Integrating the e-Signature.eu API means eliminating manual friction, ensuring eIDAS compliance and keeping your clients within your own digital environment \u2014 no subscription, no infrastructure to deploy.<\/p><\/header><div class=\"content-section\"><p>For a CTO or IT manager, the question is no longer whether electronic signatures are useful \u2014 they are \u2014 but how to integrate them seamlessly into existing systems. CRM, ERP, client portal, onboarding platform: every break in the user journey between your tools and a third-party signing service represents a risk of abandonment, an additional delay and a degraded experience for your users.<\/p><p>An electronic signature API solves this problem at the source. It allows you to trigger, track and retrieve signatures directly from your applications, without ever forcing the user to leave your environment.<\/p><div class=\"info-box\"><h4>\u2705 What API integration changes in practice<\/h4><ul style=\"margin-bottom: 0;\"><li>Automatic triggering of signature requests from your existing workflows<\/li><li>Real-time tracking of each signature status via webhooks<\/li><li>Automatic retrieval of the signed document<\/li><li>Centralised visibility over all signatures in the e-Signature.eu dashboard<\/li><li>Choice of signature level (QES, AES, SES) suited to each regulatory context<\/li><\/ul><\/div><\/div><div class=\"content-section\"><h2>A multi-method API, eIDAS compliant<\/h2><p>The e-Signature.eu API exposes all the signature methods available on the platform, each corresponding to a level defined by the eIDAS regulation. A single endpoint is enough to cover all your use cases, from low-sensitivity internal documents to high-value legal contracts.<\/p><table><thead><tr><th>Method<\/th><th>eIDAS level<\/th><th>Coverage<\/th><th>Cost \/ signature<\/th><\/tr><\/thead><tbody><tr><td><strong>itsme\u00ae<\/strong><\/td><td>QES \u2014 Qualified<\/td><td>32 European countries<\/td><td>1 credit<\/td><\/tr><tr><td><strong>Evrotrust<\/strong><\/td><td>QES \u2014 Qualified<\/td><td>62 countries<\/td><td>1 credit<\/td><\/tr><tr><td><strong>Veriff<\/strong><\/td><td>AES \u2014 Advanced<\/td><td>198 countries<\/td><td>0.7 credit<\/td><\/tr><tr><td><strong>OTP Email<\/strong><\/td><td>SES \u2014 Simple<\/td><td>Worldwide<\/td><td>0.4 credit<\/td><\/tr><\/tbody><\/table><div class=\"callout-box\"><h4>\ud83d\udccc Regulatory reminder<\/h4><p style=\"margin-bottom: 0;\">Only a qualified electronic signature (QES) is legally equivalent to a handwritten signature under the eIDAS regulation. It is notably required by certain administrations such as the INPI in France. The API allows you to dynamically select the appropriate level according to the document type or regulatory requirement.<\/p><\/div><\/div><div class=\"content-section\"><h2>Two integration modes for your architecture<\/h2><p>The API offers two distinct operating modes, suited to different levels of integration and user journey requirements.<\/p><div class=\"mode-grid\"><div class=\"mode-card mode-card-classic\"><div class=\"mode-tag tag-classic\">Classic mode<\/div><h4>\ud83d\udce7 Invitations managed by e-Signature.eu<\/h4><p>You send the document and the signatories&#8217; details. The platform handles email invitations, automatic reminders and tracking.<\/p><ul style=\"margin-bottom: 0;\"><li>Quick and lightweight integration<\/li><li>Emails and reminders included<\/li><li>Ideal for asynchronous workflows<\/li><\/ul><\/div><div class=\"mode-card mode-card-embedded\"><div class=\"mode-tag tag-new\">Embedded mode \u2014 New<\/div><h4>\ud83d\udd17 Signing URL returned to your server<\/h4><p>The API returns the signing URLs directly to your server. Your clients sign immediately within your own site or application, with no break in the journey.<\/p><ul style=\"margin-bottom: 0;\"><li>100% experience within your environment<\/li><li>Real-time signing, without an intermediary email<\/li><li>Ideal for conversion funnels and onboarding<\/li><\/ul><\/div><\/div><div class=\"callout-box\"><h4>\ud83d\udca1 Concrete example<\/h4><p style=\"margin-bottom: 0;\">A financial institution integrates the API in embedded mode: as soon as a client finalises their account opening request, the QES signing URL is generated server-side and displayed directly in the interface. The client signs in seconds, without leaving the portal. The signed document is automatically archived via webhook.<\/p><\/div><\/div><div class=\"content-section\"><h2>Integration in 2 steps<\/h2><p>The e-Signature.eu API follows a standard RESTful architecture, accompanied by comprehensive documentation and a ready-to-use Postman collection.<\/p><div class=\"step-box\"><h4>Step 1 \u2014 Authentication &amp; submission<\/h4><p style=\"margin-bottom: 0;\">Secure API key, then transmission of the PDF with the signatories&#8217; details, the chosen signature method and the operating mode (email or server URL).<\/p><\/div><div class=\"step-box\"><h4>Step 2 \u2014 Signing &amp; retrieval<\/h4><p style=\"margin-bottom: 0;\">Email sent or URL returned to your server. The signature status and signed document (Base64) are automatically delivered by webhook as soon as the signature is completed.<\/p><\/div><\/div><div class=\"content-section\"><h2>Typical business use cases<\/h2><h3>\ud83c\udfe6 Banking, insurance &amp; fintech<\/h3><p>Client onboarding, SEPA mandates, credit agreements: the API lets you integrate qualified signing with identity verification (Evrotrust or Veriff) directly into the client journey, with no break between KYC and signature.<\/p><h3>\ud83c\udfe2 CRM &amp; contract management<\/h3><p>Connect the API to your CRM (Salesforce, HubSpot, Odoo\u2026) to automatically trigger a QES signature request as soon as a quote is approved. Sales teams no longer need to manually manage sending or tracking contracts.<\/p><h3>\ud83c\udfd7\ufe0f Real estate &amp; property management<\/h3><p>Leases, inventory reports, mandates and sale agreements: the API allows you to collect signatures from multiple parties with fine-grained control over signing order and full traceability at every step.<\/p><h3>\ud83c\udf0d Internationally active businesses<\/h3><p>With Evrotrust (62 countries) and Veriff (198 countries), a single API integration covers all your markets. No need to juggle multiple providers depending on the geography.<\/p><\/div><div class=\"content-section\"><h2>An economic model built for professional volumes<\/h2><p>The e-Signature.eu API is based on a pay-as-you-go model with no subscription and no volume commitment. A <strong>degressive pricing<\/strong> structure applies: the more you use, the lower the cost per signature.<\/p><p>For IT teams, this model eliminates the risk tied to annual commitments and allows for progressive scaling \u2014 you pay for exactly what you use.<\/p><div class=\"warning-box\"><h4>\ud83d\udca1 Good to know<\/h4><p style=\"margin-bottom: 0;\">1 credit = 1 signature, regardless of the number of documents in the request.
