OpenStockConnect Lemon Squeezy
Sell through Lemon Squeezy as merchant of record, so it handles tax and chargebacks.
Set it up#
Create an API key
In Lemon Squeezy, open Settings → API and create an API key.
Copy your store ID
Open Settings → Stores and copy the number next to your store. The store currency must match your OpenStock store currency.
Create one product for OpenStock
Create a single product, for example “Order”, with any price. Each checkout replaces its name and price, so you only need one. Copy its variant ID.
Add the webhook
Open Settings → Webhooks, add the webhook URL from the Connect dialog, choose a signing secret and tick order_created and order_refunded.
Connect in the dashboard
Open Payments → Payment setup → Lemon Squeezy, paste the API key, store ID, variant ID and signing secret, and select Connect. Choose Sandbox to create test-mode checkouts.
Why the webhook is required#
Lemon Squeezy can’t look up an order by our order number, so the signed order_created webhook links its order to yours. Without it, orders stay pending.
If something does not work#
What to check
If checkout fails with a currency error, set your Lemon Squeezy store currency to your OpenStock store currency. If orders stay pending, check the webhook’s signing secret and that order_created is ticked.
