# Get a MED dispute

GET https://client.api.corpx.com/v1/accounts/{accountId}/pix/med/{id}

Everything from the list plus the timeline visible to the account holder (`events`), the messages exchanged with the review (`messages`), the attachments with signed `downloadUrl` (`evidences`), the steps CorpX already executed in the return (`steps`) and the `can*` flags saying what is enabled right now. In `info_requested`, `infoRequest` carries the review's question and its deadline.

Reference: https://docs.api.corpx.com/ib/referencia/pix-med/get-pix-med

## Authentication

- `Authorization` header (bearer token, required) — Bearer authentication of the form `Bearer <token>`, where token is your auth token.

## Request

### Path parameters

- `accountId` (string, required) — Account identifier.
- `id` (string, required) — The `medId`.

### Headers

- `X-Tenant-Id` (string, required) — Tenant context used for authorization and routing.
- `X-Request-Timestamp` (string, required) — Unix seconds. Required on the signed host; tolerance is 300s either way (`403 request_timestamp_skew`).
- `X-Content-SHA256` (string, required) — Lowercase hex SHA-256 of the body. An empty body hashes the empty string, so the header is always present. Mismatch returns `400 body_hash_mismatch`.
