Documentation
Start building with Merida
Sell products, run subscriptions, and ship invoices through one REST API, one product catalog, and one signed webhook stream. Pick the checkout style that fits where you're integrating.
Three ways to integrate
Checkout Links
Create a link in the dashboard and share it anywhere to collect payments. No code needed.
Embedded Checkout
Add a checkout that opens right on your site, styled to match your brand. No redirects.
Checkout API
Build your own flow. Create checkouts from your backend with custom buyer info and metadata.
Guides
Quickstart
Make your first sale in five minutes. One API call, one checkout URL, one webhook.
Products
What you sell. One-off or recurring, with one or more prices. The thing every checkout points at.
Customers
Connect a Merida customer back to a user record in your own system. One ID does the join.
Discounts
Create a code in the dashboard, apply it on any checkout. Works for one-off and subscriptions.
Subscriptions
Charge customers on a recurring schedule. Handle plan changes, pauses, and cancels.
Entitlements
What each customer is allowed to access after they pay, and how to check it from your code.
Meters
Charge based on usage. Send events as work happens and Merida turns them into balances.
Invoices
When invoices are generated, the printable HTML endpoint, and the events that keep your backend in sync.
Customer portal
Self-service links for buyers: cancel, pause, resume, access past invoices.
