👋 Thanks for reaching out
You can create PaymentLinks via Stripe API:
https://stripe.com/docs/api/payment_links/payment_links/create#create_payment_link-metadata
And pass metadata and set your custom attribute/value, You'll receive those key-value in the Checkout Session once the customer do a purchase

Thanks. My problem is that my appliaction is in classic asp. That's why I'm testing payment links without code. Is it possible to create dynamic metadata in javascript on my payment page which contains the payment link? A sample code?

Not sure I'm understanding you question here.
Meanwhile, you can create Payment Links using APIs, just in case

Hey, taking over here. Let me know if there's any follow-up Qs I can answer!

mint gale Nov 21, 2022, 10:22 AM

#

I want to use this : https://stripe.com/docs/no-code/payment-links. is there a way to pass variables from my page that contains the payment link and get them back in the endpoint? Thanks

plush wedge Nov 21, 2022, 10:27 AM

#

What kind of variables?

mint gale Nov 21, 2022, 10:32 AM

#

Ideally, I would like a link like https://buy.stripe.com/test_...?id_client=1234&id_produit=456
And be able to find these variables in my endpoint. These are dynamic variables, which will change depending on my client who has connected to my payment page. Thanks

plush wedge Nov 21, 2022, 10:36 AM

#

Ah, the query parameters? We do support some query params like that: https://stripe.com/docs/payments/payment-links#url-parameters

Share payment links

Accept payments without building a digital storefront.

mint gale Nov 21, 2022, 10:42 AM

#

Yes, something like that but with my own variables, I need to retrieve my customer's id and the product he bought to update my database from my endpoint

plush wedge Nov 21, 2022, 10:43 AM

#

Unfortunately it's not possible to pass parameters outside of what is supported today

#

You could use client_reference_id somehow I guess

mint gale Nov 21, 2022, 10:49 AM

#

I try but no way to find this variable, neither in the endpoint, nor in the logs or dashboard events. An idea?

plush wedge Nov 21, 2022, 10:50 AM

#

It's set on the checkout.session.completed events

mint gale Nov 21, 2022, 11:02 AM

#

OK great, I found it. One last question. In my endpoint, I use the address https://api.stripe.com/v1/payment_intents in GET . But how to get the contents of checkout.session.completed events?

plush wedge Nov 21, 2022, 11:03 AM

#

But how to get the contents of checkout.session.completed events?
What specific details do you need?

mint gale Nov 21, 2022, 11:07 AM

#

In my endpoint, I send myself an email with the content of the Stripe response (Json). And it starts with:
{ "object": "list"
"data": [ { "id": "pi_3..."
"object": "payment_intent"
"amount": 4900
"amount_capturable": 0
etc

but I don't get my client_reference_id variable.
This is in the checkout.session.completed which starts with:
{
"id": "evt_1...",
"object": "event",
"api_version": "2022-08-01",
"created": 1669027200,
"data": {
"object": {
"id": "cs_test_a...",
"object": "checkout.session",
"after_expiration": null,
etc

I would like to receive news from stripe about this event

plush wedge Nov 21, 2022, 11:10 AM

#

Is your webhook endpoint configured to handle checkout.session.completed events?

mint gale Nov 21, 2022, 11:12 AM

#

yes

plush wedge Nov 21, 2022, 11:13 AM

#

I'm not sure I'm understanding the issue. That event will contain the client_reference_id field from your Payment Link: https://stripe.com/docs/api/checkout/sessions/object#checkout_session_object-client_reference_id

I use this source:

<%
Set oJSON = New aspJSON

Set objhttp = Server.CreateObject("WinHttp.WinHttpRequest.5.1")
objHttp.open "GET", "https://api.stripe.com/v1/payment_intents", false '"https://api.stripe.com/v1/charges", false
objHttp.setRequestHeader "Content Type", "application/x-www-form-urlencoded"
objHttp.setRequestHeader "Authorization", "Bearer sk_test_..."
objHttp.Send
jsonstring=objHttp.ResponseText
Set oJSON = New aspJSON
oJSON.loadJSON(jsonstring)

By mail, I send myself jsonstring
and I don't get the response from checkout.session.completed with my client_reference_id variable but a long file with many payment intents and not just the last one. I hope to be clear. I can send you what I receive but it's a bit long

urban fox Nov 21, 2022, 11:26 AM

#

but a long file with many payment intents and not just the last one
that code you shared looks like it is calling GET /v1/payment_intents which is how you list all PaymentIntents on your account(https://stripe.com/docs/api/payment_intents/list?lang=curl), so that would seem expected.

mint gale Nov 21, 2022, 11:28 AM

#

It's exactly that. But what to call to get only the latest payment?

urban fox Nov 21, 2022, 11:29 AM

#

that wouldn't make sense to do since the latest payment is not guaranteed to be the one related to the webhook even you're looking at.

#

it's GET https://api.stripe.com/v1/payment_intents/pi_xxxx to retrieve a specific PaymentIntent

#

the ID pi_xxx is in the CheckoutSession object you receive in the event which you quoted earlier, in the payment_intent field of the object. https://stripe.com/docs/api/checkout/sessions/object#checkout_session_object-payment_intent

mint gale Nov 21, 2022, 11:35 AM

#

This is why I want to retrieve the variable id_client to compare it to my client's session and validate his payment. So how to make CheckoutSession object with payment link without code? Sorry, it's complicated but it's a shame that Stripe does not offer solutions for classic asp sites which are still very numerous.

urban fox Nov 21, 2022, 11:35 AM

#

I suppose but wasn't classic ASP deprecated 20 years ago?

#

So how to make CheckoutSession object with payment link without code?
not sure what that means, can you elaborate?

