Delete source system apartment using source system information

The Delete /externalSourceSystemApartment operation is designed to permanently remove a source system apartment using its associated information. This process involves eliminating all references to the apartment, but once deleted, it cannot be restored. If the operation fails unexpectedly, some objects linked to the apartment may be remapped to a default apartment, even if the original apartment still exists. In such cases, these remapped objects will not revert to their previous state. The operation requires an Authorization Token for security and includes mandatory path parameters: sourceSystemId and sourceSystemKey. Possible responses include a 204 status for successful deletion, a 401 status for missing or invalid authentication credentials, and a 403 status indicating that the request is valid but cannot be executed, often due to dependencies on other objects. Detailed error descriptions are provided in the response for troubleshooting.
