Create a client
Create a new client (the end customer of the partner) with identity, contact, and related-data fields. Scoped to the partner the API key belongs to. customProperties accepts the custom properties defined for your partner, keyed by property id; send null to clear one. Requires the client:write scope.
Authorizations
Send the API key in the x-api-key header.
Body
1"Sam"
1"Client"
Custom property values, keyed by property id. Ids and value types come from the properties defined for your partner, so this object cannot be described field by field here: an unknown id or a value that does not match the property type is rejected with 400. Only the ids you send are modified — omit a property to leave it untouched. To clear one, send null; a blank string and an empty array count as empty too, for every property type alike.
