Step-by-step setup for the most popular AI clients.
Setting up Apollo.io
From the connector definition itself: where to find the credentials, what they need to be allowed to do, and which API this adapter talks to.
This connector uses the Apollo.io API v1 (docs.apollo.io).
Setup:
- Sign in to Apollo.io → top-right avatar → Settings → Integrations → API → API Keys → Create New API Key.
- Name it ('AnythingMCP'). Copy the key.
- Set
APOLLO_API_KEY.
Authentication: header X-Api-Key: ${APOLLO_API_KEY}. (Note: Apollo also supports the api_key query parameter and the legacy Authorization header; this connector uses the header form.)
Search vs Enrich: Apollo's central feature is searching its 275M+ people database (/v1/mixed_people/search). match endpoints enrich a known person/company by email/domain. People search is the entry point for prospecting workflows.
Credits model: every enrich, mixed_people/search result, and reveal-email/phone call costs API credits. Read your plan's credit balance before bulk operations. Apollo returns 429 quota exceeded (NOT a normal 429) when credits run out.
Email reveal mechanics: searching returns 'unrevealed' contacts with email=null. To get the email, call apollo_people_enrich for that specific person — that consumes credits. Plan accordingly.
Sequences: Apollo's outreach engine. Pulling contacts via search → adding them to a sequence is the most common write flow. Cadences are configured in the UI; the API just adds/removes contacts.
Filters: people search accepts many filters — person_titles, person_locations, organization_num_employees_ranges, organization_industry_tag_ids, contact_email_status, etc. The adapter exposes the most common.
Pagination: 1-based page parameter, per_page max 100. pagination.total_pages tells you when to stop.
Rate limits: per plan — varies wildly. Enterprise has multi-thousand req/min, Starter much lower. On 429 honor Retry-After.
Out of scope here: lead-scoring config, sequence template editing, conversation intelligence, plays/dispositions, billing.
