How It Works 

 

Embed the Signing Flow:  
Company embeds the DirectSign iFrame (or SDK) directly into their app or web portal. 

 

Prepare Document & Initiate Signing:

When customer reaches signing stage, company’s system sends a request to DirectSign API with document, signer info, and config (auth method, signature field, etc).

 

Customer Authenticates & Signs:

User sees the document and signs it directly within the embedded flow, after going through secure authentication (Face Auth, OTP, etc.) — without leaving the app.
