The MOs that use Hubject CA should use the generateSignedContractData interface, where the contract data will be generated, sent to the CPS for signing and then stored in the CCP.
After receiving a PCID from the customer and generating an EMAID, the MO sends the contract information to the Hubject Mobility Operator CA to create the contract data. The contract information includes PCID, EMAID and contract begin and end dates.
