pingencom/pingen2-sdk-php

This is a PHP client SDK for Pingen’s document-delivery API. A typical integration obtains an OAuth access token, configures a resource endpoint for an organisation and environment, then submits documents or manages delivery resources; the SDK sends authenticated JSON:API requests and maps responses into typed DTOs. The API surface also covers batches, letters, email, e-bills, events, uploads, organisations, users, and webhooks. Source excerpts show the shared request layer and webhook handling; most endpoint implementations are unsampled, so their detailed call relationships are not asserted.
