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:
