suprsend-py-sdk

This package can be included in a python3 project to easily integrate with SuprSend platform.

Installation

suprsend-py-sdk is available on PyPI. You can install using pip.

pip install suprsend-py-sdk

Optional: Better attachment MIME type detection

When adding file attachments, the SDK needs to detect the file's MIME type (e.g. application/pdf, image/png). By default, it uses Python's built-in mimetypes module, which guesses based on the file extension.

For more accurate detection based on actual file content, install with the magic extra:

pip install suprsend-py-sdk[magic]

This requires the libmagic system library:

# On debian based systems
sudo apt install libmagic1

# If you are using macOS
brew install libmagic

Usage

Initialize the SuprSend SDK

from suprsend import Suprsend
# Initialize SDK
supr_client = Suprsend("workspace_key", "workspace_secret")

Following example shows a sample request for triggering a workflow. It triggers a pre-created workflow purchase-made to a recipient with id: distinct_id, email: user@example.com & androidpush(fcm-token): __android_push_fcm_token__

from suprsend import WorkflowTriggerRequest
# Prepare Workflow body
wf = WorkflowTriggerRequest(
  body={
    "workflow": "purchase-made",
    "recipients": [
        {
          "distinct_id": "0f988f74-6982-41c5-8752-facb6911fb08",
          # if $channels is present, communication will be tried on mentioned channels only (for this request).
          # "$channels": ["email"],
          "$email": ["user@example.com"],
          "$androidpush": [{"token": "__android_push_token__", "provider": "fcm", "device_id": ""}],
        }
    ],
    # data can be any json / serializable python-dictionary
    "data": {
        "first_name": "User",
        "spend_amount": "$10",
        "nested_key_example": {
            "nested_key1": "some_value_1",
            "nested_key2": {
              "nested_key3": "some_value_3",
            },
        }
    }
  }
)
# Trigger workflow
response = supr_client.workflows.trigger(wf)
print(response)

When you call supr_client.workflows.trigger, 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.

You can also pass idempotency-key while triggering a workflow. Maximum length of idempotency_key can be 64 chars. idempotency_key has multiple uses e.g.

1. Avoid duplicate request. If Suprsend receives and processes a request with an idempotency_key, it will skip processing requests with same idempotency_key for next 24 hours.
2. You can use this key to track webhooks related to workflow notifications.

from suprsend import WorkflowTriggerRequest

workflow_body = {...}
wf = WorkflowTriggerRequest(body=workflow_body, idempotency_key="__uniq_request_id__")
# You can also pass the tenant_id on behalf of which the workflow is to run.
wf = WorkflowTriggerRequest(body=workflow_body, idempotency_key="__uniq_request_id__", tenant_id="default")
# Trigger workflow
response = supr_client.workflows.trigger(wf)
print(response)

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

# If the call succeeds, response will looks like:
{
    "success": True,
    "status": "success",
    "status_code": 202,
    "message": "Message received",
}

# In case the call fails. You will receive a response with success=False
{
    "success": False,
    "status": "fail",
    "status_code": 400/500,
    "message": "error message",
}

Add attachments

To add one or more Attachments to a Workflow/Notification (viz. Email), call WorkflowTriggerRequest.add_attachment(file_path). If providing a local path, ensure that it is proper, otherwise it will raise FileNotFoundError.

from suprsend import WorkflowTriggerRequest
workflow_body = {...}
wf_instance = WorkflowTriggerRequest(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)

Attachment structure

The add_attachment(...) call appends below structure to body->data->'$attachments'

{
    "filename": "billing.pdf",
    "contentType": "application/pdf",
    "data": "Q29uZ3JhdHVsYXRpb25zLCB5b3UgY2FuIGJhc2U2NCBkZWNvZGUh",
}

Where

• filename - name of file.
• contentType - MIME-type of file content.
• data - base64-encoded content of file.

Limitation

• a single workflow body size must not exceed 800KB (800 * 1024 bytes).
• if size exceeds above mentioned limit, SDK raises python's builtin ValueError.

Bulk API for Workflow Requests

You can send bulk request for workflows in one call. Use .append() on bulk_workflows instance to add however-many-records to call in bulk.

from suprsend import WorkflowTriggerRequest

bulk_ins = supr_client.workflows.bulk_trigger_instance()

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

• There isn't any limit on number-of-records that can be added to bulk_workflows instance.
• On calling bulk_ins.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 and chunk-length etc.
• for each callable-chunk SDK makes an HTTP call to SuprSend To register the request.

Set channels in User Profile

If you regularly trigger a workflow for users on some pre-decided channels, then instead of adding user-channel-details in each workflow request, you can set those channel-details in user profile once, and after that, in workflow trigger request you only need to pass the distinct_id of the user. All associated channels in User profile will be automatically picked when executing the workflow.

