@visionfi/server

Server-side SDK for VisionFI API access using Google Service Account authentication.

Installation

npm install @visionfi/server

Quick Start

import { VisionFi } from '@visionfi/server';

// Initialize with service account
const client = new VisionFi({
  serviceAccountPath: './service-account.json'
});

// Or use Application Default Credentials
const client = new VisionFi();

// Verify authentication
const auth = await client.verifyAuth();

// Create a package
const pkg = await client.createPackage({
  productType: 'consumer_loan_vehicle',
  description: 'Vehicle loan application'
});

// Analyze a document
const job = await client.analyzeDocument(fileBuffer, {
  fileName: 'document.pdf',
  analysisType: 'auto_loan_abstract'
});

// Get results
const results = await client.getResults(job.uuid);

Authentication

This package supports three authentication methods:

1. Service Account File: Provide path to JSON key file
2. Service Account JSON: Pass JSON object directly
3. Application Default Credentials: Automatic in GCP environments

Features

• Document analysis and processing
• Package management
• Package sharing with role-based permissions
• DocuSign integration
• Workflow management
• Processing history and results
• Per-request custom headers for B2B2C scenarios

Package Sharing

The SDK supports sharing packages with other users with role-based permissions.

Share a Package

// Share with specific users
await client.packages.sharing.addShares('package-uuid', [
  { target: '[email protected]', role: 'editor' },
  { target: '[email protected]', role: 'viewer' }
]);

// Share with all users in your organization
await client.packages.sharing.addShares('package-uuid', [
  { target: 'AllUsers', role: 'viewer' }
]);

Update Share Role

await client.packages.sharing.updateRole('package-uuid', '[email protected]', 'viewer');

Remove a Share

await client.packages.sharing.remove('package-uuid', '[email protected]');

Get Sharing Info (Owner Only)

const info = await client.packages.sharing.getInfo('package-uuid');
// { packageId, owner, shares: [{ target, role }] }

List Packages Shared With Me

const shared = await client.packages.listShared();
// { packages: [{ packageId, owner, myRole, sharedVia, ... }], total }

List All Accessible Packages

// List only owned packages (default)
const owned = await client.packages.list();

// List only shared packages
const shared = await client.packages.list({ include: 'shared' });

// List all accessible packages (owned + shared)
const all = await client.packages.list({ include: 'all' });

Per-Request Custom Headers

All SDK methods support an optional requestOptions parameter that allows you to pass custom headers on a per-request basis. This is useful for B2B2C scenarios where you need to identify the end-user making the request.

Example: Passing End-User Identity

import { VisionFi } from '@visionfi/server';

const client = new VisionFi();

// Pass end-user identity via VF-On-Behalf-Of header
const packages = await client.packages.list(
  { productTypes: 'consumer_loan_vehicle' },
  { headers: { 'VF-On-Behalf-Of': '[email protected]' } }
);

// Works with all SDK methods
const pkg = await client.packages.get(
  'package-uuid',
  { headers: { 'VF-On-Behalf-Of': '[email protected]' } }
);

// Create package on behalf of user
const newPkg = await client.packages.create(
  { productType: 'consumer_loan_vehicle' },
  { headers: { 'VF-On-Behalf-Of': '[email protected]' } }
);

// Execute processing on behalf of user
const result = await client.packages.processing.execute(
  'package-uuid',
  { workflow: 'auto_loan_abstract' },
  { headers: { 'VF-On-Behalf-Of': '[email protected]' } }
);

Protected Headers

For security, the following headers cannot be overridden per-request and will be stripped:

• authorization - Managed by SDK authentication
• host - Managed by axios
• x-api-key - Managed by SDK configuration
