App development
Rootline allows you to run your own app on the payment device. The payment devices Rootline offers are the A920Pro, A77 and A35 from PAX running a modified Android 10 or later.
Rootline offers the Connect SDK to integrate payments within your app.
PAX Developer Portal
Your app will be published through the PAX Developer Portal. The below steps describe how to register with PAX as a developer and release your app.
Registering with PAX
To publish your own app you need to register with PAX as a developer using the following link: https://paxemea.whatspos.com/developer. After you have registered with PAX, inform our support team by sending an email to support@rootline.com and provide the email address that was used to create the PAX developer account. Our team will link your developer account accordingly.
Adding and publishing an app in the PAX Developer Portal
In the PAX Developer Portal click on "+ NEW APP" and provide the name of your app. Upload the latest version of your APK and choose the app type:
