Either reference or externalIdentifier must have a value. If both are given, both are used for retrieving the commercial rent contract. **Description** Retrieve the information currently known in the Bloxs database about a certain finalised commercial rent contract. Either reference or externalIdentifier must have a value. Please note that if both identifiers are given, both must match; otherwise, an error message will be generated. It is recommended that the user utilizes only one identifier, with a preference for the reference. Commercial rent contracts concern the finalised contracts, which is essentially different from the 'ConceptCommercialRent' endpoints which relate to the concept contracts. Commercial rent contracts pertains to contracts concerning stores, offices, and commercial spaces (commercial real estate). Please note that it is currently not possible to finalise a contract through the Bloxs api's. If a concept rent contract is created using the [POST operation](/v1-api/apidocs/preview-insert-a-concept-commercial-rent-contract), it will first need to be finalised in the Bloxs application before it can be retrieved through this GET operation. **Use Case** Upon finalising the contract in the Bloxs application, the user wants to retrieve the most important details of the contract in a third party application. **Request****fields** The request contains the following fields: | Field | Description | | --- | --- | | reference | The reference of the contract as generated by Bloxs. | | externalIdentifier | The unique identifier of the contract within the system of the requesting party.
