  • new key in the backoffice: appStoreInstallRedirectUri (for example https://www.appmixer.com/connectors/shopify)
  • new plugin route https://api.qa.appmixer.com/plugins/appmixer/shopify/install. Shopify calls this url with the shop query param. This params identifies the shopify instance to install the Appmixer app. The install route creates the OAuht link for the shop and redirects to the auth url. This will trigger installation app install process.

  HOW TO TEST

  • got to https://api.qa.appmixer.com/plugins/appmixer/shopify/install?shop= Where you shop instance is for example appmixer.myshopify.com
  • app installation screen should show up
  • install the appmixer app
  • go to the https://admin.shopify.com/store/appmixer/settings/apps?tab=installed and check the Appmixer app is installed
