Idempotency

​

Usage

curl -X POST https://api.mpcvault.com/v1/createWallet \
  -H "Content-Type: application/json" \
  -H "x-mtoken: YOUR_API_TOKEN" \
  -H "idempotency-key: 550e8400-e29b-41d4-a716-446655440000" \
  -d '{"vaultUuid": "...", "networkType": "NETWORK_TYPE_ETHEREUM"}'

Requirements

​

How It Works

1. Include a unique idempotency-key header with your request
2. If the request fails due to network issues, retry with the same key
3. MPCVault returns the cached response if the key was already used
4. This prevents duplicate wallet creation or transaction signing

​

When to Use

• createWallet - Prevent duplicate wallet creation
• createSigningRequest - Prevent duplicate transaction requests
• createBatchPayment - Prevent duplicate batch payments
