Client credential flow
Client credential flow is the most frequently used authentication method. It requires ClientID, ClientSecret and UserID of the signer. DigiCert® provides you with a datasheet with ClientID and ClientSecret values. UserID is available at the end of the URL after the signer user creates their DigiCert ONE account.
Note
You are required to get an access token before the signing process in this flow. The access token is valid for one hour but can be extended by DigiCert® up to 24 hours.
