## Set Values

`v1.custom_fields.set_values(CustomFieldSetValuesParams**kwargs)`

**post** `/v1/customFields/setValues`

Sets one or more custom fields on an instance of a Metronome entity. If a key/value pair passed in this request matches one already set on the entity, its value will be overwritten.

This endpoint is transactional and will update all key/value pairs or no key/value pairs. Partial updates are not supported. There is a 200 character limit on custom field values.
