Add secure eSignatures to your app with ease

An eSignature API, also known as an Electronic Signature API, is a software solution that enables developers to integrate electronic signature capabilities into their applications and websites. This allows users to electronically sign and send documents for signatures on a single app, thus eliminating the need for physical signatures.

The eSign APIs come equipped with functionalities such as document creation, authentication, tracking, and compliance, resulting in enhanced efficiency in document workflows and reduced paper usage, particularly beneficial for businesses.

Electronic Signature APIs enable developers to seamlessly incorporate electronic signature capabilities into their applications.

Users can either upload existing documents or create new ones, designate signing locations, authenticate their identity, and trigger the signing process.

The API then creates a distinct digital signature, securely attaches it to the document, and encrypts the file for enhanced security. Users receive notifications upon successful signing, and certain eSign API solutions provide options for document storage and the creation of audit trails as well.

These APIs ensure compliance with legal standards, guaranteeing the validity of electronic signatures.

Using an eSignature API, or Electronic Signature API, provides many advantages. It enhances efficiency by simplifying the signing process, enabling quick document turnaround.

Additionally, it offers accessibility for remote signing on various devices, reducing the reliance on physical paper documents, and contributing to cost savings and environmental sustainability.

The eSign API ensures robust security through encryption, authentication, and audit trails, making electronic signatures legally binding and compliant with regulations in many jurisdictions.

It seamlessly integrates with existing systems, aids in document management, and scales to suit businesses of all sizes, fostering collaborative signing among multiple parties.

Signeasy offers easy-to-integrate eSignature APIs with well-defined documentation for developers to quickly build, test, and go-live.

3. Implement authentication to secure access and design the user interface for document preparation and signing.
4. Integrate API endpoints to enable actions like document creation, signing, and management through HTTP requests.
5. Develop error-handling mechanisms and conduct extensive testing to ensure proper functionality.
6. Adhere to legal and security standards, offer user training if necessary, and deploy your application once testing is successful.
7. Continuously monitor, maintain, and optimize your integration as your application evolves.

At Signeasy, an envelope is a wrapper for documents that you send to a recipient to sign. An envelope can have one document or many documents, and one signer or many signers. Envelopes have statuses (i.e. sent, completed, voided) and also contain information about the sender and timestamps that indicate the progress of the delivery procedure.

Envelopes help you better manage the documents that are usually sent together and need to be signed together to complete a deal, an onboarding process, contract, etc.

Regardless of how many documents, fields, and signers a given envelope contains, it still counts as only one.
