# Developers introduction

> How to integrate with Airlead as a source, buyer, or Connect partner.

# Developers introduction

Airlead integrates with source and buyer systems through HTTPS JSON webhooks. Choose the guide by the direction in which lead data moves.

## Base URL

Production:

```text theme={null}
https://app.airlead.de
```

Use the environment-specific host provided by Airlead for staging or testing.

## Integration principles

* Treat IDs as opaque strings.
* Send and accept `application/json`.
* Use TLS for every request.
* Store secrets outside source code and logs.
* Use stable external IDs for ingest retries.
* Store transaction IDs for lifecycle callbacks.
* Retry transient failures with exponential backoff and jitter.
* Do not retry validation or authentication failures without correcting the request.

## Public vs. in-app endpoints

This documentation covers supported partner webhook endpoints. The Airlead web app also uses session-authenticated endpoints internally. Those endpoints are not a public integration contract unless they appear in this documentation and the OpenAPI specification.
