Shopify API breaking changes (2024–2026): complete tracker and fixes

shopify 20 breaking / deprecation entries 2024–2026

Shopify ships API and SDK changes continuously. Most are additive — but the ones that are not can silently break integrations that worked yesterday. This page is the complete, continuously regenerated record of every Shopify breaking change and deprecation in the mendapi change database: 20 entries (16 breaking, 4 deprecation), each linked to its upstream source and, where possible, to a concrete fix.

How to read this page

Every entry carries a fixability verdict from the mendapi adjudication pipeline: code-fixable means a mechanical code change repairs the break (6 entries); not code-fixable means the change requires a business decision, credential provisioning, or upstream action that no codemod can produce (14 entries). Entries marked auto-fix pack have a deterministic, gold-tested migration pack that mendapi fix can apply locally.

Am I affected?

Reading a changelog tells you what changed — not whether your code uses the affected surface. The mendapi scanner answers that locally, in about 30 seconds, without any code leaving your machine:

npx mendapi sync
# -> one network call: pulls the change feed into a local database
npx mendapi scan
# -> N findings: file, line, provider, confidence
mendapi deps --match
# -> which of the changes below actually hit your endpoints

See Getting Started for the full workflow and the security model for why zero code upload is the default and only mode.

Automated migration packs for Shopify

mendapi ships 4 deterministic migration packs for Shopify — verified, idempotent codemods you can apply locally with mendapi fix. Full details in the pack catalog.

• shopify-customer-account-draftorder-price — Shopify Customer Account API: discountedUnitPrice -> approximateDiscountedUnitPrice (upstream reference)
• shopify-customer-last-incomplete-checkout — Shopify Customer Account API: remove Customer.lastIncompleteCheckout selections (Checkout subtree removed in 2026-10) (upstream reference)

• shopify-order-fulfillment-not-required — Shopify Admin API: handle new OrderDisplayFulfillmentStatus value FULFILLMENT_NOT_REQUIRED (2026-10) (upstream reference)

Recent Shopify releases adjudicated non-breaking

Not paging you is the other half of the job. The same pipeline that produced the timeline above also cleared 26 Shopify changes as additive or fix-only — releases an integrator can upgrade through without a migration. The most recent:

Measured: what a fixability verdict actually decides

Shopify does not publish a public OpenAPI spec repository, so unlike the Stripe or Twilio trackers this page carries no spec-diff corridor — the timeline is fed by changelog capture. What every entry does carry is an adjudicated fixability verdict with a machine-readable reason, and the split is the useful number: of the 20 breaking and deprecation entries above, 6 are code-fixable and 14 are not. Most of what breaks a Shopify integration cannot be repaired by a codemod, and knowing which is which before you triage is the point.

A verdict that says yes. “OrderDisplayFulfillmentStatus now returns FULFILLMENT_NOT_REQUIRED for orders with no items to fulfill” is code-fixable because the blast radius is enumerable: the fix is adding handling at exhaustive switch/comparison sites over OrderDisplayFulfillmentStatus — enumerable call-site fix.

A verdict that says no. “Card deposit endpoint now requires mTLS certificate” is not code-fixable — the endpoint and request shape are unchanged; what breaks is possession of a Shopify-issued client certificate, a credential-provisioning task only the operator can perform. A tool that pretended to patch that would be lying. Flagging it early, with the deadline attached, is the honest maximum — and that is what the scanner does.

Monitoring Shopify going forward

This page is regenerated from the change database, which is fed by release feeds, changelog capture and OpenAPI spec diffing — so it does not depend on Shopify writing a perfect changelog. mendapi monitors 84125 change records across 20 providers; hosted plans watch your repos continuously and open fix PRs when a change lands.
