Send and Track events using Java SDK
Open Recipe

Pre-requisites

  1. Integrate Java SDK
  2. Create User Profile
  3. Create Template on SuprSend platform - if you want to trigger workflow by passing the event
  4. Create Workflow on SuprSend Platform - if you want to trigger workflow by passing the event

Create Workflow on SuprSend Platform

For Event based workflow trigger, you'll have to create the workflow on SuprSend Platform. Once the workflow is created, you can pass the EventName ( GROCERY_PURCHASED in below example) defined in workflow configuration with the help of suprClient.TrackEvent method. Variables added in the template should be passed as event Properties

Send Event

You can send event to Suprsend platform by using the suprClient.trackEvent method.

Method:

import org.json.JSONObject;

import suprsend.Suprsend;
import suprsend.Event;

public class Event {
  public static void main(String[] args) throws Exception {
    trackEvent();
  }
  
  private static Subscriber trackEvent() throws SuprsendException {
		Suprsend suprsendClient = new Suprsend("_workspace_key_", "_workspace_secret_");

    String distinctId = "__distinct_id__"; // Mandatory, Unique id of user in your application
    String eventName = "__event_name__"; // Mandatory, name of the event you're tracking
    
    // Properties:  Optional, default=None, a dict representing event-attributes
    JSONObject eventProps = new JSONObject()
        .put("key1", "value1")
      	.put("key2", "value2");
    
    Event e = new Event(distinctId, eventName, eventProps);
    
    // Track event
		JSONObject response = suprClient.trackEvent(e);
		System.out.println(response);
	}

ParameterDescriptionFormatObligation
distinct_iddistinct_id of subscriber performing the eventint, bigint, string, UUIDmandatory
event_namestring identifier for the event like product_purchasedstringmandatory
propertiesa dictionary representing event attributes like first_name
Event properties can be used to pass template variables in case of event based trigger		Dictionaryoptional

❗️

Event naming guidelines

When you create an Event or a property, please ensure that the Event Name or Property Name does not start with $ or ss_, as we have reserved these symbols for our internal events and property names.


Sample code

import org.json.JSONObject;

import suprsend.Suprsend;
import suprsend.Event;

public class Event {
  public static void main(String[] args) throws Exception {
    trackEvent();
  }
  
  private static Subscriber trackEvent() throws SuprsendException {
		Suprsend suprsendClient = new Suprsend("_workspace_key_", "_workspace_secret_");

    String distinctId = "0fxxx8f74-xxxx-41c5-8752-xxxcb6911fb08"; // Mandatory, Unique id of user in your application
    String eventName = "product_purchased"; // Mandatory, name of the event you're tracking
    
    // Properties:  Optional, default=None, a dict representing event-attributes
    JSONObject eventProps = new JSONObject()
        .put("first_name", "User")
      	.put("spend_amount", "$10");
   		  .put("nested_key_example", new JSONObject().put("nested_key1", "some_value_1"))
    
    
    Event e = new Event(distinctId, eventName, eventProps);
    
    // Track event
		JSONObject response = suprClient.trackEvent(e);
		System.out.println(response);
	}

🚧

Note

  • Event_name in Track event method should exactly match the Event name added in Workflow configurations
  • Only one distinct_id can be added at a time in Track event method

Trigger events for custom brand

If you handle communications to end users on behalf of your customers and want to send custom notifications for each brand, you can do that with the help of brands.

Just pass the brand_id of your customer brand as 5th parameter in your event instance like shown below and the properties of that brand will be used to replace brand variables in your template.

...
Event e = new Event(distinctId, eventName, eventProps, , brandId);
...

Idempotent Requests

SuprSend supports idempotency to ensure that requests can be retried safely without duplicate processing. If Suprsend receives and processes a request with an idempotency_key, it will skip processing requests with same idempotency_key for next 24 hours. You can use this key to track webhooks related to workflow notifications.

To make an idempotent request, pass idempotency_key as the 4th parameter in your event instance like shown below. Idempotency key should be unique that you generate for each request. You may use any string up to 255 characters in length as an idempotency key. Ensure that you don’t add any space in start and end of the key as it will be trimmed.

...
Event e = new Event(distinctId, eventName, eventProps, idempotencyKey);
...

Here are some common approaches for assigning idempotency keys:

  • Generate a random UUID for each request.
  • Construct the idempotency key by combining relevant information about the request. This can include parameters, identifiers, or specific contextual details that are meaningful within your application. For example, you could concatenate the user ID, action, and timestamp to form an idempotency key like user147-new-comment-1687437670
  • Request-specific Identifier: If your request already contains a unique identifier, such as an order ID or a job ID, you can use that identifier directly as the idempotency key.

Add file attachment in event (for email)

To add one or more Attachments to a Notification (viz. Email), you can just append the filepath of attachment to the event instance.

