How do embedded signatures work inside your app?

We’ve built a simple demo application with an integrated eSignature workflow, so you can observe each step, explore code examples, and evaluate the end-user experience.

Behind the scenes
Technology:
  • PHP 8.2
  • Docker
  • Laravel 10
  • Native JavaScript
  • airSlate SignNow API PHP SDK 2.2
  • HTML
  • Bootstrap CSS Framework
The application contains both backend and tiny frontend components. The frontend consists of a web form where you can enter the first and last names of your signer and a comment.

Behind the scenes
After the form is submitted, the backend uploads the PDF file to airSlate SignNow using your credentials provided with the .env configuration file. The backend also adds the first and last names and comment fields to the document. The backend then creates an embedded invite to sign your document and generates a link for the invite. This type of invite is called 'embedded' because you can integrate it into your website or mobile application.

The frontend receives the invite link and embeds the airSlate SignNow document editor into a website or app using an <iframe/> tag. Using this method, the signing session is built into the website. You can also customize the signing experience by using the branding feature. All backend operations are performed using the airSlate SignNow PHP SDK.
