What this skill does
Apollo Local Dev Loop Overview Set up an efficient local development workflow for Apollo.io integrations. Includes sandbox API key support, MSW mock server for offline testing, request logging, and npm scripts for daily development. Apollo provides a sandbox API token that returns dummy data without consuming credits. Prerequisites Completed apollo-install-auth setup Node.js 18+ Git repository initialized Instructions Step 1: Set Up Environment Files Apollo offers a sandbox token for testing. Generate one at Settings > Integrations > API Keys > Sandbox. Step 2: Create a Dev Client with Request Logging Step 3: Set Up MSW Mock Server for Offline Testing Step 4: Configure Vitest Step 5: Add Development Scripts Output .env.example template with sandbox key support Dev client with request/response logging and rate-limit display MSW mock handlers for people search, enrichment, org enrichment, and sequences Vitest config with mock server setup/teardown npm scripts for dev, test, sandbox testing, and credential checks Examples For a new people-search change, run the MSW-backed unit suite first and assert only synthetic fixture fields. Enable the sandbox key only for the narrow connectivity check after the mock suite passes, with APOLLOUSESANDBOX=true set explicitly in the command environment. Review logs for endpoint, status, and request-field names—not contact values, API keys, or full error payloads. If the sandbox key is absent, the mock server is bypassed, or any live-credit path is selected unexpectedly, stop the run and restore the mock-only setup before continuing development. …
