Notes and Best Practices

  • Only include the fields you want to update in the request body
  • Be careful when updating the additional_data array, as it will replace the entire array rather than merge with existing values
  • If you’re updating a phone number, ensure it doesn’t conflict with another contact’s phone number
  • Consider implementing validation checks before submitting updates
  • Keep track of contact update history in your application if needed for compliance or audit purposes
