Firma.dev – E-Signature & Document Signing

Firma.dev brings e-signature to any WordPress site: send a contract, waiver, or agreement for signature from a page, a form submission, or your own custom code, and track its status without leaving wp-admin.

Unlike most e-signature plugins, Firma.dev for WordPress isn’t tied to one form builder or one workflow. It’s built around a single, universal way to trigger a signature request, so it works with whatever you’re already running.

How it works

1. Create your contract or document template in your Firma.dev dashboard (a free account takes a minute to set up).
2. In WordPress, pick that template under Firma → Send Setup, and map its fields to WordPress data (post fields, user fields, or fixed text) once.
3. Drop the [firma_send_signature] shortcode anywhere, or trigger it from any other plugin or custom code with a single WordPress action hook. Every send after that is automatic.
4. Track every sent document’s status (Sent, Viewed, Completed, Declined) under Firma → Documents.

Works with anything

Every trigger in this plugin, including the shortcode, funnels through one action hook:

do_action( 'firma_send_document', $mapping_id, $context );

Any other plugin or custom theme code can fire this to send a document for signature. Firma.dev isn’t limited to the integrations we’ve built, it works with your specific setup, out of the box.

Why Firma.dev

• Pay-as-you-go pricing (roughly €0.049 / ~5¢ per envelope), no monthly minimums, no per-seat fees. Send one document a year or ten thousand, you only pay for what you use.
• Legally valid e-signatures in 55+ countries.
• Built for developers and agencies as much as everyday site owners.

Firma.dev is a hosted service. A Firma.dev account is free to create and includes a no-cost test API key, so you can wire everything up and send a real test document before you commit to anything. Once you recieve your live key, you’re ready to send for real.

External services

This plugin connects to the Firma.dev API (https://api.firma.dev) to send documents for e-signature and track their status. A Firma.dev account and API key are required for the plugin to function. This is a core, required part of what the plugin does, not an optional add-on.

What is sent, and when:

• When a document is sent (via the shortcode or the firma_send_document action), the plugin sends the signer’s name and email address, plus any WordPress data you’ve chosen to map into template fields, to Firma.dev’s API to create and deliver the signing request.
• Every API request includes your Firma.dev API key for authentication.
• Firma.dev sends status updates (viewed, signed, declined, etc.) back to this site via a webhook you configure, so the plugin does not need to repeatedly poll Firma.dev for status.
