Apollo.io combines a B2B contact database with outreach sequencing. Connecting it to OpenClaw means your sales team can search for prospects, check sequence performance, and look up contact data directly from Slack.
How OpenClaw Integrations Work
OpenClaw is a self-hosted AI assistant that runs on your own server — typically an EC2 instance — and connects to Slack. It uses Claude under the hood to process requests. Out of the box, OpenClaw doesn't ship with pre-built connections to third-party tools. Instead, integrations are built using the skills system: markdown files in ~/.openclaw/skills/ that give Claude instructions for a particular domain, combined with HTTP tool calls to any API you expose to it.
In practice, adding a real integration means: getting API credentials from the third-party service, building or configuring a small proxy/endpoint that OpenClaw can call, and writing a skill file that tells Claude how to use it. For some tools this is an afternoon of work. For others — like Apollo.io — it's considerably more involved.
Connecting OpenClaw with Apollo.io: Step by Step
Step 1: Get Your Apollo API Key
Log into Apollo and go to Settings → Integrations → API. Copy your API key. Apollo's REST API base URL is https://api.apollo.io/v1/. Requests are authenticated with the key in the header X-Api-Key or as a query parameter.
Step 2: Use the Search and Sequences Endpoints
Key endpoints: /people/search (search contacts by title, company, location), /organizations/search (company search), /emailer_campaigns (list sequences and their stats), /contacts/{id} (contact detail and activity). The people search endpoint is the most useful for day-to-day prospect queries.
Step 3: Build the Proxy and Skill File
Wrap the search and sequence endpoints in your proxy. Write ~/.openclaw/skills/apollo.md documenting how to do a prospect search (what filters are available), how to look up a contact by email, and what sequence stats are accessible.
Challenges and Caveats
Credit Consumption
Apollo charges credits for contact data exports and enrichment. Queries via the API that return contact details may consume credits depending on your plan. Understand your credit allocation before building queries that could trigger large exports.
Data Coverage Varies by Region
Apollo's database coverage is strong for US/UK markets and thinner for some other regions and industries. Queries for contacts in niche markets may return limited results.
