It is a unified API to trigger workflow and doesn’t require user creation before hand to trigger notification. Recommended for platforms transitioning their existing notifications to SuprSend. If you are using our frontend SDKs to configure notifications and passing events and user properties from third-party data platforms like Segment, then event-based trigger would be a better choice.

📘 Available in SDK version >= 1.10.0

​
Payload Schema

Once your request is accepted, you can check the status of your request in the SuprSend Logs.

const { Suprsend, WorkflowTriggerRequest } = require("@suprsend/node-sdk");
const supr_client = new Suprsend("_workspace_key_", "_workspace_secret_");

// Prepare workflow payload
const body = {
   "workflow": "_workflow_slug_",
   "actor": {
      "distinct_id": "0fxxx8f74-xxxx-41c5-8752-xxxcb6911fb08",
      "name": "actor_1",
      "$skip_create": true
   },
   "recipients": [
      // notify user 
      {
         "distinct_id": "0gxxx9f14-xxxx-23c5-1902-xxxcb6912ab09",
         "$email": ["abc@example.com"],
         "name": "recipient_1",
         "$preferred_language": "en",
         "$timezone": "America/New_York",
         "$skip_create": true
      },
      // notify object 
      {
         "object_type": "teams",
         "id": "finance",
         "$skip_create": true
      }
   ],
   "data": {
      "first_name": "User",
      "invoice_amount": "$5000",
      "invoice_id": "Invoice-1234"
   }
};

// Create workflow instance
const w1 = new WorkflowTriggerRequest(body, {
   tenant_id: "tenant_id1",
   idempotency_key: "_unique_identifier_of_the_request_"
});

// Trigger workflow
const response = supr_client.workflows.trigger(w1);
response.then(res => console.log("response", res));

To prevent automatic creation of an actor, or recipient (user/object) in SuprSend (the case where they already exist in your system), you can use the "$skip_create": true flag.

This can be applied inside the actor, individual user recipient objects, or object recipient objects.

PropertyTypeDescription
workflowstringSlug of the designed workflow on the SuprSend dashboard. You’ll get the slug from workflow settings.
recipientsarray of string / array of objectsList of users who need to be notified. You can add up to 100 recipients in a workflow trigger. You can either pass recipients as an array of distinct_ID (if the user is pre-synced in the SuprSend database) or define recipient information inline.
actor (Optional)string / objectIncludes distinct_id and properties of the user who performed the action. You can use it for cross-user notifications where you need to include actor properties in the notification template. Actor properties can be added as $actor.<prop>.
dataobjectVariable data required to render dynamic template content or workflow properties such as dynamic delay or channel override in the send node.
tenant_id (Optional)stringTrigger workflow for a specific tenant/brand.
idempotency_key (Optional)stringUnique identifier of the request. We’ll be returning idempotency_key in our outbound webhook response. You can use it to map notification statuses and replies in your system.
recipients[].$preferred_languagestringTo set the recipient’s preferred language. This is to support localization in notification content. You can pass the language in ISO 639-1 2-letter format. Refer to all language codes here.
recipients[].$timezonestringTo set the recipient’s timezone. Used to send notifications in the user’s local timezone. You can pass the timezone in IANA (TZ identifier) format.

​
Sending notification to multiple users

Recipients in workflow call is an array of distinct_ids or recipient objects. You can pass up to 100 recipients in a single workflow trigger. SuprSend will internally convert it into multiple workflow triggers, one for each recipient in the array.

"recipients": ["distinct_id1","distinct_id2"]

---- OR ------

"recipients": [
  {
    "distinct_id": "id1",
    "$email":["id1@example.com"],
    "name":"recipient_1"
  },
  {
    "distinct_id": "id1",
    "$email":["id2@example.com"],
    "name":"recipient_2"
  }
]

Use lists to broadcast to a large list of users:

We recommend you to use lists and broadcast to send notifications to a user list larger than 1000 users. This approach allows bulk processing, resulting in significantly faster delivery compared to individual workflow calls. Sending individual workflows to a large set of users may introduce delays in your notification queue.

​
Identifying recipients inline

One of the benefits of using direct workflow trigger is that you can identify recipients inline. You can include recipient channel information, their channel preferences, and their user properties along with the workflow trigger. Upon triggering the workflow, the recipient will be automatically created in the SuprSend database in the background. This facilitates dynamic synchronization of your user data within SuprSend and eliminates the need for any migration efforts on your end to start sending notifications from SuprSend. You can also use recipient properties in your template as $recipient.<property>.

