Getting Started

Sign up for free at the RocketStack console. No credit card required.

Once logged in, you'll see the developer console. Here's what you'll find:

All six primitives are available on the free tier with generous quotas for development.

To subscribe to an API with expanded limits:

1. Go to API Catalog in the console
2. Click on the API you want to use
3. Click Subscribe to add it to your account

Create an application to get your API key for authentication.

1. Navigate to Applications in the sidebar
2. Click Create Application
3. Enter a name (e.g., "My App - Development")
4. Copy your API key immediately

ROCKETSTACK_API_KEY=rs_live_xxxxxxxxxxxx

Let's store a value in KV to test your setup. Replace the API key with your own.

curl -X PUT https://api.rocketstack.dev/kv/items/user-123 \
  -H "Authorization: Bearer rs_live_xxxx" \
  -H "Content-Type: application/json" \
  -d '{"value": {"name": "John", "email": "john@example.com"}}'

{
  "requestId": "...",
  "data": { "key": "user-123", "version": "...", "expiresAt": null }
}

That's it! You've successfully stored data in RocketStack. Explore the full API reference →
