Card Vaulting Network Errors when burst in placing orders

Hello,

I’m receiving a lot a Network Errors when tokenizing the credit card. Do you have any documentation / data about the limit ? I’m talking here about the [https://elb.deposit.shopifycs.com/sessions](https://elb.deposit.shopifycs.com/sessions`) endpoint.

We do live shopping and we can have a burst of orders for a short period of time.

PS : I have no issue with implementing the leaky bucket algorithm handling on the Storefront API. In fact I do not have issues with the rate limitation on the storefront api. but vaulting the card I just get Network Errors and really a lot of network errors even the orders are placed from different ips (obvisouly)

UNLESS you guys you have a workaround using stripe to do the vaulting (or spreedly)

Thanks for any help.
