suprsend-py-sdk 0.3.0

Suprsend library for Python

suprsend-py-sdk

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

We're working towards creating SDK in other languages as well.

SuprSend SDKs available in following languages

• python3 >= 3.7 (suprsend-py-sdk)
• node (suprsend-node-sdk)
• java (suprsend-java-sdk)

Installation

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

pip install suprsend-py-sdk

This SDK depends on a system package called libmagic. You can install it as follows:

# On debian based systems
sudo apt install libmagic

# 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 notification to a user with id: distinct_id, email: [e-mail] & androidpush(fcm-token): __android_push_fcm_token__ using template purchase-made and notification_category system

from suprsend import Workflow
# Prepare Workflow body
workflow_body = {
    "name": "Purchase Workflow",
    "template": "purchase-made",
    "notification_category": "system",
    # "delay": "15m",  # Check duration format below
    "users": [
        {
          "distinct_id": "0f988f74-6982-41c5-8752-facb6911fb08",
          # if $channels is present, communication will be tried on mentioned channels only.
          # "$channels": ["email"],
          "$email": ["[e-mail]"],
          "$androidpush": [{"token": "__android_push_token__", "provider": "fcm", "device_id": ""}],
        }
    ],
    # delivery instruction. how should notifications be sent, and whats the success metric
    "delivery": {
        "smart": False,
        "success": "seen"
    },
    # 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 = Workflow(body=workflow_body)
# Trigger workflow
response = supr_client.trigger_workflow(wf)
print(response)

When you call supr_client.trigger_workflow, 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 Workflow

workflow_body = {...}
wf = Workflow(body=workflow_body, idempotency_key="__uniq_request_id__")
# Trigger workflow
response = supr_client.trigger_workflow(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",
}

Duration Format

format for specifying duration: [xx]d[xx]h[xx]m[xx]s Where

• d stands for days. value boundary: 0 <= d
• h stands for hours. value boundary: 0 <= h <= 23
• m stands for minutes. value boundary: 0 <= m <= 59
• s stands for seconds. value boundary: 0 <= s <= 59

Examples:

• 2 days, 3 hours, 12 minutes, 23 seconds -> 2d3h12m23s or 02d03h12m23s
• 48 hours -> 2d
• 30 hours -> 1d6h
• 300 seconds -> 5m
• 320 seconds -> 5m20s
• 60 seconds -> 1m

Delivery instruction

All delivery options:

delivery = {
    "smart": True/False,
    "success": "seen/interaction/<some-user-defined-success-event>",
    "time_to_live": "<TTL duration>",
    "mandatory_channels": [] # list of mandatory channels e.g ["email"]
}

Where

• smart (boolean) - whether to optimize for number of notifications sent?

  • Possible values: True / False
  • Default value: False
  • If False, then notifications are sent on all channels at once.
  • If True, then notifications are sent one-by-one (on regular interval controlled by time_to_live) on each channel until given success-metric is achieved.

• success - what is your measurement of success for this notification?

  • Possible values: seen / interaction / <some-user-defined-success-event>
  • Default value: seen
  • If seen: If notification on any of the channels is seen by user, consider it a success.
  • If interaction: If notification on any of the channels is clicked/interacted by the user, consider it a success.
  • If <some-user-defined-success-event>: If certain event is done by user within the event-window (1 day), consider it a success.
    • currently, event-window is not configurable. default set to 1d (1 day). success-event must happen within this event-window since notification was sent.

• time_to_live - What's your buffer-window for sending notification.

  • applicable when smart=True, otherwise ignored
  • Default value: 1h (1 hour)
  • notification on each channel will be sent with time-interval of [time_to_live / (number_of_valid_channels - 1))] apart.
  • Currently, channels are tried in low-to-high notification-cost order based on Notification Cost mentioned in Vendor Config. If cost is not mentioned, it is considered 0 for order-calculation purpose.
  • Process will continue until all channels are exhausted or success metric is achieved, whichever occurs first.

• mandatory_channels - Channels on which notification has to be sent immediately (irrespective of notification-cost).

  • applicable when smart=True, otherwise ignored
  • Default value: [] (empty list)
  • possible channels: email, sms, whatsapp, androidpush, iospush etc.

If delivery instruction is not provided, then default value is

{
    "smart": False,
    "success": "seen"
}

Add attachments

To add one or more Attachments to a Workflow/Notification (viz. Email), call Workflow.add_attachment(file_path) 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)

Attachment structure

The add_attachment(...) call appends below structure to workflow_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). While calculating size, attachments are ignored
• 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 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)

• 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("[e-mail]") # - To add Email

user.add_sms("[phone]") # - To add SMS

user.add_whatsapp("[phone]") # - 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("[e-mail]")  # - To add Slack using email
user.add_slack_userid("U03XXXXXXXX")  # - To add Slack if slack member_id is known

# 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("[e-mail]")
user.remove_sms("[phone]")
user.remove_whatsapp("[phone]")
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("[e-mail]")
user.remove_slack_userid("U03XXXXXXXX")

# 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

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

• Note: After calling add_*/remove_*/unset 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 Workflow

# Prepare Workflow body
workflow_body = {
    "name": "Purchase Workflow",
    "template": "purchase-made",
    "notification_category": "system",
    # "delay": "15m",
    "users": [
        {
            "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 = Workflow(body=workflow_body)
# Trigger workflow
response = supr_client.trigger_workflow(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("[e-mail]")

u2 = supr_client.user.get_instance("distinct_id_2") # User 2
u2.set_email("[e-mail]")

# --- 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__")
# 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)
