The anymail.webhooks subsystem provides a flexible and extensible framework for handling incoming webhook events from various Email Service Providers (ESPs). At its core, anymail.webhooks.base establishes an abstract interface and a common processing pipeline, ensuring consistent handling of webhook requests. This base component delegates the ESP-specific parsing and validation to a set of anymail.webhooks.ConcreteProcessors. Each concrete processor acts as an adapter, extending the base interface to implement the unique logic required for its respective ESP, transforming raw webhook data into standardized django-anymail event objects. This design promotes modularity, allowing new ESP integrations to be added by simply implementing a new concrete processor that adheres to the defined base interface.
This component defines the abstract interface and the common processing flow for all ESP webhook handlers. It acts as the central orchestrator, providing a consistent API (validate_request, parse_events, post) that all concrete webhook processors must adhere to. It ensures that regardless of the ESP, the initial handling and dispatching of webhook events follow a predictable pattern.

This conceptual component represents the collection of concrete implementations, each designed as an adapter for a specific Email Service Provider (e.g., Amazon SES, Brevo, Mailgun, SendGrid, etc.). Each concrete processor is responsible for the ESP-specific logic of receiving, validating (if applicable), and parsing the raw incoming webhook data. Their primary role is to transform the ESP's unique data format into standardized django-anymail event objects (AnymailEvent) and, in some cases, handle inbound email messages or attachments.
