Browse and connect add-ons
Connect your store to carriers, marketplaces, payment providers, accounting systems, and analytics tools from the Add-ons page.
Add-ons connect your store to services outside YNS — the courier who collects your parcels, the marketplace you also sell on, the accounting system your bookkeeper insists on. Open Add-ons from Settings to browse what's available.
How the page works
Add-ons are grouped by category, and there's a search box if you know what you're after. Open any card to see what the add-on does and connect it. Some ask you to sign in with the provider; others need an API key you copy from their dashboard.
Add-ons currently in beta are free to use while they're in beta.

Tip: The email marketing add-ons sync your customers and their orders to the other tool, so its automations can act on what people actually bought. If you only want to send campaigns, you don't need any of them — see Send newsletters & grow subscribers.
Other services appear on the page marked Coming soon, so you can see what's on the way.
Tip: Connect one add-on at a time and check your storefront and orders afterwards. If something breaks, you know exactly which one to blame.
Keep connections healthy
Authorizations expire — marketplace and carrier logins in particular. When one does, you'll get an email and the failure shows up on your Issues page. Reconnecting from the add-on's card is usually all it takes.
FAQ
Do add-ons cost extra?
Add-ons in beta are free while they're in beta. Any fees charged by the service itself — courier rates, marketplace commission, your accounting subscription — stay between you and that provider.
What's the difference between add-ons and modules?
Add-ons connect you to outside services. Modules are capabilities built into YNS, like blog, reviews, or wishlists — see Turn features on and off with Modules.
The add-on I want says "Coming soon".
It's on the roadmap but not connectable yet. Meanwhile, the store API and product feeds cover a lot of ground.
Can I disconnect an add-on?
Yes. Open its card and disconnect. Your store keeps working — you just stop syncing with that service.
