Orders, subscriptions, customers and licence keys from Lemon Squeezy, with refunds and changes when you ask.
Connect Lemon Squeezy with an API key and Memtro reads stores, products, orders with totals and refunds, subscriptions, customers, discount codes and licence keys in short form. Every hour the sync writes each new order into memory. When you ask, and once an administrator has granted each action by name, it can refund orders and subscription invoices, cancel, pause or change subscriptions, create checkout links and discount codes, manage customers and licence keys, and generate invoices. A refund moves money back to the customer and cannot be undone, and a plan change can charge them.
Ask in plain English from chat, your editor, a scheduled job or your own agent. The model picks the right Lemon Squeezy tool, reads what it needs, and answers with the source cited.
These tools change something in Lemon Squeezy. The model is told to use them only when you ask for exactly that, and an administrator grants each one by name to the teams that may use it; a personal connection acts only after its owner allows it.
Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with Lemon Squeezy for you. Each event can start a job, with the event as its input, and can be remembered where you choose. Lemon Squeezy signs every delivery, and one whose signature does not check out is refused before it is read.
Events and webhooksOnce Lemon Squeezy is connected, these are the kinds of things people ask. Plain questions, no syntax. If the answer lives partly in another system you have connected, Memtro looks there too.
What did we sell last week, and how much was refunded?
Has jonas@pixelforge.dev bought anything, and is his subscription still active?
Which subscriptions are past due or unpaid?
How many activations has the licence key for order #10482 used?
Refund order #10482 in full
A customer emails saying they cannot find their receipt. Memtro finds the order in Lemon Squeezy by their email, shows what they bought, the total and the receipt link, and whether their licence key is active and how many activations remain.
Jonas from Pixelforge bought the wrong plan and asks for his money back. Elena Rossi in support asks Memtro to refund order #10482 in full. Memtro reads the order, confirms the total with her and refunds it in Lemon Squeezy, so the money goes back to Jonas. The refund cannot be undone.
The teams that lean on Lemon Squeezy most, a question each of them asks, and what they connect beside it.
A record in Lemon Squeezy is rarely the whole story. Connect the systems that hold the rest and Memtro checks them together, then remembers what it learned so the next question starts further along.
Using something else for the same job, or both? Each connector has its own tools; connect as many as you like.

PaystackIn Lemon Squeezy open Settings → API → Create API key. Keys are valid for a year, and a key made while Test mode is on only sees test-mode data
In Memtro open Connections → Lemon Squeezy, paste the API key and connect. If the account has several stores, add the Store id of the one to treat as the default
The key is not scoped, so Memtro refunds or changes subscriptions only when you ask and an administrator has granted that action by name
Ask what sold this week
Chat in the dashboard, the OpenAI-compatible API, scheduled jobs, and any MCP client: Claude Code, OpenCode, Cursor, Claude Desktop. The Lemon Squeezy tools are the same everywhere.
Only when you ask, and only what it has been granted: create a checkout link for a variant, optionally prefilled or at a custom price; refund an order in full or in part (moves money back to the customer); refund a subscription invoice in full or in part (moves money back to the customer); cancel a subscription at the end of its period; change a subscription's plan, pause or unpause it, resume a cancelled one, or move its trial end or billing day; change the quantity on a quantity-billed subscription item; report usage on a usage-billed subscription item; create a discount code; delete a discount code permanently; create a customer; update a customer's name, email or location, or archive them; change a license key's activation limit or expiry, or disable it; generate a downloadable invoice for an order. Every other tool reads, searches or lists. The Connections page labels the tools that act, an administrator grants each one by name to the teams that may use it, and a personal connection acts only after its owner allows it.
A personal connection serves only your own requests. A shared connection serves the organisation: everyone, or only the teams an admin chooses. Admins can always add shared connections; other members need the permission.
Credentials are encrypted at rest. Tool results are cached briefly so agent loops do not repeat identical calls, and the facts the model extracts are saved to your organisation's memory with provenance (system, record and link) so they can be checked and superseded. An hourly sync anchors recently changed Lemon Squeezy records into memory as entities.
API key. In Lemon Squeezy open Settings → API → Create API key. Keys are valid for a year, and a key made while Test mode is on only sees test-mode data.
Yes. Turn events on in the connection's Events tab on the Connections page, choose the kinds you want, and Memtro registers its address with Lemon Squeezy for you. A job set to start "When an event arrives" then runs once for each matching event, with the event as its input. The run treats the event as outside data, never as instructions, and anything the run remembers is kept as unverified.
Seven-day free trial, then one monthly price per organisation. Connectors, jobs and memory are never metered.
