title: 1073: flow definition exceeds the size ceiling | API Docs
description: flow definition exceeds the size ceiling
---

flow definition exceeds the size ceiling. This is an HTTP 413: the payload is over a documented ceiling.

## Troubleshooting

- Check this endpoint’s request schema in the API reference; `param` in the response names the exact field at fault.
- Use an official SDK, which enforces required fields and types before the call is made.
- Compare the payload against the documented size ceiling for this field.
