What this workflow does

This AI workflow has 30 nodes and runs when an HTTP POST request hits its webhook URL (plus 2 other triggers). Along the way it connects Slack, Anthropic Chat Model, HubSpot and Gmail and 2 more. It also calls app.findymail.com, public.api.twain.ai and api.apollo.io over HTTP.

How it runs

Trigger: When an HTTP POST request hits its webhook URL (plus 2 other triggers).

1. Settings (Edit Fields (Set)): sets 3 fields: campaign_id, slack_channel, ae_email
2. BigQuery: New signups (Google BigQuery): uses Google BigQuery
3. Firestore: New customers (Google Cloud Firestore): query
4. Normalize Signup (Edit Fields (Set)): sets 10 fields: uid, email, displayName…
5. Dedupe New Signups (Remove Duplicates): removes duplicate items
6. Needs LinkedIn Lookup? (If): checks a condition and branches into true / false
7. LinkedIn Lookup — Findymail (HTTP Request): calls app.findymail.com (POST)
8. Resolved Contact (Merge): merges the data from its input branches
9. Apply Resolved LinkedIn (Code): runs custom JavaScript code
10. Has usable contact? (If): checks a condition and branches into true / false

…plus 14 more steps. See the full node list below.
