To implement multiple digital signatures with customizable positions and labels in a reactive OutSystems application, you can utilize the Reactive PDF Digital Signature (O11) Forge component. This component allows for digital signing of PDF documents within reactive web applications. (OutSystems)

🛠️ Step-by-Step Implementation Guide

1. Install the Forge Component

• Navigate to the Reactive PDF Digital Signature (O11) Forge page.

• Click on "Download" to add the component to your environment.(OutSystems)

2. Prepare Your PDF Document

• Ensure your PDF is accessible within your application, either by uploading it to the database or referencing it from a known path.

3. Integrate the Signature Functionality

• In your reactive web screen, add the necessary UI elements (e.g., buttons) to trigger the signing process.

• Use the SignPdf client action provided by the component. This action typically requires parameters such as:

  • InputPdf: The PDF document to be signed.

  • Certificate: The digital certificate used for signing.

  • SignaturePosition: Coordinates specifying where the signature should appear.

  • PageNumber: The page on which the signature should be placed.

  • Reason and Location: Textual information displayed with the signature.(OutSystems, OutSystems, OutSystems)

4. Add Multiple Signatures

• To include multiple signatures:

  • Invoke the SignPdf action multiple times, each with different SignaturePosition and PageNumber values.

  • Ensure that each signature is applied sequentially to the PDF.

5. Customize Signature Labels

• Modify the Reason and Location parameters to reflect the desired text. For example:

  • Reason: "Approved by Finance Department"

  • Location: "Mumbai Office"(OutSystems)

6. Handle the Signed PDF

• After signing, the component will return the signed PDF. You can then:

  • Display it within the application.

  • Provide a download link for users.

  • Store it in the database or a document management system.(YouTube, YouTube)

📌 Additional Considerations

• Ensure that the digital certificate used for signing is valid and properly configured within your application.

• Test the signing process thoroughly to confirm that signatures appear correctly on the specified pages and positions.

• For advanced features or issues, consider exploring other Forge components like Digital Signature for PDF Document (O11) which may offer additional functionalities.(OutSystems)

By following these steps, you can effectively implement multiple digital signatures with customizable positions and labels in your OutSystems reactive application.
