Is it possible to SendMessage to multiple contacts? about whatsapp-api

[avoylenko]

This possibility is missing, but we could implement it in the future service version.

Is it possible to send a message to multiple numbers with just one api call? Or is there any other way to, if sending the same file multiple times, not have to download the whole file every time?

In the case of sending files, you can send the message and the file to yourself and then forward it to any other person or group. It will not appear to them that it is a forworded message because it is actually your message.

That's a good call. However, when I try to use message/forward, it gives me

{
  "success": false,
  "error": "Message not Found"
}

despite me giving it a correct message ID. The body is supposed to look like this, right?

{ "chatId": "[email protected]", "messageId": "messageId fetched from saved messages" }

Hello,
I'm having the same issue.
For documentation purposes, here is my attempt.

I have executed the following command to fetch the last message that a number sent to the container:

$Uri = 'http://10.xx.xx.xx:3000/chat/fetchMessages/xxxxx'
$Form = @{
    chatId='[email protected]'
}
$Result = Invoke-RestMethod -Uri $Uri -Method 'Post' -Body $Form
$Result.messages[-1].id

Where I get the result:

fromMe      : False
remote      : [email protected]
id          : xxxxxxxx2F3AFC186D283918xxxxxxxx
_serialized : [email protected]_xxxxxxxx2F3AFC186D283918xxxxxxxx

Then I proceeded to make another request to forward that message to another user with:

$Uri = 'http://10.xx.xx.xx:3000/message/forward/xxxxx'
$Form = @{
    chatId='[email protected]'
    messageId='xxxxxxxx2F3AFC186D283918xxxxxxxx'
}
$Result = Invoke-RestMethod -Uri $Uri -Method 'Post' -Body $Form

Where I get the result:

Invoke-RestMethod : {"success":false,"error":"Message not Found"}
At line:6 char:11
+ $Result = Invoke-RestMethod -Uri $Uri -Method 'Post' -Body $Form
+           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidOperation: (System.Net.HttpWebRequest:HttpWebRequest) [Invoke-RestMethod], WebException
    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

I think I'm using the API correctly yet something feels off.
I have tested the last request with the id and the _serialized results in the messageId parameter and keep getting the same error.
Can anyone guide me to a solution? Any help is much apreciated.
Please don't judge me about Powershell 😅
