Interactive PDF Presentation

Code Example `js // Node.js example using fetch (Node 18+). Nadia, backend engineer, uses this in a service layer.

import { setTimeout as delay } from "node:timers/promises";

const baseUrl = "https://api.interactive-pdf.example.com/v1"; const apiKey = process.env.INTERACTIVE_PDF_API_KEY; // e.g., set in your deployment environment

if (!apiKey) { throw new Error("Missing INTERACTIVE_PDF_API_KEY"); }

async function createPresentation(payload) { const res = await fetch(${baseUrl}/presentations, { method: "POST", headers: { // Required authentication format Authorization: Bearer ${apiKey}, "Content-Type": "application/json", }, body: JSON.stringify(payload), // Optional: enforce client-side timeout via AbortController in production code });

// Error handling: non-2xx responses include JSON error payloads (see Response Format) const json = await res.json().catch(() => ({})); if (!res.ok) { const msg = json?.error?.message || HTTP ${res.status}; throw new Error(msg); }

return json; }

// Example payload shape depends on your presentation creation contract. const presentation = await createPresentation({ title: "Quarterly Results", source: { type: "pdf", uri: "https://storage.example.com/input.pdf" }, }); console.log(presentation.presentationId); `

Response Format json { "requestId": "req_01J2...Z9", "presentationId": "pres_01J2...AB", "status": "created", "expiresAt": "2026-04-05T12:34:56Z", "error": null }

Error payload (non-2xx) json { "requestId": "req_01J2...Z9", "error": { "code": "unauthorized", "message": "Invalid or missing API key", "details": { "header": "Authorization", "expected": "Bearer " } } }

Notes & Best Practices - Never log secrets: redact Authorization in application logs and error traces (including HTTP client debug output). - Environment variable precedence: use INTERACTIVE_PDF_API_KEY as the source of truth; do not hardcode keys in code or CI scripts. - Handle 401/403 precisely: 401 typically indicates missing/invalid key; 403 indicates key lacks required permissions for the endpoint. - Validate key format: ensure the header is exactly Bearer (case-sensitive prefix, no extra whitespace).

With authentication in place, the next chapter covers how to send authenticated request payloads to create interactive presentations and wire them to your rendering workflow.
