FastSpring Platform Help

Step 1 — Gather context

If references/learnings.md exists, read it first for accumulated platform knowledge.

1. What are you trying to do?

   • A) Integrate the REST API (orders/subscriptions/products/accounts) or launch checkout
   • B) Build checkout — Store Builder Library (popup/embedded) or a hosted checkout session
   • C) Verify webhooks (X-FS-Signature HMAC-SHA256) and react to order/subscription events
   • D) Handle subscription lifecycle — dunning, overdue rebills, cancel/pause/resume
   • E) MoR concerns — tax/VAT remittance, refunds (fee is kept), payouts, chargebacks
   • F) Decide MoR (FastSpring) vs a raw processor, or compare to Paddle/Lemon Squeezy/Dodo

2. API or no-code? Code → REST API + SBL / webhooks. Low-code → hosted checkout + Zapier off webhooks.

Skip-ahead rule: if the user's prompt already provides enough context, skip to Step 2.

Step 2 — Route or answer directly
