Visma Sign is a online secure document signing service.

Organization API documentation is found at: https://sign.visma.net/api/docs/v1/

Partner API documentation is found at: https://sign.visma.net/api/docs/v1/

Library is meant to be production ready implementation for anyone using .NET platform and having integration with Visma Sign. Main point is that integration can be started right away without needing to spend time writing code to use Visma Sign's API.

It is enough to set your API credentials and environment endpoint that you are using. After this you can create your API requests.

var documentInformation = new DocumentDto("Example");

var documentLocation = await signClient.SendRequest<LocationDto>(new CreateDocument(documentInformation));

var attachment = await new HttpClient().GetByteArrayAsync("https://sign.visma.net/empty.pdf");

await signClient.SendRequest<IdentifierDto>(new AddFileToDocument(documentLocation, "empty.pdf", attachment));

var invitations = new AddInvitationsToDocument(documentLocation, new List<InvitationDto>() { new InvitationDto("test@visma.com", null, SignatureType.Strong, "John Visma", Language.Finnish), });

var createdInvitations = await signClient.SendRequest<List<InvitationCreatedDto>>(invitations);

Library requires implementing following interfaces:

1. ICredentials which defines credentials that are being used in API calls (contains InMemoryCredentials implementation to get you started).
2. IEndpoint which defines endpoint that will be used in API calls (contains InMemoryEndpoint implementation to get you started)
3. For partner credentials: IScopes which defines what scopes will be used when obtaining access token
4. For partner credentials: ICurrentOrganization. This interface defined what organization will be used in API calls (contains `InMemoryCurrentOrganization implementation to get you started).

API calls are made using ISignClient interface which is implemented by SignClient. Examples project has examples of constructing this class.

There are two different implementations of IApiRequest interface which will handle differences between organization/partner usage:

1. For organization: OrganizationApiRequest
2. For partner: PartnerApiRequest

Project contains examples how client library can be used. Examples are found in Visma.Sign.Api.Client.Examples project. It will also contain implementations for ICredentials, IEndpoint, IScopes and ICurrentOrganization for testing purposes.

If library is not currently implementing resource that you would like to use, it is possible to define this new resource without modifying source code.

For new resources to be used, create new class that inherits from ResourceBase and defined resource information. CreateDocument class can be used as an example.

API responses will be serialized to classes. If there is need to remove / add fields to be serialized, then new dto class can be defined and used in ISignClient.SendRequest calls.
