What AI APIs are Shopify devs using in apps/extensions?

Hey fellow Shopify devs!

I’m researching AI integrations for apps and extensions (theme/app blocks, UI extensions, etc.).

  • What AI APIs do you commonly use? (e.g., OpenAI/GPT, Anthropic/Claude, Google Gemini, Grok, or others?)

  • How do you integrate them? (Server-side calls in Node/Ruby apps? Webhooks? Storefront agents via MCP? Best practices for keys/security/performance?)

  • Any third-party platforms/tools that are super easy/dev-friendly? (e.g., pre-built apps like Tidio/Gorgias for chatbots, or no-code options?)

Bonus: With Shopify’s newer AI features (Sidekick, Catalog API, Storefront MCP), how are you combining them with external LLMs?

Really looking forward to hearing those ideas.

Thanks
