Webhooks & Change Notifications

Stay informed when the data you care about changes.

Webhook Subscriptions

Create subscriptions that trigger when:

• A specific entity is updated
• New entities match a saved query
• Status changes on trials you're tracking
• Regulatory actions affect drugs in your portfolio

Easy Setup

1. Go to Settings → Webhooks
2. Add your endpoint URL
3. Choose which events to subscribe to
4. We'll send a test payload to verify

Retry Logic

Failed deliveries are retried with exponential backoff:

• 1 minute, 5 minutes, 30 minutes, 2 hours, 24 hours
• After 5 failures, the webhook is paused
• View delivery logs and manually retry from the dashboard
