How to create Apollo auth credentials and configure it in Composio

2 min read

This guide walks you through creating an Apollo API key and configuring it in Composio.

Overview

  • Authentication type: API Key

  • OAuth required: No

  • Scopes: Not supported

  • Access control: Apollo plan + user role

Apollo uses API key–based authentication. Permissions are enforced internally by Apollo and cannot be modified by Composio.

Step 1: Generate an API Key in Apollo

  1. Log in to your Apollo account.

  1. Click on Create a new Key

  2. Give the key a name.

Apollo API Reference & Available Endpoints

In the same API section, Apollo displays a list of available REST endpoints that your API key can access.

Enable Master key to access all endpoints.

Commonly used endpoints include:

These endpoints allow you to:

  • Search and filter contacts

  • Search people and organizations

  • Retrieve account and user data

  • Power lead enrichment and prospecting workflows

The visibility of these endpoints confirms that your API key is active and ready to use.

Important: Save the API key securely. You may not be able to view it again.

Step 2: Understand Apollo Permissions (Important)

Apollo does not support OAuth scopes.

Access is determined by:

  • The Apollo subscription plan

  • The role of the user who created the API key

Typical accessible resources include:

  • People search

  • Company search

  • Contact enrichment

  • Basic sequence data (plan-dependent)

Composio forwards the API key exactly as provided. Apollo enforces all permission limits.

Step 3: Create Apollo Auth Config in Composio

  1. Go to Composio Dashboard:

  1. Click on the Create Auth Config button to get a list of all the toolkits available.

Step 4: How Authentication Works

When using Apollo with Composio:

  • The API key is stored securely

  • Composio injects the key into every request

  • Apollo validates and authorizes the request

  • No OAuth flow or redirects are involved

Step 5: Test Apollo Connection (Optional)

You can test the integration using Composio Playground.

Sample test prompt:

“Search for companies in the fintech industry”

If configured correctly, Apollo data will be returned successfully.

All Apollo API requests are sent to:

Final Step

Once configured:

  1. Copy the Auth Config ID (starts with ac_)

  1. Store it securely using a secret manager

  2. Use it in your application to authenticate Apollo via Composio
