Omnichannel for Customer Service offers a suite of capabilities that extend the power of Dynamics 365 Customer Service Enterprise to enable organizations to instantly connect and engage with their customers across digital messaging channels. An additional license is required to access Omnichannel for Customer Service. For more information, see the Dynamics 365 Customer Service pricing overview and Dynamics 365 Customer Service pricing plan pages.

The WhatsApp channel feature lets you integrate WhatsApp through Twilio with Omnichannel for Customer Service to engage with customers who prefer to use the WhatsApp channel.

The success of social media customer service, like all other customer service, depends on the quality of care provided. Communications from agents should be timely, accurate, sensitive, brief, and friendly, which ultimately improves the customer satisfaction and brand loyalty.

Prerequisites

Make sure channels are provisioned in your environment. More information: Provision Omnichannel for Customer Service

Note

To enable the Twilio channel in an existing environment, you must upgrade to the latest version of Omnichannel for Customer Service. For information, Upgrade Omnichannel for Customer Service.

For newly created Twilio accounts, you must disable a security setting that blocks the ability to send media files. More information: Extended notice and update on security changes: HTTP Authentication for Voice and Messaging Media enabled by default

WhatsApp message types and 24-hour session rule

Template messages: Are the outbound messages that agents send through Twilio using one of the preapproved templates? They're typically transactional messages, such as delivery alerts and appointment reminders, sent to users who have opted in to receive messages from your organization. For messages requiring localization, you must get the message approved by WhatsApp in each language. For more information about WhatsApp message templates, see WhatsApp documentation.
Session messages: According to WhatsApp, session messages are incoming messages from a customer or outgoing replies by an agent to the incoming messages, within 24 hours. A messaging session starts when agents receive a message from a customer. It lasts for 24 hours from the most recently received message. Session messages don't need to follow a template, and can include media attachments.
24 hours session rule: A messaging session starts when an agent receives a message from a customer or replies to the incoming message from the customer. When the customer sends a message, the agent has 24 hours to reply from the time the agent received it. However, after 24 hours, the agent can send a message to customer only by using a predefined and approved template.
