Once a publisher has signed up through your publisher interface, you'll receive an Onboarding Request.
In Order to approve the request, your publisher needs to verify through the Email, once he signed up.
The status of all incoming requests will be "not verified". Once the publisher verifies via email, the status will change to "verified" and display the "Approve" button.
Until the publisher doesn't verify, the "Approve" option will not be displayed.
Please ask your publisher to verify his email, before you can approve his request.
