  • Integrating Lemon Squeezy billing
  • SKILL.md covers Architecture, Choose an approach, Required environment variables and End-to-end workflow, plus 2 more sections

What it does

Lemon Squeezy Integration is an agent skill from pockethost/pockethost. Full Lemon Squeezy integration — REST API, @lemonsqueezy/lemonsqueezy.js server SDK, Lemon.js checkout overlays, webhooks, customdata, and subscriptions. Use when integrating Lemon Squeezy billing, checkout, webhooks, LS API, Lemon.js, or subscription provisioning into an application.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `api.md`, `integration-checklist.md` and `lemonjs.md`).

It sits in Backend & APIs, covering Webhooks and REST APIs. The repository describes itself as: Open source multitenant PocketBase server. The licence is MIT.

When your agent uses it

  • Integrating Lemon Squeezy billing
  • Subscription provisioning into an application

Example prompts

  • “/lemon-squeezy-integration”

Requirements

  • A credential in LEMONSQUEEZY_API_KEY
  • A credential in LEMONSQUEEZY_WEBHOOK_SECRET

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Store setup
  2. Checkout
  3. Webhook endpoint
  4. Persist subscription state

What it can do on your machine

Read from SKILL.md and the folder at commit 82c9ba3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • store.pockethost.io

    Also links to:

    • docs.lemonsqueezy.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • LEMONSQUEEZY_API_KEY
    • LEMONSQUEEZY_WEBHOOK_SECRET

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Lemon Squeezy Integration loads about 1.1k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 417 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~78
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Full Lemon Squeezy integration — REST API, @lemonsqueezy/lemonsqueezy.js server SDK, Lemon.js checkout overlays, webhooks, custom_data, and subscriptions. Use when integrating Lemon Squeezy billing, checkout, webhooks, LS API, Lemon.js, or subscription provisioning into an application.

Lemon Squeezy Integration

Official docs: https://docs.lemonsqueezy.com/

Architecture

Three layers — use all three for a production SaaS integration:

LayerToolRuns on
Checkout UXLemon.js + checkout URLsBrowser
Admin / dynamic checkoutREST API or @lemonsqueezy/lemonsqueezy.jsServer only
ProvisioningWebhooksServer endpoint

Never expose LEMONSQUEEZY_API_KEY in client code. The npm SDK is server-only.

Golden rule: Webhooks are the source of truth for granting access. Lemon.js Checkout.Success is UX-only — do not provision solely from client events.

Choose an approach

NeedUse
Static pricing pageDashboard checkout URLs + optional Lemon.js overlay
Per-user checkout with custom dataAppend checkout[custom][user_id] to URL, or create checkout via API
Dynamic pricing / on-demand checkoutServer: createCheckout → open URL with Lemon.js
Grant/revoke access after paymentWebhook handler
Customer billing portalsubscription.urls.update_payment_method from API + Lemon.js overlay

Required environment variables

VariablePurpose
LEMONSQUEEZY_API_KEYServer API auth (Settings → API)
LEMONSQUEEZY_STORE_IDStore ID for checkout creation
LEMONSQUEEZY_WEBHOOK_SECRETVerify incoming webhook X-Signature

Use test mode keys until production. Docs: https://docs.lemonsqueezy.com/help/getting-started/test-mode

End-to-end workflow

1. Store setup

Create products and variants in the LS dashboard (or sync via API). Record store_id, product_id, and variant_id for each plan.

2. Checkout

Static URL:

https://[STORE].lemonsqueezy.com/checkout/buy/[VARIANT_ID]

With user linking (required for webhook provisioning):

?checkout[custom][user_id]=USER_ID&checkout[email]=user@example.com

Overlay: Load Lemon.js, add lemonsqueezy-button class to links, or call LemonSqueezy.Url.Open(url).

Dynamic: Server creates checkout via API/SDK → use data.attributes.url from response.

Share /checkout/buy/ URLs only. Do not share converted /checkout/?cart= URLs — they are single-use per customer.

PocketHost uses custom domain URLs like https://store.pockethost.io/buy/... — see pockethost.md.

Show full SKILL.md (181 more words)Show less
3. Webhook endpoint
  1. Register URL in Settings → Webhooks (or via API)
  2. Verify HMAC-SHA256 of the raw request body against X-Signature header
  3. Read meta.event_name and meta.custom_data
  4. Update your database idempotently
  5. Return 200 quickly

Key events: order_created, subscription_created, subscription_updated, subscription_expired, subscription_cancelled, order_refunded, subscription_payment_refunded

4. Persist subscription state

Store at minimum: LS subscription/order id, status, variant_id, renews_at, ends_at, and your internal plan tier mapping.

On refund/expiry/cancel → revoke or decrement access.

Common tasks

Add a new plan
  1. Create variant in LS dashboard
  2. Add checkout URL to frontend (with checkout[custom][user_id])
  3. Add {product_id}-{variant_id} to webhook allowlist and product handler map
  4. Map variant → internal subscription fields
Debug a failed webhook
  1. Confirm webhook URL and signing secret match env
  2. Check LS dashboard webhook log for payload and response
  3. Verify signature uses raw body (not re-serialized JSON)
  4. Confirm meta.custom_data.user_id was passed at checkout
  5. Confirm product/variant ID is in your handler allowlist
