5N ID Integration

Description

Create and authenticate a connection to the 5N ID service. The SDK automatically handles OAuth2 token management, including token acquisition, caching, and refresh.

Parameters

• clientId – your Client ID (required)
• clientSecret – your Client Secret (required)
• network – network environment: "devnet" or "mainnet" (optional, defaults to "mainnet")

Network Configuration

The SDK supports two networks: mainnet (production, default) and devnet (development). URLs are automatically resolved based on the network.

Example

import { idSdk } from '@fivenorth/id-sdk';

// Connect to mainnet (default)
const connection = await idSdk.connect({
  clientId: 'your-client-id',
  clientSecret: 'your-client-secret',
});

import { idSdk } from '@fivenorth/id-sdk';

// Connect to devnet
const devConnection = await idSdk.connect({
  clientId: 'your-client-id',
  clientSecret: 'your-client-secret',
  network: 'devnet',
});

Description

Request credentials from a user by creating a credentials access request (proposal). This sends a request to the user to share their credentials.

Parameters

• partyId – the party ID of the user whose credentials you are requesting (required)
• providers – array of credential providers: ["GOOGLE", "LINKEDIN", "GITHUB", "DISCORD", "TWITTER"] (required)

Example

await connection.createCredentialsRequest({
  partyId: 'party::123',
  providers: ['GOOGLE', 'LINKEDIN', 'GITHUB'],
});

Response

Returns void on success. Indicates that a proposal was successfully created for the user.

Description

Retrieve all approved credentials that your institution has access to, with pagination support. Returns credentials with freshness status and metadata.

Parameters (optional)

• offset – number of records to skip (default: 0)
• limit – maximum number of records to return (default: 10)

Example

// Get first page (default: offset=0, limit=10)
const allCredentials = await connection.getCredentials();

console.log(allCredentials.items); // Array of credentials
console.log(allCredentials.pagination); // { offset, limit, total }

// With pagination
const page2 = await connection.getCredentials({
  offset: 10,
  limit: 20,
});

Response

Returns a CredentialsListResponse object containing an array of credentials and pagination information.

Description

Generate a short-lived verification link for a specific credential. The link can be shared with third parties to verify the credential status.

Parameters

• contractId – the contract ID of the specific credential (required)

Example

const verification = await connection.generateVerificationLink({
  contractId: '008cb3c4e71260967ef...',
});

console.log(verification.verificationUrl); // URL to share
console.log(verification.token); // Token for status checking

Response

Returns a GenerateVerificationLinkResponse object containing verificationUrl and token.

Description

Generate verification links for multiple credentials in a single request. Useful for bulk verification operations. Maximum 100 requests per batch. Each item is processed independently - partial failures are returned in the response.

Parameters

• requests – array of verification link requests (required, max 100 items)
• Each request object contains:
• - contractId – the contract ID (required)

Example

const batchResult = await connection.generateVerificationLinksBatch({
  requests: [
    { contractId: '00020bf30f6b3714bff...' },
    { contractId: '008cb3c4e71260967ef...' },
  ],
});

batchResult.results.forEach(result => {
  if (result.result) {
    console.log(`Success: ${result.result.verificationUrl}`);
  } else if (result.error) {
    console.error(`Error: ${result.error.message}`);
  }
});

Response

Returns a BatchGenerateVerificationLinkResponse object containing an array of results. Each result contains either a verification link response or an error for failed requests.

Description

Check the verification status for a verification token. This is a public endpoint (no authentication required) and is typically used by third parties who received a verification link.

Parameters

• token – the verification token from the verification URL (required)

Example

const status = await connection.checkVerificationStatus('verification-token');

console.log(status.status); // 'strong', 'moderate', 'weak', etc.
console.log(status.color); // 'green', 'amber', 'red'
console.log(status.isActive); // boolean
console.log(status.credentialData); // Original credential metadata

Description

Resolve credentials using a single method. The behavior depends on the options provided: use `q` (email/username) for forward lookup or `partyId` for reverse lookup. Forward lookup finds credentials when you have a user's email or username. Reverse lookup finds all credentials associated with a specific party ID. This is a unified method that automatically determines whether to perform forward or reverse lookup based on the provided options.

Parameters

• options – ResolveCredentialsOptions object containing either:
• - q – email address or username for forward lookup (case-insensitive)
• - partyId – party ID for reverse lookup (e.g., "party::12200d35764b9b490251e499af00626b54516c4f3f1c021c2eb72bf7c72f38662cb0")
• Note: Provide exactly one of q or partyId, but not both.

Example

import idSdk from '@fivenorth/id-sdk';

const connection = await idSdk.connect({
  clientId: 'YOUR_CLIENT_ID',
  clientSecret: 'YOUR_CLIENT_SECRET',
  network: 'mainnet' // or 'devnet'
});

// Forward lookup: Find credentials by email or username
const result1 = await connection.resolveCredentials({
  q: 'user@example.com'
});

console.log('Found credentials:', result1.credentials);
console.log('Party ID:', result1.credentials[0]?.partyId);

// Reverse lookup: Find all credentials by party ID
const result2 = await connection.resolveCredentials({
  partyId: 'party::12200d35764b9b490251e499af00626b54516c4f3f1c021c2eb72bf7c72f38662cb0'
});

console.log('All credentials for this party:', result2.credentials);

Response

Returns a ResolveCredentialsResponse object containing an array of credentials. Each credential includes partyId, userId, email, username, kycProvider, contractId, and metadata.

Response Example

{
  "credentials": [
    {
      "partyId": "party::12200d35764b9b490251e499af00626b54516c4f3f1c021c2eb72bf7c72f38662cb0",
      "userId": 123,
      "email": "user@example.com",
      "username": "johndoe",
      "firstName": "John",
      "lastName": "Doe",
      "kycProvider": "GOOGLE",
      "contractId": "contract::123",
      "metadata": {
        "emailVerified": true,
        "profilePicture": "https://example.com/avatar.jpg"
      }
    },
    {
      "partyId": "party::12200d35764b9b490251e499af00626b54516c4f3f1c021c2eb72bf7c72f38662cb0",
      "userId": 123,
      "email": "user@example.com",
      "username": "johndoe",
      "kycProvider": "GITHUB",
      "contractId": "contract::456",
      "metadata": {
        "githubFollowers": 150,
        "githubRepos": 25
      }
    }
  ]
}

Usage Notes

• Forward lookup (q option): Search is case-insensitive and matches against both email and username fields
• Reverse lookup (partyId option): Returns all credentials associated with the party ID across all providers
• Only returns credentials that the institution has approved access to
• Returns empty array if no matches found
• Can return multiple credentials if user has multiple providers
• Throws an error if both q and partyId are provided, or if neither is provided

Note

The SDK also provides convenience methods `resolve(query)` and `reverseResolve(partyId)` for simpler use cases. For additional details including request headers, query parameters, and cURL examples, see the corresponding endpoint in the API Reference section.
