How to add-in feature Open files on OneDrive with other application

Question

Hi Team
I am developing an electronic signature application. We now want to integrate it with OneDrive, and the concept is outlined below:

• Users utilize OneDrive to manage their documents. They should be able to right-click or select multiple files and then choose "Open with other application," which should support opening and navigating to my application. (You can refer to the SignNow application with Google Drive for an example.)

Based on my research, I need to follow these steps to achieve the idea:

1. Publish the application to https://appsource.microsoft.com/
2. Users can install the add-in on OneDrive to use it as a feature for opening files with other applications. I am not entirely sure about our research or which steps need to be taken to achieve the goal. It would be helpful if you could assist me in verifying the following:
   • The necessary steps to be taken
   • Whether it is possible to implement the add-in feature to open files with other applications
   Thank you so much

Hi @hoang hung

Since your question is related to OneDrive development, I can only provide limited help. Thank you for your understanding.

Please check whether File Handlers and File Picker are helpful to you.

• Using file handlers, developers can build apps that provide custom file experiences and light up new actions and activities inside the OneDrive experience.
• Using the file picker, you can connect your existing application in a matter of minutes, while enabling a whole new scenario for your users.

For Developer issues of OneDrive, I suggest you post thread on Microsoft Tech Community --- OneDrive Developer.
