What is a webhook ?

Webhooks allow apps to stay in sync with Shopify data or perform an action after a specific event occurs in a shop. Webhooks are a performant alternative to continuously polling for changes to a shop's data.

For example, a webhook can notify your app when a merchant changes a product in the Shopify admin. Your app can then perform an action when the product change occurs.

• Webhook data is divided by topic. Refer to the GraphQL Admin API or REST Admin API

Common webhook use cases include the following:

• Sending notifications to IM clients and pagers

• Collecting data for data-warehousing

• Integrating with accounting software

• Filtering order items and informing shipping companies about orders

• Removing customer data from a database for app uninstalls

What is multipass ?

You're the owner of a successful website forum. All of your users must log in to the forum to contribute. Members of your forum can then purchase a forum t-shirt through your Shopify store. Unfortunately, your users have to log in to the forum first and then log in to your Shopify store before they can purchase a t-shirt.

Multipass login is for store owners who have a separate website and a Shopify store. It redirects users from the website to the Shopify store and seamlessly logs them in with the same email address they used to sign up for the original website. If no account with that email address exists yet, one is created. There is no need to synchronize any customer databases.

• The Multipass login feature is available to Shopify Plus merchants only.