If using .NET and our .NET library you would write code like this to access the webhook information:

 var stripeEvent = EventUtility.ConstructEvent(json, header, secret);
switch (stripeEvent.Type)
{
  case "checkout.session.completed":
     var session = stripeEvent.Data.Object as Stripe.Checkout.Session;
     var id = session.ClientReferenceId;
     var paymentIntentID = session.PaymentIntentId;
     break;
}
....
....

mint gale Nov 21, 2022, 11:41 AM

#

By 'without code', I want to say no-code (I want to use this : https://stripe.com/docs/no-code/payment-links.). Sorry, my english is bad

urban fox Nov 21, 2022, 11:44 AM

#

which specific part are you having difficulty with? It sounds like you visited the link, made the payment and have received a webhook event and are running some code in response to that event?

#

or are you not that far yet? what have you done so far and where is your current "blocker"(thing that you are actively stuck on)?

mint gale Nov 21, 2022, 11:51 AM

#

Yes, I manage to create the link, a webhook, an endpoint. My only issue is that I get all the payments and I would just like the last one with my customer id knowing that given my business there is an extremely low risk of me receiving two orders exactly at the same time I am not Amazon ;-). So receive the last payment with, in the Json response, the id of my client. But in what I receive (all payments, the client_reference_id variable does not appear. Thank you for your patience

urban fox Nov 21, 2022, 11:54 AM

#

extremely low risk of me receiving two orders exactly at the same time I am not Amazon 😉
I'm ignoring that because sorry, it is just 100% wrong to list the most recent and if you do it that way, your site will just be very brittle. I will help you do this the correct way and retrieve the actual objects related to the event.

urban fox Nov 21, 2022, 11:54 AM

#

mint gale I use this source:  <% Set oJSON = New ...

is this the exact code of your webhook endpoint right now?

mint gale Nov 21, 2022, 11:56 AM

#

Thank you very much. Yes it is

urban fox Nov 21, 2022, 11:57 AM

#

Ok. Note this code needs to run when your server receives a HTTP POST request(the webhook) from Stripe. Does that code read an incoming HTTP POST body? If not, can you first make it do that?

In .NET that would be done like this , example from code of my own app.

[HttpPost]
      public void Index() {
          string rawBody = string.Empty;
            using (StreamReader reader = new StreamReader(HttpContext.Request.Body, System.Text.Encoding.UTF8, true, 1024, true))
            {
                rawBody = reader.ReadToEnd();
            }
            var json = rawBody; 

.....
.....

mint gale Nov 21, 2022, 12:00 PM

#

I try

#

It's OK, I can read the HHTP POST request on my endpoint

urban fox Nov 21, 2022, 12:15 PM

#

cool. So can you now take that POST body and parse that as a JSON string, into a C# object?

#

presumably it's this loadJSON function on that aspjson library.

mint gale Nov 21, 2022, 12:18 PM

#

I manage to retrieve and process this, with the infamous client_reference_id :
{
"id": "evt_1...",
"object": "event",
"api_version": "2022-08-01",
"created": 1669032447,
"data": {
"object": {
"id": "cs_test_...I",
"object": "checkout.session",
"after_expiration": null,
"allow_promotion_codes": false,
"amount_subtotal": 4900,
"amount_total": 4900,
"automatic_tax": {
"enabled": false,
"status": null
},
"billing_address_collection": "self",
"cancel_url": "https://stripe.com",
"customer_reference_id": 10888,
etc

#

No, it's not the aspjson library. I used this code :

If Request.TotalBytes > 0 Then
Dim lngBytesCount
    lngBytesCount = Request.TotalBytes
Response.Write BytesToStr(Request.BinaryRead(lngBytesCount))

End If

Function BytesToStr(bytes)
Dim Stream
Set Stream = Server.CreateObject("Adodb.Stream")
Stream.Type = 1 'adTypeBinary
Stream.Open
Stream.Write bytes
Stream.Position = 0
Stream.Type = 2 'adTypeText
Stream.Charset = "iso-8859-1"
BytesToStr = Stream.ReadText
Stream.Close
Set Stream = Nothing
End Function

urban fox Nov 21, 2022, 12:22 PM

#

ok well whatever

#

so do you know how to retrieve the value of specific fields of that object?

mint gale Nov 21, 2022, 12:22 PM

#

yes

urban fox Nov 21, 2022, 12:23 PM

#

so if I tell you "create a variable clientReferenceID and set the value to the value of the JSON key json[data][object][client_reference_id] " , would you be able to do that?

mint gale Nov 21, 2022, 12:43 PM

#

sorry for the wait. I am unable to retrieve this variable. with :
For Each xinfo In oJSON.data("data")
Set this = oJSON.data("data").item(xinfo)
Response.Write "Id: " & this.item("id") & vbCrLf
Response.Write "Amount: " & this.item("amount") & vbCrLf
Response.Write "Client reference id: " & this.item("client_reference_id") & vbCrLf
Next

ID: OK
Amount: OK
but client_reference_id, no. It should be 10888

urban fox Nov 21, 2022, 12:44 PM

#

so bear in mind I do not "speak" your ASP language so there's only so much I can help

#

but the ID is inside [data][object][client_reference_id] Does that code you shared only look at [data][client_reference_id] ?

#

seems that way to me. You need to obtain the value of the object key , in the value of the data key, that's the actual CheckoutSession object. You're one level too high right now I think.

mint gale Nov 21, 2022, 1:01 PM

#

That's right, it's ok, I have it !

#

I have to go. Thank you for your help, I will continue to dig but I have already made good progress thanks to you. Thanks

urban fox Nov 21, 2022, 1:29 PM