• First Instantiate a user object

distinct_id = "__uniq_user_id__"  # Unique id of user in your application
# Instantiate User profile
user = supr_client.user.get_instance(distinct_id=distinct_id)

• To add channel details to this user (viz. email, sms, whatsapp, androidpush, iospush etc) use user.add_* method(s) as shown in the example below.

# Add channel details to user-instance. Call relevant add_* methods

user.add_email("user@example.com") # - To add Email

user.add_sms("+919999999999") # - To add SMS

user.add_whatsapp("+919999999999") # - To add Whatsapp

user.add_androidpush("__android_push_fcm_token__") # - by default, token is assumed to be fcm-token

# You can set the optional provider value [fcm/xiaomi/oppo] if its not a fcm-token
user.add_androidpush("__android_push_xiaomi_token__", provider="xiaomi")

user.add_iospush("__iospush_token__")

user.add_slack({"email": "user@example.com", "access_token": "xoxb-XXXXXXXXXXXX"})  # - DM user using email
user.add_slack({"user_id": "U03XXXXXXXX", "access_token": "xoxb-XXXXXXXXXXXX"})  # - DM user using slack member_id if known
user.add_slack({"channel_id": "C03XXXXXXXX", "access_token": "xoxb-XXXXXXXXXXXX"})  # - Use channel id
user.add_slack({"incoming_webhook": {"url": "https://hooks.slack.com/services/TXXXXXXXXX/BXXXXXX/XXXXXXX"}})  # - Use incoming webhook

user.add_ms_teams({"tenant_id": "XXXXXXX", "service_url": "https://smba.trafficmanager.net/XXXXXXXXXX", "conversation_id": "XXXXXXXXXXXX"})  # - DM on Team's channel using conversation id
user.add_ms_teams({"tenant_id": "XXXXXXX", "service_url": "https://smba.trafficmanager.net/XXXXXXXXXX", "user_id": "XXXXXXXXXXXX"})  # - DM user using team user id
user.add_ms_teams({"incoming_webhook": {"url": "https://XXXXX.webhook.office.com/webhookb2/XXXXXXXXXX@XXXXXXXXXX/IncomingWebhook/XXXXXXXXXX/XXXXXXXXXX"}})  # - Use incoming webhook

# After setting the channel details on user-instance, call save()
response = user.save()
print(response)

# 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",
}

• Similarly, If you want to remove certain channel details from user, you can call user.remove_* method as shown in the example below.

# Remove channel helper methods
user.remove_email("user@example.com")
user.remove_sms("+919999999999")
user.remove_whatsapp("+919999999999")
user.remove_androidpush("__android_push_fcm_token__")
user.remove_androidpush("__android_push_xiaomi_token__", provider="xiaomi")
user.remove_iospush("__iospush_token__")

user.remove_slack({"email": "user@example.com", "access_token": "xoxb-XXXXXXXXXXXX"})  # - DM user using email
user.remove_slack({"user_id": "U03XXXXXXXX", "access_token": "xoxb-XXXXXXXXXXXX"})  # - DM user using slack member_id if known
user.remove_slack({"channel_id": "C03XXXXXXXX", "access_token": "xoxb-XXXXXXXXXXXX"})  # - Use channel id
user.remove_slack({"incoming_webhook": {"url": "https://hooks.slack.com/services/TXXXXXXXXX/BXXXXXX/XXXXXXX"}})  # - Use incoming webhook

user.remove_ms_teams({"tenant_id": "XXXXXXX", "service_url": "https://smba.trafficmanager.net/XXXXXXXXXX", "conversation_id": "XXXXXXXXXXXX"})  # - DM on Team's channel using conversation id
user.remove_ms_teams({"tenant_id": "XXXXXXX", "service_url": "https://smba.trafficmanager.net/XXXXXXXXXX", "user_id": "XXXXXXXXXXXX"})  # - DM user using team user id
user.remove_ms_teams({"incoming_webhook": {"url": "https://XXXXX.webhook.office.com/webhookb2/XXXXXXXXXX@XXXXXXXXXX/IncomingWebhook/XXXXXXXXXX/XXXXXXXXXX"}})  # - Use incoming webhook

# save
response = user.save()
print(response)

• If you need to delete/unset all emails (or any other channel) of a user, you can call unset method on the user instance. The method accepts the channel key/s (a single key or list of keys)

# --- To delete all emails associated with user
user.unset("$email")
response = user.save()
print(response)

# what value to pass to unset channels
# for email:                $email
# for whatsapp:             $whatsapp
# for SMS:                  $sms
# for androidpush tokens:   $androidpush
# for iospush tokens:       $iospush
# for webpush tokens:       $webpush
# for slack:                $slack
# for ms_teams:             $ms_teams

# --- multiple channels can also be deleted in one call by passing argument as a list
user.unset(["$email", "$sms", "$whatsapp"])
user.save()

• You can also set preferred language of user using set_preferred_language(lang_code). Value for lang_code must be 2-letter code in the ISO 639-1 Alpha-2 code format. e.g. en (for English), es (for Spanish), fr (for French) etc.

