What it does

Shopify Upgrade Migration is an agent skill from jeremylongshore/tons-of-skills-marketplace. Upgrade Shopify API versions and migrate from REST to GraphQL with breaking change detection. Use when upgrading API versions, migrating from deprecated REST endpoints, or handling Shopify's quarterly API release cycle. Trigger with phrases like "upgrade shopify", "shopify API version", "shopify breaking changes", "migrate REST to GraphQL", "shopify deprecation".

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/product-input-split.md` and `references/rest-to-graphql-migration.md`). Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering GraphQL, REST APIs and Anomaly detection. It works with Shopify and GraphQL. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Upgrading API versions
  • Migrating from deprecated REST endpoints
  • Handling Shopifys quarterly API release cycle
  • With phrases like upgrade shopify

Example prompts

  • “s quarterly API release cycle. Trigger with phrases like”
  • “shopify API version”
  • “shopify breaking changes”
  • “/shopify-upgrade-migration”

Requirements

  • A credential in SHOPIFY_API_KEY
  • A credential in SHOPIFY_API_SECRET
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(npm:*), Bash(curl:*)

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Check Current Version and Available Versions
  2. Review Breaking Changes
  3. Migrate REST to GraphQL
  4. Update API Version in Config
  5. Handle the ProductInput Split (2024-10)

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash(npm:*)
    • Bash(curl:*)

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • jq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • shopify.dev

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SHOPIFY_API_KEY
    • SHOPIFY_API_SECRET

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Shopify Upgrade Migration loads about 1.3k tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 98 tokens; SKILL.md has 315 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~98
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.8k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Shopify Upgrade & Migration

Overview

Guide for upgrading Shopify API versions (quarterly releases) and migrating from the legacy REST Admin API to the GraphQL Admin API. REST was deprecated as a legacy API on October 1, 2024.

Prerequisites

  • Current Shopify API version identified
  • Git for version control
  • Test suite available
  • Access to Shopify release notes

Instructions

Step 1: Check Current Version and Available Versions
bash
# Check what API version you're using in code
grep -r "apiVersion" src/ --include="*.ts" --include="*.js"
grep -r "api_version" . --include="*.toml"

# Check what versions the store supports
curl -s -H "X-Shopify-Access-Token: $TOKEN" \
  "https://$STORE/admin/api/versions.json" \
  | jq '.supported_versions[] | {handle, display_name, supported, latest}'

Shopify releases quarterly (e.g., 2025-01, 2025-04, 2025-07, 2025-10). Versions are supported for ~12 months after release.

Step 2: Review Breaking Changes

Key breaking changes by version:

VersionBreaking ChangeMigration
2024-10ProductInput split into ProductCreateInput + ProductUpdateInputUpdate mutations to use separate types
2024-10REST declared legacyMigrate to GraphQL Admin API
2024-07InventoryItem.unitCost removedUse InventoryItem.unitCost on InventoryLevel
2024-04Cart warnings replace inventory userErrors (Storefront)Update cart error handling
2025-01New public apps must use GraphQL onlyNo REST for new public apps
Step 3: Migrate REST to GraphQL

Side-by-side comparison of REST vs GraphQL patterns, plus a mapping table for common endpoints (products, orders, customers, webhooks).

See REST to GraphQL Migration for the complete examples and mapping table.

Step 4: Update API Version in Config
typescript
// src/shopify.ts — use LATEST_API_VERSION instead of hardcoded dates
import { LATEST_API_VERSION } from "@shopify/shopify-api";

const shopify = shopifyApi({
  apiKey: process.env.SHOPIFY_API_KEY!,
  apiSecretKey: process.env.SHOPIFY_API_SECRET!,
  hostName: process.env.SHOPIFY_HOST_NAME!,
  apiVersion: LATEST_API_VERSION,
  // ...
});
toml
# shopify.app.toml
[webhooks]
api_version = "2025-04"  # Update quarterly
Step 5: Handle the ProductInput Split (2024-10)

In API version 2024-10, Shopify split the single ProductInput type into ProductCreateInput and ProductUpdateInput. All product mutations need updating.

See ProductInput Split for before/after examples.

Output

  • API version updated across all config files
  • REST endpoints migrated to GraphQL equivalents
  • Breaking changes addressed
  • Test suite passing on new version

Error Handling

ErrorCauseSolution
API version unsupportedVersion too oldCheck supported versions endpoint
Field not found in typeField renamed/removed in new versionCheck release notes for migration
ProductInput is not definedUsing old type on 2024-10+Use ProductCreateInput / ProductUpdateInput
REST API 410 GoneEndpoint removedMigrate to GraphQL equivalent

Examples

API Version Upgrade Script
bash
#!/bin/bash
OLD_VERSION="2024-10"
NEW_VERSION="2025-04"

echo "Upgrading Shopify API from $OLD_VERSION to $NEW_VERSION"

# Find all files referencing old version
echo "Files to update:"
grep -rn "$OLD_VERSION" . --include="*.ts" --include="*.js" --include="*.toml" --include="*.json"

# Replace (review diff before committing)
find . -type f \( -name "*.ts" -o -name "*.js" -o -name "*.toml" \) \
  -exec sed -i "s/$OLD_VERSION/$NEW_VERSION/g" {} +

echo "Updated. Run tests: npm test"
Deprecation Monitor
typescript
// Log deprecation warnings from Shopify response headers
function checkDeprecationHeaders(headers: Headers): void {
  const sunset = headers.get("x-shopify-api-deprecated-reason");
  if (sunset) {
    console.warn(`[SHOPIFY DEPRECATION] ${sunset}`);
    // Alert your team
  }
}
