Some Marketing Automation platforms offer a feature called "IP Whitelisting" where only certain IP addresses are allowed to login or interact with your account.
If configured to restrict APIs, please note that BrightTALK's Connectors will not be able to pass data to your system. We use Dynamic IP addresses and are unable to provide a list of the ranges that we use.
If you would still like to setup and use one of our Connectors, we recommend using the Form POST Connector instead of our standard API Connectors.