# --- Set 2-letter language code in "ISO 639-1 Alpha-2" format
user.set_preferred_language("en")
response = user.save()
print(response)

• You can also set timezone of user using set_timezone(timezone). Value for timezone must be from amongst the IANA timezones as maintained in the latest release here: https://data.iana.org/time-zones/tzdb-2024a/zonenow.tab.

# --- Set timezone property at user level in IANA timezone format
user.set_timezone("America/Los_Angeles")
response = user.save()
print(response)

• Note: After calling add_*/remove_*/unset/set_* methods, don't forget to call user.save(). On call of save(), SDK sends the request to SuprSend platform to update the User-Profile.

Once channels details are set at User profile, you only have to mention the user's distinct_id while triggering workflow. Associated channels will automatically be picked up from user-profile while processing the workflow. In the example below, we are passing only distinct_id of the user:

from suprsend import WorkflowTriggerRequest

# Prepare Workflow body
request_body = {
    "workflow": "purchase-made",
    "recipients": [
        {
            "distinct_id": "0f988f74-6982-41c5-8752-facb6911fb08",
        }
    ],
    # data can be any json / serializable python-dictionary
    "data": {
        "first_name": "User",
        "spend_amount": "$10",
        "nested_key_example": {
            "nested_key1": "some_value_1",
            "nested_key2": {
              "nested_key3": "some_value_3",
            },
        }
    }
}
wf = WorkflowTriggerRequest(body=request_body)
# Trigger workflow
response = supr_client.workflows.trigger(wf)
print(response)

Bulk API for Users

You can send multiple subscriber requests in one call. Use .append() on bulk_users instance to add however-many-records to call in bulk.

bulk_ins = supr_client.bulk_users.new_instance()
# Prepare multiple users
u1 = supr_client.user.get_instance("distinct_id_1") # User 1
u1.set_email("u1@example.com")

u2 = supr_client.user.get_instance("distinct_id_2") # User 2
u2.set_email("u2@example.com")

# --- use .append on bulk instance to add one or more records
bulk_ins.append(u1)
bulk_ins.append(u2)
# OR
bulk_ins.append(u1, u2)

# -------
response = bulk_ins.save()
print(response)

Track and Send Event

You can track and send events to SuprSend platform by using supr_client.track_event method. An event is composed of an event_name, tracked wrt a user: distinct_id, with event-attributes: properties

from suprsend import Event

# Example
distinct_id = "__uniq_user_id__" # Mandatory, Unique id of user in your application
event_name = "__event_name__"   # Mandatory, name of the event you're tracking
properties = {} # Optional, default=None, a dict representing event-attributes

event = Event(distinct_id=distinct_id, event_name=event_name, properties=properties)
# You can also add Idempotency-key
event = Event(distinct_id=distinct_id, event_name=event_name, properties=properties,
              idempotency_key="__uniq_request_id__")
# You can also pass the tenant_id to be used for templates/notifications
event = Event(distinct_id=distinct_id, event_name=event_name, properties=properties,
              idempotency_key="__uniq_request_id__", tenant_id="default")
# Send event
response = supr_client.track_event(event)
print(response)

# 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 events

You can send multiple events in one call. Use .append() on bulk_events instance to add however-many-records to call in bulk.

from suprsend import Event

bulk_ins = supr_client.bulk_events.new_instance()
# Example
e1 = Event("distinct_id1", "event_name1", {"k1": "v1"}) # Event 1
e2 = Event("distinct_id2", "event_name2", {"k2": "v2"}) # Event 2

# --- use .append on bulk instance to add one or more records
bulk_ins.append(e1)
bulk_ins.append(e2)
# OR
bulk_ins.append(e1, e2)

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

Messages API

Bulk Update Message Status

Update the status of one or more messages in a single call. Valid actions: seen, clicked, dismissed, read, unread, archived, unarchived.

messages = [
    {"message_id": "__message_id_1__", "action": "read"},
    {"message_id": "__message_id_2__", "action": "archived"},
]
response = supr_client.messages.bulk_update(messages)
print(response)

# Response structure — 202 Accepted
# Per-record result; check status_code per message_id
