​
Setup

  1. Create an API key: In Apollo, go to Settings → Integrations → API (https://app.apollo.io/#/settings/integrations/api) and click Create new key. Select the endpoints the key may access, or toggle ‘Set as master key’ for full access (some endpoints, like listing users, require a master key).
  2. Check your plan’s API access: API access and hourly/daily rate limits depend on your Apollo plan; free accounts have limited API quotas. Search endpoints are free to call, but enrichment and organization search consume Apollo credits.
  3. Set the environment variable: Add APOLLO_API_KEY to your .env.
  4. Verify access: Run the Search People tool with a simple keyword query.

​

  • Enrich Person, Enrich Organization, and Search Organizations consume Apollo credits
  • Email addresses in search results may be locked unless your plan/credits allow revealing them
