Why Indexiz

Why Indexiz for Shopify Integrations

We have connected Shopify to dozens of back-office systems and we know where syncs break: rate limits, partial failures, duplicate orders and API version changes. Our integrations are built to handle all of them.

Resilient by Default

Queues, retries, idempotency keys and alerting so a failed call never becomes a lost order.

API-First Engineering

GraphQL Admin API, webhooks and Shopify Functions used the way Shopify intends, ready for each API version.

Visibility for Your Team

Sync dashboards and logs so operations staff can see what moved and fix exceptions themselves.

Shopify Partners

A dedicated Shopify team that also handles theme, Plus and migration work when you need it.

Our approach

Map the Data Before Writing Code.

We document every field, owner and direction of travel between Shopify and your systems, agree the rules, then build and test with real orders.

Every job is queued with retries and idempotency. Failures are logged, retried and surfaced on a dashboard with alerts so nothing silently disappears.
