1. As an admin, enable web services and create an external service with an arbitrary shortname, e.g. externalservice . 2. Create a user testuser with the password Testpass1! that is able to access that service (either by allowing all users to use the service, or by restricting the external service to that particular user). 3. Grant the moodle/webservice:createtoken privilege to that user, e.g. by allowing it for the Authenticated user role. 4. In the name of the user, create a token by visiting the URL $CFG->wwwroot/login/token.php?service=externalservice&username=testuser&password=Testpass1! and write down the resulting token. 5. As an administrator, navigate to Site administration -> Plugins -> Web services -> Manage tokens. 6. Verify that the token from #4 shows up, with first and last name of testuser in the "User" column and the username testuser in the "Creator" column. 7. Still as an administrator, click "Add". 8. Select testuser for "User" and externalservice for "Service" and click "Save changes" 9. Verify that another token shows up, again with first and last name of testuser in the "User" column, but your administrator's username in the "Creator" column.
