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 >= v0.11.0

Payload Schema

from suprsend import Event
from suprsend import WorkflowTriggerRequest

supr_client = Suprsend("_workspace_key_", "_workspace_secret_")

# Prepare workflow payload
w1 = WorkflowTriggerRequest(
    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",
        },
    },
    tenant_id="tenant_id1",
    idempotency_key="_unique_identifier_of_the_request_",
)

# Trigger workflow
response = supr_client.workflows.trigger(w1)
print(response)

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.

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

PropertyTypeDescription
workflowstringSlug of the designed workflow on the SuprSend dashboard. You’ll get the slug from workflow settings.
actor (optional)string / objectIncludes distinct_id and properties of the user who performed the action. Used for cross-user notifications, where you need to include actor properties in the notification template. Actor properties can be added as $actor.<prop>.
recipientsarray of string / array of objectsList of users who need to be notified. You can add up to 100 recipients in a workflow trigger. Recipients can be passed as an array of distinct_ID (if the user is pre-synced in the SuprSend database) or defined inline.
dataobjectVariable data required to render dynamic template content or workflow properties such as dynamic delay or channel override in the send node.
tenant_idstringUnique identifier of the brand / tenant.
idempotency_keystringUnique identifier of the request. It will be returned in the outbound webhook response. You can use it to map notification statuses and replies in your system.
recipients[].$timezonestringUsed to set the recipient’s timezone. Allows sending notifications in the user’s local timezone. Pass the timezone in IANA (TZ identifier) format.
recipients[].$preferred_languagestringUsed to set the recipient’s preferred language.

​
Sending notification to multiple recipients

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

---- OR ------
"recipients": ["id1","id2"]

📘Use lists to broadcast to a large list of users:

We recommend you to use lists and broadcasts to send notifications to a user list larger than 1000 users. This approach allows for bulk processing within SuprSend, 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 and is not an optimized way of handling bulk trigger.

​
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

{
  "distinct_id": "0gxxx9f14-xxxx-23c5-1902-xxxcb6912ab09",
  "$email":["abc@example.com"],
  "$channels":["email","inbox"],
  "user_prop1":"value_1",
  "$preferred_language":"en",
  "$timezone": "America/New_York"
}
PropertyTypeDescription
distinct_idstringUnique identifier of the user to be notified.
$<channel> (e.g. $sms)array of string / objectsYou can pass user channel information using $<channel> key. The channel info will be updated in the user profile in the background. For this workflow, only channel values specified in this key will be used for sending notifications (instead of all channel values present in the user profile). Refer to how different communication channels can be passed here.
$channelsarray of stringUse it to pass the user’s channel preference in the payload. You can always use our in-built preference APIs to maintain user notification preferences. Preferences defined within SuprSend will automatically apply with the workflow trigger. By default, notifications will be sent to all channels defined in the workflow delivery node. However, if the user has a specific channel preference for a notification (e.g. only wants 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 in the $channels key. Supported channel values: email, sms, whatsapp, androidpush, iospush, slack, webpush, ms_teams.
$preferred_languagestringTo set the recipient’s preferred language. This supports localization in notification content. Pass the language in ISO 639-1 2-letter format. Refer to all language codes here.
$timezonestringTo set the recipient’s timezone. Used to send notifications in the user’s local timezone. Pass the timezone in IANA (TZ identifier) format.
*key-value pairYou can pass other user properties to render dynamic template content in key-value pairs like "user_prop1": "value1". Extra properties will be set in the subscriber profile (as subscriber properties), which can then be used in the template as $recipient.<property>.

​
Add user communication channel

"$email":["user@example.com"],
"$whatsapp":["+15555555555"],
"$sms":["+15555555555"],
"$androidpush": [{"token": "__android_push_token__", "provider": "fcm", "device_id": ""}],
"$iospush":[{"token": "__ios_push_token__", "provider": "apns", "device_id": ""}],
"$slack": [{
  "email": "user@example.com",
  "access_token": "xoxb-XXXXXXXX"
}]   // slack using email

"$slack": [{
  "user_id": "U/WXXXXXXXX",
  "access_token": "xoxb-XXXXXX"
}] // slack using member_id

"$slack": [{
  "channel": "CXXXXXXXX",
  "access_token": "xoxb-XXXXXX"
}] // slack channel

"$slack": [{
  "incoming_webhook": {
    "url": "https://hooks.slack.com/services/TXXXX/BXXXX/XXXXXXX"
  }
}] // slack incoming webhook

"$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 or channel using conversation_id

"$ms_teams": [{
  "tenant_id": "c1981ab2-9aaf-xxxx-xxxx",
  "service_url": "https://smba.trafficmanager.net/amer",
  "user_id": "29:1nsLcmJ2RKtYH6Cxxxx-xxxx"
}] // MS teams user using user_id

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

​
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>.

Sample template with actor and recipient properties:

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

//Rendered content
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.

from suprsend import Event
from suprsend import WorkflowTriggerRequest

supr_client = Suprsend("_workspace_key_", "_workspace_secret_")

# Prepare workflow payload
w1 = WorkflowTriggerRequest(
  body={
    "workflow": "_workflow_slug_",
    "actor": {
      "is_transient": True,
      "name":"actor_1"
    },
    "recipients": [
      {
        "is_transient": True,
        "$email":["abc@example.com"],
        "name":"recipient_1"
      }
    ],
    "data":{
      "first_name": "User",
      "invoice_amount": "$5000",
      "invoice_id":"Invoice-1234"
    }
  },
  tenant_id = "tenant_id1",
  idempotency_key = "_unique_identifier_of_the_request_"
)

# Trigger workflow
response = supr_client.workflows.trigger(w1)
print(response)

​
Multi-tenant notifications

For use 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.

from suprsend import Event
from suprsend import WorkflowTriggerRequest

supr_client = Suprsend("_workspace_key_", "_workspace_secret_")

# Prepare workflow payload
w1 = WorkflowTriggerRequest(
  body={...},
  tenant_id = "tenant_id1",
  idempotency_key = "_unique_identifier_of_the_request_"
)

# Trigger workflow
response = supr_client.workflows.trigger(w1)
print(response)

​
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.

​
Bulk trigger 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 workflows.bulk_trigger_instance() instance to add however-many-records to call in bulk.

from suprsend import Event
from suprsend import WorkflowTriggerRequest

supr_client = Suprsend("_workspace_key_", "_workspace_secret_")

# Workflow: 1
w1 = WorkflowTriggerRequest(
  body={...},
  tenant_id = "tenant_id1",
  idempotency_key = "_unique_identifier_of_the_request_"
)

# Workflow: 2
w2 = WorkflowTriggerRequest(
  body={...}
)
# ...... Add as many Workflow records as required.

bulk_ins = supr_client.workflows.bulk_trigger_instance()

bulk_ins.append(w1,w2)

# Trigger workflow
response = bulk_ins.trigger()
print(response)

​
Add file 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. Ensure that file_path is proper, otherwise it will raise FileNotFoundError.

from suprsend import Workflow

workflow_body = {...}
wf_instance = Workflow(body=workflow_body)

# this snippet can be used to add attachment to workflow
file_path = "/home/user/billing.pdf"
wf_instance.add_attachment(file_path)

A single workflow body size (including attachment) must not exceed 800KB (800 x 1024 bytes).

​
Dynamic workflow trigger

You can trigger workflow from python SDK using supr_client.trigger_workflow method.

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 workflow happens asynchronously.

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

from suprsend import Workflow

​
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.

from suprsend import Workflow

bulk_ins = supr_client.bulk_workflows.new_instance()

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

# -------
response = bulk_ins.trigger()

print(response)
