Common questions

If something isn't covered here, ping contact@growthrail.dev — early-access teams get direct Slack access to engineering.

Which platforms do you support?
Web (vanilla JS in any framework), React 16.8+, and React Native 0.60+ (Expo 54). The core SDK is isomorphic, so it runs in Node, browsers, and React Native. For everything outside JS, the REST API integrates with any backend in any language.
Do I have to build the share UI myself?
No. The SDK ships a modal, a drawer, an inline panel, a floating trigger button, and a new-user banner. Theme color, position, copy, and light/dark are configured from the dashboard. You can also keep the headless API and render your own UI.
What about fraud and double-claiming?
Per-project allow- and block-lists, single-claim enforcement on each LinkClickAnalytics ID, soft-deletes on every entity for audit trails, and security-logged authentication. Webhook secrets are per-webhook so a leak is contained.
How do rewards get delivered?
When a referred user completes a reward event, GrowthRail fires referral.converted to every enabled webhook on the campaign. You handle the actual reward in your stack — Stripe credit, in-app entitlement, payout, whatever. We retry up to 5× with backoff and log every attempt; you can manually replay from the dashboard.
Is there a hosted dashboard or do I build my own?
Yes, GrowthRail provides a fully hosted dashboard where you can manage campaigns, users, webhooks, and analytics from a single console.
Can I run multiple referral programs?
Yes. Each project is an independent program with its own campaign config, webhooks, app users, and API keys. Great for separate apps in the same org, or buyer vs. seller programs in a marketplace.
How much does GrowthRail cost?
The Developer plan includes up to 50 successful referrals per month at no cost. Business adds unlimited referrals; current monthly and annual prices are shown live from Stripe on the pricing page.
