# Integrate Digital Signature to your platform
### Digital Signing for your users
**Enable seamless, legally binding document signing within your app using DirectSign API.**
If your platform requires users—customers, clients, applicants—to sign documents, DirectSign API helps you build that experience directly into your web or mobile application. This use case is ideal for digital platforms where signing is part of the core user journey. Whether you’re offering financial services, insurance, HR solutions, or property transactions, DirectSign API makes the experience smooth, secure, and compliant.
**Who it's for:**
* **Fintech platforms** letting users sign account opening or loan contracts
* **Insurtech apps** enabling policy or claim document signatures
* **HR software** that handles employment contracts and onboarding paperwork
* **Legal tech platforms** offering self-serve agreement signing
* **Property rental and sales apps** where tenants or buyers sign online
* And many more..
**Key Benefits:**
* Legally recognized signatures under Indonesia’s PSrE regulation
* Embedded experience with responsive UI for both web and mobile
* Built-in Authentication (Face Match / OTP) that meets OJK/Kominfo standards
* Easy status tracking via webhook and callback integration
* Reduces friction and drop-offs by keeping users in your app
**Why it matters:**\
Users expect everything to happen in-app. Sending them elsewhere to sign documents leads to confusion, lower conversion, and more support tickets. With DirectSign, you control the experience, speed up your flows, and meet compliance requirements—without compromising on usability.

### Digital Signing for your High-Frequency Signers
**Use POA Inline API to let key signers—like directors or executives—sign documents securely and at scale, even when they can’t be present for each action.**
In many regulated industries, certain documents must be signed by high-level company officers—such as directors, CFOs, or other authorized roles. However, these individuals are often unavailable for real-time signing due to volume, travel, or role constraints. That’s where **POA Inline API** comes in.
This API enables high-frequency signing on behalf of a legally authorized signer using a delegated credential, backed by a notarized power of attorney (Surat Kuasa). The signature remains legally binding under Indonesian regulations, and the authentication is handled by a delegated person—such as a legal or compliance officer—who acts within the scope of that power.
**Who it's for:**
* **Banks & financial institutions** needing director-level signatures for lending, compliance, or financial agreements
* **State-owned enterprises or large corporates** where directors must sign hundreds of recurring contracts
* **Procurement & finance teams** executing vendor or internal approvals in high volume
* **Insurance & telecom** operations that need authorized executives to sign thousands of policy or onboarding docs per week
* **HR teams** executing thousands of new employee signing
* And many more..
**Key Benefits:**
* Compliant with Indonesian PSrE regulation on certification policy
* Delegated signers authenticate and sign on behalf of executives via secure credentials
* Ideal for high-volume, repetitive signing workflows
* Removes bottlenecks from requiring real-time director presence
**Why it matters:**\
In regulated processes, skipping the right signature isn’t an option—but waiting for senior-level signers can delay business. POA Inline strikes the balance: signatures stay compliant and traceable, while operational teams can keep documents moving quickly. It’s a practical, secure way to scale executive-level signing.
