How to Find the Custom URL Scheme for Adobe Fill and Sign on iOS
Question details
An app developer is looking for the correct custom URL scheme to launch the Adobe Fill and Sign iOS app directly from another application.
- Product
- Adobe Fill and Sign
- Device & OS
- iOS
- Scenario
- Developing an iOS app that requires triggering a third-party application to open and hand off a PDF document for filling and signing.
- Observed behavior
- The developer wants to implement a specific URL scheme for Adobe Fill and Sign, similar to the documented scheme available for Adobe Acrobat Reader.
Verify whether your target iOS environment supports universal links or custom URL schemes, and have your development console ready for testing.
Consult Adobe Developer Documentation and Support
Adobe Fill and Sign currently lacks a publicly documented URL scheme. Reaching out to Adobe Support or utilizing alternative Adobe apps is the recommended path.
While deep linking is a common feature for improving app-to-app user experiences, not all applications expose their URL schemes publicly. Because Adobe Fill and Sign does not have an officially documented scheme for third-party file handoff, developers must either seek direct support or implement alternative strategies.
Navigate to the official Adobe Developer Console to check for any newly released documentation regarding the Fill and Sign app URI scheme.
Open a direct support ticket with Adobe Developer Support to request official confirmation on whether app launching and file handoff are supported for Fill and Sign.
If Fill and Sign remains unsupported, utilize the known Adobe Acrobat Reader scheme ('com.adobe.adobe-reader://') as a fallback, since the Reader app also provides comprehensive form filling and signature capabilities.
Seamlessly Manage and Fill PDFs with WPS Office
Integrating third-party applications via undocumented URL schemes can be highly unstable for developers. WPS Office provides an incredibly powerful, free, and lightweight alternative for viewing, editing, filling, and signing PDF documents across all major platforms.
- 1. Download the App: Install WPS Office Free from the iOS App Store.
- 2. Open Your PDF: Tap on your PDF file and choose WPS Office to view the document instantly.
- 3. Fill and Sign: Access the built-in PDF tools to effortlessly fill out forms and add your digital signature.
Frequently Asked Questions
What is a custom URL scheme in iOS?
A custom URL scheme is a protocol created by app developers that allows their app to communicate with other apps. By triggering a specific URL format, another application can launch the target app and pass specific instructions or files directly.
Does Adobe Acrobat Reader have a known iOS URL scheme?
Yes, developers frequently use the 'com.adobe.adobe-reader://' URL scheme to open Adobe Acrobat Reader directly from other iOS applications to view and interact with PDF files.
Can I use WPS Office to fill and sign PDF forms on iOS?
Absolutely. WPS Office features a robust mobile PDF editor that allows users to easily view PDFs, fill out interactive forms, and securely append digital signatures directly from an iPhone or iPad.
How do I hand off a PDF file to another iOS app without a URL scheme?
If an app does not provide a custom URL scheme, developers can integrate the native iOS Share Sheet (UIActivityViewController). This native feature prompts the user with a menu to manually select which app they want to use to open the target PDF.
