A cap on how many API requests can be made in a given time to keep the platform stable.
A rate limit is a restriction on how many requests an application can send to an API within a period, such as messages per second. Meta applies rate limits on the WhatsApp Cloud API to protect platform stability and ensure fair use, separate from the messaging limits that cap unique business-initiated conversations per day.
If an application exceeds a rate limit, requests are temporarily rejected and must be retried later, so well-built systems throttle and queue sends accordingly. For large broadcasts, respecting rate limits ensures messages go out reliably rather than failing in bursts.
Most businesses experience this transparently through their provider, which paces sends to stay within limits.
Rate limits mean large sends must be paced; a good provider handles this so your broadcasts deliver reliably instead of failing in bursts.
Defuser AI paces and queues sends to respect rate limits, so big broadcasts go out smoothly on your WhatsApp Business API.
