Supported Connectors

Leen.dev Unified API for Security

Introduction

Quick Start

OnRamp is Leen's embeddable onboarding component that allows your users to easily create new connections or update existing connections. As an embeddable component, OnRamp is designed to be integrated directly into your application workflow.

Create a connection

Update a connection

Authentication

Due to a limitation in our docs it has become confusing to figure out how to create a new connection. This guide will help you through the process.

Creating a new connection

The Leen API supports cursor-based pagination to help you efficiently navigate through large datasets. Follow these steps to implement pagination using our API.

Cursor Pagination

The Connection Health feature provides a high-level view of connection stability by evaluating the status of the most recent job run. It helps identify unhealthy connections, categorize failure types, and improve error visibility.

Connection Health

Supported AppSec connectors for the AppSec endpoints

AppSec Connectors

List all the issues for a given connection. sort - supports `severity:asc` (eg. lowest to highest criticality) and `severity:desc` if not direction is provided it will default to `asc`

List vulnerability findings with keyset pagination and filtering options.

- **severity**: Filter by severity (comma-separated list, e.g., 'CRITICAL,HIGH')
- **state**: Filter by state (comma-separated list, e.g., 'OPEN,REOPENED')
- **has_fix**: Filter by whether a fix is available
- **first_seen_since**: Filter by findings first seen after this date
- **last_seen_since**: Filter by findings last seen after this date
- **state_updated_since**: Filter by findings with state updated after this date
- **resourceId**: Filter by resource ID (comma-separated list)
- **ids**: Filter by finding IDs (comma-separated list of UUIDs, max 100)
