If you are looking for a Developer Partner to work with you on this, we do have The Marketplace available for you to peruse!
Should you wish to start coding yourself, we have a variety of resources available for those that would like to develop on the Infusionsoft API, most of which are accessible through the Infusionsoft Developer site.
First, you should review the acceptable use guidelines for integrations accessing the Infusionsoft API.
Next, set up a developer account to get credentials to use.
Then, use either an SDK or read the REST API or [XML-RPC API]
(https://developer.infusionsoft.com/docs/xml-rpc/) documentation to get started developing.
Finally, once you have a working integration, if you would like to make it available to other Infusionsoft customers you can submit your application to the Infusionsoft Marketplace.
Thank you for your interest in joining the Developer Partner community!
– The Infusionsoft API Development Team