This is how the complete recipient object with look like

"recipients": [{
  "distinct_id": "0gxxx9f14-xxxx-23c5-1902-xxxcb6912ab09",
  "$email":["abc@example.com"], // email communication channel
  "$sms":["+15555555555"], // sms communication channel
  "$channels":["email","inbox"],
  "$preferred_language":"en",
  "$timezone": "America/New_York",
  "custom_prop1":"value_1", // custom property
  "custom_prop2": "value_2", // custom property
}]
PropertyTypeDescription
distinct_idstringUnique identifier of the user to be notified.
communication channels ($email, $sms, etc.)array of string / objectsThe communication channel info provided will be updated in the user profile in the background. For this workflow, only the specified channel values for this recipient will be used for sending notifications instead of all channel values present in the user profile.
$channelsarray of stringBy default, notifications will be sent to all channels defined in the workflow delivery nodes. However, if a user has a specific channel preference for a notification (e.g. they only want to receive payment reminders via email), you can include that preference in the workflow payload. This ensures notifications are sent only to the channels specified here. Supported channels: email, sms, whatsapp, androidpush, iospush, slack, webpush, ms_teams.You can always use our in-built preference APIs to maintain user notification preferences. Preferences defined within SuprSend will automatically apply with workflow triggers.
$preferred_languagestringSets the recipient’s preferred language to support localization in notification content. You can pass the language in ISO 639-1 2-letter format. Refer to all language codes here.
$timezonestringSets the recipient’s timezone to send notifications in the user’s local timezone. You can pass the timezone in IANA (TZ identifier) format.
*objectYou can pass other user properties to render dynamic template content. These properties will also be set in the user profile and can be used in the template as $recipient.<property>.

​

"$email":["user@example.com"],

"$whatsapp":["+15555555555"],

"$sms":["+15555555555"],

"$androidpush": [{"token": "__android_push_token__", "provider": "fcm", "device_id": ""}],

  "access_token": "xoxb-XXXXXX"
}] 

// slack channel

  "channel": "CXXXXXXXX",
  "access_token": "xoxb-XXXXXX"
}]

// slack incoming webhook
"$slack": [{
  "incoming_webhook": {
    "url": "https://hooks.slack.com/services/TXXXXXXXXX/BXXXXXXXX/XXXXXXXXXXXXXXXXXXX"
  }
}]

// MS teams user or channel using conversation_id
"$ms_teams": [{
  "tenant_id": "c1981ab2-9aaf-xxxx-xxxx",
  "service_url": "https://smba.trafficmanager.net/amer",
  "conversation_id": "19:c1524d7c-a06f-456f-8abe-xxxx"
}] 

// MS teams user using user_id

}]

// MS teams incoming webhook
"$ms_teams": [{
  "incoming_webhook": {
    "url": "https://wnk1z.webhook.office.com/webhookb2/XXXXXXXXX"
  }
}]

​
Sending cross-user notifications

In scenarios where you need to notify a group of users based on another user’s action, such as sending a notification to the document owner when someone comments on it, you can specify the actor in your workflow call. This allows you to use actor’s name or other properties in your notification template. Actor properties can be included in the template as $actor.<property>.

//handlebar template
Hi {{$recipient.name}}, {{$actor.name}} added {{length comments}} new comments on the {{doc_name}}.

// rendered content with Sample Data
Hi recipient_1, actor_1 added 2 new comments on the annual IT report.

{
  "workflow": "new_comment",
  "actor": {
    "distinct_id": "0fxxx8f74-xxxx-41c5-8752-xxxcb6911fb08",
    "name":"actor_1"
  },
  "recipients": [
    {
      "distinct_id": "0gxxx9f14-xxxx-23c5-1902-xxxcb6912ab09",
      "$email":["abc@example.com"],
      "name":"recipient_1"
    }
  ],
  "data":{
    "doc_name": "annual IT report",
    "date": "2024-01-01",
    "comments":["change the date","rest looks good"]
  }
}

​
Sending notification to anonymous user

You can send notifications to anonymous users by passing "is_transient": true in your recipient object. This approach is recommended for scenarios where you need to send notifications to unregistered users without creating them in the SuprSend platform. The same way, you can pass "is_transient": true in your actor object to use actor properties in template without creating user profile.

const workflow_payload = {
    "workflow": "_workflow_slug_",
    "actor": {
      "is_transient": true, // for anonymous actor
      "name":"actor_1"
    },
    "recipients": [
      {
        "is_transient": true, // for anonymous recipient
        "$email":["abc@example.com"],
        "name":"recipient_1"
      }
    ],
    "data":{
      "first_name": "User",
      "invoice_amount": "$5000",
      "invoice_id":"Invoice-1234"
    }
}

