title: 4006: Spend limit exceeded. | API Docs
description: The send would exceed a daily or monthly spend cap.
---

**HTTP status:** `422` or `429`, depending on the request.

The projected charge would cross the account’s or number’s spend ceiling. With a known reset instant the response is 429 with Retry-After and error.retry\_after naming the exact reset; without one it is 422 with neither. Nothing was journaled.

## Troubleshooting

- When error.retry\_after is present, wait that many seconds; the reset is the UTC day or month boundary.
- A daily cap refuses any message carrying a template part; a message without one, such as a reply inside an open customer window, is still accepted past a daily cap and its charge still counts. The monthly cap refuses every send.
