Hi again,

I’m trying to register an app in ShopWare (dockware installation) and after creating manifest file I’m trying to install it via console by `bin/console app:install --activate MyApp` however I’m receiving response that is not telling me too much:

` [Shopware\Core\Framework\App\Exception\AppRegistrationException] The app provided an invalid response`

Request going from shopware to my app has those params:

`{"shop-id"=>"UzdrLOQrFbUcZP5e", "shop-url"=>"http://localhost", "timestamp"=>"1661350836"}`

and I’m sending back this response (in json):

`{"proof"=>"62e96ed5dcac5f816196494f0d37b935bf4a0cd6799b0fb16c7729a1f538aac4", "secret"=>"randomly_generated_secret", "confirmation_url"=>"http://host.docker.internal:3000/confirmation"}`

Am I calculating it correctly (digest is calculated as sha256 from shop-id, shop-url, app-name and app-secret) ? Or what could I do wrong here? Logs do not contain anything valuable.

Again - topic could be closed. Problem was with calculating proof as sha256 and not hmac sha256 - now it works 🙂
