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: 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.
