# Increased metadata size limit on End Users API

The maximum size of `profile.metadata` on the End Users API has been increased from 4 KB to 10 KB.

This applies to both:

* `POST /v2/end-users/`
* `PATCH /v2/end-users/{end_user_id}`

The cap is now enforced consistently on both endpoints. Requests with metadata over 10 KB return `400` with `"Metadata exceeds the maximum size of 10 KB."` No changes are required on your end; existing integrations sending smaller payloads are unaffected.

For full details, see the [End Users API reference](/reference/end-users/overview).
