Duplicated webhooks when migrating to declarative webhooks

[nullndr]

I am trying to migrate the webhooks registration process inside my app to the new declarative webhooks method.

With my suprise, webhooks are being triggered twice, it does not look like the new method register the topic on Graphql, so there is it and the already existing webhook subscription registration on Graphql that trigger the same webhook.

Hi @nullndr, thank you for reporting this. This should be documented, but have you tried removing the webhook config code from the app? These two ways of configuring webhooks don't de-duplicate automatically.

Hi @nullndr I found where a warning for this is documented https://shopify.dev/docs/apps/build/webhooks/subscribe#app-specific-subscriptions

Basically, if you want to have overlap and not miss webhooks, you should allow for some duplicates in your code and delete the existing webhook subscriptions after having deployed the config changes.
