Shopify Cost Tuning

Overview

Optimize Shopify app and API costs through plan analysis, API usage monitoring, and strategies to minimize billable API calls. Covers Shopify store plans, Partner app billing, and API efficiency.

Prerequisites

Access to Shopify Partner Dashboard for app billing
Understanding of current API usage patterns
Knowledge of merchant's Shopify plan

Instructions

Step 1: Understand Shopify Plan Rate Limits

API rate limits are determined by the merchant's plan, not your app:

Merchant Plan	REST Bucket	REST Leak Rate	GraphQL Points	GraphQL Restore
Basic Shopify	40 requests	2/second	1,000 points	50/second
Shopify	40 requests	2/second	1,000 points	50/second
Advanced	40 requests	2/second	1,000 points	50/second
Shopify Plus	80 requests	4/second	2,000 points	100/second

Key insight: Upgrading from Basic to Advanced doesn't help rate limits. Only Plus doubles them.

Step 2: App Billing API

If your app charges merchants, use the GraphQL

appSubscriptionCreate

mutation to create recurring charges. Set

test: true

in development to avoid real billing.

See App Billing API for the complete mutation and variable setup.

Step 3: Monitor API Usage

Track GraphQL query costs and REST call counts over time to identify optimization opportunities. Log

extensions.cost.actualQueryCost

from every GraphQL response.

See Usage Tracker Class for a complete tracking implementation with reporting.

Step 4: Cost Reduction Strategies

Four key strategies: replace REST with GraphQL for targeted field selection, use bulk operations for exports, cache responses and invalidate via webhooks, and use Storefront API for public data.

See Cost Reduction Strategies for code examples of each approach.

Output

API usage monitored with cost tracking
Rate limit-efficient query patterns
App billing configured (if charging merchants)
Cost reduction strategies applied

Error Handling

Issue	Cause	Solution
Frequent throttling	High query cost	Reduce fields, use bulk ops
High hosting costs	Too many API calls	Cache responses, use webhooks
App billing rejection	Test mode not set	Use `test: true` in development
Merchant cancels	Unexpected charges	Clear billing in app onboarding

Examples

Quick Usage Check

// After every GraphQL call, log the cost
const response = await client.request(query);
const cost = response.extensions?.cost;
if (cost) {
  console.log(
    `Query cost: ${cost.actualQueryCost}/${cost.throttleStatus.maximumAvailable} ` +
    `(${cost.throttleStatus.currentlyAvailable} available)`
  );
}
