Creating the DblEu Object

To use the library, you must create the DblEu.Builder() object first. The API requires an API Key and an id

See API Key and ID

Example

DblEu api = new DblEu.Builder()
        .setAPIKey("key") //Set the API Keys
        .setId("id") //Set the client id
        .build(); //Build the object

Listening to events

You can catch events to work even better with the API

Example

public class DblEuEvents extends DblEuListerns { //Extend all event listeners from the DblEuListerns class
    
    //Ready event
    @Override
    public void onReady(ReadyEvent event) {
        System.out.println("Version of Library: " + event.getDblEu().version()); //Printing the Library-Version
    }
    
}

You can catch multiple events in one class

Example

public class DblEuEvents extends DblEuListerns { //Extend all event listeners from the DblEuListerns class

    //Ready event
    @Override
    public void onReady(ReadyEvent event) {
        System.out.println("Version of Library: " + event.getDblEu().version()); //Printing the Library-Version
    }

    //Vote event
    @Override
    public void onVote(VoteEvent event) {
        System.out.println("Received a vote from " + event.getVote().getVoter().getName() + " (" + event.getVote().getVoter().getId() + ")"); //Printing information
    }

}

Note
You need to register all of these listeners before you build the DblEu object.

Example

DblEu api = new DblEu.Builder()
        .setAPIKey("key") //Set the API Keys
        .setId("id") //Set the client id
        .addEventListener(new DblEuEvents()) //Add an event listener
        .build(); //Build the object

See Creating the DblEu-Object

Post data

You can post data which will be shown on your bots page.

DblEu api = ...;
PostData postData = new DataBuilder()
   .setServers(servers)
   .build();
api.postData(postData).queue((consumer) -> {
   System.out.println("Sent data");
});

Fetching votes

You can also fetch all current votes

Example

public static void printVotes(DblEu api) {
   api.fetchVotes().queue((votes) -> {
      System.out.println("All votes:");
      for(Vote v : votes) System.out.println("   - by "+v.getVoter().getName()+" at "+v.getTime());
      if(votes.size() == 0) System.out.println("There are no votes");
   },
   (e) -> e.printStackTrace());
}

Working with RatelimitManagers

You can work with a RatelimtManager to prevent temporary bans

Catching Exceptions

@Override
public void onReady(ReadyEvent event) {
   int servers = 0;
   DataBuilder dataBuilder = new DataBuilder()
      .setServers(servers);
   try {
      event.getDblEu().postData(dataBuilder.build()).queue((consumer) -> {
         System.out.println("Sent data");
      });
   } catch(RatelimitReachedException ex) {
      System.out.println("Could not send data");
   }
}

See Listening to events, Post data

Using the Throwable of the .queue()

@Override
public void onReady(ReadyEvent event) {
   int servers = 0;
   PostData postData = new DataBuilder()
      .setServers(servers)
      .build();
   event.getDblEu().postData(postData).queue((consumer) -> {
      System.out.println("Sent data");
   },
   (throwable) -> {
      System.out.println("Could not send data");
   });
}

See Listening to events, Post data

Using the manager

@Override
public void onReady(ReadyEvent event) {
   RatelimitManager manager = event.getDblEu().getRatelimitManager();
   if(manager.postData().getAvailableRequests() != 0) event.getDblEu().postData(
      new DataBuilder()
         .setServers(0)
         .build()
      ).queue((consumer) -> {
         System.out.println("Sent data");
      }); else System.out.println("Could not send data");
}

See Listening to events, Post data

Simulate Events

You can simulate events to test features etc.

Example

api.simulateEvent(ReadyEvent.class, api.getSimulationBuilder().build()).queue((event) -> {
   System.out.println("Version of simulated ready event: "+event.getDblEu().version());
})

Check the Javadoc, examples, wiki or ask on the Discord Server if you don't know which methods you need to use at the builder.

See Listening to Events

Catch votes with webhooks

You need to catch the votes of your bot with webhooks. We show you how you can receive these

Using integrated webhook webserver

If you want to catch votes with our webhook implementation, you need to follow these steps:

1. Go to dev.discord-botlist.eu and login with you discord account.
2. Click on your bot
3. Scroll down to "Webhook-URL" and paste the following: <ip>:2526/webhook
   • Note: You need to replace <ip> with your IP-Address
4. Add .enableWebhooks(true) to the builder
   • Example

        DblEu api = new DblEu.Builder()
          .setAPIKey("key") //Setting the API Keys
          .setId("id") //Setting the client id
          .enableWebhooks(true) //enable webhooks
          .build(); //Build the object

     See Creating the DblEu-Object

Extra

You can change the url for the webhook with .setWebhookPath()

Example:

DblEu api = new DblEu.Builder()
   .setAPIKey("key") //Setting the API Keys
   .setId("id") //Setting the client id
   .enableWebhooks(true) //enable webhooks
   .setWebhookPath("/hook") //set webhook path
   .build(); //Build the object

See Creating the DblEu-Object

Using your own webserver

If you want to use your own webserver, you can simulate a VoteEvent

Example

DblEu api = ...;
String body = "...";
api.simulateEvent(VoteEvent.class, api.getSimulationBuilder().setBody(body).build()).queue((event) -> {
   System.out.println("Received a vote from " + event.getVote().getVoter().getName() + " (" + event.getVote().getVoter().getId() + ")"); //Printing information
})

See Simulate Events, Listening to events

API Key and ID

The API Key and the ID are required parameter of the library to tell the API who you are.

API Key

Follow these steps to get your bots API Key:

1. Go to dev.discord-botlist.eu and login with you discord account.
2. Click on your bot
3. Scroll down to "API-Key" and click the "Copy"-Button

ID

1. Go to the discord developer portal and go to the setting of your bot.
2. Copy the text under the "APPLICATION ID" headline or click the "Copy" button
