400 Bad Request.

[alex-75]

I had recently 3 or more 400 Bad Request errors in production.
All from customers that made successful payment before.
The payers are VERIFIED and payment method is "paypal" (usually the executed payment has payment mode "INSTANT_something", we do not accept cards at the moment)

What's happen?

How to get info about the error, have I to ask here every time ?

Thanks,

Alex

intent":"sale","payer":{"payment_method":"paypal", ...

Same user that made multiple payments in the past.
It fail to pay 100 EUR at 9:32 and it succedeed after 2 minutes. Obviously the application is not changed, so it is not an error for bad usage of the API.
