Payleven, the Square equivalent for the world outside of the US, has launched an API to complement its mobile payment device. Prior to the API, use of Payleven's mobile payment device required downloading the Payleven app (similar to Square's current model). However, the API allows developers to integrate Payleven's functionality within third party apps.
Xero, cloud accounting software provider, has expanded its Payroll product to integrate with other applications via the Payroll API. The Payroll API allows developers to build add-on apps to work alongside Xero products, or integrate Xero functionality into existing apps and workflows. Xero's target audience remains in the SMB space who typically cannot afford massive onsite, dedicated ERP and accounting software packages.
