Summary of the article:
What’s Changing
Starting September 2, 2025, Salesforce is enforcing tighter security around the use of uninstalled connected apps. These are apps that users have authorized but were never formally installed into the org via the AppExchange or admin processes.
Why This Matters
This change is aimed at reducing security risks - including social engineering attacks - by preventing non-admin users from authorizing or accessing uninstalled connected apps. It also addresses vulnerabilities in the OAuth 2.0 device flow.
How this affects Payments2us Application
Payments2Us uses a connected app to support the “Authorise Payments2Us” step. In most cases, this step was already completed when you first installed the package, so your current setup is likely to continue to work without interruption.
That being said, with Salesforce’s upcoming security changes, there’s a small chance that you could run into issues and need to re-authorise the app (for example, if a connected user changes or the app needs to be reconnected), you may encounter issues after 2nd September unless the Payments2Us connected app has been installed. Hence, if you would like to be on the safe side, we recommend installing the Payments2Us connected app now. The installation steps are provided in the next section.
Installing the connected app:
- Aligns with Salesforce’s new security requirements
- Ensures future re-authorisations work smoothly
- Does not affect your existing configuration or data
The manual steps listed below will be required for any new Payments2Us installation after 2nd September.
Steps to Install Payments2Us Connected app:
Following steps can be performed to install Payments2Us Connected app.
- Go to Setup
- Search and find "Connected apps" > Connected Apps OAuth Usage
- Find Payments2us in list
- Click Install button
- Confirm the Installation on the next screen
We are also working to automate this setup in a future release but until then you manually install Payments2Us connected app.
