# Product Requirements Document (PRD) ## Product: **Binect-JS API Wrapper** --- ## 1. Product Overview ### 1.1 Product Name **Binect-JS API Wrapper** (working title; final package naming is out of scope for this PRD) ### 1.2 Product Intent Binect-JS is a **developer-facing integration product** that enables JavaScript developers to **interact reliably and intuitively with the Binect API** to send PDF documents as physical mail. The product’s primary intent is to **lower the cognitive, technical, and experiential barrier** for first-time and recurring users of the Binect API—especially in browser-based and JavaScript-centric environments—without changing the underlying Binect service. ### 1.3 Problem Statement While the Binect API provides comprehensive functionality for physical mail dispatch, it presents several challenges to developers: * The API is **low-level and REST-centric**, requiring significant upfront interpretation. * Developers must manually handle: * authentication * base64 encoding * document lifecycle states * error interpretation * There is no **official JavaScript abstraction** or **exploratory tooling** that supports learning, testing, and safe experimentation. As a result, developers face: * higher onboarding friction * increased implementation errors * duplicated integration effort across projects --- ## 2. Target Users and Stakeholders ### 2.1 Primary Users * JavaScript and TypeScript developers * Frontend developers integrating physical mail into web applications * Full-stack developers building document workflows * Solution engineers evaluating Binect for customer projects ### 2.2 Secondary Stakeholders * Product management (Binect ecosystem) * Technical sales and pre-sales * Developer support and onboarding teams * Partner developers building reusable integrations --- ## 3. Product Goals ### 3.1 Primary Goals * **Reduce integration effort** for JavaScript developers using the Binect API * **Increase correctness and reliability** of API usage * **Improve discoverability** of Binect API capabilities * **Support rapid experimentation** without backend infrastructure ### 3.2 Secondary Goals * Serve as a **reference integration** for good API usage patterns * Act as a **learning surface** for understanding document validation and sending workflows * Provide a **shared vocabulary and structure** for downstream tooling and documentation --- ## 4. Scope ### 4.1 In Scope #### Functional Expectations (Conceptual) * Enable JavaScript-based interaction with the Binect API for: * uploading PDF documents * inspecting document readiness and validation state * modifying document-related parameters * triggering physical mail dispatch * observing sending status and outcomes * Provide an **interactive, browser-based explorer** that: * allows credential input * allows safe execution of API calls * visualizes results in both structured and raw form * supports reusable, named “use case profiles” #### Usage Context * Usable as: * a **local developer tool** * a **hosted static web application** * Applicable to: * exploratory usage * prototyping * production integration support ### 4.2 Explicit Non-Scope * No redesign or modification of the Binect backend API * No replacement of backend integrations or enterprise workflows * No PDF generation, editing, or layout tooling * No scheduling, batching, or business process orchestration * No commitment to a specific UI framework or architectural pattern --- ## 5. Assumptions and Constraints ### 5.1 Assumptions * The Binect API is accessible via HTTPS using Basic Authentication * API access is permitted directly from browser environments (no CORS restriction) * Users possess valid Binect credentials * Developers have access to PDFs already prepared for sending ### 5.2 Constraints * The product must operate **without server-side components** * Sensitive information must not be stored unintentionally * The wrapper must not obscure or reinterpret business-critical API semantics * The product must remain compatible with future Binect API evolution --- ## 6. Success Criteria ### 6.1 Qualitative Success Indicators * Developers can complete a “send physical mail” workflow **without consulting raw API documentation** * First-time users can validate and preview documents before sending * The Explorer is usable as a **learning tool**, not just a test harness * API errors are understandable and actionable ### 6.2 Quantitative / Observable Indicators * Reduction in support inquiries related to JavaScript integrations * Decreased integration time reported by developers * Reuse of the wrapper across multiple projects or partners * Adoption of Explorer during onboarding or demos --- ## 7. Non-Functional Expectations ### 7.1 Usability * Clear mental mapping between user actions and API effects * Safe defaults that prevent accidental mail dispatch * Transparent presentation of API responses ### 7.2 Reliability * Predictable handling of network and API errors * Explicit representation of document and sending states ### 7.3 Security & Trust * Credentials handled with care and minimal persistence * No hidden data transmission or telemetry * Clear user control over destructive actions (send, cancel, delete) ### 7.4 Maintainability * Product intent remains stable even as API details evolve * Wrapper serves as a single adaptation layer for API changes --- ## 8. Dependencies and External Interfaces ### 8.1 External Dependencies * Binect REST API * Browser and JavaScript runtime capabilities (fetch, crypto, storage) ### 8.2 Downstream Artifacts This PRD intentionally precedes and informs: * Functional Requirements Specification (FRS) * Technical Design Documents (TDD) * Architecture Decision Records (ADR) * SDK and Explorer implementation plans --- ## 9. Risks and Mitigations | Risk | Impact | Mitigation | | ------------------------ | -------------------- | -------------------------------------------------- | | API behavior changes | Integration breakage | Wrapper as adaptation layer | | Over-abstracting API | Loss of control | Keep wrapper thin and transparent | | Accidental mail dispatch | User trust erosion | Explicit confirmations and preview-first workflows | | Scope creep | Delayed delivery | Strong adherence to PRD boundaries | --- ## 10. PRD Variant Classification This document represents a **Hybrid / Boundary PRD**: * Sufficiently precise to anchor engineering decisions * Flexible enough to accommodate iterative refinement * Explicitly positioned between product intent and implementation design --- ## 11. Traceability Note This PRD acts as the **intent anchor** for all downstream decisions. Any architectural or technical decision should be explainable as a consequence of: > “Enabling safe, intuitive JavaScript access to the Binect API for document-based physical mail workflows.”
