Does somebody know how I can send or attach a .pdf document to Whatsapp in C# or vb.net?

I tried to look in their api, but I didnt find anything.

Thanks for any help

I am currently writing a chatbot for WhatsApp. I use the 360dialog platform, which makes it possible to work with the WhatsApp Business API.

When the client sends a message, I see the following JSON object in the logs of my application:

{     "messages": [         {             "from": "77773336633",             "id": "ABGGd3c1cGY_Ago61ytHsZknvtLv",             "image": {                 "id": "ffd23134-2dae-4fed-b5f8-0ce7867b6ddd",                 "mime_type": "image/jpeg",                 "sha256": "bd02100d961b5a1dbaae1dd645485ebbfeda77b44e82c015f1cf29b05654ccb9"             },             "timestamp": "1605703542",             "type": "image"         }     ],     "contacts": [         {             "profile": {                 "name": "Nurzhan Nogerbek"             },             "wa_id": "77773336633"         }     ] } 

I can't find any information in the documentation about how to download this file. In my case, I want to upload this image file that the client sends to my file storage. Please tell me which URL method from the WhatsApp API is responsible for this mechanism?

P.S. At the same time, I can send files to clients. This information is available on the official documentation.

We are building a e-retail bot on WhatsApp platform. I would like to understand if there is a possibility to integrate the Whatsapp Business Api with the product catalog option they provide in the WhatsApp for Business App.


WhatsApp Business API - https://www.whatsapp.com/business/api/?lang=en

WhatsApp for Business - https://www.whatsapp.com/business


The flow that I am looking for is

1. We will list all the products available on the WhatsApp for Business App
2. Build a conversation bot which uses WhatsApp Business API
3. Using API from WhatsApp Business API, open a product catalog or send a message with a call to button which will open product description or cart.

Is this something that is possible?

Edit: I see that I can only use and send to numbers associated with Twilio. My question was to see if I didn't have to use numbers associated with Twilio, for example, if I were to make a website that can send numbers on WhatsApp, like my own WhatsApp web, how do I do that, as in how do I make a website that can send messages through WhatsApp just like WhatsApp web?

I want to make a python program, that asks for your number when you start it. It then asks for the number you want to send the message to. This code will ultimately be running on android if that helps.

from twilio.rest import Client  contact = '' contact = input('Which number do you want to send the message to: ') message = '' message = input('What do you Want to send: ') account_sid = '_'  auth_token = '_'  client = Client(account_sid, auth_token)  #some code to get my number #some code to get my number my_number = #i got my number   message = client.messages.create(                                from_='whatsapp:'+ my_number,                                 body=message,                                     to='whatsapp:' + contact ,                           )    print(message.sid) 

So it's the code to get the user's number that I need help with. Another option I've been considering is manually inputting the number and using that (I will add an OTP if I go this route but not rn). Which sounds like the better option?

I'm new to Twilio's APIs so any help would be appreciated.

I had cloned these file as per facebook instructions

And then Step 1: Create a biz Directory for the Setup Scripts

mkdir ~/biz; cd ~/biz; 

Step 2: Get the WhatsApp Business API Client Configuration Files

   db.env docker-compose.yml multiconnect-compose.yml 

Step 3: Set the WA_API_VERSION Environment Variable

export WA_API_VERSION=2.31.5 

Step 4: Start the WhatsApp Business API Client

docker-compose up -d 

The resulting output should look like the following:

Recreating whatsbusinessapi_db_1 ... done Creating whatsbusinessapi_wacore_1 ... done Creating whatsbusinessapi_waweb_1  ... done 

Step 5: Verify Containers Are Running

docker-compose ps 

output :

          Name                         Command               State                     Ports                    --------------------------------------------------------------------------------------------------------------- whatsbusinessapi_db_1       docker-entrypoint.sh -p 54 ...   Up      5000/tcp, 5432/tcp, 0.0.0.0:5000->6000/tcp whatsbusinessapi_wacore_1   /opt/whatsapp/bin/wait_on_ ...   Up      6250/tcp, 6251/tcp, 6252/tcp, 6253/tcp     whatsbusinessapi_waweb_1    /opt/whatsapp/bin/wait_on_ ...   Up      0.0.0.0:9090->443/tcp 

By default, the Webapp container will be running on port 9090 (https://localhost:9090) as per facebook but when i tried https://localhost:9090

So anyone have idea please.
