# Leadping API Reference

> Use Leadping endpoint schemas, examples, authentication guidance, SDKs, and the public OpenAPI specification.

The Leadping REST API provides access to leads, sources, conversations, automations, phone numbers, messages, calls, billing, and operational records.

Endpoint pages in this reference are generated from the Leadping OpenAPI specification and contain current paths, parameters, request bodies, response models, status codes, and examples.

## Before making a request

1. Choose the correct identity and credential in [API Authentication](/docs/api-authentication).
2. Use a source key only for the external lead-ingestion routes.
3. Select direct HTTP or a generated [Leadping SDK](/docs/sdks/overview).
4. Implement status-code handling and [rate-limit](/docs/rate-limits) backoff.
5. Test with controlled data before enabling production traffic.

## OpenAPI specification

Use the public [OpenAPI JSON document](/docs/openapi.json) to generate clients, validate contracts, or connect OpenAPI-compatible tooling.

For source-authenticated lead posting, begin with [Send Leads with the Intake API](/docs/sending-leads-to-leadping). Intake has source-specific authentication, TrustedForm, and validation requirements.
