Setup your WhatsApp channel with WhatsApp Cloud API

UniLink supports the official WhatsApp Business API. You can connect the phone number and start managing your WhatsApp customer queries from UniLink. Follow the steps given below to enable your WhatsApp inbox with WhatsApp Cloud API.

Prerequisites

1. Configure your Facebook Developer App

First, you need to create your Facebook Developer app, with WhatsApp Product enabled. Go to the WhatsApp Cloud API Guide and navigate to section called Set up Developer Assets and Platform Access and follow the steps.

Once you finish this step, you can now configure your required phone numbers in the WhatsApp section of your Facebook developer app. If you complete the steps successfully, you should be able to obtain the Phone Number Id and Whatsapp Bussiness Account ID as shown in the below screenshot. UniLink will require these values for creating the WhatsApp Inbox.

Step 1. Create a system user in the System Users tab of Business Manager.

Step 2. Add the system user. Under the WhatsApp Accounts tab, select “Add People” and select the system user to grant access to the WhatsApp Business account.

FAQ

How to configure multiple numbers under a single Facebook app?

Facebook App allows configuring only a single Webhook endpoint. So create Inboxes in UniLink for all the numbers as required. You will need to configure the Webhook URL provided for only one of these inboxes in the Facebook app for all the other inboxes to work.

Additional Inbox settings

Your freshly configured WhatsApp inbox should now appear in your list of inboxes. To see this and to make additional settings in your WhatsApp inbox, go to Settings → Inboxes → click the gear icon on the associated WhatsApp inbox.

All the Additional Settings available are the same as those in your Twitter inbox. We recommend going through this link to understand the same.
