This project aims to implement the Go bindings for the EMT Rest API.
The EMT is the public transportation company from Madrid city. Using this API can be useful for getting live information from the service (waiting times, stop locations, etc). For full Rest API referece, please reffer to HERE.

IMPORTANT - So far it implements the Block 1 (User identity for login) and Block 3 (Transport BusEMTMad). If this project makes sense for somebody, we can continue implementing the rest of the API.

To start using it, we have to create a APIClient struct. To do so, first a ClientConfig struct needs to be created with your credentials:

config := goemt.ClientConfig{
		Enpoint:   "https://openapi.emtmadrid.es/v2",
		XClientID: "YOUR_XCLIENTID",
		PassKey:   "YOUR_PASSKEY",

*There are three kind of autentication. Basic, advanced and protected. The one used in the example is protected. Depending on which values from the ClientConfig struct are set, one or another will be used. Please reffer to HERE to check which values your need to set for each login method.

Once a config struct is created, the Connect() function must be used to log in:

api, err := goemt.Connect(config)
	if err != nil {
		panic(err)
	}
	defer api.Logout()

    //Do your thing

Once you're logged in the platform, you can use the different functions from busemtmad package (I.E. GetTimeArrivalBus() (Check the examples folder for some example of using the API), which returns waiting times). When you are done, use the Logout() method from the APIClient to close the session agains the EMT server.

Pull requests more than welcome!

Known issues:

• GetTimeTableStartStop function doesn't work because platform returns Error code 90: Error managing internal services
