API integration — If you want to automatically add referrers or qualify leads by connecting Referral Factory directly to your own backend system, your developer would use the REST API.
Webhook setup — If your qualification trigger lives in a custom system (not HubSpot, Stripe, Salesforce, etc.), a developer can configure your system to send a webhook to Referral Factory when a customer converts.
Custom HTML pages — Enterprise plan users can upload their own fully custom-designed referral pages. Building those pages requires design and development work.
Installing the website widget or pop-up — This requires pasting a small snippet of code into your website. Most non-developers can do this, but if your website is managed by an agency or locked CMS, you may need their help.
