Get an existing person. Either reference or externalIdentifier must have a value. If both are given, both are used for retrieving the person.
Get a Person
Retrieves the full record of a single existing person relation.
A developer calls this endpoint to look up an individual (as opposed to an organisation) that is already registered in Bloxs, typically before displaying their details, updating their information, or linking related records such as bank accounts or contact assignments.
A person represents a private individual relation type and can carry personal identification, date of birth, job title, and communication preferences in addition to standard address and contact data.

externalIdentifier | string | Required (at least one of reference or externalIdentifier must be given) | The external API identifier of the person, used when the integrating system tracks its own identifier for the record. |
