Hi,
HikaMarket paypal adaptive plugin is compatible with Paypal adaptive when Paypal accept the right configuration.
We have a lot of users who have a good working paypal adaptive in their website ; I really don't know why they refused you to change the primary/secondary configuration. Because they are a lot of users with that exact config.
Now, I can modify the paypal adaptive plugin to support the non-sense configuration that paypal forced you to have.
I don't want to because I think it's stupid, but I can. It's not a problem of code, it's a problem of logic and good sens.
(nothing against you but I'm starting to be sick about some reactions of paypal support ; they made a documentation and they don't follow their own recommendations)
I know, I am sure that adding the option to put the store as secondary receiver will introduce a lot of error and a lot of support for something which does not feet to common configuration.
I will more recommend the "parallel" payment instead of the "chained" one.
In addition I wondered if there was a paypal option to pay vendors automatically & directly without using adaptive?
How do you want to pay your vendors automatically ?
The advantage of paypal adaptive is that, if an order is cancelled, everybody give back the money. If you use an automatic system to pay your vendors, you can have serious problem if the order is cancel or if you have a refund.
The best is to pay your vendors after a certain time ; keep some delay in order to be sure that you won't have any trouble afterwards (generally more 30 days is good).
After that, HikaMarket could create the vendor payment but doing an automatic payment transfer is risquy (and they are very few payment methods which could allow it).
I will work on the paypal adaptive plugin in order to see how implement the "store as secondary" feature without loosing future HikaMarket users in a really bad direction.
I noted your email address into the issue I created, so I will be able to send you the plugin once done.
Regards,
