Shuttle belongs to your Shopify store, not to one person. So your staff and collaborators can work in Shuttle without their own Etsy login. They use the Etsy connection that was saved when your Etsy shop was connected.
Who can use Shuttle on my store?
Anyone your Shopify store lets open Shuttle can use it. Shuttle has no separate user accounts, so everyone sees the same Shuttle account, the same Etsy shops and the same settings.
People who open Shuttle on your store can:
transfer products between Etsy and Shopify
match products
update products
change settings
You decide who can open Shuttle in your Shopify store, not in Shuttle.
Does a staff member need to log in to Etsy to use Shuttle?
No. Day-to-day work in Shuttle needs no Etsy login, because Shuttle uses the Etsy connection saved when the shop was connected. When that connection expires, Shuttle renews it with Etsy on its own, so nobody has to sign in again for that.
When does someone need to sign in to Etsy?
Someone has to sign in to Etsy and approve access in only three cases:
connecting your first Etsy shop to Shuttle
adding another Etsy shop with Add Etsy shop in Settings > Connected Shops
reconnecting a shop that shows Reconnect needed in Settings > Connected Shops
Switch between connected Etsy shops without an Etsy login
Switching to another Etsy shop you have already connected needs no Etsy login. Go to Settings > Connected Shops and choose Activate next to the shop you want to work in.
The active Etsy shop is shared by everyone on your store. When one person activates a different shop, manual transfers and settings switch to that shop for everyone using Shuttle.
Which Etsy shop gets connected?
The person who approves access decides which Etsy shop gets connected. Shuttle connects the shop that belongs to the Etsy account signed in at that moment.
So before anyone chooses Connect to Etsy, check that the browser is signed in to the Etsy account that owns the right shop. If a collaborator approves with their own Etsy account, Shuttle connects their shop instead of yours.
Reconnect an Etsy shop that shows Reconnect needed
An Etsy shop shows Reconnect needed in Settings > Connected Shops when Shuttle can no longer reach it. Shuttle cannot sync products, orders or reviews for that shop until someone reconnects it.
In the same browser, sign in to the Etsy account that owns the shop.
In Shuttle, go to Settings > Connected Shops.
Choose Reconnect next to the shop.
Choose Connect to Etsy, then approve access on Etsy.
Etsy then sends you back to Shuttle. Approving with a different Etsy account does not fix the shop that needs reconnecting.
Who gets the email when an Etsy shop needs reconnecting?
Shuttle sends the reconnect email to your store's address, not to the person using Shuttle. The email goes to the Notifications email in Settings > Alerts & Notifications. If that field is empty, the email goes to your Shopify store's email address.
