When navigating to Admin -> Company settings -> API Access there are no web service credentials (web service user name, shared secret).
How to retrieve those details?
You can view the actual API credentials for a user by going into the legacy user management area in Adobe Analytics. From the list of users, select a user. The username and shared secret are displayed on the resulting page.
For admins there are two ways to get the API Credentials for Users:
1. Login to Reports & Analytics
2. Click the "My Account" icon
(a) at the top-right corner of the page and then click Edit Profile
(b) as shown in the below screenshot:
3. Check for the API credentials under the section "Web Service".
4. If the section "Web Service" doesn't exist, reach out to any of the admins in your organization for access to "Web Service Access"
