A2A INTEGRATION · CUSTOM TOOL

Use GitDealFlow A2A with Zapier

Visual automation across 7,000+ apps. Non-engineers who want VC signals piped into their existing stack (Notion, Airtable, Gmail, Slack).

Crunchbase API: $20K/yr. GitDealFlow A2A: free, no signup.

Zapier's Webhooks app POSTs JSON-RPC to our A2A endpoint with no code. Schedule trigger → Webhooks POST → Formatter (parse JSON) → Slack/Notion/Gmail. The path is uglier than n8n but Zapier reaches a much bigger surface of downstream tools — Notion databases, Google Sheets, HubSpot CRM.

Gotchas

Zapier's free plan caps Webhook calls and adds 15-min trigger delay — fine for digest use cases, painful for real-time. Upgrade to Starter ($30/mo) if you need <5min latency.
Zapier truncates large JSON responses in its UI preview; the full payload is still passed downstream — trust the field paths, not what the visual builder shows.
