Chat App Message Service:FAQ about WhatsApp channels

Chat App automatically checks your network connectivity to Meta. If the register button is gray, your network connection to Meta is unavailable. Visit the official Meta website to verify that you can access it.

The Embedded Signup flow does not include Meta business verification. You must complete this step on the official Facebook website.

WhatsApp allows you to modify an approved message template up to 10 times in 30 consecutive days (or once every 24 hours). There is no limit on how many times you can modify a rejected or paused template.

If you no longer need a WhatsApp message template, delete it in the Chat App Message Service console.

1. Open contacts on your phone.

2. When you add an international phone number, enter the plus sign (+) first.

3. Enter the country/region code. Then, enter the complete phone number.

   Note

   A country/region code is a numeric prefix required before an international phone number to route the call to the correct country/region.

   For example, if the contact is in the United States (country code: 1, area code: 408), enter +1 408 XXX XXXX.

Note:

• Remove the leading zero or any special calling codes from the phone number.

• For phone numbers in Argentina (country code: 54), add a "9" between the country code and the area code, and remove the phone number prefix "15". What you enter must be a 13-digit phone number in the following format: +54 9 XXX XXX XXXX

• For phone numbers (including Nextel numbers) in Mexico (country code: 52), add a "1" after "+52".

The following rules and restrictions apply when you send messages from a WhatsApp business number:

1. Send messages only to users who have opted in to receive them. This helps avoid reports or complaints.

2. Ensure that your message content complies with the WhatsApp Business Terms of Service.

3. Businesses must use a WhatsApp-approved message template to initiate a conversation. Outside the customer service window, only approved templates can be sent. A 24-hour customer service window opens when a user initiates contact or replies to a template message. During this window, businesses can reply with interactive or free-form messages, or send approved templates.

4. The number of marketing messages a user can receive over a given period is dynamic. It depends on the user's recent interactions with marketing messages and whether they have opted out of promotions in the WhatsApp app.

5. Starting April 1, 2025, Meta will suspend sending marketing messages to WhatsApp users with U.S. phone numbers.
