Our mission: hassle-free mobility

Public transport – both transit and shared mobility – is the backbone of a seamless, zero-carbon transportation system. But let’s face it: combining different modes of transport can feel like a hassle. You often need to download several apps, sign up with each provider individually, and juggle different platforms just to retrieve information or to book and pay for your trips.

This can be frustrating. Therefore, we have developed the TOMP-API to make mobility effortless for everyone. Essentially, the TOMP-API is a “technical language” that enables smooth data communication between Transport Operators and MaaS (Mobility-as-a-Service) Providers. With this API Specification, different mobility services can be integrated into one platform, allowing you to plan, book, pay for different travel modes, to access information for various transport options, and to get in touch with customer support all in one place.

Put differently, we ensure that all stakeholders in the mobility ecosystem speak the same language when it comes to facilitating MaaS. Established in 2018 with the support of the Dutch government, the TOMP-API has been implemented by numerous leasing companies in the industry and is supported by the MaaS Alliance.

Of course, we do not create our API out of thin air. As an open standard, we are in a constant dialogue with public and private stakeholders to facilitate the implementation of MaaS and the corresponding data exchange. Jointly, we define, develop, improve and maintain an internationally governed interoperable open standard for technical communication between Transport Operators and MaaS Providers. As such, we are able to develop and maintain an API that responds to the market’s needs.

But why should I care?

Adopting the TOMP-API benefits everyone in the mobility ecosystem. It enables cross-border interoperability between mobility services, enhances user experiences, drives innovation, lowers integration costs, ensures an equal level playing field, and supports sustainable mobility solutions.

For MaaS Providers, the TOMP-API enables you to integrate with different transport operators in a standardized way. This reduces integration costs significantly and improves operational efficiency. The TOMP-API increases the mobility offer for your customers and thus improves customer satisfaction.

For Transport Operators, the TOMP-API ensures standardization, thus enabling efficient integration with multiple MaaS Providers. The TOMP-API consequently broadens your customer base while lowering both integration and market exposure cost.

For Public Transport Authorities, the TOMP-API ensures standardization and easily brings together different transport services, including MaaS and shared mobility. The TOMP-API provides your travelers with more travel options at a reduced integration cost.

For Technology Partners, the TOMP-API enables integrating data from Transport Operators and MaaS Providers in a standardized way. This allows you to develop robust, future-proof integrated mobility solutions at reduced integration costs and improved operational efficiency.
