Pageview

Call on each view you care about. First referrer, landing page, and UTM are attached from the first visit. Last referrer and last UTM are sent from the current page.

cashline('pageview');

Goal

Fire after a real signup (or any named action). The default funnel treats signup as step two. See goals and funnels.

cashline('goal', { name: 'signup' });

Purchase

Fire after your store confirms an order. Amount is in major units (rand, not cents).

cashline('purchase', {
  amount: 199,
  currency: 'ZAR',
  reference: 'ORD-1042'
});

Paystack metadata

A South African SaaS should put visitor_id on Paystack initialize. Full walkthrough: Paystack visitor_id. Peach and Yoco are text notes only.

What is stored

• visitor_id — first-party, cookieless, reused across sessions
• session_id — one tab session
• first_referrer, landing_page, first UTM
• last_referrer, last UTM — current hit

Billing

Subscriptions use Paystack TEST. Starter is R149 (PLN_su9arwmqh854pjm), Growth is R299 (PLN_eizhuzd8dckw0pm). The server initializes with email + plan + attribution metadata, then verifies the reference. Configure the webhook to /api/paystack/webhook for charge.success, subscription.create, invoice.payment_failed, and subscription.disable.
