| DID Connection Invitation | Generic. The service generates and provides a JSON invitation (DID document) with which the different stakeholders (e.g., users) can start the process of DID connection establishment. | VC |
| DID Connection Response | Generic. The service validates and checks the user's response to the generated DID connection invitation. As a result of this action, information on the DID connection establishment is provided. | VC |
| VP Validation | The service performs an initial screening and validation of the VP submitted by the user with regard to its schema structure, eIDAS identity matching and the validity of the digital signature. The result of this action is the information on the validity of the VP submitted for the procedure. | VC |
| VP Request | The service, dependant on procedural requirements, generates a request for evidence in the form of verifiable presentations (VPs). It requires evidences to be aligned with a specific VP format. | VC |
| VC Issuing | The service provides functionalities related to (re)issuing of requested evidence in the form of a VC. The VC is issued through an established DID connection and accepted VC. | VC |
