Introduction to Apollo's APIs

The REST API provides a variety of opportunities for you to interact with Apollo’s platform functionality and data. Your organization’s API access is restricted by your current Apollo plan.

Use cases for Apollo's APIs include, but are not limited to:

• Build integrations: Integrate Apollo’s data and features in your own integrations. Use an OAuth 2.0 authorization flow to gain permission to query the endpoints you need on behalf of mutual users. The API offers the ability to retrieve data, create accounts, interact with sequences, and more!
• Enrich data: Use the Enrichment endpoints to perform data enrichment for both people and organizations. Enrich the data of an individual person or organization, or enrich data in bulk.
• Find people: Use the People Search endpoint to search Apollo’s data to find exact prospects based on demographics filters, including job titles, locations, and seniority.
