target 17.0 ?

[sjai-odoo]

Hello @qle-odoo ,

Up to version 17.1, we had the option to directly select the terminal. However, starting from version 17.2 and subsequent versions, we now offer the choice between integrating with a terminal or using a QR code.

v-17.1

v-17.2 and subsequent versions

Therefore, we have included both options in the documentation to ensure that customers are not misled.
So we have created this in master after discussion with @mog-odoo

What's your call ?

Thank you.

@qle-odoo
Branch retargeted to 17.0
Can you please check again
Thank you

@LoredanaLrpz can you review this please

I've made the changes and approved, but it still has to be changed in saas-17.2 --> you do not need to activate the razorpay module anymore; we'll have to replace line 34 with Activate Razorpay in the PoS application settings (with ref).

Also, when creating a PM, we have the Integration field now, (saas-17.2+)
