Portaly Vibe Payment Integration

Use this skill to help a human user finish a Portaly Vibe API integration quickly. Keep answers operational: prefer step lists, API request and response bullets, and copy-ready examples over long architecture explanations.

Portaly Vibe Payment Environments

Portaly Vibe Payment supports two modes per API key: live and test.

API Host

Use the following API host for both modes:

• https://portaly.cc

Payment site

Payment site URLs to which buyers are redirected for checkout:

• https://portaly.ai

Mode behavior

• Mode is set at API key creation time and cannot be changed after creation.
• A single merchant (profileId) can have both a live key and a test key active at the same time.
• All API endpoints accept both live and test keys. The mode is derived from the key, not from a request parameter.
• Test mode is intended for integration testing. Real charges are not made in test mode when using TapPay sandbox credentials.
• Plans and merchant config are shared across modes. They belong to the profileId, not to the API key mode. A plan created with a live key is visible and usable with a test key, and vice versa. Do not create duplicate plans when switching between live and test keys — query existing plans first with GET /api/creator-subscription/plans?profileId={profileId} and reuse them.

Quick Start

• Before starting, AI agent should ask the human user to claim or create a Portaly Vibe Payment API key/CallbackSecret in the Portaly Vibe Dashboard at https://portaly.ai/dashboard and store the issued secret material safely.
• Ask the human user whether they want a live or test key. Recommend starting with a test key for integration development.

1. Confirm what the human user is trying to build. Prepare for payment integration tasks such as:

1. create merchant config 2. create subscription plans 3. upload merchant or plan images (Agent should ask human user to provide image assets if needed)

1. After setup, integrate the checkout session creation and callback handling into current system:

1. create checkout session before buyer initiates payment 2. redirect buyer to Portaly vibe checkout 3. verify and consume the callback from Portaly after checkout completion 4. if the integration needs subscription lifecycle management, also wire cancel and resume APIs for recurring plans 5. if the integration needs subscriber self-service (letting subscribers manage their own subscriptions), wire the portal session API

1. Start with references/api-contract.md. Use it for endpoint lists, auth, request bodies, response bodies, and callback headers.
2. Load references/checkout-and-renewal.md only when needed. Use it only as supplemental reference when the human user asks about post-checkout charging, renewal, payout, invoice, or bridge-order behavior.
3. Return implementation-ready output. Prefer numbered steps, API endpoint lists, request and response bullets, and Node.js or TypeScript examples.

Output Style

• Write for an AI agent that is helping a human user complete integration work.
• Lead with the next concrete steps the human should take.
• Be explicit when an API can be called directly by the Agent with the Portaly Vibe Payment API key.
• Prefer using the setup APIs directly for merchant config, plan creation, plan updates, image uploads, and checkout session creation when the user has already provided valid credentials and required inputs.
• Use lists for:

- setup steps - API endpoints - required headers - request fields - response fields - callback verification steps

• Prefer concise code samples in JavaScript or TypeScript when the user does not ask for another stack.
• Keep Portaly-owned behavior and third-party-owned behavior clearly separated.

Workflow

1. Apply for the API key

• Require a Portaly Vibe Payment API key and CallbackSecret for this integration.
• Instruct the human user to apply for or create the Portaly Vibe Payment API key in the Portaly Vibe Dashboard at https://portaly.ai/dashboard.
• Ask whether the user wants a live key (pcs_live_…) or a test key (pcs_test_…). Recommend starting with a test key for development and switching to live for production.
• Be explicit that this step is performed by a human operator in Portaly Vibe Dashboard, not by the third-party integration code.
• Tell the human user to store the issued secret material safely, or store it on the user's behalf only in an appropriate secret manager or secure environment store.
• Explain that the API key is used for bearer authentication in API calls and the callbackSecret is used for verifying the authenticity of callbacks from Portaly If user asking.
• Never ask the user to paste the API key or callbackSecret into chat. Chat transcripts can be logged, cached, or echoed back by the model in summaries, diffs, or tool call arguments. Treat secrets as values the agent never needs to see in plaintext.
• Instead, instruct the human user to place the secrets into .env themselves (via their editor or shell), using this template: PORTALY_API_KEY=pcs_live_xxx # or pcs_test_xxx for test mode PORTALY_CALLBACK_SECRET=xxx
• The agent reads these at runtime via process.env.PORTALY_API_KEY (Node) or os.environ["PORTALY_API_KEY"] (Python) — it never needs the literal secret value in-context.
• If the project uses a secret manager (1Password CLI, Doppler, AWS/GCP Secrets Manager, Vault, etc.), prefer that over .env.
• Before proceeding, verify that .gitignore includes .env. If .gitignore does not exist or does not include .env, create or update it immediately. Never allow credentials to be committed to version control.
• If the user does paste a secret into chat by mistake, advise them to rotate the key in the Portaly Vibe Dashboard before using it — assume the pasted value is compromised.