​
Multi-tenant notifications

For cases where you want to send notifications to your enterprise customers end users, pass the tenant_id in your workflow instance. You can use this to dynamically manage tenant level notification customizations. This includes the ability to customize template design or content and route notifications via tenant vendors.

const workflow = new WorkflowTriggerRequest(workflow_body, {tenant_id: "tenant_id1"})

​
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. Idempotency key should be uniquely generated for each request (max 255 characters allowed). Spaces in start and end of the key will be trimmed. Here are some common approaches for generating 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. e.g., 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.
const workflow = new WorkflowTriggerRequest(workflow_body, {idempotency_key: "_unique_request_identifier"})

​
Bulk API for triggering multiple workflows

Bulk API allows you to send multiple workflow requests in a single call. Use .append() and workflows.bulk_trigger_instance() to add however-many-records to call in bulk.

const {Suprsend, WorkflowTriggerRequest} = require("@suprsend/node-sdk");

const supr_client = new Suprsend("_workspace_key_", "_workspace_secret_");

const wf1 = new WorkflowTriggerRequest(wf_body1, {tenant_id: "tenant_id1", idempotency_key: "_unique_identifier_of_the_request_"}) // workflow1 instance
const wf2 = new WorkflowTriggerRequest(body2)  // workflow2 instance

const bulk_ins = supr_client.workflows.bulk_trigger_instance() // create bulk instance

bulk_ins.append(wf1,wf2)  // add workflows instances to bulk instance

const response = bulk_ins.trigger(); // trigger workflows 
response.then(res => console.log("response", res));

​
Add attachment (in email)

To add one or more attachments to a notification (viz. Email), call wf_instance.add_attachment() for each file with local path or remote attachment url. Ensure that file path is valid, and public(for remote url) otherwise it will raise error.

const wf_instance = new WorkflowTriggerRequest(wf_body);

wf_instance.add_attachment("/home/user/billing.pdf");
wf_instance.add_attachment("https://www.adobe.com/sample_file.pdf");

A single workflow instance size (including attachment) must not exceed 100KB (100 x 1024 bytes).

​
Dynamic workflow trigger

You can trigger workflow from node SDK by using supr_client.trigger_workflow method. Import Workflow class before calling this method.
Once your request is accepted, you can check the status of your request in the ’ SuprSend Logs’ section.

const { Workflow } = require("@suprsend/node-sdk")

// Prepare Workflow body
const workflow_body = {
  "name": "workflow_name",
  "template": "template_slug",
  "notification_category": "notification_category", //notification category transactional/promotional/system
  "delay": "time_delay",  // time delay after which the first notification will be sent
  "trigger_at": "date string in ISO 8601", // to trigger scheduled notifications

  "users": [
    {
      "distinct_id": "distinct_id", // unique identifier of the user
      // if $channels is present, communication will be triggered on mentioned channels only.
      // "$channels": ["email"],

      // User communication channel can be added as [optional]:
      // "$email":["user@example.com"],
      // "$whatsapp":["+15555555555"],
      // "$sms":["+15555555555"],

    }
  ],

  // delivery instruction [optional]. how should notifications be sent, and whats the success metric
  "delivery": {
    "smart": <boolean_value>,
    "success": "success_metric",

              },
          }
      }
} 

const wf = new Workflow(workflow_body, {tenant_id="default", idempotency_key="__uniq_request_id__"})
// Trigger workflow
const response = supr_client.trigger_workflow(wf); // returns promise
response.then((res) => console.log("response", res));

For configuring a workflow from backend, you can pass following properties in your method

To find the template slug name on SuprSend platform, click on the clipboard icon on Templates page. Templates > Template Details Page

​
Bulk API for triggering multiple workflows.

Bulk API allows you to send multiple workflow requests in a single call. There isn’t any limit on number-of-records that can be added to bulk_workflows instance. Use .append() on bulk_workflows instance to add however-many-records to call in bulk.

const { Workflow } = require("@suprsend/node-sdk")

const bulk_ins = supr_client.bulk_workflows.new_instance()

// one or more workflow instances
const workflow1 = new Workflow({...}) // body must be a proper workflow request json/dict
const workflow2 = new Workflow({...}) // body must be a proper workflow request json/dict

// --- use .append on bulk instance to add one or more records
bulk_ins.append(workflow1)
bulk_ins.append(workflow2)
// OR
bulk_ins.append(workflow1, workflow2)

// -------
const response = bulk_ins.trigger()
response.then((res) => console.log("response", res));
