API integration

To integrate Wild Apricot with GoTo Webinar software by Citrix through the use of APIs. I regularly hold webinars for our members and non-members, and non-members are asked to pay - so we use Wild Apricot to register them and take payment but we would like to avoid asking the participants to register twice, in two different systems. If we can get the programs to talk, they would only need to register once in Wild Apricot, and that would then talk to GoTo Webinar. GoTo Webinar has supplied this link for reference: [login to view URL] Can you please advise time to set up and cost per hour
