The billomat[API] is an open data and programming interface which enables you to access the data in your Billomat account via HTTP and XML/JSON. With this, online and desktop applications can be created which seamlessly integrate into your Billomat account.

Here are a few ideas for potential applications of the API:

  • Your own importing tools (CSV data, ERP-, WaWi- und CRM-systems, ...)
  • Automatic invoicing and billing of transactions from online shops
  • Individual evaluations and data analyses
  • Data transfer to accountants and tax consultants
  • Linking to online payment systems
  • Widgets for iGoogle, netvibes, OSX Dashboard, Windows 7 Gadgets, ...
  • Native clients for mobile platforms (iPhone, Android, Symbian, Windows Mobile)

Or quite different mashups which we can't even imagine yet. It's up to you to test out the potential of the billomat[API] to its limits, and to extend the boundaries of the possible!

Whether you use the billomat[API] just for your own personal requirements and develop a link to internal systems, or whether you want to make it publicly available – the decision is yours alone. You can even offer your connection on a charging basis (even if we're pleased about connections available free of charge, of course). It's entirely up to you!
