​
GraphQL Endpoint

The Key Management Service exposes a GraphQL API endpoint: 
POST http://localhost:3000/graphql
All GraphQL requests should be sent to this endpoint using the POST method with a JSON payload containing your query or mutation.

​
Schema Overview

The API provides two main categories of operations:
  • Encryption Operations: Generate and rotate encryption keys, encrypt data, and retrieve metrics
  • Authentication Operations: Set and verify user passcodes and transaction PINs

​
Making Requests

​
Request Format

All GraphQL requests follow this structure: 
{
  "query": "mutation { ... }" or "query { ... }",
  "variables": {
    // Optional variables
  }
}

​
Example Request

Here’s an example of generating a client encryption key: 
curl -X POST http://localhost:3000/graphql \
  -H "Content-Type: application/json" \
  -d '{
    "query": "mutation GenerateKey($input: ClientIdentityInput!) { generateClientEncryptionKey(input: $input) { publicKey keyId } }",
    "variables": {
      "input": {
        "deviceId": "device-123",
        "appVersion": "1.0.0"
      }
    }
  }'

​
Response Format

Successful responses return data in this format: 
{
  "data": {
    "generateClientEncryptionKey": {
      "publicKey": "-----BEGIN PUBLIC KEY-----...",
      "keyId": "key-abc-123"
    }
  }
}

​
Error Handling

Errors are returned in the GraphQL standard format: 
{
  "errors": [
    {
      "message": "Error description",
      "locations": [{ "line": 1, "column": 10 }],
      "path": ["generateClientEncryptionKey"]
    }
  ]
}

​
Schema Introspection

The GraphQL API supports introspection. You can query the schema to discover available types, queries, and mutations: 
query {
  __schema {
    types {
      name
      kind
      description
    }
  }
}

​
Rate Limiting

The API implements rate limiting through throttler guards to protect against abuse. If you exceed rate limits, you’ll receive an appropriate error response.
