Error when connecting to Delpha

What to do when the connection to Delpha back-end is failing.

Symptoms

You try to connect your org to Delpha. After clicking the Connect button you are taken to a Delpha branded page that loops endlessly. You switch back on the Delpha Setup app page and you got a red toaster on top of the page with this error message: Error during connection. Connection could not be established with Delpha API.

That error tends to happen after an uninstall / reinstall process of the Delpha package.

What To Do

Case 1: You have uninstalled Delpha and you are reinstalling it

... that may have reset some External Credentials. Let's check.

1 - Get some data

In Salesforce Setup:

• Go To Salesforce Setup and search for: Named Credentials > External Credentials > Delpha_AWS > Principals

• if the Principals appear as Not Configured, get a screenshot.

2 - Drop the screenshot to Delpha, by chat, slack or email ([e-mail])

• Delpha support team will come back to you asap to properly update the Named Credential Delpha_AWS.

Case 2: You are setting up the connection with Delpha back-end

... that may be related to the Salesforce restriction on uninstalled Connected Apps (Sept 2025)

Starting in early September 2025, Salesforce blocks end users from authorizing or using uninstalled Connected Apps. Only apps that are explicitly installed (or users with special permissions) will work. (Salesforce)

⇒ Follow these steps to install the Delpha connected apps.
