To create a webhook with topic VARIANTS_OUT_OF_STOCK I use GraphQL https://shopify.dev/api/admin-graphql/2022-01/enums/WebhookSubscriptionTopic#value-variantsoutofstoc...
"The webhook topic for variants/out_of_stock events. Occurs whenever a variant becomes out of stock. Requires the read_products scope."
So, I use https://shopify.dev/api/admin-graphql/2021-10/mutations/webhookSubscriptionCreate
mutation {
webhookSubscriptionCreate(
topic: VARIANTS_OUT_OF_STOCK
webhookSubscription: {
callbackUrl: "https://server/path"
format: JSON
})
{
webhookSubscription {
id
}
userErrors {
message
}
}
}
It works fine in the GraphiQL app, but not in my own app.
This is what I do:
- Install GraphiQL app, only grant products_read (as this is the access scope needed). Creating this webhook via the GraphiQL app works. I am aware of app scope. This is just for in the GraphiQL app.
- Install my own app, grant products_read and a few more. Check via a GraphQL query that indeed there are zero webhooks (fresh app install on test shop). Then, creating this webhook from my own app's code using the GraphQL mutation listed above gives the response displayed below.
- To be clear: creating a PRODUCTS_UPDATE webhook from my app using the GraphQL API works fine. This issue seems to be specific to topic: VARIANTS_OUT_OF_STOCK
- is there another scope besides read_products that is needed? Documentation states read_products scope is needed only. I tried all other scopes available, still the same message.
- edit:just to be clear, my app uses both an offline token (for cron job related calls) as well as online token (dashboard-based user interaction). In this example, I use the offline token.
