The v2 of the App Bridge was released yesterday: https://shopify.dev/tutorials/migrate-your-app-to-app-bridge-2 However, the documentation claims that a host parameter will be passed as part of the query string in the request back to my API during the OAuth handshake. The issue is that this is no…

On our end it still remains too.

Hi everyone, thank you for your patience and being one of the first to jump into upgrading. Really appreciate the fast reporting of this issue. The fix for the missing host search param during auth is in and it’s currently being rolled out. Some apps should start seeing it today, and more in the ne…

Hi Hanna, Suddenly, stores are unable to install our app as the signature check is failing, despite no changes on our end. Please could you explain what’s been updated exactly? Thanks

Possibly unrelated. Working normally now…

What does host mean in the query? hostname of the App / hostname of the store?

host url parameter is the hostname of the store, used by the App Bridge 2.0 client. It’s a different version of shop as described in the Get and store the shop origin guide.

Hello, do I understand correctly that the host parameter is added to the whole OAuth process? Because in our app we’re not using App Bridge or Embedded Apps but the installation is not working because of the failing hmac verification.

Hi @AurimasR Double check that you are including all parameters, other then the hmac param itself, when you create your hmac to compare to Shopify’s. I think it mentions on the documentation somewhere that parameters are subject to change, so remove the hmac param and include all else. Thanks

@BoxUp We were dependent on the exact parameters. But you are right, I see it is mentioned in the documentation that parameters are subject to change. Thanks!

Thanks for the followup, I don’t believe changes were made to shop, host was added on top of shop. Glad to hear that it’s working properly now.
