3ds | Javascript front-end to the titledb API

I have 3 different services like valid,jsc,test and i have created 3 different subnets and 3 different security groups for the same.Now i want to crate 3 instances for each service with respective subnet id and security group.How to achieve this?

I have a file I'd like to parse to json. First item looks as follows:

guys! First time touched stripe got confused with such problem - Need to make flow for paying for combination PRODUCT + SUBSCRIPTION in one payment (with 3d secure flow if it is req) and to send one total invoice for customer. So I've made such a plan:

1. Create stripe customer
2. Create payment method based on card elements
3. Attach payment method to customer
4. Create subscriptions.
5. Create paymentIntent (with return url prop if 3ds is required) to hold money on customer's card.
6. Capture money from customer's card when i got info from shipping service that order status is "sent".

But when i started point 4 of my list i got confused because of subscription logic on stripe. As i got it from docs, subscription will create it's own payment intent, own invoice and will ask for own 3ds. So i'm rather confused, because it look like user will need to pass two 3ds for product and sub, will pay for both in two different payments and will get two invoices. What am i missing? Why subscription cannot be attach to "main" payment, be paid by it after 3ds passed and be activated after that? Why should i split them and make it more complex than one sigle payment/invoice?

how it is looking from code point of view (just mockup without any side operations):

1. Create a user

I'm trying to allow customers to change their Stripe plan via the API, but 3D Secure test cards are failing even though they should be authenticated for future use.

My API call is as follows:

After reading 3DSecure GlobalPay documentation, my team opted for an integration via JSON, with our own client-side implementation, as we already have on production another integration with another 3DS verification service . For what's worth, we are implementing it using Vue.JS and Laravel.

As it can be seen in their documentation, GlobalPay sample request is:

I have and app that uses connected accounts with Stripe. I need to store information about which Stripe account is linked to the specific client in my app. So my current workflow is:

1. I set a Stripe Account Id to the client of my app in Database
2. On the specific page, my Frontend sends request about which Account Id is linked to the specific client
3. I send a Stripe Account Id as a response to my Frontend
4. I process Card information with the connected account on my Frontend and send the Token to my Backend
5. On the backend, I create Source and retrieve it back to Frontend
6. On the Frontend, I handle the possible 3DS and send a Source back to my Backend
7. On the backend, I finish the payment and send status back to my Frontend

So, my question is - Is there any possible security risk during the process? I could not figure out any other way of passing Account Id information to the frontend. I need to initialize Stripe on Frontend with a specific Account Id to check Credit card data via Stripe Elements. Without the Account Id in my Frontend, I cannot create Card payment linked to the specific connected Stripe Account, so I think, there is no other way - Am I wrong?

As clients in my application changes, there is no possibility to store an Account Ids in an ENV file, I just have to get it from my server somehow.

I also tried to check Card info via Stripe elements using just PK stored in my ENV file, but then, when I wanted to finish payment with a connected Account, the process failed.

Do you guys have any secure workflow for this situation?

I have a integration test for my razor web application with custom WebApplicationFactory:

I am trying to understand some code and I was hoping someone could give me a basic overview of what this code means. The first bit of code I don't understand is this:

So, i don't know if the title makes it easy to understand, but basically i want to change this to the minimum of code possible:
