Code Examples

SDK examples in popular languages

Python SDK

python

from datametric import DataMetricClient

# Initialize the client
client = DataMetricClient(
    api_key="your-api-key",
    endpoint="https://api.datametric.io"
)

# Register a dataset
dataset = client.datasets.create(
    name="customers",
    source="postgres",
    description="Customer master data"
)

# Track lineage
client.lineage.track(
    upstream="raw.customers",
    downstream="cleaned.customers"
)

TypeScript SDK

typescript

import { DataMetric } from '@datametric/sdk';

const client = new DataMetric({
  apiKey: process.env.DATAMETRIC_API_KEY,
  environment: 'production'
});

// Query metadata
const datasets = await client.datasets.list({
  filter: { domain: 'finance' },
  include: ['lineage', 'owners']
});

// Create a data policy
await client.policies.create({
  name: 'PII Access Control',
  rules: [{
    field: 'contains_pii',
    action: 'restrict',
    roles: ['analyst']
  }]
});

Security & Compliance

Security Best Practices

Keep your data governance platform secure

Use API Keys

Rotate API keys regularly and never expose them in client-side code.

Enable SSO

Configure SAML or OIDC for single sign-on with your identity provider.

Audit Logging

Enable comprehensive audit logging for compliance and security monitoring.

Network Policies

Restrict access to your DataMetric instance using IP allowlists and VPN requirements.

Everything you need to succeed
