Address is an AWS ARN and includes api_client_id 'x' instead of 'y'

Technical Q&A
1

First off, I’m sorry about the formatting. Markdown apparently is not an option.

I’m running this request through Postman. Some posts to the Shopify developer forum (e.g., https://community.shopify.com/c/shopify-apis-and-sdks/eventbridge-integration-is-broken/m-p/878112#M56034) express without clear explanation that the request should be made within the Shopify app that would be subscribing to the Webhooks, but Postman seems to work, too.

In Postman . . .

Here’s the endpoint:

https://{{shopifyDevelopmentStoreName}}.myshopify.com/admin/api/2022-07/graphql.json

Here’s the GraphQL body:

mutation createWebhookSubscription(

$topic: WebhookSubscriptionTopic!, $webhookSubscription: EventBridgeWebhookSubscriptionInput!

) {
eventBridgeWebhookSubscriptionCreate(topic: $topic, webhookSubscription: $webhookSubscription) {
webhookSubscription {
id
}
userErrors {
message
}
}
}

Here’s the payload being sent (notice the “client_id_x” value within the arn property):

{
“topic”: “PRODUCTS_CREATE”,
“webhookSubscription”: {
“arn”: “arn:aws:events:us-east-1::event-source/aws.partner/shopify.com/client_id_x/LovecraftEventBridgeSource”,
“format”: “JSON”,
“includeFields”: “id”
}
}

Here’s the response I receive:

{
“data”: {
“eventBridgeWebhookSubscriptionCreate”: {
“webhookSubscription”: null,
“userErrors”: [
{
“message”: “Address is invalid”
},
{
“message”: “Address is an AWS ARN and includes api_client_id ‘client_id_x’ instead of ‘client_id_y’”
}
]
}

},
“extensions”: {
“cost”: {
“requestedQueryCost”: 10,
“actualQueryCost”: 10,
“throttleStatus”: {
“maximumAvailable”: 1000.0,
“currentlyAvailable”: 990,
“restoreRate”: 50.0
}
}
}
}

What’s entirely unclear is why Shopify is insisting upon validity of “client_id_y” when, in AWS, the value being displayed is undeniably ‘client_id_x’. Extremely confusing. I don’t even see what difference using the Shopify app would make except that it produces a client_id value that works counter to one’s expectations and intuitions.

Does anyone know why the heck Shopify isn’t just using the client_id value of the event bus created earlier in Amazon EventBridge?
