# Check Relay bridge transaction status

`GET /api/v1/relay/bridge/check`

## Request

- Base URL: `https://api.enso.finance`
- URL: `https://api.enso.finance/api/v1/relay/bridge/check`
- Auth: HTTP bearer

Returns comprehensive information about a cross-chain Relay bridge transaction, including Relay message parameters, on-chain events, and transaction data from Enso.

## Query parameters

- `chainId` number, required
- `txHash` string, required

## Response `200`

Bridge transaction status and details

- RelayBridgeTransactionResponse
  - `sourceChainId` number, required: Source chain ID where the Relay message was sent from
