Quick info


What is an API?

API stands for Application Programming Interface. An API is a software intermediary that allows two applications to talk to each other. In other words, an API is the messenger that delivers your request to the provider that you’re requesting it from and then delivers the response back to you. An API makes it easier to develop an integration by providing the building blocks.


Basically, all the things you can do a user in the front-end of our software, you can also do with our API. You can retrieve, create, edit and delete data with respect to master data and transactional data. Master data includes clients, projects, resources, skills and users. Transactional data includes resource bookings, time sheets, Gantt Chart, invoices, quotes, cost items and purchase invoices.

Technical details

The Timewax API is available at and is realized as an http(s) service which by a POST request sends data to the XML Timewax server. Based on this request XML data is returned. Each service has its own URL, request and response definition. All services are authorized based on a token obtained using the Timewax credentials. For the technical documentation, see this support article.
