App Events auth returns application_cannot_be_found for valid Dev Dashboard Client ID

Shopify App Store
1

Hi,

I’m trying to authenticate a development app against the Shopify App Events API, but the token endpoint returns application_cannot_be_found.

App:
PROVEN Catalog Remediator

App GID:
gid://shopify/App/418194522113

Client ID:
ec7129ba1a17b13e5a02d9054bf006d1

Endpoint:
POST https://api.shopify.com/auth/access_token

Request:
grant_type=client_credentials
client_id=
client_secret=

Response:
HTTP 400

error:
application_cannot_be_found

error_description:
Could not find Shopify API application with client_id “ec7129ba1a17b13e5a02d9054bf006d1”.

Request ID:
c9212588-8bd7-4515-a70e-317ce37269be-1789307600

I have verified the application identity independently:

  • The Client ID shown in Shopify Dev Dashboard is exactly:
    ec7129ba1a17b13e5a02d9054bf006d1
  • Shopify Partner API returns the same apiKey for:
    gid://shopify/App/418194522113
  • The Partner API app name is PROVEN Catalog Remediator.
  • The application is installed on a development store.
  • The app is not yet published in the Shopify App Store.
  • Partner API access and subscription reads for this same application are working correctly.

So the Dev Dashboard Client ID, Partner API App GID and Partner API apiKey all match, but the App Events authentication endpoint reports that the application cannot be found.

Is App Events authentication expected to work for an unpublished development app?

If yes, could Shopify staff check whether this application has been provisioned correctly for App Events, using the Request ID above?

Thank you.

Hi,

This issue is now resolved on my side and App Events authentication is working correctly for the application.

No further investigation is needed for the Request ID above.

I’m marking the thread as resolved.

Thank you.
