WhatsApp error 131042: business account payment issue

Who is actually billing whom?

Two companies, and only one of the bills has anything to do with your provider.

Meta charges for delivered messages on the WhatsApp Business Platform, and it charges the payment method attached to your own WhatsApp Business Account. That relationship is between you and Meta. A provider sits beside it, charging for access and tooling, and never sees those message charges at all.

This is why the error cannot be fixed by contacting your provider, and why nobody in that position can add a card on your behalf. It also means the message cost cannot be marked up by a provider that never receives it.

Where is the payment method set?

In WhatsApp Manager, on the WhatsApp Business Account that owns the number.

You add or update a payment method there, and the account has to have one before certain sends will work at all. Marketing template sends in particular require it, which is why the error often appears the first time someone tries a promotional send on an account that has only ever replied to customers.

The API deliberately cannot do this. There is no endpoint for attaching a card, by design, because it is an account level commercial relationship rather than a messaging operation.

Common mistakes

• Asking a provider to fix it. The billing relationship is between you and Meta, and no API can attach a card.
• Assuming a provider fee covers message costs. They are separate bills from separate companies.
• Trying marketing templates on an account with no payment method. Meta requires one for those sends.
