# Accept e-signature

> Records the user's consent to conduct business electronically (E-Sign Act compliance).

**Authentication:** the presigned URL is the authentication mechanism for the end user;
this endpoint must be called by or on behalf of the user who will be bound by this consent.

**Legal effect:** by calling this endpoint with a valid presigned URL, the user consents to:
- Receive documents and disclosures electronically
- Use electronic signatures for legally binding agreements
- Conduct transactions electronically

This is typically the first agreement accepted during onboarding.
