## Types

### TravelRuleExchangePrepare0

- `expectedRevision` (integer, required)
- `travelAddress` (string, required) — The recipient institution-provided TRP Travel Address. Its origin must match the approved connection.
- `connectionId` (string, optional) — Optional. Myaza resolves an unambiguous existing route from the Travel Address. Supply this when more than one scoped route matches; unknown destinations stay held.

### TravelRuleExchangePrepare1

- `expectedRevision` (integer, required)
- `providerId` (string, required) — Reviewed Myaza directory institution. The server selects a unique approved CodeVASP route; a directory ID alone does not enable it.
- `connectionId` (string, optional) — Optional explicit approved CodeVASP route. No TRP Travel Address is used.

### TravelRuleExchangeResponseMessage

- `id` (string, required)
- `status` (string, required)
- `replayed` (boolean, optional)

### ErrorEnvelopeError

- `type` (enum, required)
  - Allowed values: `AUTHENTICATION_ERROR`, `PERMISSION_ERROR`, `VALIDATION_ERROR`, `NOT_FOUND`, `CONFLICT`, `IDEMPOTENCY_CONFLICT`, `INSUFFICIENT_CREDIT`, `RATE_LIMITED`, `SERVICE_UNAVAILABLE`, `INTERNAL_ERROR`
- `code` (string, required)
- `message` (string, required)
- `request_id` (string, required, nullable)
- `details` (any, optional)
