We currently support two levels of signature:
- Simple signature (
level_1) - Advanced signature with a certificate (
level_2) - Simple signature without authentication (
level_0)
To sign a document with a simple signature, a signature certificate is not required from the participant.
To sign with an advanced signature however, the participant needs a certificate. If the participant does not own any, Universign will create one after a remote verification of the participant’s identity, directly within the transaction workflow.
The Level_0 signature allows the participant to sign his/her documents without authentication by OTP.
Note that the Level_0 signature depends on your workspace entitlements.
When configuring your transaction, you can define the minimum signature level required for a participant. Universign will always try to upgrade the signature level if it is possible. For example, if you request a level_1 signature for a participant who already owns a certificate, we will upgrade his signature for free. To set the minimum signature level for a participant, send a request to POST /v1/transactions/{transaction_id}/participants and pass the min_signature_level argument:
curl
https://api.universign.com/v1/transactions/tx_AWo949MOq0JE/participants \
-d email=john@company.com \
-d min_signature_level=level2
Note that the default value is level1.
Do not parameter authentication means if you request a level_0 signature.
