Update several contacts

with HubSpot
Works with AI assistants

Use HubSpot: its Hubspot Batch API lets you update several contacts in a single step (POST /crm/objects/2026-03/contacts/batch/update). HubSpot also has an MCP server, so an AI assistant like Claude or ChatGPT can do it for you. capabilities.work can help you get signed up and connected.

  • Can I change lifecycle stage or owner on a list of contacts by email?
  • Will a bulk contact update overwrite values that are already set?
Say it to your AI assistant
  • Update contacts with {contact_updates}.
  • Overwrite these contact properties: {contact_updates}.
For your developer
