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.
