Hi,
It seems the integration between Amaka and Stripe is not yet ready:
amaka.com/integrations/
You're talking about both Square and Stripe in your message so I'm not sure which one you want.
Regarding Stripe, the Stripe Connect payment plugin developed by Obsidev and available on our marketplace doesn't send the details of the order to Stripe. I'm not familiar with the Stripe APIs used by the plugin so I'm not even sure if that's possible with them.
Sending the details of the order for this plugin would require a big development, maybe the development of a completely new plugin to support other APIs (like Stripe Checkout).
Regarding Square, the Square payment plugin developed by Tsukidev and available on our marketplace does send the details of the order to Square. I checked the code of the plugin and I can see that even though it sends the details of the order, it doesn't include the tax amounts. That's something which could be added relatively easily by the developer of the plugin. If you need it, I would recommend contacting Tsukidev directly at
tsukidev.com/contact/
and check with them what's possible.