2. Configure merchant settings

• Agent should perform these setup actions directly by API call with the Portaly Vibe Payment API key.
• Use the Config APIs when the human user needs to set merchant branding before any product goes live.
• AI Agent should ask the human user to provide a merchantLogo image asset, use the config image upload API to upload image to Portaly. The merchant logo is optional — if the user does not have one ready, skip this step and proceed with plan creation.
• Use PUT /api/creator-subscription/config and POST /api/creator-subscription/config/images to set up merchant branding with the Portaly Vibe Payment API key.

3. Create a valid subscription plan

• Agent should perform plan creation, plan updates, and plan image uploads directly by API call with the Portaly Vibe Payment API key.
• Before creating a new plan, always query existing plans with GET /api/creator-subscription/plans?profileId={profileId} using the current API key. Plans are shared across live and test modes — if a suitable plan already exists, reuse it instead of creating a duplicate.
• Require at least one active plan in Portaly before creating a checkout session.
• Use the Plan APIs to create or update the product basics that the human user wants to list on Portaly.
• Confirm the plan name, description, amount, currency, billing period (monthly, yearly, or one-time), pricing type (fixed or dynamic), and status match the intended product.
• For dynamic pricing plans: set pricingType to dynamic and billingPeriod to one-time. The amount is not set on the plan; instead, the caller passes amount when creating each checkout session.
• If the third party has its own product catalog, persist the Portaly planId together with the merchant's internal product or entitlement identifier.
• AI Agent should ask the human user to provide a plan image, use the plan image upload API to upload the image to Portaly.
• Treat the checkoutUrl returned by Portaly as authoritative. Do not reconstruct it from guessed domains.
• After creating or updating a plan, check the response name and description for garbled text (mojibake). If corrupted, fix shell encoding and use PUT /api/creator-subscription/plans/{planId} to correct it. See the Windows encoding note in Guardrails.

4. Create the checkout session

• Create a checkout session before the buyer initiates payment.
• Call POST /api/creator-subscription/checkout-sessions with Authorization: Bearer {api_key}.
• Send planId and optional successRedirectUrl, cancelRedirectUrl, callbackUrl, merchantOrderNumber, and string-keyed metadata.
• Persist sessionId, checkoutToken, checkoutUrl, and expiresAt on the third-party side.
• Redirect the buyer to checkoutUrl.

5. Let Portaly run hosted checkout

• Treat Portaly hosted checkout as a black box from the third-party perspective.
• Do not ask the third party to collect card tokens or implement Portaly-owned payment steps.

6. Consume the result

• The primary external confirmation is the signed callback to callbackUrl.
• Callback is only dispatched when checkout status is completed. Non-completed outcomes (failed, canceled, expired) do not trigger a callback.
• For non-completed outcomes, poll GET /api/creator-subscription/checkout-sessions/{sessionId} as a fallback.
• Use manual POST /api/creator-subscription/checkout-sessions/{sessionId}/complete only as an exception flow when the user is building a non-hosted or recovery flow.
• Current implementation contract: subscriptionId === checkoutSessionId === sessionId.
• When a recurring checkout succeeds, human user's system may use the callback's sessionId directly as the subscriptionId for later cancel or resume API calls.
• Make it explicit to the human user that this is the current Portaly implementation contract and should be persisted on their side after checkout completion.

7. Verify and persist

• Verify x-portaly-signature with the API key's callbackSecret.
• Use the exact timestamp from x-portaly-timestamp.
• Reject callbacks where x-portaly-timestamp is older than 5 minutes to prevent replay attacks. Note: x-portaly-timestamp is an ISO datetime string, not Unix seconds.
• Serialize the callback payload with stable key ordering before HMAC.
• Reference implementations live in scripts/sign_callback.py and scripts/sign_callback.mjs.
• After verification, persist sessionId, subscriptionId if present, merchantOrderNumber, paymentReference, paymentMethod, status, and the raw callback body for auditing.
• If the callback payload does not include subscriptionId, persist sessionId as the recurring subscription identifier because the current implementation uses sessionId as subscriptionId.
• Use sessionId as an idempotency key — if a callback with the same sessionId has already been processed, skip duplicate handling to avoid double fulfillment.
• callbackUrl must use HTTPS. Serving over plain HTTP exposes the callbackSecret signature and payload in transit.
• Heads up — Portaly may auto-send a welcome/upgrade email when the callback fires. A successful (status: completed) callback triggers Portaly's welcome_paid template by default. Symmetrically, a cancel call triggers subscription_canceled. If the vibe coder already sends their own purchase-confirmation or cancellation email, disable the matching template before going live with PUT /api/creator-email/templates/welcome_paid (or subscription_canceled) carrying {"enabled": false}. See the portaly-email skill for the full list of email types and disable workflow.

8. Manage recurring subscriptions

• Only recurring plans with billingPeriod = monthly | yearly support cancel or resume.
• Cancellation means stopping the next recurring charge. It is not a refund. In your system, the rights or content associated should remain active until the end of the current paid period, which is indicated by cancelEffectiveAt in the subscription record.
• Portaly currently supports merchant-system initiated subscription lifecycle actions through API key authenticated endpoints.
• Use the same Portaly Vibe Payment API key for these calls.

