Mel,
I'm so sorry we missed your question above! We do answer our forums, and try to do so at least on a daily basis, but we missed this one in the Pre-Sales questions area.
We haven't done any additional PayPlans integration over the last 6 months, and the post you linked to was from 4 years ago, just to call that out. Part of the reason we haven't done any development specifically related to PayPlans integration is because it hasn't been requested very much in the past. A few years ago, there was quite a bit of requests for deeper PayPlans integration, like in the topic you linked too. However, since that time, the developers of PayPlans put out a JFBConnect integration plugin/app which (from reading it) does what you're looking for:
www.readybytes.net/payplans/apps/pp-jfbc...l#/app/pp-jfbconnect
I haven't tested that app at all, but it's definitely where I'd start. We try not to add deep integration with every extension out there if we don't have too. It's much easier if those extension developers, who know their product, hook into our system.. which is what it sounds like ReadyBytes has done.
Please investigate and see if that helps. Also, FYI, through Monday, we're running our Black Friday promo of 25% off. If interested, add JFBConnect to your cart and add the promo code shown on the checkout page to get the discount!
I hope that helps and we'd love to see you back as a customer!
Thanks,
Alex
