[describe what you need help with in Checkout Page]
Checkout Page (checkoutpage.com) is a no-code, Stripe-based hosted checkout builder for
creators and small teams: branded checkout pages for digital products, subscriptions, payment
plans, pay-what-you-want, and event tickets, plus form/lead capture — with order bumps,
1-click upsells, and cart-abandonment recovery. 0% platform transaction fees, but it is
not a Merchant of Record (runs on your Stripe account → you own tax). Its edge is that forms,
checkout, events, and customers share one REST API + native MCP server.
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 Checkout Page data (payments/subscriptions/customers) with a CRM, warehouse, or app
B) Set up or debug the conversion webhook
C) Build/query checkouts, forms, or coupons via the native MCP server
D) Configure a checkout, event-ticket page, upsell, or form in the product
E) Decide on a plan (Launch vs Grow vs Enterprise) or understand fees/caps
Do you have your API key / Stripe connected? The API key comes from the dashboard; the MCP
connects via OAuth and needs a Stripe-connected account.
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, or checkout-conversion strategy across tools (bump/upsell design, cart abandonment)
Choosing a Merchant of Record for global tax/VAT (Checkout Page is NOT one)
/sales-merchant-of-record {question}
Migrating active subscriptions between billing platforms without double-billing
/sales-subscription-billing {question}
Running an affiliate program (Checkout Page integrates Rewardful/Tolt)
/sales-affiliate-program {question}
When routing, give the exact command: "This is a {domain} question — run: "
/sales-checkout {original question}
Otherwise, answer Checkout Page-specific questions directly using Step 3.
Step 3 — Checkout Page platform reference
Read references/platform-guide.md for the full reference — capabilities & automation
surface (what's API-, webhook-, MCP-accessible vs UI-only), pricing/plan gates and the
sales-volume cap, data model (decimal-string money, Stripe id cross-reference), and quick-start
recipes (webhook listener, nightly incremental pull, MCP event-checkout build).
For raw endpoint detail, auth, pagination, rate limits, verbatim conversion webhook payloads,
and MCP tool list, read references/checkoutpage-api-reference.md.
Answer using only the relevant section — don't dump the full reference.
Step 4 — Actionable guidance
Treat the webhook as a hint, the API as truth. Register a store-level webhook (fires for
every page) and branch on object — payment, subscription, or submission — to route
each conversion type. The conversion payload has no documented HMAC signature or retry
policy — post to a tokenized/unguessable endpoint URL, re-fetch the object by id via the REST
API before provisioning access or moving money, dedupe on orderId, and keep a polling backup.
Re-check the live docs for a signing scheme before trusting deliveries.
Parse money as a decimal string, not cents. Amounts arrive as "23.99" in the display
currency — unlike SamCart/Sellfy (cents). Read Stripe object ids (stripePaymentId,
stripeSubscriptionId, stripeCustomerId) straight from the payload to reconcile in Stripe.
Say it's not a Merchant of Record. Checkout Page runs on the user's own Stripe account, so
they are the seller of record and own sales-tax/VAT (Stripe Tax can calculate). For global
tax handled for them, point to /sales-merchant-of-record.
Model the sales-volume cap, not features. ~99% of features are on every plan; plans differ
mainly by monthly sales volume, support, and custom domains — forecast expected sales when
choosing Launch vs Grow. Present all pricing as best-effort and tell the user to verify current
numbers at checkoutpage.com/pricing.
Reach for the native MCP for build/query tasks.claude mcp add --transport http checkoutpage https://mcp.checkoutpage.com then /mcp to authenticate — because forms + Stripe checkout share
one MCP (13 tools), an agent can build a paid event-registration page end-to-end from a prompt.
Respect the rate limits. 500 req/min per store, 100 req/min per key → on 429, back off and
resume from the last cursor (starting_after = last id); keep bulk pulls incremental.
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/caps and the
webhook-signature status, which may have changed.
