Following to this documentation https://developers.facebook.com/docs/whatsapp/business-management-api/phone-numbers about whatsapp business accounts, it is possible to have multiple phone numbers in one account. Does someone know how you can define from which number a message is send, when sending a message to a client? There is nothing in the api about sending messages.

following to the documentation you can read the phone numbers and their whatsapp id via

curl -X GET \ 'https://graph.facebook.com/v3.3/your-whatsapp-business-account-id/phone_numbers' \   -d 'access_token=your-access-token' 

example result

{   "data": [     {       "verified_name": "Jasper's Market",       "display_phone_number": "+1 631-555-5555",       "id": "1906385232743451",       "quality_rating": "GREEN"     },     {       "verified_name": "Jasper's Ice Cream",       "display_phone_number": "+1 631-555-5556",       "id": "1913623884432103",       "quality_rating": "NA"     }   ], } 

I would expect something like a senderId field when sending a message.

While trying Developer setup: Single Instance from WhatsApp Business Api with following documentation at https://developers.facebook.com/docs/whatsapp/installation/dev-single-instance#setup

Getting the following error while trying Initial Setup#Step 7

Their was an error in connecting https://localhost:9090/v1/health 

Using postman collection as suggested in Step 6. Seems to be docker issue, but not sure.

Any idea?

I'm trying to send a document media message in Whatsapp Business API using LINK instead of uploading the file, but I got the following error:

"errors":[         {            "code":1008,          "title":"Required parameter is missing",          "details":"Parameter 'id' is mandatory for type 'document'"       }    ] 

Here is the JSON request object:

{      "recipient_type":"individual",    "to":"TELEPHONE_NUMBER_HIDDEN",    "type":"document",    "document":{         "link":"google-drive/https://drive.google.com/open?id=HIDDEN_DOCUMENT_ID",       "provider":{            "name":"google-drive"       },       "caption":"CAPTION MESSAGE"    } } 

Do you have any idea regarding this? I can't use external services like Twilio.

I am new to .net-core and docker. The problem I am going to explain here is a bit tricky, but if you have any type of questions please do ask me and I will explain it more clearly.

So, I have a docker container running on my localhost for whatsapp business api, as explained in Whatsapp Business Api Documentation.

I have already downloaded Postman Collection of Whatsapp Business Api from Whatsapp Business Postman Collection.

Everything seems to be working perfectly fine. But now I want to call these pre-built apis with .net-core and get the responses. As I couldn't find anything good, or also as a newbie it's difficult for me to understand. So for some knowledge I would like to know How can I call them and get the effective response. For example, take an example of a post request for admin login

API: {{URL}}/v1/users/login Authorization -> (Basic Auth) username: admin password: **** 

RESPONSE: {     "users": [         {             "token": "eyJhbGciOiAiSFMyNTYiLCAidHlwIjogIkpXVCJ9.eyJ1c2VyIjoiYWRtaW4iLCJpYXQiOjE1NTk5MTE1NTUsImV4cCI6MTU2MDUxNjM1NSwid2E6cmFuZCI6LTQxMzgyNDE0MjYwMDI5NjA1OTl9.PYAhEilXX3GDhRo0O-M0V0aXWfL5THJkG65LfIesxh4",             "expires_after": "2019-06-14 12:45:55+00:00"         }     ],     "meta": {         "version": "v2.23.4",         "api_status": "stable"     } } 

the images for more explanation can be seen below in the request and response links.

The Login Authentication UI Image.

The Login Authentication Postman Image.

The Login Authentication Response New Password UI Image.

The Login Authentication Response Postman Image.

Now with this token I can create more users by other api calls. How can I call an api like this and get the response with token and use that token for more functionalities or api calls with .netcore.

Thank you.

As far as I know, to use the WhatsApp Business API one must use the APIs developed by WhatsApp regional partners

Looking at our a regional partner API, one cannot send an image to the customer as for the first message of the conversation

Is this a WhatsApp Business API restriction or is can be the partner API restriction?
