WhatsApp error 131057: Account in maintenance mode

Code 131057 means the WhatsApp Business Account is temporarily in maintenance mode and cannot process sends. Meta's documented example is a throughput upgrade: when a business phone number qualifies for higher throughput, the platform upgrades it, and during that upgrade the number is briefly unusable. The throughput documentation says the process can take up to a minute, after which the number returns to service at the new level and receives further upgrades without downtime.

Because the window is short, 131057 is usually a blip rather than an outage. A handful of messages fail, then everything succeeds again. If you see it persist for more than a few minutes, it is worth checking account status, but the normal response is simply to retry after a pause.

There is nothing to change in your request, token, or template, and the messages were not sent.

It surfaces synchronously, and because upgrades are triggered by crossing the documented throughput criteria, it tends to arrive at the least convenient moment - mid-campaign, when volume is highest. Treat it like 131016 in your retry policy, but with a shorter, fixed delay.

Treat 131057 as retryable with a short delay in your error policy, and back sends with a durable queue so a one-minute maintenance window causes a delay rather than lost messages. Subscribe to business_capability_update so your system can log and correlate upgrades with the brief error burst.
