Developer Resources

On May 17, 2021, we will disable TLS 1.0, TLS 1.1, and 3DES encryption for all APIs, including GTFS, hosted at, leaving only TLS 1.2 for HTTPS encryption. We recommend confirming that your application is able to access WMATA APIs using TLS 1.2 before that time.

Metro has resources available for developers to create applications for desktop, web or mobile devices. The Metro Transparent Data Sets API includes the order and location of rail stations by line, train arrival predictions for each station, service alerts, and elevator/escalator status. The General Transit Feed Specification (GTFS) download provides the same official schedule data that supports Metro's online trip planner. RSS feeds provide subscriptions to Metro advisories and news releases and GTFS schedule releases.

As more resources are made available, they will be announced here.

The GTFS feeds provide schedule and real-time data for Metrobus and Metrorail. Developers can access the feeds through the WMATA API portal. If you do not already use the API portal, you must register and receive an official API key to get the data. Register to receive a key.
