Create a Public app, not a Custom app — Custom apps are scoped to a single merchant, so they can’t be installed by multiple merchants.
1
Create a developer account
Go to the SHOPLINE Partner Portal and sign up for a developer account.
2
Create a new app
- In the Partner Portal, go to Apps, then click + Create App and choose Public app (not Custom app).
- Enter a name, and set the callback URL to
https://api.nango.dev/oauth/callback. - The App URL isn’t used by Nango, so you can enter anything there.

Get your credentials
Once the app is created, open it and copy its App Key and App Secret — you’ll use these as the client ID and client secret when configuring the integration in Nango.
