What is an eSignature API?
An eSignature API (Application Programming Interface) is a service that allows developers to embed digital signing functionalities directly into their own existing applications, websites, or business systems. Instead of requiring a user to leave your app to sign a document on a third-party platform, the API allows the entire signing process to happen seamlessly within your own user workflow.
How does an eSignature API work?
The process generally follows these steps:
- Request: Your application makes an “API call” to the eSignature provider (like Mekari Sign), sending the document (e.g., a PDF) and the signer’s information.
- Process: The API provider receives the request, wraps the document in a secure signing interface, and manages the identity verification (like sending an OTP) for the signer.
- Sign: The user signs the document within your application’s interface.
- Respond: The API provider cryptographically seals the document, generates a legal audit trail, and sends the final, signed document back to your application.
Why should my business use an eSignature API?
Integrating an eSignature API offers numerous benefits, including:
- Streamlined Workflows: Automate the entire document signing process, reducing manual effort and turnaround time.
- Enhanced User Experience: Allow users to sign documents directly within your platform or application for a smoother, branded experience.
- Increased Efficiency: Speed up document completion, leading to faster deal closures, quicker onboarding, and improved operational efficiency.
- Improved Security and Compliance: Leverage advanced security features like encryption and audit trails to ensure the legality and integrity of your signed documents.
- Cost Savings: Reduce expenses associated with paper, printing, postage, and manual document handling.
- Scalability: Easily scale your document signing processes as your business grows.
What are the key features of the Mekari Sign's eSignature API?
eSignature API from Mekari Sign offers a robust set of features, including:
- Embedded Signing: Seamlessly integrate the signing process into your existing applications or website.
- Auto Sign API: Automate signature placements for high-volume scenarios.
- Document Status API: Get real-time updates on the status of your documents (e.g., sent, viewed, signed).
- Upload, Send, Delete Document API: Manage the entire document lifecycle programmatically.
- Customizable Workflows: Tailor the signing process to fit your specific business needs.
- eMeterai (Electronic Stamp Duty) Integration: Easily add legally recognized electronic stamp duty to your documents.
- Secure Authentication: Robust mechanisms to verify user and application identity.
- Comprehensive API Documentation: Detailed guides and resources for developers.
- Sandbox Environment: A testing environment to develop and trial your integrations.
- Support for Various Programming Languages: Flexibility for developers.
Is an eSignature API legally binding?
Yes, but this depends entirely on the provider. The API is just the delivery tool. The legality comes from the signature itself. A signature created via an API is fully legally binding (equivalent to a wet-ink signature under laws like the ESIGN Act, eIDAS, or Indonesia’s UU ITE) only if the provider is a Certified Authority (CA) or, in Indonesia, a PSrE (Penyelenggara Sertifikasi Elektronik) recognized by Kominfo. This certification ensures every signature includes:
- Identity Verification: Proof of who the signer is (e.g., via e-KYC).
- Document Integrity: Proof the document was not tampered with.
- A Non-Repudiable Audit Trail: A secure log of the entire signing event.
Simple, non-certified eSignature APIs have very weak legal standing and are easily disputed.
Is there a free eSignature API?
Most legitimate eSignature API providers offer a free “sandbox” environment. This sandbox is a testing ground that allows your developers to build and test the integration with your application using test documents and fake signatures at no cost.
To send real, legally-binding documents (i.e., in a “production” environment), providers charge for the service. Pricing is typically based on a monthly subscription that includes a certain number of API calls or on a per-signature/per-envelope basis.
Does the eSignature API support e-Meterai?
This is a critical feature for any business operating in Indonesia. Most global eSignature APIs (like DocuSign or Adobe Sign) do not have this integration. A specialized API, like the one from Mekari Sign, is built for local compliance. Our eSignature API is fully integrated with PERURI (the official government mint), allowing you to automate both the application of a Certified Digital Signature and official e-Meterai in a single, seamless API workflow, ensuring your documents are 100% legally valid and tax-compliant in Indonesia.
What level of customization does the Mekari Sign eSignature API offer?
Mekari Sign API allows for significant customization to ensure a branded experience. You can customize email templates (logo, subject, message) for signature requests, creating a consistent look and feel that aligns with your company’s branding. The API is also designed to be flexible to suit various workflow requirements.
What are the typical use cases for the Mekari Sign eSignature API?
Our eSignature API is versatile and can be used across various industries and departments for numerous purposes, such as:
- Sales: Accelerate contract signing and proposal approvals.
- HR: Streamline employee onboarding, offer letters, and internal policy sign-offs.
- Legal: Execute legal agreements, NDAs, and other legally binding documents.
- Operations: Approve internal requests, work orders, and other operational documents.
- Finance: Sign off on invoices, purchase orders, and financial reports.
- Customer Onboarding: Simplify account opening and service agreements.
Can I integrate eMeterai (electronic stamp duty) using the Mekari Sign API?
Absolutely. Mekari Sign API offers seamless integration for eMeterai, allowing you to affix legally valid electronic stamp duty directly to your documents through your system. This speeds up the process and ensures compliance.
