GET /registrations/{registration_id}/

Retrieve the details of a given registration. #### Permissions Only project contributors may retrieve the details of a registration that is embargoed, or has not yet been made public. Attempting to retrieve a private registration for which you are not a contributor will result in a **403 Forbidden** response. Authentication is not required to view the details of a public registration, as public registrations give read-only access to everyone. #### Registrations A registration on the OSF creates a frozen, time-stamped version of a project that cannot be edited or deleted. The *original project* can still be edited, while the registered version cannot. Registrations can be made public immediately or embargoed for up to 4 years. #### Withdrawals Registrations cannot be deleted, but they can be withdrawn. Withdrawing a registration removes the content of the registration but leaves behind basic metadata. A withdrawn registration will display a limited subset of information, namely, title, description, date_created, date_registered, date_withdrawn, registration, withdrawn, withdrawal_justification, and registration supplement. All other fields will be displayed as null. Additionally, the only relationship that remains accesible for a withdrawn registration is the contributors. All other relationships will return a **403 Forbidden** response. #### Returns Returns a JSON object with a `data` key containing the representation of the requested registration, if the request is successful. If the request is unsuccessful, an `errors` key containing information about the failure will be returned. Refer to the [list of error codes](#tag/Errors-and-Error-Codes) to understand why this request may have failed.
