Apollo Migration Deep Dive

Current State

!npm list 2>/dev/null | head -10

Overview

Migrate contact and company data into Apollo.io from other CRMs (Salesforce, HubSpot) or CSV sources. Uses Apollo's Contacts API for creating/updating contacts and Bulk Create Contacts endpoint for high-throughput imports (up to 100 contacts per call). Covers field mapping, assessment, batch processing, reconciliation, and rollback.

Prerequisites

• Apollo master API key (Contacts API requires master key)
• Node.js 18+
• Source CRM export in CSV or JSON format

Instructions

Step 1: Define Field Mappings

// src/migration/field-map.ts
interface FieldMapping {
  source: string;
  target: string;        // Apollo Contacts API field
  transform?: (v: any) => any;
  required: boolean;
}

// Salesforce -> Apollo
const salesforceMap: FieldMapping[] = [
  { source: 'FirstName', target: 'first_name', required: true },
  { source: 'LastName', target: 'last_name', required: true },
  { source: 'Email', target: 'email', required: true },
  { source: , : , :  },
  { : , : , :  },
  { : , : , :  },
  { : , : , : ,
    :  url?.() ? url :  },
  { : , : , :  },
];


 : [] = [
  { : , : , :  },
  { : , : , :  },
  { : , : , :  },
  { : , : , :  },
  { : , : , :  },
  { : , : , :  },
  { : , : , :  },
];

 (): <, > {
   : <, > = {};
   ( m  mappings) {
     value = record[m.];
     (m. && !value)   ();
     (value && m.) value = m.(value);
     (value) mapped[m.] = value;
  }
   mapped;
}
