PostGrid Node.js Client

The `postgrid-node-client` library provides a Node.js and TypeScript client for interacting with the PostGrid Business API, facilitating postal delivery services (Print-Mail) and address verification/autocomplete. Currently at version 0.11.0, this package offers a convenient, typed interface over PostGrid's dual REST API structure. A key differentiator is its robust handling of two distinct API keys required by PostGrid: one for Print-Mail and another for Address Verification, allowing developers to instantiate a single client that intelligently routes requests. While a specific release cadence isn't published, its pre-1.0 versioning implies active development. The client simplifies common tasks such as creating contacts, sending documents, and verifying addresses, abstracting away direct HTTP requests and JSON parsing, and supports webhook configuration for event notifications.
