FAQ

Zendesk + WhatsApp — common questions

How do WhatsApp messages appear in Zendesk?

WhatsApp messages from customers create tickets in Zendesk automatically via WA.Expert. The ticket shows the customer's name, phone number, and full message history. Agents see the conversation in their normal Zendesk interface — there is no separate tool to monitor.

Can agents reply to WhatsApp customers from Zendesk?

Yes — agents type their reply in the Zendesk ticket comment box as normal. WA.Expert intercepts the reply and delivers it to the customer as a WhatsApp message. The agent never needs to open WhatsApp — they work entirely in Zendesk.

Can I send proactive WhatsApp messages from Zendesk?

Yes — WA.Expert adds a WhatsApp send button to Zendesk ticket and contact views. Agents can send outbound WhatsApp messages (using pre-approved templates) directly from the Zendesk interface for proactive updates, check-ins, or follow-ups.

Does this work with Zendesk Suite and Zendesk Support?

Yes — WA.Expert integrates with Zendesk Support (ticketing) on all plans. Zendesk Suite's messaging features (Sunshine Conversations) offer an alternative native WhatsApp connection, but WA.Expert provides more flexibility for Indian businesses needing custom template management and broadcast capabilities alongside support.

How are WhatsApp message threads matched to Zendesk tickets?

WA.Expert matches incoming WhatsApp messages to existing Zendesk tickets using the customer's phone number. If an open ticket exists from the same number within the past 24 hours, the new message is added as a comment. If no open ticket exists, a new ticket is created. This threshold is configurable.

Can I use WhatsApp for Zendesk ticket notifications to agents?

Yes — Zendesk triggers can send WhatsApp notifications to agent phone numbers via WA.Expert. Common use cases: new high-priority ticket assigned → WhatsApp alert to assigned agent, SLA breach approaching → WhatsApp to team lead, escalated ticket → WhatsApp to manager.
