POGOLib is written in C# and aims to be a community-driven PokémonGo API. Feel free to submit pull requests.

The library is a bit low-level now but the goal is to provide a high-level library while also allowing low-level request crafting.

Run Install-Package POGOLib.Official -Pre in Tools > NuGet Package Manager > Package Manager Console .

Right click your project in Visual Studio, click Manage NuGet Packages.., make sure Browse is pressed and Include prereleases is checked. Search for POGOLib.Official and press Install.

POGOLib supports Pokemon Trainer Club and Google.

We also allow you to store the session.AccessToken to a file using JsonConvert.SerializeObject(accessToken, Formatting.Indented) , using this you can cache your authenticated sessions and load them later by using JsonConvert.DeserializeObject<AccessToken>("json here").

You can view an example of how I implemented this in the demo.

When PokémonGo tells POGOLib that the authentication token is no longer valid, we try to re-authenticate. This happens on intervals of 5, 10, 15, 20, 30... 60 (max) seconds. It keeps trying to re-authenticate. All other remote procedure calls that tried to request data will be stopped and continue when the session has re-authenticated. It will be like nothing happened.

When the session has successful re-authenticated, we fire an event. You can subscribe to the event to receive a notification.

var session = Login.GetSession("username", "password", LoginProvider.PokemonTrainerClub, 51.507351, -0.127758);

session.AccessTokenUpdated += (sender, eventArgs) =>
{
	// Save to file.. 
	// session.AccessToken
};

session.Startup();

The map, inventory and player are automatically updated by the heartbeat.

The heartbeat is checks every second if:

• the seconds since the last heartbeat is greater than or equal to the maximum allowed refresh seconds of the game settings;
• the distance moved is greater than or equal to the minimum allowed distance of the game settings;

If one of these is true, an heartbeat will be sent. This automatically fetches the map data surrounding your current position, your inventory data and the game settings.

If you want to receive a notification when these update, you can subscribe to the following events.

var session = Login.GetSession("username", "password", LoginProvider.PokemonTrainerClub, 51.507351, -0.127758);

session.Player.Inventory.Update += (sender, eventArgs) =>
{
	// Access updated inventory: session.Player.Inventory
	Console.WriteLine("Inventory was updated.");
};
session.Map.Update += (sender, eventArgs) =>
{
	// Access updated map: session.Map
	Console.WriteLine("Map was updated.");
};

session.Startup();

Make sure you start the session after subscribing to the events.

This is for now almost the only way to receive data. It's easy though!

If you want to know what requests are available, click here. If you want to know what responses belong to the requests, click here.

If you want to know what kind of data is available, have a look through all POGOProtos files.

You can send a request and parse the response like this.

var session = Login.GetSession("username", "password", LoginProvider.PokemonTrainerClub, 51.507351, -0.127758);
session.Startup();

var fortDetailsBytes = session.RpcClient.SendRemoteProcedureCall(new Request
{
	RequestType = RequestType.FortDetails,
	RequestMessage = new FortDetailsMessage
	{
		FortId = "e4a5b5a63cf34100bd620c598597f21c.12",
		Latitude = 51.507335,
		Longitude = -0.127689
	}.ToByteString()
});
var fortDetailsResponse = FortDetailsResponse.Parser.ParseFrom(fortDetailsBytes);
					
Console.WriteLine(JsonConvert.SerializeObject(fortDetailsResponse, Formatting.Indented));

Output:

{
  "FortId": "e4a5b5a63cf34100bd620c598597f21c.12",
  "TeamColor": 0,
  "PokemonData": null,

  ],

      "ExpirationTimestampMs": 1469238785723,

    }
  ]
}

This example logs in, retrieves nearby pokestops, checks if you have already searched them, if you have not, he will check the distance between you and the pokestop. If you are close enough to the pokestop, he will search it and display the results.

var session = Login.GetSession("username", "password", LoginProvider.PokemonTrainerClub, 51.507351, -0.127758);
session.Startup();

Console.WriteLine($"I have caught {session.Player.Stats.PokemonsCaptured} Pokémon.");
Console.WriteLine($"I have visisted {session.Player.Stats.PokeStopVisits} pokestops.");

foreach (var fortData in session.Map.GetFortsSortedByDistance(f => f.Type == FortType.Checkpoint && f.LureInfo != null))
{
	if (fortData.CooldownCompleteTimestampMs <= TimeUtil.GetCurrentTimestampInMilliseconds())
	{
		var playerDistance = session.Player.DistanceTo(fortData.Latitude, fortData.Longitude);
		if (playerDistance <= session.GlobalSettings.FortSettings.InteractionRangeMeters)
		{
			var fortSearchResponseBytestring = session.RpcClient.SendRemoteProcedureCall(new Request
			{
				RequestType = RequestType.FortSearch,
				RequestMessage = new FortSearchMessage
				{
					FortId = fortData.Id,
					FortLatitude = fortData.Latitude,
					FortLongitude = fortData.Longitude,
					PlayerLatitude = session.Player.Latitude,
					PlayerLongitude = session.Player.Longitude
				}.ToByteString()
			});

			var fortSearchResponse = FortSearchResponse.Parser.ParseFrom(fortSearchResponseBytestring);

			Console.WriteLine($"{playerDistance}: {fortSearchResponse.Result}");

			foreach (var itemAward in fortSearchResponse.ItemsAwarded)
			{
				Console.WriteLine($"\t({itemAward.ItemCount}) {itemAward.ItemId}");
			}
		}
		else
		{
			Console.WriteLine("Out of range.");
		}
	}
	else
	{
		Console.WriteLine("Cooldown.");
	}
}

In order to build POGOLib you need to have two things installed:

• Visual Studio 2015
• .NET Framework 4.6.1

Open POGO.sln with Visual Studio 2015 and go to Build > Build Solution. Visual Studio should automatically download the required libraries for you through NuGet.

You can find the DLL here: POGO\POGOLib\bin\Debug\POGOLib.dll.
