SamCart Platform Help
SamCart is a hosted checkout/cart platform for digital-product creators: conversion-optimized checkout pages with order bumps, 1-click upsells, subscription billing with dunning ("Subscription Saver"), and a built-in Affiliate Center — subscription-priced (vs ThriveCart's lifetime license). Automation runs through a read-mostly REST API plus "Notify URL" webhooks.
Step 1 — Gather context
If references/learnings.md exists, read it first for accumulated platform knowledge.
Ask only what you can't infer from the user's prompt:
-
What are you trying to do?
- A) Integrate SamCart data (orders/subscriptions/customers) with a CRM, warehouse, or your app
- B) Set up or debug Notify URL webhooks
- C) Manage subscriptions programmatically (cancel, schedule-cancel, dunning visibility)
- D) Decide on a plan (Core vs Pro vs Enterprise) or understand fees
- E) Checkout/upsell/affiliate configuration questions -
Do you have an API key yet? The API is a support-gated private beta — keys come from support@samcart.com, not self-serve settings.
Skip-ahead rule: if the user's prompt already has enough context, go straight to Step 2.
Step 2 — Route or answer directly
| If the user's question is about… | Route to |
|---|---|
| Which cart/checkout platform to pick (SamCart vs ThriveCart/Checkout Page/Gumroad) | /sales-checkout {question} |
| Checkout-conversion strategy (bump/upsell design, cart abandonment) across tools | /sales-checkout {question} |
| Digital-product pricing, validation, launch strategy | /sales-digital-products {question} |
| Migrating active subscriptions between billing platforms without double-billing | /sales-subscription-billing {question} |
| Running an affiliate program (commission design, recruiting) | /sales-affiliate-program {question} |
When routing, give the exact command: "This is a {domain} question — run: /sales-checkout {original question}"
Otherwise, answer SamCart-specific questions directly using Step 3.
Step 3 — SamCart platform reference
Read references/platform-guide.md for the full reference — capabilities & automation surface, pricing/plan gates, data model (orders → cart_items → charges/subscriptions), and quick-start recipes (nightly order sync, verified webhook listener, subscription cancellation).
For raw endpoint detail, auth, pagination, webhook triggers, and payload shapes, read references/samcart-api-reference.md.
Answer using only the relevant section — don't dump the full reference.
Step 4 — Actionable guidance
- Treat webhooks as hints, the API as truth. Notify URL payloads are unsigned — verify by re-fetching the order/subscription with your
sc-apikey before granting access or moving money. - The API reads; the UI writes. You can pull orders/charges/customers/subscriptions and refund/cancel — but products, pages, bumps, and upsells are configured only in the UI (or via Zapier/Make actions).
- Build self-serve cancellation on
scheduleCancel. Billing-after-cancellation is SamCart's loudest public complaint — a logged, API-driven cancel path plus theSubscription Canceledwebhook protects both you and your buyers. - Model Pro-gating before committing. Order bumps, upsells, A/B testing, and the Affiliate Center — the features SamCart markets — need Pro ($199/mo). Always present plan pricing as best-effort and tell the user to verify current numbers at samcart.com/pricing — SamCart has restructured plans before.
If you discover a gotcha or tip not in references/learnings.md, append it there with today's date.
Gotchas
Best-effort from research (2026-07) — review these, especially plan pricing and beta-API status that may have changed.
- API access is a support-gated private beta — email support@samcart.com and plan for approval lead time; there's no self-serve key page. Keys go in the
sc-apiheader (notAuthorization). - Webhooks are unsigned with no documented retries — use an unguessable endpoint token + API verification, and keep a polling reconciliation; the Integration Engine only logs the last 1,000 events.
- Recurring revenue doesn't port off SamCart — payment tokens stay behind when you leave, so subscribers must re-consent on the next platform. Weigh this before building a large subscription base here (see
/sales-subscription-billing). - Conversion features are Pro-gated — Core ($79/mo) excludes order bumps, 1-click upsells, A/B testing, and the Affiliate Center; those need Pro ($199/mo). Legacy Launch/Grow/Scale plans reportedly scaled with revenue.
- Cancellation/billing disputes are the #1 public complaint (including Creator U trials converting into paid SamCart accounts) — as a seller, keep your own cancellation logs; as a buyer of SamCart, calendar your trial/renewal dates.
- Quirky event timing: "Checkout failed" fires after a 10-minute built-in delay; "Prospect created" fires ~2 hours after creation. Don't treat them as real-time.
- All API money values are in cents — a $250 order is
"total": 25000.

Examples
Example 1: Sync SamCart sales into a CRM (developer/automation)
User says: "How do I get SamCart orders and subscription status into HubSpot automatically?"
Skill does: Sets up Notify URL webhook rules (Product Purchased, Subscription Charged/Canceled) pointing at a tokenized endpoint, verifies each payload by re-fetching via GET /orders/{id} with the sc-api header, and adds a nightly incremental GET /orders?created_at_min=… reconciliation pull following pagination.next — with the Python recipes from the platform guide.
Result: CRM stays in sync with verified data even when an unsigned webhook is missed or spoofed.
Example 2: Dunning and failed payments
User says: "Subscribers keep failing payments — how do I see and reduce involuntary churn on SamCart?"
Skill does: Explains Subscription Saver's recovery flow, wires Subscription Delinquent/Recovered webhook triggers into alerts, adds a daily GET /failed-charges poll for dunning visibility, and reviews retry/email settings.
Result: User watches delinquency in near-real-time and recovers more failed charges.
Example 3: Core vs Pro decision
User says: "Is SamCart Pro worth $199/mo, or is Core enough for my course launch?"
Skill does: Maps the user's needs against the plan gates — order bumps, 1-click upsells, A/B testing, and the Affiliate Center all require Pro — then models whether projected bump/upsell revenue (typically 10–30% AOV lift when configured) exceeds the $120/mo difference; flags the 25% annual discount and payment-processing fees on top.
Result: User picks a plan from expected AOV lift, not feature FOMO.
Troubleshooting
Webhook payload arrived but looks untrustworthy (or never arrived)
Symptom: Notify URL POSTs are unsigned, occasionally missing, or contain NULL fields.
Cause: SamCart doesn't sign payloads or document retries; missing values are sent as NULL; some triggers are delayed by design (checkout-failed +10 min, prospect-created ~2 h).
Solution: Put a secret token in the endpoint URL, verify every payload by re-fetching the object via the API, return 200 fast, and reconcile with date-filtered GET /orders polls. Check the Integration Engine's event log (last 1,000 events) when debugging.
401 Unauthorized on every API call
Symptom: All requests fail with 401 even with a key.
Cause: Key not passed in the sc-api header (it's not a Bearer token), missing Accept: application/json header, or the key was never issued (private beta).
Solution: Send sc-api: {key} and Accept: application/json over HTTPS. If you have no key, request beta access via support@samcart.com and plan integration timelines around approval.
Getting rate-limited (429) on bulk pulls
Symptom: Large order/charge exports start returning 429.
Cause: All endpoints are rate-limited; numeric limits aren't published.
Solution: Read the 429 response header for the seconds remaining, sleep that long, and resume from the last pagination.next URL. Keep pulls incremental with created_at_min/created_at_max instead of re-reading history.
