Build Shopify Functions — serverless WebAssembly extensions for discounts, delivery customization, payment customization, cart validation, cart transforms, and order routing. Use when extending Shopify's backend logic.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Shopify Functions (Serverless Wasm Extensions)

## Before writing code

**Fetch live docs**:
1. Fetch `https://shopify.dev/docs/apps/build/functions` for Functions overview
2. Web-search `site:shopify.dev shopify functions input output` for I/O schemas
3. Web-search `site:shopify.dev shopify functions api reference` for function types

## What Are Shopify Functions

Serverless extensions that run on Shopify's infrastructure:
- Written in JavaScript or Rust
- Compiled to **WebAssembly** (Wasm)
- Execute within Shopify's checkout and backend pipeline
- **11 million instruction limit** and **5ms execution time limit** — must be extremely fast
- No network access, no filesystem — pure computation on provided input
- Wasm binary size limit: 256 KB, input JSON size limit: 64 KB

## Function Types

| Type | Purpose | Example |
|------|---------|---------|
| **Discount** | Custom discount logic | Buy X get Y, tiered discounts |
| **Delivery customization** | Modify shipping options | Rename, reorder, hide methods |
| **Payment customization** | Modify payment methods | Hide, reorder, rename gateways |

How to install

The exact contents, by fingerprint

mdr add orcaqubits/agentic-commerce-skills-plugins/shopify-functions@sha256:f701103bec9ee184

The line at the top of this page pins the label git:20260914.08f85a3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
