TomTom Audio Traffic is a webservice. The user gains access to Audio Traffic using HTTP GET requests and it is parameterized using URL parameters. Depending on the parameters the caller gets traffic events around a given location (use case [AroundMe]) or traffic events on potential routes to a given destination (use case [Destination]).

Please notice the available market coverage. Requests for coordinates inside unsupported countries will result in an error or empty content.

The service provides endpoints for two different output formats. The first traffic report output format is audio (formal Audio), and the second is text.

The general URL scheme is as follows:[format]?parameters
