, on to my manual approach to use Insomnia to manually create the webhook request.

Here is my HMAC generation code

export function shopifyHMAC({ hmac, secret }: any): string {
  return crypto.createHmac('sha256', hmac).update(JSON.stringify(secret), 'utf-8').digest('base64');
}

Here is my Insomnia attempts with the headers shown in the Shopify Docs.

Any help or guidance would be greatly appreciated.

Respectfully,

Thomas

Hi Thomas,

Trying to understand this issue a bit more - are you always seeing bob@biller.com appearing when the webhook fires, or only when a test webhook fires?

I am seeing that for the test webhook. Is there a way to modify the payload for the test webhook? Or is there something I am missing for manually creating an HTTP payload through Insomnia?

For a test of the webhook - it will always be the default email address. You could run your own test by manually creating a "test" customer with the email you want, check the webhook, and then delete the test customer?
