Yes, but you still depend on the fact that client's browser will or will not do something.It's not really reliable, especially when we're talking about financing stuff.

Also, if you require of us to charge our clients using Shopify billing API, it would be nice to know if client didn't pay.Won't you agree ?

How can I know it has been confirmed by client ?Should I depend only on clients browser redirect ? It's not really reliable, isn't it ? 

We have SaaS app that integrates with shopify (along with other services). Client uses it for example on our mobile application.He needs to buy a billing plan on our application in ourder to use it.He has to have account on our side. If we won't know...

I cannot find any webhooks related to billing.I need to know when one-time application charge changes status.Is it possible to be notified by shopify when it happens, or should I monitor it myself, requesting charge status periodically ? 

Ok, I solved it, it's second time I faced this issue  Springs RestTemplate adds additional HTTP headers, that are not allowed by shopify: Accept, Content-Length, Content-Type

Howdy. I cannot get billing api to work.Every time I try to create charge, get 400 Bad Request in response, regerdless if I use test flag or no. The POST body seems to be ok, I tried many combinations and none of them worked  Can you please give me ...