  • Call event.addAttachment() for each file with an accessible URL.
  • Ensure that file_path is a publicly accessible URL. Since event API size can't be > 100 KB, local file paths can't be passed in event attachment.

Refer below example for adding attachment in event call

import org.json.JSONObject;

import suprsend.Suprsend;
import suprsend.Event;

public class Event {
  public static void main(String[] args) throws Exception {
    trackEvent();
  }
  
  private static Subscriber trackEvent() throws SuprsendException {
		Suprsend suprsendClient = new Suprsend("_workspace_key_", "_workspace_secret_");

    String distinctId = "0fxxx8f74-xxxx-41c5-8752-xxxcb6911fb08"; // Mandatory, Unique id of user in your application
    String eventName = "product_purchased"; // Mandatory, name of the event you're tracking
    
    // Properties:  Optional, default=None, a dict representing event-attributes
    JSONObject eventProps = new JSONObject()
    
    Event e = new Event(distinctId, eventName, eventProps);
    String filePath = "https://www.africau.edu/images/default/sample.pdf";
    e.addAttachment(filePath);
    
    // Track event
		JSONObject response = suprClient.trackEvent(e);
		System.out.println(response);
	}

🚧

Add Publicly accessible URL in attachment

Please add public accessible URL only as attachment file otherwise it will throw an error 404 not found and workflow will not be triggered


Response

When you call suprClient.trackEvent, the SDK internally makes an HTTP call to SuprSend Platform to register this request, and you'll immediately receive a response indicating the acceptance status.

Note: The actual processing/execution of event happens asynchronously.

// Response structure
{
    "success": true, // if true, request was accepted.
    "status": "success",
    "status_code": 202, // http status code
    "message": "OK",
}

{
    "success": false, // error will be present in message
    "status": "fail",
    "status_code": 500, // http status code
    "message": "error message",
}

Bulk API for multiple event requests

You can use Bulk API to send multiple events.

Use .append() on bulk_events instance to add however-many-records to call in bulk.

import org.json.JSONObject;

import suprsend.Suprsend;
import suprsend.Event;

public class Event {
  public static void main(String[] args) throws Exception {
    trackEvent();
  }
  
  private static Subscriber trackEvent() throws SuprsendException {
		Suprsend suprsendClient = new Suprsend("_workspace_key_", "_workspace_secret_");
    
    BulkEvents bulkIns = suprClient.bulkEvents.newInstance();
    
    Event e1 = new Event(distinctId1, eventName1, eventProps1); //Event 1
    Event e2 = new Event(distinctId2, eventName2, eventProps2); //Event 2
    
    // --- use .append on bulk instance to add one or more records
      bulkIns.append(e1)
      bulkIns.append(e2)
    // OR
      bulkIns.append(e1, e2)
    
    // Track event
		JSONObject response = bulkIns.trigger();
		System.out.println(response);
	}

🚧

Bulk API supported in SDK version 0.5.0 and above

Bulk API is supported in SuprSend java-sdk version 0.5.0 and above. If you are using an older version, please upgrade to the latest SDK version.


How SuprSend Processes the bulk API request

  • On calling bulkIns.trigger(), the SDK internally makes one-or-more Callable-chunks.
  • Each callable-chunk contains a subset of records, the subset calculation is based on each record's bytes-size and max allowed chunk-size, chunk-length etc.
  • For each callable-chunk SDK makes an HTTP call to SuprSend to register the request.

Add file attachment in bulk API (for email)

Similar to single API call, you can add file attachment to bulk API by appending the attachment filepath to each event instance in bulk API call.

  • Call event.addAttachment() for each file with an accessible URL. Ensure that file_path is a publicly accessible URL.
  • Since event API size can't be > 100 KB, local file paths can't be passed in event attachment.

Refer below example for adding attachment in bulk API call

import org.json.JSONObject;

import suprsend.Suprsend;
import suprsend.Event;

public class Event {
  public static void main(String[] args) throws Exception {
    trackEvent();
  }
  
  private static Subscriber trackEvent() throws SuprsendException {
		Suprsend suprsendClient = new Suprsend("_workspace_key_", "_workspace_secret_");

    BulkEvents bulkIns = suprClient.bulkEvents.newInstance();
    
    Event e1 = new Event(distinctId1, eventName1, eventProps1); //Event 1
    // this snippet can be used to add attachment to event
    String filePath1 = "https://www.africau.edu/images/default/sample.pdf";
    e1.addAttachment(filePath1);
    
    Event e2 = new Event(distinctId2, eventName2, eventProps2); //Event 2
    String filePath2 = "https://www.adobe.com/sample_file.pdf";
    e1.addAttachment(filePath2);
    
    // --- use .append on bulk instance to add one or more records
      bulkIns.append(e1)
      bulkIns.append(e2)
    // OR
      bulkIns.append(e1, e2)
    
    
    // Track event
		JSONObject response = bulkIns.trigger();
		System.out.println(response);
	}
