FAQPage Schema
How do I build a Shopify app with Remix that handles OAuth and session storage?▼

To build a Shopify app with Remix, you initialize a project using the Shopify CLI, implement OAuth for authentication, and use Prisma for persistent session storage to manage user sessions across embedded app workflows.

What's the best way to add a checkout UI extension to a Shopify Remix app?▼

Adding a checkout UI extension to a Shopify Remix app involves configuring extension targets like the thank-you page, allowing you to access app metafields and render custom components directly within the Shopify checkout flow.

How do I handle mandatory GDPR webhook endpoints in my Shopify application?▼

Handling GDPR webhook endpoints in a Shopify application requires setting up specific webhook subscribers for customer data requests and redaction, verifying HMAC signatures, and ensuring your server responds correctly to maintain app store compliance.

Can I use Admin GraphQL API queries and mutations to manage product data in Shopify?▼

You can use the Shopify Admin GraphQL API to execute queries and mutations for managing product data, handling metafield-based settings storage, and managing error or rate-limit handling directly within your Remix application logic.

How do I verify webhook HMAC signatures for a Shopify app?▼

Verifying webhook HMAC signatures for a Shopify app involves checking the request headers against the app secret, ensuring the payload is authentic, and processing GDPR and operational webhooks securely without exposing sensitive data.

Does Shopify CLI support tunneled development servers for testing checkout extensions locally?▼

Shopify CLI supports running a tunneled development server for testing checkout extensions locally, enabling rapid iteration on extension targets, Polaris UI components, and OAuth callbacks before deploying to production.
