As such, it is the ideal tool for building alternative dashboards, developing mobile applications and automating front and back-end applications. ## Development environments and endpoints DIDWW maintains both a sandbox and a production environment for the API. While both environments are perfect replicas of one another, they are maintained separately so as not to interfere with your live data. This structure provides your developers with full access to extensive testing for unlimited time before rolling out your services to production.

DIDWW offers official SDKs for PHP, Java, Python, TypeScript, Go, and .NET, so developers can integrate the REST API into their own applications without building requests from scratch. The API itself follows the JSON API specification for consistent, predictable responses across all endpoints. ### Is there a sandbox environment to test before going live? Yes. DIDWW maintains a sandbox environment that mirrors production, letting you test number ordering, trunk configuration, and call event handling without affecting live data or billing. Sandbox API keys are issued by Technical Support on request. ### Are there rate limits on API requests? Yes. Each API key is limited to 20 requests per second. Exceeding this returns an HTTP 429 “Too Many Requests” response. ### What can I automate with the DIDWW API? You can order and configure [phone numbers](https://www.didww.com/phone-numbers/all-phone-numbers), manage [SIP trunks](https://www.didww.com/voice/global-sip-trunking) and [Capacity](https://www.didww.com/services/capacity), submit end-user verification documents, export call data, and receive real-time call events, covering most tasks otherwise done manually in the User Panel.