Conversion webhooks appear unsigned — no documented HMAC header, signing secret, or retry
policy. Tokenize the endpoint URL, verify by re-fetching via the API, and keep a polling backup.
Money is a decimal string in the display currency ("23.99"), not cents — don't divide by 100.
Stripe-only. Payments run exclusively through Stripe; there's no PayPal/other-gateway option.
If the user needs an alternate processor, this is a hard limit — flag it early.
Not a Merchant of Record — the seller owns VAT/GST/sales tax (Stripe Tax available).
Volume-cap pricing. Crossing a plan's monthly sales ceiling forces an upgrade; features are
mostly not gated — forecast sales, not features.
trailStart is a vendor typo in the subscription payload (trial start); trialEnd is
spelled correctly. Read fields exactly as sent.
Docs are partly JS-rendered and show both REST (GET /v1/checkout-pages) and action
(/v1/checkout-pages/list) path styles — confirm the exact spelling against live docs before coding.

Examples
Example 1: Sync Checkout Page sales into a CRM (developer/automation)
User says: "How do I get every Checkout Page sale and subscription into HubSpot automatically?"
Skill does: Sets up a store-level webhook at a tokenized URL, branches on object
(payment/subscription/submission), ignores livemode:false in production, and — because the
payload is unsigned — re-fetches the customer/payment by id via GET /v1/customers/{id} before
upserting; parses amount as a decimal string, maps queryParameters UTMs for attribution, and
adds a nightly cursor-paginated GET /v1/payments reconciliation pull (per the platform-guide recipes).
Result: HubSpot stays in sync with verified data even if an unsigned webhook is missed or spoofed.
Example 2: Build a paid event-registration page from a prompt (MCP)
User says: "Can I make a ticketed workshop checkout with an attendee name and dietary field without clicking around?"
Skill does: Walks them through claude mcp add --transport http checkoutpage https://mcp.checkoutpage.com
/mcp OAuth, then prompts the agent to call create_checkout_page for the ticket, create_form
for the attendee fields, and create_coupon for a launch code — noting forms + Stripe checkout
share one MCP so the whole flow runs in chat.
Result: A live paid event page with custom fields, built end-to-end from a single prompt.
Example 3: Launch vs Grow plan decision
User says: "I'm doing about $8K/mo in digital sales — is Checkout Page's Launch plan enough or do I need Grow?"
Skill does: Flags that Launch caps around ~$3K/mo in sales while $8K/mo lands in a Grow volume
tier, so the cap — not features (which are ~all shared) — forces the choice; notes 0% platform fees
(Stripe's ~2.9%+30¢ still applies) and presents pricing as best-effort to verify at checkoutpage.com/pricing.
Result: User picks Grow from their sales volume, not feature FOMO.
Troubleshooting
The conversion webhook fired but I don't trust it (or it never arrived)
Symptom: Payloads look spoofable, occasionally missing, or contain test data in production.
Cause: No documented HMAC signature or retry policy; livemode:false events come from the
dashboard "Test payments" tool; there's no documented delivery log.
Solution: Put a secret token in the endpoint URL path, verify every payload by re-fetching the
object via the REST API, drop livemode:false in prod, return 200 fast, dedupe on orderId, and
reconcile nightly with a cursor-paginated GET /v1/payments pull.
401 Unauthorized on every API call
Symptom: All requests fail with 401 even with a key.
Cause: Key not sent as a Bearer token, or generated for the wrong store/environment.
Solution: Send Authorization: Bearer YOUR_API_KEY over HTTPS with a key generated in the
dashboard for the correct store. For the MCP, authenticate via OAuth (/mcp) on a Stripe-connected account.
429 Too Many Requests on a bulk export
Symptom: Large payment/customer pulls start returning 429.
Cause: 500 req/min per store, 100 req/min per API key.
Solution: Back off on 429 (exponential, start ~1–2s) and resume from the last cursor
(starting_after = last object id); page at limit=100; keep pulls incremental rather than
re-reading history.
