Setup your WhatsApp channel with WhatsApp Cloud API

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

Prerequisites

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.

If you've not done this before, you might have this screen below, select "Set up".

Once you finish the above steps, 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. OMNI will require these values for creating the WhatsApp Inbox.

Configure a system user for your Facebook Business Manager

Create a system user in your Business Manager with access to the WhatsApp App. Generate an access token for the user, which will be required as the API key for setting up an inbox in OMNI.

When generating the access token, make sure the whatsapp_business_management, and whatsapp_business_messaging permissions are selected.

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.

Step 3. Generate the access token and request permissions.

Note this phone number is not your actual number but the webhook number that we will provide you. It is to be kept a secret to avoid abuses.
• The value for the verify token should be the Webhook Verify Token which you received during inbox creation.

You should also subscribe to message fields events under Webhooks Fields on your Facebook Developer app.

Once you finish all the steps, the section should look like the following screenshot.

Please contact ORENCloud for the Webhook URL, you must use the webhook URL provided by us only.

FAQ

How to configure multiple numbers under a single Facebook app?

Facebook App allows configuring only a single Webhook endpoint. So create Inboxes in OMNI 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.
