A guide to maintaining Shopify's older REST Admin API, which lets software read and change store data through web requests. New public apps are expected to use GraphQL instead.

Use it for legacy apps, archived read-only systems, temporary compatibility layers, and planning a migration from REST to GraphQL.

It helps developers support older integrations while understanding when they need to move to Shopify's current API.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.03031
Opus 5	$0.00026	$0.01515
Sonnet 5	$0.00011	$0.00606
Haiku 4.5	$0.00005	$0.00303

Security

Grade B, and why

admin-rest scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

const response = await fetch( 'https://store.myshopify.com/admin/api/2026-01/graphql.json', { method: 'POST',

Not a fault in itself. Listed so you know the mod talks to something, and to what.

When to Use REST API (Rarely)

LEGACY API WARNING: Shopify has classified the REST Admin API as legacy since October 1, 2024. Since April 1, 2025, new public apps must use the GraphQL Admin API exclusively. Shopify has not published a blanket December 2026 shutdown date for every REST resource.

Use REST API ONLY for:

Maintaining existing legacy applications built before 2024
Simple read-only queries from archived systems
Temporary compatibility layers during GraphQL migration
Systems that cannot be updated to use GraphQL

MIGRATE TO GRAPHQL FOR: All new features, bulk operations, cost efficiency, and latest Shopify functionality.

REST vs GraphQL Comparison

Feature	REST (Legacy)	GraphQL (Current)
Rate Limiting	40-request standard bucket, restored at 2 requests/sec	Cost-based; restore rate varies by plan
Pagination	Limit/offset (inefficient)	Cursor-based (Relay)
Field Selection	Fixed response (bloated)	Precise fields only
Bulk Operations	Sequential requests	Native JSONL bulk
Latest Features	Some newer features are GraphQL-only	Current platform features
Support Window	Versioned; verify the selected version and resource	Versioned; verify the selected version
Status	Maintenance only	Production active

API Endpoint Structure

Base URL: https://{shop}.myshopify.com/admin/api/2025-10/

Authentication (Header):

curl -X GET "https://store.myshopify.com/admin/api/2025-10/products.json" \
  -H "X-Shopify-Access-Token: {access_token}"

The examples below use 2025-10 for compatibility with older integrations. Before deploying, select a currently supported API version from Shopify's version schedule and test the exact resources you use.

Rate Limiting

REST limits:

Standard limit: a 40-request bucket per app and store
Standard restore rate: 2 requests per second
Shopify Plus: limits are typically 10 times the standard limit
Read X-Shopify-Shop-Api-Call-Limit and honor Retry-After; Shopify can reduce limits temporarily

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

It adds 53 tokens to every session and 3,031 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
