# Summary
Our SSI mandate service is a generic and holistic approach to provide and request mandates. Mandates are SSI credentials signed by the dependent that can be requested by either the dependent or authorized representative. These credentials can be used to prove to a verifier that the authorized representative is authorized to act for specific actions on behalf of the dependent. The mandate credentials are stored in the wallet of the authorized representative as opposed to a central database in current systems. The dependent can revoke this credential at any point in time if he/she no longer wants the authorized representative to act on their behalf by updating a revocation hash on the blockchain. The SSI mandate provides mandates completely peer to peer and isn’t limited to individuals only. A SSI wallet can also represent a device or institution, for example a company can use a SSI company wallet to authorize employees to access the building or use the company credit card up to a certain amount.
Overall, mandates can be used for 2 different purposes:
- To authorize someone to have acess to data of someone else.
- To authorize someone to act on behalf of someone else.
The SSI Mandate Service is already used in different cases:
- Cross Border Delegation (Customs): Authorizing a company to do the customs administration on behalf of an importer from the Netherlands
- Construction site access: Authorizing a subcontractor or self-employed to have access to a construction site to be able to work for a main contractor.
# SSI Mandate project
The current SSI Mandate Service is described in the [functional specification](https://gitlab.grnet.gr/essif-lab/infrastructure_3/visma-connect/deliverables/-/blob/master/functional_specification.md). The specification describes the flow of defining, creating, accepting and proving a mandate. Next to that, the architecture of the SSI Mandate Service describes the components and the relation with the SSI Platform and the different users. The [interface specification](https://gitlab.grnet.gr/essif-lab/infrastructure_3/visma-connect/deliverables/-/blob/master/interface_specification.md) describes how you can use the Mandate Service using an API.
