# DIDWW API v3 Documentation - v2026-04-16 (Latest)

The DIDWW API v3 is a REST-based service for integrating your applications with DIDWW services.
It allows you to manage phone numbers, configure services, set capacities, create SIP trunks, and retrieve call detail
records (CDRs) and other operational data.

Use the API from your backend to build custom dashboards and automate service management.
Keep API keys out of browser and mobile application code. See [Authentication](authentication.html)
and the [Sandbox guide](../sandbox.html) before sending your first request.

The API follows the [JSON:API](https://jsonapi.org/format/) specification for resource
requests and responses. Use the [OpenAPI Reference](api-reference.html) to check the
methods, parameters, and response schemas supported by each endpoint.

Note

This documentation assumes familiarity with web programming concepts, JSON data formats, and the JSON API specification.
For additional details, refer to the [JSON API official website](https://jsonapi.org/format/).
