Summary

Updates an existing Sumit customer by sending customer details to the Sumit Accounting API. Provide the customer name and, in Additional Fields, the Sumit customer ID; optionally supply contact details, company number, and other customer fields.

Inputs

• Name (required) — Customer name sent as Name.
• Email — Optional customer email, sent as EmailAddress.
• Phone — Optional customer phone number.
• Company Number — Optional company registration number (HP/ID).
• Additional Fields — Optional city, address, zip code, external identifier, No VAT flag, customer ID, and folder. Set Customer ID to the Sumit ID of the customer to update; these fields are merged into the request details.
