Summary

Update a contact list entry or contact book in MMIO. The node sends the supplied JSON as the request body and returns the API response as n8n output items.

Inputs

  • Category (required) — Choose Contact Lists or Contact Books. Although Contact Tags is also an option, the update handler does not implement tag updates.
  • Contact ID (required) — For Contact Lists, the ID of the contact to update.
  • Book ID (required) — For Contact Books, the ID of the contact book to update.
  • Contact JSON Data (required) — Valid JSON fields to send in the update request body. The example for a contact includes names, email, subscriber status, book IDs, and tags; the example for a book includes a name.

Output shape

One or more n8n items containing the API response.

The handler uses POST for updates. If the API response is an array, its elements are returned as separate items; otherwise, the response is returned as one item. Invalid JSON causes an error.

Examples

Example 1: Update contact

Select Contact Lists, enter a Contact ID, and provide JSON fields to update.

Example 2: Update contact book
