Electronic signature inside your WordPress forms
The Certyneo eSignature plugin connects Gravity Forms and WPForms to Certyneo, the European electronic signature platform. As soon as a visitor submits a connected form, an envelope goes out for signature from one of your Certyneo templates — no manual copy-pasting, no code.
The plugin is free and works with either Gravity Forms or WPForms (one is enough). Listing on the official WordPress.org directory is in progress — contact us for the install file in the meantime.
Why connect Certyneo to WordPress
A WordPress form already collects your visitors' agreement; Certyneo turns that agreement into a legally binding electronic signature, without switching tools or exporting a single row by hand.
Zero lines of code
Mapping form fields to template variables happens on the plugin's settings screen, in a few clicks.
Gravity Forms and WPForms
The two most widely used WordPress form builders are supported natively, with the same plugin.
No extra data stored
The plugin forwards the submission to the Certyneo API over HTTPS and only keeps a send log (success/failure, last 50 entries) for troubleshooting.
eIDAS signature, European hosting
Envelopes created this way follow the same compliance framework as the rest of Certyneo: eIDAS evidentiary value and hosting in Europe.
Works with the forms you already have
The plugin automatically detects which of the two builders is active and only loads the matching module.
Gravity Forms
Every form field maps to a variable in your Certyneo template, along with the signer's name and email, right from the form's settings screen.
WPForms
Same idea on WPForms: match fields to a Certyneo template from the form builder's Marketing tab, no code involved.
Set up the integration
Give it five minutes between activating the plugin and your first signature request.
- 1
Install the plugin
Upload "Certyneo eSignature" to wp-content/plugins, or through WordPress's Plugins screen, then activate it.
- 2
Generate your API key
In Certyneo, open Settings → REST API and create a key. Copy it: it is shown only once.
- 3
Paste the key into WordPress
Go to Settings → Certyneo, paste the key, then click "Test connection" to confirm it works.
- 4
Connect a form to a template
On the Gravity Forms or WPForms form of your choice, pick a Certyneo template and map each field to a variable and to the signer's name/email.
- 5
Submit a test entry
Send a test submission and check the plugin's log to confirm the envelope was created on the Certyneo side.
Security and compliance
The plugin only relays your submissions to the public Certyneo API, held to the same standard as the rest of the platform.
- End-to-end encrypted exchanges over HTTPS.
- No form data stored outside your WordPress database and Certyneo.
- Limited-scope API key, revocable at any time from your dashboard.
- Troubleshooting log capped at 50 entries, older ones purged automatically.
Frequently asked questions
Do I need both Gravity Forms AND WPForms?
No, either one is enough. The plugin only loads the matching module if the corresponding form builder is installed and active.
Does the plugin keep the form data?
No. Submitted values are sent directly to the Certyneo API over HTTPS to build the envelope; the plugin only keeps a short send log (success/failure) for troubleshooting, capped at 50 entries.
Which Certyneo plan do I need to use the plugin?
A live key (sk_live_…) requires a plan that includes API access (Standard and above). The Free and Personal plans come with a sandbox key (sk_test_…) to test the flow with no email sent to signers.
Does the WordPress plugin cost anything?
The plugin itself is free. Only your usual Certyneo subscription applies to API usage.
Is the plugin on the official WordPress.org directory?
The listing is being prepared. In the meantime, contact our team to get the install file.
