payment | A microservices-demo service that provides payment services

you can use advanced where clause with closure for this.

You can access the client_reference_id by retrieving the Checkout Session on the success page: https://stripe.com/docs/payments/checkout/custom-success-page

However a much easier solution would be to just encode your variable directly into the success URL:

From the coinpayment documentation

It is implemented by making a standard HTTP POST (application/x-www-form-urlencoded) call over a https:// or http:// URL to a script or CGI program on your server.

In your Express server, you may need to add the middleware to parse requests in urlencoded format:

This is not a dumb question at all. However, GTM by itself does not persist anything, unless you create a tag that writes the utm parameters to cookies or local storage. But then this is probably not relevant for your case, because with the proper configuration, Google Analytics does persist the values by itself (in a manner of speaking).

GA calculates sessions on the GA server by connecting requests with the same client id (or user if, if set). It can look at the first pageview in the session and inspect the url for campaign information such as utm parameters. That way, it does not require that utm parameters are persisted in the browser, the only thing that needs to be stored (by default in a cookie) is the client id.

There is one caveat, that GA starts a new session when the campaign info changes. When you visitor is rerouted via an external domain for payment, a new session will start with the external domain as referrer and the marketing channel set to referrer. To avoid that, you need to add the payment gateway domain to the referral exclusion list (if you use Universal Analytics, there is a similar mechanism for Google Analytics 4), so GA ignores the external domain when the session and channel attribution is calculated. But that's a setting in the Google Analytics interface, you do not need to make changes to GTM for that.

See, here you are trying to click on an iframe (Check the last part of xpath):

So I generated the form recursively so I can freely add and remove any items from the form and the solution is here: Generate form trough loop

This is how I generated my table from the form recursively:

You should be able to add the cc in the options object.

As per Lombok documentation (https://projectlombok.org/api/lombok/AllArgsConstructor.html):

An all-args constructor requires one argument for every field in the class.

Obviously you haven't provided id as a constructor argument.

If I understand correctly, it is the total row that you really care about. You can calculate the first two columns by unnesting both tags and payments in parallel.

Then for the total, unnest the payments without the tags:
