eEvidSign signature API: how to automate electronic signature in your business processes

Real digitalization of business processes doesn’t just consist of replacing paper with PDFs. True efficiency comes when document workflows are automated, from document generation to signing, certification, and archiving.

This is where the eEvidSign signature API allows a qualitative leap: integrating electronic signature directly into your internal systems (CRM, ERP, intranet, onboarding platforms…), without friction and with all the traceability required by the eIDAS Regulation.

This article explains what the API can do, how it works, and why it has become an essential tool for companies seeking to automate and scale their signature processes.

Integrated signature: from platform to automatic workflow

eEvidSign allows signing documents from the web platform, but it’s through its API where —for companies with high document volume— electronic signature becomes a native piece of the digital workflow.

With the API, your systems can:

• Create signature requests in real time.
• Send documents to sign automatically.
• Position signatures and fields within the PDF.
• Receive notifications (webhooks) when the signature is completed.
• Automatically download signed documents and traceability.
• Query the status of each process without human intervention.

The API is the bridge that connects your business with a robust, secure, and legally valid signature system.

What the eEvidSign API allows you to automate

The API is designed to cover all common business signature scenarios, from simple contracts to complex workflows with reinforced validation. Among its capabilities stand out:

• Simple and advanced signatures
  You can create processes where the user signs with a click, or reinforce identity through an OTP code sent via certified SMS.

• Embedded forms and smart fields
  The API allows embedding fields within documents: text, checkbox, date, or fields defined in PDF forms. This enables cases such as:

  • Onboarding forms.
  • Informed consents.
  • Internal policy acceptance.
  • Data review before signing.

• Positioning by coordinates
  Each field can be located at specific positions in the PDF, allowing automation of dynamic documents.

• Multi-signer processes The API manages signature sequences (sequential signing) or parallel signing by multiple participants.

• Visual customization
  You can customize the signature experience with:

  • Corporate logo.
  • Color palette.
  • Interface language.

  All directly from the API call.

• Automatic and certified notifications
  If desired, the signature request can be sent via registered email from eEvidence itself, to ensure complete traceability. Or you can send the link through your own channel.

• Automatic delivery of signed document and audit trail
  Once the process is completed, the API returns:

  • The signed PDF.
  • The audit document with complete traceability (audit trail).

Common use cases

The API is especially effective in processes involving large document volumes or where signature is part of a larger process. Some examples:

• Automated commercial contracts. Automatic contract generation and immediate sending for signing.

• Digital customer onboarding. The customer reviews data, completes required fields, and signs from mobile or web.

• Human Resources. Employment contracts, annexes, renewals, or internal policies.

• Legal and financial sector. NDA agreements, loan contracts, authorizations, and regulatory documentation.

• Integration with CRM / ERP (Salesforce, Dynamics, HubSpot, SAP…) The API allows signature processes to occur within the native workflow.

The API as a digital transformation accelerator

Integrating electronic signature via API allows companies to move from manual and slow processes to automatic, auditable, and scalable workflows.

The most significant benefits are:

• Immediate operational savings.
• Reduction of errors and friction.
• Better user experience.
• Complete traceability from generation to signature.
• Scalability without needing to increase administrative staff.

The API converts signature into an invisible but essential piece within the company’s digital workflow.

Summary

The eEvidSign API is not just a technical tool: it’s the engine that allows transforming traditional document processes into completely automated, secure, and compliant digital workflows with European regulations.

For companies with scalability needs, multiple signers, advanced signature, or integration into complex systems, the API provides:

• Speed
• Security
• Automation
• Total control
• Probative evidence

The future of electronic signature lies in integration. And with eEvidSign, that future is already available.
