Creating Your First Checkout Session
- Node.js SDK
- Python SDK
- REST API
API Response
All methods above return the same response structure:session_id is guaranteed to be present. Two cases return additional or fewer fields:
payment_method_idwas provided — the charge is processed immediately andcheckout_urlisnull. Use the returnedpayment_idinstead.confirm: truecreated the payment at session-creation time — the response also includespayment_id,client_secret, andpublishable_keyfor use with the Dodo Payments checkout SDK.
The generated
checkout_url is single-use and expires within 24 hours. Don’t cache or reuse it across customers or payment attempts — create a new checkout session whenever you need a fresh link.1

checkout_url from the API response.2
Redirect your customer

If true, finalizes all session details immediately. API will throw an error if required data is missing.
array
Checkout session में एक या अधिक stacked discount codes लागू करें। Codes को array order में लागू किया जाता है (पहला code शुरुआती कीमत को कम करता है, दूसरा पहले से discounted कीमत को कम करता है, और इसी प्रकार आगे), और प्रति session अधिकतम 20 codes लागू किए जा सकते हैं। जब Purchasing Power Parity सक्षम हो, तो शुरुआती कीमत base price नहीं, बल्कि PPP-adjusted amount होती है।
The singular
discount_code field below is deprecated but still fully supported — existing integrations continue to work without changes. It cannot be combined with discount_codes in the same request. Migrate to discount_codes when convenient to take advantage of stacking.string

Previewing Checkout Sessions
Before creating a checkout session, you can preview the pricing breakdown including taxes, discounts, and totals. This is useful for displaying accurate pricing to customers before they proceed to checkout.Preview किया गया
current_breakup.subtotal पहले से ही product पर लागू होने वाले Purchasing Power Parity और Charm Pricing को दर्शाता है।जब cart में subscription product होता है, तो preview response एक
next_billing_date भी लौटाता है — यह आगामी billing date का preview होता है, ताकि subscription बनने से पहले आप इसे दिखा सकें। इसकी गणना वर्तमान समय के सापेक्ष की जाती है: trial लागू होने पर now + trial period, अन्यथा now + one payment frequency। केवल one-time वाले carts के लिए यह field शामिल नहीं की जाती। यह preview समय पर आधारित एक अनुमान है; authoritative next_billing_date subscription सक्रिय होने पर सेट किया जाता है।Preview
trial_period_days (प्रभावी trial अवधि, चाहे free हो या paid) और trial_amount (discounts के बाद प्रति unit trial charge, price currency की minor units में) भी लौटाता है। trial_amount केवल paid trial के लिए मौजूद होता है और free trial या किसी trial के न होने पर null होता है। आज वास्तव में देय taxed total के लिए current_breakup का उपयोग करें।- Node.js SDK

Dynamic Links से Checkout Sessions पर जाना
मुख्य अंतर
पहले, Dynamic Links का उपयोग करके payment link बनाते समय, आपको customer का पूरा billing address देना आवश्यक था। Checkout Sessions के साथ अब यह आवश्यक नहीं है। आपके पास जो भी जानकारी हो, आप उसे भेज सकते हैं और बाकी काम हम संभाल लेंगे। उदाहरण के लिए:- यदि आपको customer का केवल billing country पता है, तो बस वही दें।
- checkout flow customer को payment page पर ले जाने से पहले missing details अपने-आप एकत्र करेगा।
- दूसरी ओर, यदि आपके पास पहले से सभी आवश्यक जानकारी है और आप सीधे payment page पर जाना चाहते हैं, तो आप पूरा data set भेज सकते हैं और अपने request body में
confirm=trueशामिल कर सकते हैं।
Migration Process
Dynamic Links से Checkout Sessions पर migrate करना सीधा है:1
Update your integration
अपने integration को नई API या SDK method का उपयोग करने के लिए update करें।
2
Adjust request payload
Checkout Sessions format के अनुसार request payload को समायोजित करें।
3
That's it!
हाँ। आपकी ओर से किसी अतिरिक्त handling या विशेष migration steps की आवश्यकता नहीं है।
