Getting error while creating peyment(Stripe) - request

Question

I'm using this code to create payment(Stripe) in the tab Pre-request script
pm.sendRequest({
url: 'https://api.stripe.com/v1/tokens',
method: 'POST',
headers: {
'Authorization': 'Bearer pk_test_...',
'Content-Type': 'application/x-www-form-urlencoded'
},
data: {
'card[number]': 2223003122003222,
'card[exp_month]': 12,
'card[exp_year]': 2020,
'card[cvc]': 123
}
And getting this error:
You did not provide an API key. You need to provide your API key in the Authorization header, using Bearer auth (e.g. 'Authorization: Bearer YOUR_SECRET_KEY').
everything works as a separate request

Answer 1

In my case, I had my dotenv import come after I was calling my secret key.
const stripe = require("stripe")(process.env.STRIPE_SECRET);
require ("dotenv").config();
Reversing those two lines of code was what I needed to do.
require ("dotenv").config();
const stripe = require("stripe")(process.env.STRIPE_SECRET);

Answer 2

I think you're after something like this:
pm.sendRequest({
url: 'https://api.stripe.com/v1/tokens',
method: 'POST',
header: {
'Authorization': 'Bearer pk_test_......',
'Content-Type': 'application/x-www-form-urlencoded'
},
body: {
mode: 'urlencoded',
urlencoded: [
{ key: "card[number]", value: 2223003122003222 },
{ key: "card[exp_month]", value: 12 },
{ key: "card[exp_year]", value: 2020 },
{ key: "card[cvc]", value: 123 },
]
}
})
Your issue was around the headers key as it should be header. Also, the way the payload was written seemed like it would error(?). I tried this code locally and saw the response back from Stripe.
You might want to change the token credentials now that you've posted it here.
