Now that the STL has its two official applications on the App Store and the Android Market, it has decided to open its data to all developers.

Before you begin, please read the terms and conditions for using the STL’s data, which you will find at the bottom of the page.

Then please register with the STL to inform us of your interest in our data, by filling out the form lower down, so that we can keep you up to date on our data. Don’t forget that this data may be updated and that this could have an impact on how well your application runs. You will also be invited to join the STL-Developers forum to make it easier to discuss matters.

Once your development is available on the platform of your choice, please let us know and it will be included in our third-party application gallery.

And lastly, when you publish your application, don’t forget to let us know. After all, we have helped you out by giving you access to our schedules!

The data on its planned schedules that the STL is making available to developers is in GTF (General Transit Feed, formely Google Transit Feed) format.

GTFS files

Last updated: December 17, 2019

Here’s the link to download the files on the STL’s schedules in GTFS format: STL GTFS files

The STL is also making the real-time data on its schedules available to developers, in XML feed format. Here is the link to the feed and the appropriate documentation in order to make good use of it.

Link to documentation: XML feed documentation

Link to the STL’s XML feed:Please read the feed documentation to access the feed, multiple commands and parameters are required to get a result set. Note the following value “a=stl” for one of the necessary parameters. This is the STL’s agency code so you can request information on our data.

Will the STL help me during my development?

The STL Developers group has been set up for this purpose; however, the STL can’t help you resolve a programming problem. As for understanding the data, if you ask a question on the Group’s site, a member of our team will answer within a reasonable amount of time. In addition, all the other members will be able to benefit from it. Or you may contact us by using the Group’s email address:

All the best with your developing!
