Connect to Marketing APIs in Minutes
Just like Plaid for banking, we handle OAuth for marketing platforms. Stop building authentication flows from scratch. Datagran Auth manages tokens, webhooks, and data proxying for Facebook Ads, Google Ads, and more.
const token = await datagran.createLinkToken(({
userId: "user_123",
email: "user@company.com"
});
// User authenticates with Facebook
DatagranLink.open(({ linkToken: token });
// Fetch data without touching tokens
const campaigns = await datagran.getCampaigns((connectionId);How It Works

Why Datagran Auth
Enterprise-grade security and reliability
Secure Token Storage
AES-256-GCM encryption at rest. Your users' tokens are never exposed.
5-Minute Setup
Register, embed widget, fetch data. No OAuth expertise required.
Auto Token Refresh
We monitor token health and refresh automatically. No downtime.
Unified API
One API for all platforms. Switch providers without changing code.
Webhooks
Real-time notifications for connections, errors, and token issues.
Production Ready
Rate limiting, error handling, and monitoring built-in.
Bank-Level Security
Your users trust you with their data. We protect it like our own.
AES-256-GCM Encryption
All OAuth tokens are encrypted at rest using military-grade AES-256-GCM encryption. Each token has its own unique initialization vector and authentication tag for maximum security.
Zero Token Exposure
Tokens never touch your application or frontend. All API requests go through our secure data proxy—your partners only receive the data they need, never the raw credentials.
PKCE OAuth Flow
We implement OAuth 2.0 with PKCE (Proof Key for Code Exchange) to prevent authorization code interception attacks. Every auth session has unique challenge/verifier pairs.
API Key Hashing
Partner API keys are hashed with bcrypt (10 rounds) before storage. We never store plain-text keys—even we can't see your partners' credentials after creation.
Origin Whitelisting
Strict CORS enforcement and origin validation. The auth widget only opens from pre-approved domains, preventing unauthorized access attempts and phishing attacks.
Audit Logs
Complete audit trail of all authentication events, token refreshes, and API access. Track every action for compliance and security monitoring.
Data Deletion & Compliance
Full GDPR compliance with automated data deletion workflows. When users disconnect or delete their accounts, we automatically revoke tokens and purge all related data from our systems.
