Type of the given procedure:

  • sellout.english


  • No need to specify enquiries period (there is no active.enquiries status), since it overlaps with active.tendering period.
  • For the process to start, owner should switch the procedure from pending.activation status to active.tendering.
  • During active.tendering period participants can ask questions, submit proposals, and upload documents.
  • Organizer is not allowed to set any changes within the procedure.
  • The given procurementMethodType is used during the first and second phase of the Small-Scale Privatization process.
  • For the procedure to become complete only 1 proposal is needed.
  • In case of a one proposal has been submitted, the auction itself will be ommitted.
  • Considering the number of proposals submitted, the Awarding process varies.


API accepts JSON or form-encoded content in requests. It returns JSON content in all of its responses, including errors. Only the UTF-8 character encoding is supported for both requests and responses.

All API POST and PUT requests expect a top-level object with a single element in it named data. Successful responses will mirror this format. The data element should itself be an object, containing the parameters for the request. In the case of creating a new auction, these are the fields we want to set on the auction itself.

If the request was successful, we will get a response code of 201 indicating the object was created. That response will have a data field at its top level, which will contain complete information on the new auction, including its ID.

If something went wrong during the request, we’ll get a different status code and the JSON returned will have an errors field at the top level containing a list of problems. We look at the first one and print out its message.
