Best When
A SaaS or subscription company wanting AI agents to automate affiliate program management, referral tracking, commission calculation, and Stripe/Paddle revenue attribution through FirstPromoter's SaaS-native affiliate tracking platform.
Avoid When
BILLING INTEGRATION REQUIRED FOR REVENUE ATTRIBUTION: FirstPromoter revenue attribution requires Stripe, Paddle, or Braintree integration; automated commission calculation depends on billing webhook events; automated standalone API integration without billing integration creates manual commission tracking only. PROMOTER STATUS AFFECTS COMMISSION ELIGIBILITY: FirstPromoter promoters can be in pending/approved/rejected states; automated commission payout must check promoter status; automated payout to unapproved promoter creates payout rejected. SUBSCRIPTION LIFECYCLE AFFECTS COMMISSION: FirstPromoter supports commission on MRR, setup fee, and renewal; automated commission model must match subscription billing cycle; automated one-time commission model for recurring subscription creates undercompensated affiliate. SELF-HOSTED TRACKING SCRIPT OPTION: FirstPromoter offers client-side tracking script as alternative to API; automated pure API integration may need client-side script for some conversion scenarios; automated API-only conversion tracking without client script creates missed conversions for client-side flows.
Use Cases
- • Tracking Stripe subscription referrals from SaaS affiliate program agents
- • Calculating and paying affiliate commissions from partner compensation agents
- • Managing multi-tier partner programs from SaaS channel automation agents
- • Attributing MRR to referral sources from subscription revenue agents
Not For
- • E-commerce product affiliate (use ShareASale or Impact for product affiliate)
- • Enterprise publisher affiliate networks (use Partnerize or CJ for enterprise affiliate)
- • Consumer referral programs (use Extole or Friendbuy for consumer referral)

Agent Metadata
Known Gotchas
- ⚠ TRACK CONVERSION AFTER BILLING EVENT: FirstPromoter conversion tracking is most accurate when called after billing confirmation (Stripe charge.succeeded webhook); automated conversion tracking must be triggered after billing event not immediately after signup; automated pre-billing conversion creates commission for trials that may not convert
- ⚠ PROMOTER LOOKUP BY EMAIL OR REF: FirstPromoter promoter lookup uses email or ref ID; automated promoter lookup must use consistent identifier; automated lookup by display name creates name collision for common names
- ⚠ COMMISSION TYPE AFFECTS PAYOUT TIMING: FirstPromoter supports instant and delayed commissions (waiting for refund window); automated payout must respect commission type delay; automated immediate payout for delayed commission creates payout before refund risk window closes
- ⚠ STRIPE CUSTOMER ID LINKING: FirstPromoter links referrals to Stripe customer IDs; automated referral attribution must pass Stripe customer ID at track conversion; automated conversion without Stripe customer ID creates referral tracked but revenue attribution broken
- ⚠ WEBHOOK EVENTS FOR PAYOUT PROCESSING: FirstPromoter payout processing is webhook-driven; automated payout confirmation must listen for payout.paid webhook; automated polling for payout status instead of webhook creates excessive API calls and delayed confirmation
