I'm trying to implement a button that shares the current page on WhatsApp, there's no issue with using the link on phone but on desktop I can't send it to WhatsApp web or open WhatsApp web if it's not opened yet.

I was searching for long on Stack Overflow and other webpages as well on documentation, which I can't find (I only face Android documentation but not web documentation for it).

I referred to https://api.whatsapp.com nut no info can be found here. No info about WhatsApp share API here: https://developers.facebook.com/ neither on resuts from search share WhatsApp or sharing WhatsApp.

My approach is this line as I said someone posting here: How to implements whatsapp share button in website

<a href="https://api.whatsapp.com/send?text=this%20was%20amazing%20https%3A%2F%2Fwww.google.es%2F" target="_blank">Share to whatsapp</a> 

I bet that this function was moved to WhatsApp for business, are it?

OK I found this browsing on latest Google's result pages:

<a href="https://web.whatsapp.com/send?text=this%20was%20amazing%20https%3A%2F%2Fwww.google.es%2F" target="_blank">share to whatsapp web</a> 

This does not answer the question at all as it's supposed to work as a single button with detect and fallback (api.whatsapp I mean), but it can be a nice approach to show and hide one of these two options if the client is on desktop or in mobile.

If someone knows a different approach it could be nice.

Another issue/bug with this approach is that on desktop, it opens always a new web.whatsapp.com tab even if you've it opened before.

I guess whatsapp business api client is only used pre-selected company which whatsapp grant. So, i want to know my guessing is right or not.

According to official guide, i need to register phone number to whatsapp. I guess here exist whatsapp menu. but i can't see menu. (Sorry, i dont know the way website display english language)

Official guide mentions this. "If you cant see WhatsApp account option, you cant use Business API yet"

So i search how can i access Business API, and i can see this in WhatsApp FAQ.

Finally, according to below link, WhatsApp has granted to 90 pre-selected companies. https://medium.com/callbell/what-changes-with-the-release-of-the-whatsapp-business-apis-46994316b763

As a result, if i want to use whatsapp business api, i need to use service which is provided official whatsapp partner company like twilio.

Someone tell me that My result is right?

gupshup.io provides a way to utilise whatsapp business by exposing a single api interface. I am exploring it. But the documentation is poor. I wonder how the entire conversation can be tied together. Is there any session that is initiated when the message exchange begins? The official site suggests to use Stack Overflow as forum and hence the question.

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?
