hi! the fingerprint field works the same in test mode as in livemode. What exact issue are you facing?

[grim osprey]

I can see the fingerprint in stripe's background, but I query it through the API, but I can't get any information about the card. Why?

PaymentMethod paymentMethod = PaymentMethod.retrieve(pmId);

Is it the same? In the current test environment, the callback information obtained by the front-end after the successful payment, "fingerprint":"[redacted]", what does this mean?

[fair nimbus]

but I query it through the API, but I can't get any information about the card.
what does that mean? I see you made a call to the API via our Java SDK. The finrgerprint would be returned in the response(under .getCard().getFingerprint() as far as I remember). What code are you using, what did you expect to see, what did you see instead?

In the current test environment, the callback information obtained by the front-end after the successful payment, "fingerprint":"[redacted]",
where precisely are you seeing that?

but like in general yes, the fingerprint is not returned on the frontend(when using publishable API keys), that's expected, it is only returned when using secret API keys on the backend

[grim osprey]

Credit card after successful callback results see

fingerprint was this delivered to us at webHook? No sign of it so far

response={"billingDetails":{"address":{}},"cardPresent":{},"created":1714026342,"id":"pm_1P9LkY04cT6YoXkE8Q9ha329","livemode":false,"metadata":{},"object":"payment_method","type":"card_present"}

If you look at the data returned, there are no crad entities

[fair nimbus]

what webhook event are you expecting? if you paid a PaymentIntent with a PaymentMethod, then sure, you will get events like payment_intent.payment_succeeded . fingerprint won't be in the top-level event data, since it lives inside the Charge or PaymentMethod object, you have to make some extra API calls.

[fair nimbus]

and where does this object come from?

[grim osprey]

Now I want to get this fingerprint, think of three ways:

1. webHook;
2. Callback received after the front end swipes the card successfully;
   3, the server side according to pmId, actively query;

What's your suggestion? Which way is more appropriate?

Have been paid for the successful order inside the acquisition

[fair nimbus]

1 or 3 works.

[grim osprey]

but 1, I can't see a callback for this fingerprint information

If it is 3, do I need to use charge or paymentMethod?

[fair nimbus]

listen to e.g. payment_intent.payment_succeeded , call Charge.retrieve() on the value of https://docs.stripe.com/api/payment_intents/object#payment_intent_object-latest_charge , look at the fingerprint in https://docs.stripe.com/api/charges/object#charge_object-payment_method_details-card-fingerprint .

or listen to payment_intent.payment_succeeded and call PaymentMethod.retrieve() , or so on.

[fair nimbus]

they both work.

[grim osprey]

So far I'm just PaymentMethod.retrieve(), but I don't get the card information

Or is it necessary to query when the callback comes back, and now it is not at the callback time, so the query cannot be queried?

[fair nimbus]

again, what does that mean?
What exact code are you using, what did you expect to see, what did you see instead?

There is a field that has the fingerprint:
https://docs.stripe.com/api/payment_methods/object#payment_method_object-card_present-fingerprint

[grim osprey]

I have verified that the fingerprint can be queried using charge, but cannot be queried using paymentMethod

[fair nimbus]

so please show me the exact code you've written to query it, and share an example pm_xxx ID you've used with that code.

[grim osprey]

One more question, just to be clear, is each card going to have a unique fingerprint? Or will some cards have no fingerprints?

PaymentMethod paymentMethod = PaymentMethod.retrieve(pmId);

[fair nimbus]

is each card going to have a unique fingerprint?
yes
Or will some cards have no fingerprints?
no, they all have a fingerprint

[fair nimbus]

sure, and then what?

what do you do with the variable paymentMethod to look at and log the values of the fields you're interested in?

[grim osprey]

pm_1PBCl204cT6YoXkEfsOHuBbX

[fair nimbus]

for example paymentMethod.getCardPresent() etc. Please share the complete code you're using.

[grim osprey]

I don't care if the paymentMethod gets the fingerprints, I can get them through the Charge

[grim osprey]

it will return null

There is one last question to confirm, that is, webHook will not return the fingerprint, so we need to actively query the API, right?

[fair nimbus]

you would call the API as part of your code that handles the webhook yes, so you can get more detail.

[grim osprey]

Okay, so that means you need to actively query the API for fingerprints, right

Okay, thank you so much for your support. Love you
