Best prompts for ChatGPT for coding using integrating third-party APIs

Create a production-ready Node.js (Express) implementation of the OAuth2 Authorization Code flow for GitHub. Requirements: - Use environment variables: GITHUB_CLIENT_ID, GITHUB_CLIENT_SECRET, REDIS_URL. - Implement routes: GET /auth/github -> redirect to GitHub with scope 'read:user' and a cryptographically-random state stored in Redis; GET /auth/github/callback -> validate state, exchange code at https://github.com/login/oauth/access_token (accept JSON), fetch user profile from https://api.github.com/user using the returned token. - Use axios or node-fetch for HTTP calls, crypto for state, and ioredis for Redis. - Encrypt OAuth tokens before saving to Redis (show encryption key handling via env var), set cookie-based session with HttpOnly and Secure flags. - Add robust error handling, logging comments, and sample unit tests (Jest) for the callback handler using nock to mock GitHub responses. Return code files, a short explanation of security decisions, and example curl commands to test the flow.

Generate a TypeScript wrapper module for Stripe with strict types and small helper functions. Requirements: - Provide functions: createPaymentIntent(amount:number, currency:string, customerId?:string): Promise<PaymentIntentResult>, getCustomer(customerId:string): Promise<CustomerResult>. - Use the official stripe npm package but convert returned objects to simplified typed interfaces. - Implement centralized error mapping (e.g., map Stripe errors to custom Error classes with status codes). - Include an example Next.js API route showing how to use the wrapper with environment variable STRIPE_SECRET_KEY and proper error responses. - Provide unit tests (Vitest) that mock stripe responses and a short README explaining where to place keys and how to extend the wrapper.

Provide a robust Express webhook handler for Stripe that verifies signatures and prevents duplicate processing. Requirements: - Implement POST /webhooks/stripe using raw body parsing (show middleware configuration). - Use STRIPE_WEBHOOK_SECRET to verify via stripe.webhooks.constructEvent. - Handle event types: payment_intent.succeeded, charge.refunded, checkout.session.completed. - Persist processed event IDs to PostgreSQL (upsert) to ensure idempotency and show SQL schema. - Demonstrate how to run the handler in AWS Lambda (using aws-serverless-express or a minimal adapter) and how to test locally with a curl sample and a mocked stripe signature header. - Explain replay protection and recommended TTL for stored event IDs.

Produce a Python implementation of a retry/backoff decorator for async HTTP calls. Requirements: - Implement @http_retry(max_attempts=5, base_delay=0.5, max_delay=10, statuses=[429,502,503,504], retry_on_exception=(httpx.TimeoutException,)) for async functions that perform HTTPX requests. - Use exponential backoff with full jitter, and expose an on_retry callback hook for logging. - Optionally integrate a simple circuit-breaker using aioredis to store fail counts (provide pseudocode toggled by a flag). - Include an example async function fetch_data() calling https://api.example.com/v1/items and tests (pytest + respx) that simulate failures and assert that the decorator retries as expected. - Explain recommended max_attempts and behavior for 429 with Retry-After header.

Create a Node.js Apollo Server resolver that exposes a GraphQL connection for a third-party REST endpoint that uses page + page_size pagination. Requirements: - Implement cursor encoding/decoding (base64 of JSON {page,index}). - For a request itemsConnection(first: Int, after: String), calculate which REST pages to fetch to fulfill 'first' items with minimal calls. - Return edges [{ cursor,node }] and pageInfo { hasNextPage, endCursor }. - Provide helper code to translate REST items into GraphQL nodes, handle total count, and include an example resolver for GET https://api.example.com/items. - Add unit tests demonstrating fetching across page boundaries (use nock to mock REST responses).

Design and implement an API key rotation workflow using AWS Secrets Manager for a third-party service. Requirements: - Provide a Node.js AWS Lambda rotateKey.js that: calls the vendor's key creation endpoint (example vendor: https://admin.example.com/api/keys), stores the new key in Secrets Manager, and archives old keys. - Show how consuming Lambdas should fetch secrets securely (via AWS SDK), cache in-memory with TTL, and automatically refresh when secret version changes (show example code that polls Secrets Manager or subscribes to a rotation SNS topic). - Include recommended IAM policies for rotation Lambda and consumers, a short CloudFormation (or CDK) snippet to create the secret and Lambda trigger (cron), and considerations for key propagation and rolling updates.
