It's easy to set an offer to automatically approve any affiliates that apply to it.
You can enable this option by either editing an existing offer or creating a new offer.
To create an offer and enable this option go to Manage>Offers>Create New
On the General Offer Settings page, you'll want to click to expand the Advanced Options.
Second, you'll need to change the drop down under "Automatically approve affiliates who apply to this offer" to "Yes". Affiliates will be taken to the affiliate dashboard after signup and receive the welcome email right away.
When any affiliate registers for this offer they will be automatically approved.
Please note: The Post-Purchase widget automatically approves all affiliates on its own.
