healthassure-messaging

healthassure-messaging is a typed Python SDK for durable business-messaging orchestration. It provides provider-neutral requests, explicit provider routing, consent and session policy ports, idempotent dispatch state, and optional Mongo persistence. A Meta Cloud API provider and Meta delivery-webhook parser are included.

Stable version 1.1.0 requires Python 3.10 through 3.13.

Installation

python -m pip install healthassure-messaging

Install the optional caller-owned Mongo persistence adapter with:

python -m pip install 'healthassure-messaging[mongo]'

Provider-neutral orchestration

from healthassure_messaging import (
    FakeMessagingProvider,
    MessagingGateway,
    MessagingService,
    ProviderRegistry,
    SendDisposition,
)

Applications supply policy, session, template, and intent ports to MessagingService. Provider selection is explicit: the service does not retry or fall back to another provider automatically. Requests are serialized with schema version 2 before a claimed dispatch. Schema-version-1 requests remain strictly readable for persisted compatibility.

The optional MongoMessagingPersistence accepts a caller-owned PyMongo Database handle. It never creates a client, loads credentials, reads settings, or connects during import. Index creation occurs only through an explicit ensure_indexes() call. Policy and session event arrays are intentionally unbounded in this release; production adopters need an archival or compaction design. Mongo command construction is covered with deterministic fakes, while real-server atomicity and index compatibility remain an integration evidence gate for adopters.

Supported external platform

The included MetaCloudProvider supports outbound text and template requests to the Meta WhatsApp Business Platform, plus signature verification and delivery status parsing for Meta webhook payloads. Consumers own credentials, configuration, consent records, template mappings, routing, and operational controls. The library makes no provider or database call during import.
