broker is current contract’s owner.
Note that response’s access section contains a transfer key which is used to change tender ownership.
After contract’s credentials obtaining broker has to provide its customer with transfer key.
Transfer creation
First of all, you must know ID of the contract that you want to transfer.
Broker that is going to become new contract owner should create a Transfer.
Request
POST /api/2.5/transfers HTTP/1.0
Authorization: Bearer broker3
Content-Type: application/json
Host: lb-api-sandbox.prozorro.gov.ua
{
"data": {}
}
Response
HTTP/1.0 201 Created
Content-Type: application/json
{
"data": {
"date": "2023-10-10T01:00:00+03:00",
"id": "0a30abb09f71439fa89d9a4c5bb50ea4"
},
"access": {
"token": "08f1d49be1284d93b4a95928f9028b33",
"transfer": "9763efce634449088e1683021b9db077"
}
}
Transfer object contains new access token and new transfer token for the object that will be transferred to new broker.
Changing contract’s owner
An ability to change contract’s ownership depends on contract’s status:
Allowed |
Not Allowed |
active |
pending terminated cancelled |
In order to change contract’s ownership new broker should send POST request to appropriate /contracts/id/ with data section containing id of Transfer and transfer token received from customer:
Request
POST /api/2.5/contracts/2b264b733b7546749561d03ffa5e7971/ownership HTTP/1.0
Authorization: Bearer broker3
Content-Type: application/json
Host: lb-api-sandbox.prozorro.gov.ua
{
"data": {
"id": "0a30abb09f71439fa89d9a4c5bb50ea4",
"transfer": "97d050219a734eb791b1fee00b50d095"
}
}
Response
HTTP/1.0 200 OK
Content-Type: application/json
{
"data": {
"owner": "broker3",
"id": "2b264b733b7546749561d03ffa5e7971"
}
}
Updated owner value indicates that ownership is successfully changed.
Note that new broker has to provide its customer with new transfer key (generated in Transfer object).
After Transfer is applied it stores contract path in usedFor property.
