Official Meta wording: There was an error related to your payment method. See Meta’s error codes and billing help.
What Meta documents as causes
From Meta’s Cloud API error reference, common problems include:- Payment account is not attached to the WhatsApp Business Account (WABA)
- Credit line is over the limit
- Credit line (payment account) is not set or not active
- WABA is deleted or suspended
- Timezone not set on the WABA
- Currency not set on the WABA
- MessagingFor / on-behalf-of request is pending or declined
What to check in practice (Flowella)
Work through these in order. A card can look fine in Meta’s Billing Hub while WhatsApp Manager or Flowella still shows a payment / eligibility warning.1
Confirm the Default card is on the correct WABA
Open Meta payment method steps: Business Suite → Settings → Accounts → WhatsApp accounts → your WABA → Payment settings. The card that should be charged must show the Default badge on that WABA (not only on an ad account or a different WABA).
2
Match the WABA to Flowella
In Flowella Settings → Meta, confirm the connected WABA name and ID match the WABA you just edited. Sends bill against the connected WABA; editing a lookalike WABA will not fix the error.
3
Complete Meta business verification
Unverified businesses are often blocked from reliable paid messaging even when a card is on file. See Business verification. Flowella may show a verification banner separately from the send-log error.
4
Confirm currency and timezone were set before billing
Meta locks currency and timezone once a payment method is attached. If they were never set correctly, Meta support may be required — you generally cannot self-serve a fix after the fact. Prefer fixing this before attaching a card; see WhatsApp Business Account.
5
If it still fails, escalate with evidence
Capture the failed send time, the WABA ID, phone number ID, and any
fbtrace_id / message ID from the failure. Contact Flowella support. Account-level Meta holds (for example WABA not active, or business verification incomplete) sometimes need Meta Direct Support — Flowella cannot override Meta eligibility.
