How to Integrate Microsoft Dynamics 365 Business Central with WhatsApp Using Twilio

This guide explains how to achieve this integration using Twilio's WhatsApp API.

Step 1: Register and Set Up Twilio

1. Visit Twilio and create an account.
2. Access your Twilio Console and locate your Account SID and Auth Token under the "Project Info" section.
3. In the Twilio Console, navigate to the "Messaging" section and set up a WhatsApp-enabled phone number.

Step 2: Create Business Central Table for Settings

Define a table to store your Twilio credentials and WhatsApp settings.

table 50100 "WhatsApp Setup"
{
    DataClassification = ToBeClassified;
    fields
    {
        field(1; "Account SID"; Text[50]) { }
        field(2; "Auth Token"; Text[50]) { }
        field(3; "From Number"; Text[20]) { }
        field(4; "To Number"; Text[20]) { }
        field(5; "Message Body"; Text[250]) { }
    }
    keys
    {
        key(PK; "Account SID") { Clustered = true; }
    }
}
        

Step 3: Create Integration Page

Design a page for configuring WhatsApp settings and sending test messages.

page 50100 "WhatsApp Integration Setup"
{
    PageType = Card;
    ApplicationArea = All;
    SourceTable = "WhatsApp Setup";

    layout
    {
        area(content)
        {
            group("API Credentials")
            {
                field("Account SID"; "Account SID") { ApplicationArea = All; }
                field("Auth Token"; "Auth Token") { ApplicationArea = All; }
            }
            group("WhatsApp Numbers")
            {
                field("From Number"; "From Number") { ApplicationArea = All; }
                field("To Number"; "To Number") { ApplicationArea = All; }
            }
            group("Message Settings")
            {
                field("Message Body"; "Message Body") { ApplicationArea = All; }
            }
        }
    }

    actions
    {
        area(processing)
        {
            action("Save Credentials")
            {
                ApplicationArea = All;
                trigger OnAction()
                begin
                    // Logic to save credentials
                    Message('Credentials saved successfully.');
                end;
            }
            action("Send Test Message")
            {
                ApplicationArea = All;
                trigger OnAction()
                var
                    HttpClient: HttpClient;
                    HttpRequestMessage: HttpRequestMessage;
                    HttpResponseMessage: HttpResponseMessage;
                    Content: HttpContent;
                    JsonObject: JsonObject;
                begin
                    "WhatsApp Setup".Get();

                    // Prepare request
                    HttpRequestMessage.SetRequestUri('https://api.twilio.com/2010-04-01/Accounts/' + "Account SID" + '/Messages.json');
                    HttpRequestMessage.Method := 'POST';
                    HttpRequestMessage.GetHeaders().Add('Authorization', 'Basic ' + Convert.ToBase64String("Account SID" + ':' + "Auth Token"));
                    JsonObject.Add('From', 'whatsapp:' + "From Number");
                    JsonObject.Add('To', 'whatsapp:' + "To Number");
                    JsonObject.Add('Body', "Message Body");
                    Content.WriteFrom(JsonObject.ToString());
                    Content.GetHeaders().Add('Content-Type', 'application/json');
                    HttpRequestMessage.Content := Content;

                    // Send request
                    if HttpClient.Send(HttpRequestMessage, HttpResponseMessage) then begin
                        HttpResponseMessage.Content().ReadAs(JsonObject);
                        if HttpResponseMessage.IsSuccessStatusCode() then
                            Message('Message sent successfully.')
                        else
                            Message('Error: ' + JsonObject.GetValue('message').AsText());
                    end else
                        Message('Failed to send request.');
                end;
            }
        }
    }
}
