Creating a Salesforce OAuth 2.0 Client ID
To use OAuth 2.0, Create a New Connected App in Salesforce. You can search for the App Manager from the Quick Find search box or navigate Platform Tools --> Apps --> App Manager. Open the App Manager and Click New Connected App. Additional information about these steps can be found here.
Complete the required Basic information for the New Connected App, Connected App Name, API Name, and Contact Email.
Continue to the API section of the New Connected App form. Check the Enable OAuth Settings checkbox. In the Callback URL field, enter the following address: https://app.onecloud.io/oauth/callback. The Perform Requests on your behalf at any time (refresh_token, offline_access) must be added to the list along with at least one other OAth scope of Selected OAuth Scopes. Additional scopes may be added as required to support the functional integration requirements. The remaining fields can be left with their default settings. Click the Save button and when prompted regarding the time to refresh, click Continue. Additional information about these steps can be found here.
After waiting the required time noted by Salesforce, return to OneCloud Connections and add a new Salesforce Connection.
