## Connecting Custom, On-Premise, and Niche Tools

For internal scripts, proprietary client databases, or tools without a pre-built connector:

- Use the **[HTTP Request](/build/action-steps/http-request)** step with instant cURL command import.
- Store sensitive tenant credentials in workspace **[Secrets](/manage/workspace-settings/secrets-and-variables)** for strict per-client isolation.
- Ingest live alert streams using the **[Webhook Trigger](/build/triggers/webhook)** with cryptographic HMAC SHA-256 signature verification.

## What's Next?

👉 **[Automation Blueprints →](/msp/automation-blueprints)** — turn these connection methods into example client workflows.

Sideways from here: [Supported Integrations](/msp/msp-integrations) explains when to use an app connection, HTTP Request, or webhook.
