How to Add Payment Method for WhatsApp API Billing

• This step happens on Meta's side, once per Business Portfolio — not inside ChatSyncs.
• Meta bills you directly for WhatsApp messages (per delivered message), not ChatSyncs. See What WhatsApp API Pricing Really Means for the plain-English breakdown, or Message Categories & Pricing for the full API-level rules.
• Meta requires a payment method on file before it lets a paid template message go out. Since October 1, 2026 free-form replies inside the customer service window need one too once the number has used its 1,000 free service messages for the month — without a payment method, Meta stops delivering them.

Set it up#

1. 1

   Open your Business Portfolio's settings

   In Meta Business Suite, click your business portfolio name in the top-left switcher, then click the gear icon next to it to open Settings.

   

2. 2

   Open your WhatsApp account's payment settings

   Under Accounts → WhatsApp accounts, select the WhatsApp Business account you want to bill. Its current Payment method (if any) shows on the right. Click Payment settings.

   

3. 3

   Add a payment method

   This opens Billing & payments. Under Payment methods, click Add payment method. You can have more than one card on file — Meta uses whichever is marked Default.

   

4. 4

   Set your location and currency

   In the Add payment information dialog, choose the Country/region, Currency, and timezone, then click Next.

   

5. 5

   Enter your card details

   On the Debit or credit card screen, fill in the Name on card, Card number, expiry (MM/YY), and CVV, check the authorization box, then click Save.

   

Expected result: The account's Payment methods list shows your new card, and it's ready to be billed for template messages, based on the template's category and the recipient's country.

What's next#

With a payment method on file, your number can keep sending paid template messages without interruption. See Message Categories & Pricing for what actually gets billed, or head back to How to Connect Your Number to ChatSyncs if you haven't finished that yet.
