Setting up
To get started using this package, you will need TOKEN and TEST WHATSAPP NUMBER which you can get by from Facebook Developer Portal
Here are steps to follow for you to get started
- Go to your apps
- create an app
- Select Business >> Business
- It will prompt you to enter basic app informations
- It will ask you to add products to your app a. Add WhatsApp Messenger
- Right there you will see a your TOKEN and TEST WHATSAPP NUMBER and its phone_number_id
- Lastly verify the number you will be using for testing on the To field.
Once you're follow the above procedures, now you're ready to start hacking with the Wrapper.
Authentication
Here how you authenticate your application, you need to specify two things the TOKEN
and phone_number_id
of your test number
>>> from heyoo import WhatsApp
>>> messenger = WhatsApp('TOKEN', phone_number_id='104xxxxxx')
Once you have authenticated your app, now you can start using the above mentioned feature as shown above;
Apparently it is only possible to send messages other than templates after the target phone responds to an initial message. Reference: https://developers.facebook.com/community/threads/425605939396247/
Sending Messanges
Use this method to send text message to a WhatsApp number.
>>> messenger.send_message('Your message ', 'Mobile eg: 255757xxxxx')
Sending Images
When sending media(image, video, audio, gif and document ), you can either specify a link containing the media or specify object id, you can do this using the same method.
By default all media methods assume you're sending link containing media but you can change this by specifying the link=False
.
Here an example;
>>> messenger.send_image(
image="https://i.imgur.com/Fh7XVYY.jpeg",
recipient_id="255757xxxxxx",
)
Sending Video
Here an example;
>>> messenger.send_video(
video="https://www.youtube.com/watch?v=K4TOrB7at0Y",
recipient_id="255757xxxxxx",
)
Sending Audio
Here an example;
>>> messenger.send_audio(
audio="https://www.soundhelix.com/examples/mp3/SoundHelix-Song-1.mp3",
recipient_id="255757xxxxxx",
)
Sending Document
Here an example;
>>> messenger.send_document(
document="http://www.africau.edu/images/default/sample.pdf",
recipient_id="255757xxxxxx",
)
Sending Location
Here an example;
>>> messenger.send_location(
lat=1.29,
long=103.85,
name="Singapore",
address="Singapore",
recipient_id="255757xxxxxx",
)
Sending Interactive buttons
Here an example;
Note: row button title may not exceed 20 characters otherwise your message will not be sent to the target phone.
>>> messenger.send_button(
recipient_id="255757xxxxxx",
button={
"header": "Header Testing",
"body": "Body Testing",
"footer": "Footer Testing",
"action": {
"button": "Button Testing",
"sections": [
{
"title": "iBank",
"rows": [
{"id": "row 1", "title": "Send Money", "description": ""},
{
"id": "row 2",
"title": "Withdraw money",
"description": "",
},
],
}
],
},
},
)
Sending Interactive reply buttons
Here an example;
Send reply button only displays three reply buttons, if it exceeds three reply buttons, it will raise an error and your message will not be sent.
>>> messenger.send_reply_button(
recipient_id="255757xxxxxx",
button={
"type": "button",
"body": {
"text": "This is a test button"
},
"action": {
"buttons": [
{
"type": "reply",
"reply": {
"id": "b1",
"title": "This is button 1"
}
},
{
"type": "reply",
"reply": {
"id": "b2",
"title": "this is button 2"
}
}
]
}
},
)
Sending a Template Messages
Here how to send a pre-approved template message, Template messages can either be;
- Text template
- Media based template
- Interactive template
You can customize the template message by passing a dictionary of components.
You can find the available components in the documentation. https://developers.facebook.com/docs/whatsapp/cloud-api/guides/send-message-templates
>>> messenger.send_template("hello_world", "255757xxxxxx", components={})
Webhook
Webhook are useful incase you're wondering how to respond to incoming message send by user, but I have created a starter webhook which you can then customize it according to your own plans.
Here an example on how you can use webhook to respond to incoming messages;
# Handle Webhook Subscriptions
data = request.get_json()
logging.info("Received webhook data: %s", data)
changed_field = messenger.changed_field(data)
if changed_field == "messages":
new_message = messenger.get_mobile(data)
if new_message:
mobile = messenger.get_mobile(data)
name = messenger.get_name(data)
message_type = messenger.get_message_type(data)
logging.info(
f"New Message; sender:{mobile} name:{name} type:{message_type}"
)
if message_type == "text":
message = messenger.get_message(data)
name = messenger.get_name(data)
logging.info("Message: %s", message)
messenger.send_message(f"Hi {name}, nice to connect with you", mobile)
elif message_type == "interactive":
message_response = messenger.get_interactive_response(data)
intractive_type = message_response.get("type")
message_id = message_response[intractive_type]["id"]
message_text = message_response[intractive_type]["title"]
logging.info(f"Interactive Message; {message_id}: {message_text}")
elif message_type == "location":
message_location = messenger.get_location(data)
message_latitude = message_location["latitude"]
message_longitude = message_location["longitude"]
logging.info("Location: %s, %s", message_latitude, message_longitude)
elif message_type == "image":
image = messenger.get_image(data)
image_id, mime_type = image["id"], image["mime_type"]
image_url = messenger.query_media_url(image_id)
image_filename = messenger.download_media(image_url, mime_type)
print(f"{mobile} sent image {image_filename}")
logging.info(f"{mobile} sent image {image_filename}")
elif message_type == "video":
video = messenger.get_video(data)
video_id, mime_type = video["id"], video["mime_type"]
video_url = messenger.query_media_url(video_id)
video_filename = messenger.download_media(video_url, mime_type)
print(f"{mobile} sent video {video_filename}")
logging.info(f"{mobile} sent video {video_filename}")
elif message_type == "audio":
audio = messenger.get_audio(data)
audio_id, mime_type = audio["id"], audio["mime_type"]
audio_url = messenger.query_media_url(audio_id)
audio_filename = messenger.download_media(audio_url, mime_type)
print(f"{mobile} sent audio {audio_filename}")
logging.info(f"{mobile} sent audio {audio_filename}")
elif message_type == "file":
file = messenger.get_file(data)
file_id, mime_type = file["id"], file["mime_type"]
file_url = messenger.query_media_url(file_id)
file_filename = messenger.download_media(file_url, mime_type)
print(f"{mobile} sent file {file_filename}")
logging.info(f"{mobile} sent file {file_filename}")
else:
print(f"{mobile} sent {message_type} ")
print(data)
else:
delivery = messenger.get_delivery(data)
if delivery:
print(f"Message : {delivery}")
else:
print("No new message")
return "ok"
