# Extend your session

`POST /platform_identity_api/auth/token/extend`

## Request

- Base URL: `https://api.stablesea.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.stablesea.com/platform_identity_api/auth/token/extend`
- Auth: none declared

Requires both access and refresh cookies. The session duration cap still applies. Check Success, not only HTTP status: a refused extension can return HTTP 200 with Success=false. An absent or invalid access cookie returns a plain-text 401. Response keys use PascalCase.

## Response `200`

OK

- IdentitySessionTokenOutput
  - `Message` string
  - `Success` boolean

## Other responses

- `401`: Unauthorized

## Changes

- **2026-10-15** `33870379032d`: 1 info
  - endpoint added
