# POA Sign Inline API

**POA Sign** enables automated, system-initiated signing on behalf of a user using a Power of Attorney (PoA) credential. Ideal for use cases where the end user has authorized the system to execute a signature without direct interaction.

This is especially useful in high-volume or backend workflows where user intervention is not required — such as auto-approvals, internal transactions, or signing archived documents.

**Key Features**

* **API-based delegated signing**: Sign on behalf of users without manual involvement.
* **Secure CVV-based flow**: Requires one-time CVV with time-bound validity (expires in 1 hour).
* **Flexible PDF placement**: Define the exact coordinates of signature appearance.
* **Regulatory compliance**: Adhere to Komdigi PSrE certified digital signature