Recurring management APIs:

• GET /api/creator-subscription/subscriptions — list all subscriptions with pagination and filtering
• GET /api/creator-subscription/subscriptions/{subscriptionId}
• POST /api/creator-subscription/subscriptions/{subscriptionId}/cancel
• POST /api/creator-subscription/subscriptions/{subscriptionId}/resume

Order query API:

• GET /api/creator-subscription/orders — list payment/order records with pagination

Recurring management rules:

• These APIs only accept Authorization: Bearer {api_key}
• Do not use Firebase auth for merchant-system integrations
• billingPeriod = one-time does not support cancel or resume
• cancel marks the subscription as cancelAtPeriodEnd = true
• resume only works before the subscription has become fully canceled

Cancel request body:

{
  "reason": "customer_requested",
  "reasonNote": "optional note"
}

Resume request body:

{}

What to persist for recurring lifecycle:

• subscriptionId
• sessionId
• planId
• billingPeriod
• status
• cancelAtPeriodEnd
• cancelEffectiveAt

8.5. Wire invitation email CTA (optional)

If the merchant plans to use Portaly's invitation-email flow to recruit followers (waitlist signups, campaigns), the CTA in those emails redirects through https://portaly.ai/r/{code} to a waitlist landing page. By default the page is hosted by Portaly; the vibe coder can also host it themselves on their own domain by setting appBaseUrl on the merchant config.

This is a separate concern from payment integration — for the full setup, install and follow the portaly-email skill: npx skills add portaly-ai/portaly-skills --skill portaly-email.

9. Enable subscriber self-service portal (optional)

• Use this when the merchant wants subscribers to manage their own subscriptions directly.
• The merchant backend creates a portal session via POST /api/creator-subscription/portal-sessions on https://portaly.ai, then redirects the subscriber to the returned portalUrl.
• This is a server-to-server call — the API key must never be exposed to the client.
• The subscriber lands on Portaly's hosted portal page, already authenticated via the session token. No additional login is required.
• In the portal, subscribers can view subscriptions, cancel, resume, and view payment history.
• Portal sessions expire after 30 minutes.
• The merchant must provide a returnUrl so the subscriber can navigate back after managing their subscriptions.
• See Portal Session (Subscriber Self-Service) in references/api-contract.md for full endpoint details and code examples.

5. Response fields
6. Callback handling steps
7. Example code
8. Troubleshooting notes

Guardrails

• Default to test mode for development. If the loaded key starts with pcs_live_, confirm with the human user that live mode is intended before making any API call. Never silently run against production billing.
• Money-moving actions require explicit user confirmation. Before calling any of the following, state the exact action, target (subscriptionId / sessionId), and mode (live/test), then wait for the user's "yes":

- POST /subscriptions/{id}/cancel - POST /subscriptions/{id}/resume - POST /checkout-sessions/{id}/complete (manual completion) - Any plan creation/update in live mode

• Do not batch or loop these actions across multiple subscriptions without per-action confirmation.
• Prefer the hosted checkout flow whenever possible. It already handles email verification, payment-method persistence, callback dispatch, subscription creation, payment creation, invoice task creation, and order bridge writes.
• Distinguish clearly between:

- setup APIs that the Agent can call directly with the Portaly Vibe Payment API key

• Do not invent provider behavior. TapPay and 91APP differ materially.
• Do not assume callback delivery means success without checking the status and verified signature.
• Do not derive subscription state from redirect success pages alone. Redirects are UX only; callback or status query is the source of truth.
• Treat references/checkout-and-renewal.md as non-API background material. Load it only if the task explicitly touches recurring billing, payout, invoice follow-up, or bridge-order behavior.
• Windows encoding: On Windows, run chcp 65001 (cmd) or $OutputEncoding = [System.Text.Encoding]::UTF8 (PowerShell) before API calls containing non-ASCII text. If a plan's name or description comes back garbled, fix encoding and PUT the correct values.
• Rate limiting: All creator-subscription API endpoints (except POST /checkout-sessions) are rate limited. Read endpoints allow 120 requests/min, write endpoints allow 20 requests/min. If a 429 response is received, use the Retry-After header to schedule retries. When paginating through large result sets, be mindful of the rate limit budget.

Deliverables

When using this skill, aim to return one or more of:

• a minimal step-by-step integration plan for the human user
• a flat list of relevant APIs
• request and response field breakdowns
• callback verification code in the user's stack
• sample curl, fetch, or TypeScript snippets
• a troubleshooting list keyed by session status

Resources

• references/api-contract.md Use for bearer auth, endpoint contract, callback headers, payload fields, and third-party implementation shape.
• references/checkout-and-renewal.md Use only as optional background for the high-level checkout lifecycle and renewal behavior.
• scripts/sign_callback.py Use when you need a deterministic example of Portaly callback signing and verification.
• scripts/sign_callback.mjs Prefer this for Node.js, JavaScript, TypeScript, Express, or Next.js integrations.
