## Set up your integration

Find the right guide for your stack, scaffold the integration, and look up exactly which webhook events and fields Cello needs.

> *"I want to add user referrals to my app using Cello. Search the Cello docs for the integration guide and create a plan."*

## Verify it works

Run a health check across all four integration components (referral widget, attribution widget, signup tracking, and purchase tracking) and confirm Cello is receiving events. See [Integration Status](/guides/support/portal/integration-status) for what each component checks.

> *"Is my Cello integration working?"*

## Debug issues

Trace why rewards aren't triggering or signups aren't being attributed. The assistant inspects recent events and flags missing or malformed fields.

> *"Why aren't my Cello referral rewards being triggered?"*

## Optimize your program

Surface prioritized [best-practice recommendations](/guides/attribution/recommendations) across activation, sharing, and conversion.

> *"How can I improve my Cello referral program?"*
