Shopify Store Integration Not Working
Shopify integrations break in 2026 at three points: the OAuth installation flow (merchant cannot install the app or authorization fails), the API connection after installation (token permissions too narrow for the operations you are attempting), or the webhook pipeline (events are not being received or processed correctly).
Why This Happens
- Configuration gaps between tools or services
- Missing integrations or manual workarounds that weren't designed to scale
- Changes in vendor behavior, pricing, or API that weren't communicated clearly
What To Check First
- Verify your current setup matches the vendor's latest documentation
- Look for recent changes — platform updates, new team members, configuration drift
- Check if the problem is consistent or intermittent (different root causes, different fixes)
When To Escalate
- The problem is costing you money or customers per week
- You've spent more than 2 hours on it without progress
- A vendor quoted you more than $500 and you're not sure if it's necessary
Dealing with this right now?
For installation failures: check that your app's redirect URL in the Partner Dashboard exactly matches what you send in the OAuth request (including https vs http and trailing slashes). For permission failures after installation: the access token's permissions are set when the merchant installs — if you need additional scopes, the merchant must reinstall. Add a "permissions check" on app startup that calls the API with every required scope and surfaces permission errors early. For webhook issues: Shopify webhooks require verification — use `X-Shopify-Hmac-SHA256` header verification on every incoming request.
