Integrate e-signatures with your system

With our API, you can easily implement e-signatures in systems and existing workflows. Our API is accessible through web calls and uses JSON-formatted messages.

You can get e-signatures on web forms, existing documents or any data regardless of file type. If you have classified documents, you can choose to not send the document itself to the service – it is enough sending the document fingerprints calculated using to SHA2-512.

A case containing one or more documents can be signed by one or more parties. Information about the parties can either be filled from the API or collected in connection with the signature. You as the user of the API determine whether the included templates for communication with the parties are to be used, or if you want to handle the communication with the parties.

Depending on the level of assurance, how strong identification of the parties is needed in the specific case, you have the option to select one or several signature methods that parties can use to sign documents with. Currently, we have three different signature methods: eID, touch screen and SMS.

As a user of the API have control over the flow, what happens before signing and what will happen when the signature is complete.

If you have PDF documents with fillable fields, you can allow users to enter information in fields before the signing takes place. These fields can also be pre-populated with data before the parties are invited to sign.

There is of course also functionality to download and delete files that are stored with us.
