A WhatsApp delivery problem may be related to the notification history, the connected number, or the available messaging credits. Check those areas before sending the same message repeatedly.

The verified page provides Whatsapp notification history, Link your number, Set up auto top-up, and Top up whatsapp credits. It does not expose a failure reason in the main settings view.

Steps

Open Marketing Tools from the Rekaz navigation.
The Marketing Tools page opens.
Under WhatsApp messaging, select View details.
The WhatsApp notification settings open.
Select Whatsapp notification history and locate the message by its time and recipient. Do not resend it repeatedly while its status is unclear.
The available WhatsApp message history opens for review.
Return to the WhatsApp settings and select Link your number to verify or restore the official number connection when required.
The number-connection workflow opens.
Select Top up whatsapp credits if the account does not have enough credits for another message.
The WhatsApp credit top-up flow opens.
Select Set up auto top-up when you want Rekaz to replenish credits according to the account's configured billing rule.
The auto top-up setup opens.
If the message still fails after confirming history, connection, and credits, select Contact support and provide the message time, recipient number with most digits masked, and the visible status. Never provide passwords or API secrets.
Support receives enough non-sensitive context to investigate the delivery problem.
