Step 1: Prepare the Requirements
Before you start, make sure you have everything required for a successful WhatsApp Cloud API setup.
- Meta Developer Account for creating the app
- Facebook Business Manager access for managing your business assets
- A valid phone number that is not currently active on a personal WhatsApp account
- Your live WordPress website
- Valid business details and documents for Meta business verification, when required
- A valid payment method such as a credit card or another supported billing method as per Meta policies
Important: WhatsApp Cloud API may require business verification and billing setup for full access, production messaging, and higher messaging limits.
Step 2: Create a WhatsApp Cloud API App in Meta
Go to the Meta Developer Dashboard and create a new app for your business. Add the WhatsApp product to the app, then begin the API setup process.
This is the step where your business identity, WhatsApp number, and API access are connected under Meta’s official infrastructure.
- Create a new Meta app
- Select the appropriate business-oriented app flow
- Add the WhatsApp product
- Start the API setup process
- Add and verify your WhatsApp Business phone number

Step 3: Collect the Required API Credentials
After your app and phone number are configured, Meta provides the values needed to connect WordPress to the WhatsApp Cloud API.
- App ID
- App Secret
- Access Token
- Phone Number ID
- WhatsApp Business Account ID
These credentials are entered into your WordPress plugin settings so your website can communicate directly with the WhatsApp Cloud API.

For production use, a permanent access token is generally recommended instead of relying only on temporary test tokens.
Step 4: Connect WordPress to WhatsApp Cloud API
Install and activate NXT Cloud Chat in WordPress, then open the plugin settings and paste the required API details. You can also explore the plugin overview on the NXT Cloud Chat homepage.
- App ID
- App Secret
- Access Token
- Phone Number ID
- WhatsApp Business Account ID
After saving the settings, WordPress is connected to the WhatsApp Cloud API. At this stage, your website can validate the connection and prepare for real-time message handling.

Step 5: Configure Webhooks for Incoming Messages
Webhooks allow your WordPress website to receive incoming WhatsApp events in real time. Without webhook configuration, you may be able to connect the API, but incoming messages will not appear properly inside the dashboard.
- Copy the callback URL from the plugin
- Copy the verify token from the plugin
- Paste both values into Meta webhook settings
- Verify the webhook
- Subscribe to the messages field
Once webhook verification succeeds, incoming messages can sync into the WordPress chat interface.
Step 6: Test the Connection
After the API connection and webhook setup are complete, test the system by sending a message from your phone to the registered WhatsApp Business number.
- Open WhatsApp on your phone
- Send a message to your business number
- Open the WordPress chat window
- Check whether the incoming message appears
- Reply from WordPress to confirm the connection works correctly

Understanding the 24-Hour Messaging Rule
WhatsApp allows free-form replies within a 24-hour customer service window after the user sends a message first. Outside that window, only approved template messages can be sent.
This is an official WhatsApp policy and applies regardless of which plugin or system you use.
- Inside 24 hours: free-form replies are allowed
- Outside 24 hours: use approved templates
What You Can Do After Setup
Once WordPress is connected to the WhatsApp Cloud API, you can use the integration for multiple practical workflows.
- Send and receive WhatsApp messages
- Manage contacts and groups inside WordPress
- Send approved template messages
- Support WooCommerce customer communication
- Enable secure WhatsApp OTP login
- Run broadcast campaigns with approved templates

Yes. WhatsApp Cloud API uses Meta’s official conversation-based pricing model. For production messaging, you generally need a valid payment method such as a credit card or another supported billing method according to Meta’s policies.
