Create a FeedBlitz account, if you do not already have one. You do not need to upgrade the account.
Send an email to support@feedblitz.com that contains information about the planned integration and the email address for the account. We will review the request, enable the account for testing purposes, and send you further instructions.
Most requests will be granted within a business day. We may ask you a little more about your needs to help us to help you choose the appropriate API for your application.
