Intercom separates conversation data from contact data, which makes exporting a two-step process. cStar handles both.

Step 1: Export from Intercom

In Intercom, go to Settings > Data Management > Export:

  • Contacts CSV -- User and lead profiles (20MB limit per file)
  • Conversations -- Request via API or S3 export

Export contacts and conversations separately. You'll import them in two passes.

Step 2: Import Contacts

Intercom cStar
email Email
name Name
phone Phone
user_id External ID
created_at Created Date
custom_attributes.* Custom fields

Step 3: Import Conversations

Intercom cStar
source.subject Title
state Status
conversation_parts Message history
assignee Assigned Agent
tags Tags

Conversation Parts

Each part becomes a separate message, preserving author, timestamp, internal/public visibility, and content (HTML is sanitized during import).

Heads Up

  • CSV exports are limited to 20MB per file
  • Full conversation exports require API access
  • Leads import as customers without email addresses
  • Intercom's "snoozed" state maps to Pending in cStar

Upload everything at Settings > Team > Import.
