2. Add a New Channel

2.1 Navigate to Settings > Channel.

2.2 Click on the “+” button to create a new channel.

2.3 Assign a unique name to your channel and select the appropriate time zone for your business.

2.5 Enter Your WhatsApp API Number in the provided field.

2.6 Click the Save button to confirm your settings.

2.7 Once you have completed the above steps, contact our onboarding team to assist you in obtaining the verification code required to verify your number.

Make sure to use a new phone number that has not been previously associated with other WhatsApp services. This number should be exclusively dedicated to the WhatsApp Business Platform (API).

3. Integrate WhatsApp API with Facebook

After saving your channel settings, a blue button labelled “Continue with Facebook” will appear.

3.1 Click "Continue with Facebook"

3.2 You will be redirected to the Meta page. Click “Continue as” and then “Get Started”.

3.3 Fill in your Business Information, create your WhatsApp Business Account, complete your WhatsApp Business Portfolio.

3.4 Verify your WhatsApp Business number.

  • Choose either text message or phone call for verification.

  • If you choose text message, you will receive a verification code via SMS. If you choose a phone call, you will receive a call with the code.

Ensure the phone number you register for the WhatsApp Business API can receive both SMS and phone calls.

3.5 Enter the verification code and click Next.

3.6 On the next page, click Continue and then Finish to complete the setup.


4. Finalize Setup in iSlash Platform

Return to the iSlash platform and click Save again.

To ensure everything is working correctly, test the integration by using another phone number to send a message and verify the reply.


Additional Note: Migrate a phone number to the WhatsApp Business Platform

If you're using a phone number that is already registered with WhatsApp Personal or WhatsApp Business, we kindly recommend backing up your chat history on your mobile device/iCloud/Google Drive.

If you delete your existing WhatsApp account without back up, all chat history will be lost from the mobile app.

Please note that to verify the WhatsApp API, you must use a number that is NOT currently registered with a personal or WhatsApp Business account.
