This API endpoint updates a specific client.
This PATCH request will only update the fields you specify (including custom fields), leaving the rest as they were.
Please note that for multi-select (tag) custom fields, all custom field options (tag values) must be included, the PATCH request will not preserve existing custom field options (tags).
Notes:
See notes on Create a Client for how to format customFields.
Coming soon: Support for multiple companies
It is not currently possible to add companies to a client via this endpoint.
Currently, passing a companyIds array to add multiple companies to a client via this endpoint is not supported, but will not return an error.
companyId is supported, but will only replace the single existing company for the client, this is also noted on the request body below.
We're working on adding this functionality soon!
