Step 1: Detect stack and install SDK

Detect the project's language/framework from existing files (package.json, requirements.txt, go.mod, pom.xml) and install accordingly:

Stack	Install command
Node.js	npm install @scalekit-sdk/node
Python	pip install scalekit-sdk
Go	go get github.com/scalekit/scalekit-go
Java	Add com.scalekit:scalekit-sdk to pom.xml or build.gradle

---

Step 2: Environment credentials

Add to .env (never hardcode):

SCALEKIT_ENVIRONMENT_URL='https://<your-env>.scalekit.com'
SCALEKIT_CLIENT_ID='<CLIENT_ID>'
SCALEKIT_CLIENT_SECRET='<CLIENT_SECRET>'
SCALEKIT_WEBHOOK_SECRET='<WEBHOOK_SECRET>'

Credentials are found in Dashboard > Developers > Settings > API Credentials. Webhook secret is found in Dashboard > Webhooks after registering an endpoint.

---

Step 3: Initialize the Scalekit client

Insert initialization near the app's startup or service layer — match the project's existing patterns (singleton, DI, module export, etc.).

Node.js:

import { ScalekitClient } from '@scalekit-sdk/node';
const scalekit = new ScalekitClient(
  process.env.SCALEKIT_ENVIRONMENT_URL,
  process.env.SCALEKIT_CLIENT_ID,
  process.env.SCALEKIT_CLIENT_SECRET
);

Python:

from scalekit import ScalekitClient
scalekit_client = ScalekitClient(
    env_url=os.getenv("SCALEKIT_ENVIRONMENT_URL"),
    client_id=os.getenv("SCALEKIT_CLIENT_ID"),
    client_secret=os.getenv("SCALEKIT_CLIENT_SECRET")
)

For Go and Java patterns, see REFERENCE.md.

Step 4: Directory API (on-demand sync)

Use for scheduled jobs, onboarding flows, or bulk imports. Integrate into existing user service/repository layer — do not create a parallel user management path.

Fetch users and sync:

// Node.js
const { directory } = await scalekit.directory.getPrimaryDirectoryByOrganizationId(orgId);
const { users } = await scalekit.directory.listDirectoryUsers(orgId, directory.id);

for (const user of users) {
  await upsertUser({ email: user.email, name: user.name, orgId });
}

# Python
directory = scalekit_client.directory.get_primary_directory_by_organization_id(org_id)
users = scalekit_client.directory.list_directory_users(org_id, directory.id)

for user in users:
    upsert_user(email=user.email, name=user.name, org_id=org_id)

Group sync for RBAC:

const { groups } = await scalekit.directory.listDirectoryGroups(orgId, directory.id);
for (const group of groups) {
  await syncGroupPermissions(group.id, group.name);
}

Plug upsertUser / syncGroupPermissions into the project's existing user/role management functions — identify them by searching for createUser, updateUser, or equivalent patterns in the codebase.

---

Step 5: Webhook endpoint (real-time provisioning)

Add a new route to the existing HTTP server/router. Match the framework pattern already in use (Express, FastAPI, Spring Boot, net/http, etc.).

ALWAYS verify the signature before processing. Return 400 on failure.

Node.js (Express):

app.post('/webhooks/scalekit', async (req, res) => {
  try {
    await scalekit.verifyWebhookPayload(
      process.env.SCALEKIT_WEBHOOK_SECRET,
      req.headers,
      req.body
    );
  } catch {
    return res.status(400).json({ error: 'Invalid signature' });
  }

  const { type, data } = req.body;
  try {
    await handleDirectoryEvent(type, data);
    res.status(201).json({ status: 'processed' });
  } catch (err) {
    res.status(500).json({ error: 'Processing failed' });
  }
});

Python (FastAPI):

@app.post("/webhooks/scalekit")
async def scalekit_webhook(request: Request):
    body = await request.json()
    valid = scalekit_client.verify_webhook_payload(
        secret=os.getenv("SCALEKIT_WEBHOOK_SECRET"),
        headers=request.headers,
        payload=json.dumps(body).encode()
    )
    if not valid:
        raise HTTPException(status_code=400, detail="Invalid signature")

    await handle_directory_event(body.get("type"), body.get("data", {}))
    return JSONResponse(status_code=201, content={"status": "processed"})

For Go and Java, see REFERENCE.md.

Step 6: Event handler

Create a single dispatcher that routes to existing user operations. Map events to the project's existing create/update/deactivate functions:

async function handleDirectoryEvent(type, data) {
  switch (type) {
    case 'organization.directory.user_created':
      return createUser(data.email, data.name, data.organization_id);
    case 'organization.directory.user_updated':
      return updateUser(data.email, data.name);
    case 'organization.directory.user_deleted':
      return deactivateUser(data.email); // prefer deactivate over hard delete
    case 'organization.directory.group_created':
    case 'organization.directory.group_updated':
      return syncGroup(data);
    default:
      console.log(`Unhandled event: ${type}`);
  }
}

Prefer deactivation over deletion for user_deleted events unless the project explicitly hard-deletes users.

Step 7: Dashboard registration checklist

After deploying the webhook endpoint:

1. Go to Dashboard > Webhooks > +Add Endpoint
2. Enter the public HTTPS URL: https://your-app.com/webhooks/scalekit
3. Subscribe to events:
   • organization.directory.user_created
   • organization.directory.user_updated
   • organization.directory.user_deleted
   • organization.directory.group_created
   • organization.directory.group_updated
4. Copy the webhook secret into SCALEKIT_WEBHOOK_SECRET
5. Share the SCIM setup guide with the customer's IT admin for their IdP-specific directory sync steps.

Guardrails

• Never hardcode credentials — always process.env / os.getenv / System.getenv
• Idempotent operations — upsertUser must handle duplicate events safely
• Return 2xx quickly — offload heavy processing to a queue if needed; Scalekit retries on non-2xx with exponential backoff (up to 8 attempts over ~10 hours)
• Validate signatures — every webhook request, every time
• Deactivate, don't delete — unless codebase explicitly hard-deletes users
