In this article, we will explore how the WhatsApp: Customer Service Window Check condition can be leveraged to create automated workflows and send free-form messages. This feature enables you to determine if an active Customer Service Window is open between your business and a customer. While the window is open, you can send unlimited free-form messages at no cost for up to 1,000 service conversations each month.
To send free-form messages, first confirm if the customer service window is open. If it is open, you can send messages freely. Responding to a customer’s inbound message automatically opens a service conversation. Businesses are allotted 1,000 free service conversations monthly, significantly reducing messaging costs.
Navigate to Automation> Workflows > Create Workflow > Start from Scratch.
Rename the workflow as you see fit, then add a suitable workflow trigger.
Add an action by clicking the plus icon and selecting “WhatsApp: Customer Service Window Check.” The WhatsApp Customer Service Window Check feature allows businesses to select from multiple connected WhatsApp numbers within a location when verifying the service window.
Only numbers with an “ACTIVE” status are available for selection, ensuring accurate workflow execution. This enables businesses to validate service windows for the correct phone numbers, streamline customer support, and efficiently manage multiple WhatsApp interactions.
Review the action details, then save it!
This action creates two branches: Open and Closed.
Select the WhatsApp action and choose “None – Free-form message.” This allows you to send unlimited messages during the open window, using the 1,000 free service conversations.
Choose a WhatsApp action and select a marketing or utility template to initiate a new conversation.
If the customer service window is closed, meaning the customer hasn’t replied within 24 hours, you can only send WhatsApp marketing or utility templates.
Conversations represent 24-hour message threads between your business and customers, forming the basis for WhatsApp pricing. Conversations can be initiated through free-form messages or by using pre-approved templates.
These conversations are opened when you send a pre-approved marketing, utility, or authentication template to a customer. If an existing conversation of the same category is open, no new conversation is initiated. Otherwise, a new 24-hour conversation starts.Example:
2. Service Conversations
A service conversation begins when any message other than a template is delivered, and no open conversation of any category exists.
Example:
3. Customer Service Window
A Customer Service Window is a 24-hour period initiated when a WhatsApp user messages your business. During this time, free-form messages can be sent without additional charges as long as the window remains open.
4. Free Tier Conversations
WhatsApp Business Accounts (WABA) receive 1,000 free service conversations per month across all business phone numbers. This allowance resets monthly. Service conversations are included in this free tier, but marketing, utility, and authentication conversations are not.
