Question:

Fix Stripe API payload Format issue

Problem:

I'm trying to integrate the Stripe API in my Python application; therefore, I'm not using the Python Stripe library but instead using Stripe API endpoints only. The issue I'm facing is with the payload especially when sending array or nested dictionary like below:

def create_payment_intent(api_key, authorized_amt):

headers = {

"Authorization": f"Bearer {api_key}",

"Content-Type": "application/x-www-form-urlencoded",

}

payload = {

"amount": authorized_amt,

"currency": "usd",

"capture_method": "manual",

"payment_method_types": ["card"],

}

res = requests.request(

"POST", url=PAYMENT_INTENT_URL, data=payload, headers=headers

)

payment_intent = res.json()

return payment_intent

when I run this I get error below:

{'error': {'message': 'Invalid array', 'param': 'payment_method_types', 'request_log_url': 'https://dashboard.stripe.com/test/logs/req_r9TIQ1wnYF8Gi4?t=1699501606', 'type': 'invalid_request_error'}}

But when I change its format like below it works:

"payment_method_types[]": "card"

This is same for objects also I will have to send like below to make it work:

payload= {

"card[number]": 4242424242424242,

"card[exp_month]": 12,

"card[exp_year]": 2034,

"card[cvc]": 999

}

Solution:

That's because the data type that Stripe API endpoint expects is application/x-www-form-urlencoded.
