# Claim a guest chat session after sign-in

`POST /v1/chat/claim-guest-session`

## Request

- Base URL: `https://api.getmyhotels.com`
- URL: `https://api.getmyhotels.com/v1/chat/claim-guest-session`
- Auth: HTTP bearer

Runs `chat.claimGuestSession`. Transfers ownership of the guest conversation to the now-signed-in account, authorized by the one-time sessionToken minted alongside the guest session (critical decision #4). Re-claiming a session the caller already owns is an idempotent success.

## Request body

- object
  - `sessionPublicId` string, required
  - `sessionToken` string

## Response `200`

Success

- unknown

## Other responses

- `400`: Request validation failed or the router rejected the input
- `401`: Missing or invalid bearer session token
- `404`: Resource not found
- `426`: Reported X-GMH-App-Version is below the supported minimum — the app must update
- `500`: Unexpected server error (opaque; details stay in logs)
