We do have an API that allows business partners to automate the process of creating and managing Constant Contact accounts. Access to the SiteOwner API is a restricted access API provided to some Constant Contact Business Partners depending on the specific needs of the partner and the appropriateness of the API for those needs. If you would like to request the ability to use this API, please send an email along with your contact information over to our appconnect team, and they will get in touch with you regarding this.
