How to use the online signature API
Using the online signature API involves a few straightforward steps. First, developers need to integrate the API into their existing systems or applications. This typically requires obtaining API keys and setting up authentication methods. Once integrated, users can initiate the signing process by sending documents to recipients for their electronic signatures.
To send a document for signature, users can specify the signers, set signing order if necessary, and customize the signing experience. The API allows for real-time tracking of document status, ensuring that users are informed when documents are viewed and signed. After all parties have signed, the completed document can be securely stored or shared as needed.

To ensure legal compliance when using the online signature API, organizations should maintain clear records of consent from signers, provide a secure method for signing, and ensure the integrity of the signed documents. Understanding these legal frameworks is essential for businesses to confidently adopt electronic signatures in their operations.
Security & Compliance Guidelines

This includes using encryption for data transmission and storage, as well as ensuring that access to signed documents is restricted to authorized personnel only.
Additionally, compliance with industry standards such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA) may be necessary, depending on the nature of the documents being signed.
