WPsigner integration questions

Which WordPress plugins integrate with WPsigner?

WPsigner supports workflows with Gravity Forms, WPForms, Fluent Forms, Contact Form 7, Formidable Forms, Elementor, WooCommerce, MainWP, LearnDash, and Uncanny Automator. Availability and setup can vary by integration.

Can I connect an app that is not listed?

Yes. Use the REST API, signed webhooks, Uncanny Automator on the same WordPress site, or a cloud platform such as Zapier, Make, n8n, or Pabbly Connect.

Do integrations move my signed documents outside WordPress?

WPsigner remains self-hosted. Data only leaves your WordPress site when you explicitly configure an external service, such as cloud storage, messaging, CRM, identity verification, or automation.

Ready to Automate Your Signature Workflows?

Connect your existing tools to streamline document signing while keeping WPsigner self-hosted on WordPress.
