支払い方法を追加する際、エラーが発生するのはなぜですか？トラブルシューティング

Check the exact error code, then retry within 60 seconds. This quick step clears transient processor hiccups and prevents duplicate charges on your account. If the error repeats, note the code, the time, and the platform you used, then contact support with those details to speed up resolution.

Common causes include mismatched card data, expired cards, or country restrictions on your подписку. Verify the card number, expiry, CVC, and billing address in your merchant portal. If a 3D Secure flow is required, complete it to authorize the payment. For custom flows, confirm the redirect URL is correct and that the domain is accessible; you can even check the whois record to confirm domain ownership if necessary.

For developers and operators: inspect integration logs and API responses, with signature verifications. Look at the timeline of events around the attempt, and verify that your oracle-based payment module is up to date. Ensure the request contains a valid signature and that the payment method is allowed for the target region.

Check domain and DNS: the redirect must point to the correct endpoint, and the DNS should resolve within your hosting environment. If you employ a hosted checkout, confirm the merchant account settings and any attribution data associated with the transaction. If you encounter a persistent error, gather user feedback and prepare a concise incident report for support.

When you contact support, provide your account ID, the exact error text, the reproduction steps, and a timestamp from the timeline. Include any attribution data, device and browser details, and a sample signature. In your message, mention подписку and завершения, and, if you suspect a problematic payment method, отключите it and re-add after a short interval. Submit feedback through the support portal to help diagnose the issue faster.

Validate Required Fields and Data Types in the Payment Method Payload

Verify required fields and data types in the payment method payload before submission. Build a strict schema and enforce checks on both client and server to prevent invalid data from reaching processing. Validate in real time so users see errors instantly, reducing время and frustration. If a user edits a field, ensure updating validations run; otherwise a missing or mismatched field can lie undetected until processing, creating проблемы later. Surface checks (проверки) directly in the form and in the console so you stay trusted and ready to act.

Define required fields and expected types for the payload. For example, the processor expects: cards[number] as string; cards[exp_month] as integer 1-12; cards[exp_year] as four-digit integer; cards[cvc] as string of digits with length 3-4; billing_details[name], billing_details[email], billing_details[address][line1], billing_details[address][city], billing_details[address][postal_code]. If a field is missing or the type is wrong, trigger invalid and surface a clear message in the form. Also ensure the payload matches the associated schema used by your third-party processor. If a field doesnt exist, present a helpful note in the console and in the UI; such checks reduce проблемы before submitting and keep your self-serve flow smooth for users.

Validation guidelines

Implement a Luhn check for cards; verify exp date is not in the past; validate CVC length; enforce string types for numbers that include formatting; use switch logic to handle different card brands; ensure optional fields are marked as such and validated if present. Validate the payload structure and data types before you accept it, and note any invalid entries with a helpful message. This approach reduces problems and helps users move forward until the issue is resolved. Also keep a record noted for what failed to learn and refine your rules.

Even if client-side checks pass, perform server-side validation to prevent spoofing and to enforce your rules. Re-check all required fields (проверки) and data types on update; if a field is edited, re-run checks (edit) and do not update until the payload passes. The switch between accepted and declined states should be driven by validated data; if the card doesnt exist in your system or the processor returns a decline, you can show a direct, helpful message. Logs in the console and noted errors help you learn and adjust the validator. For teams using udrp flows, align the checks with that process to avoid surprises for users and support staff.

Practical steps for implementation

Implement both client-side and server-side validation. Use a JSON schema or a validation library to align with your processor’s expectations. Steps: define the schema, wire form checks to catch invalid types early, perform server-side re-validation on payload arrival, surface helpful notices in the UI for self-serve troubleshooting and in the console for developers, test with common scenarios and example payloads, switch environments as needed, and monitor results. Include tests for cards, such as different brands, invalid numbers, expired dates, and incorrect CVC. Such a disciplined approach reduces problems and keeps your workflow smooth for trusted operations and less downtime with время to spare. Learn from each failure to improve your checks and keep users in control.

Example payload for validation: cards: { number: ‘4242424242424242’, exp_month: 12, exp_year: 2026, cvc: ‘123’ }, billing_details: { name: ‘Alex Doe’, address: { line1: ‘100 Market St’, city: ‘Aurora’, postal_code: ‘12345’ } }. If this payload passes all checks, processing proceeds; if not, the form highlights invalid fields and the console notes the exact problems (проблемы) for quick correction. This direct feedback helps you learn and refine your rules, and keeps you from switching to a deferred update path that could cause a decline later.

Verify Card Information: Number, Expiration Date, CVC, and Luhn Check

Directly validate the card number, expiration date, and CVC in real time before the form is saved. Run a Luhn check on the number and reject any input that fails; this reduces failed purchases for every customer and keeps data saved and secure. Samples from trusted issuers can guide formatting and error messages. Thanks for helping users complete payments smoothly.

Card Number and Luhn Validation

Under the hood, strip spaces, dashes, and dots from the number, then apply the Luhn algorithm. If the check fails, show a clear error under the field and prompt the user to re-enter (edit). Use the API parameter number to align with your backend and avoid confusion for the owner or the app. This approach protects the data, prevents unwanted charges, and helps customers move from saved cards to Pays with confidence. The steps ниже outline the checks to provide помощь to users and keep checkout reliable for every transaction.

Expiration Date, CVC, and Data Handling

Validate the expiration: month must be 01–12 and the year must be in the future. Support formats per your parameter (MM/YY or MM/YYYY); if invalid, show a concise message and require correction before proceeding with the transaction. For CVC, require 3 digits for most cards and 4 digits for AmEx; if the value is missing or incorrect, prompt for re-entry (edit). Do not log or store данные sensitive parts of the card; store only tokens and restrict access. Keep the customer’s information under trusted controls and confirm that the process for the next purchases is done correctly, ensuring a smooth flow for покупкi and access to the app’s features.

Ensure Billing Address and Cardholder Details Align with the Payment Gateway

Update the billing address and cardholder name to match gateway records before submitting a payment request. Maintain current information in your system to prevent declines and reduce the number of failed requests.

When the gateway sees mismatched data, it can return a code that blocks the charge and leaves logs retained for review. Keep a clear path for retries without exposing customers to confusing errors or lengthy пересылки через службу поддержки. If висит проблема, если you see a mismatch, fix it in the source data before you attempt another request and avoid unnecessary копирования полей.

Follow these actionable steps to bring billing data in line with the payment gateway and minimize edge-case errors in subscriptions and single payments alike.

• Confirm current billing information in your CRM matches the gateway’s required fields, including number, street address, city, state/region, postal code, and country code. If differences exist, edit the record so the gateway receives a single, consistent set of data.
• Verify the cardholder name exactly as it appears on the card. Even a minor discrepancy can trigger an issuing or gateway mismatch that leads to a failed request. If needed, use the full legal name and avoid initials.
• Map address fields to the gateway’s format. Some gateways require a two-letter country code and a fixed postal code format. Ensure the number of digits and separators align with the gateway’s general terms and validation rules.
• Test with samples and current data in a sandbox environment. Record the inputs, including the request payload and the response code, so you can reproduce the scenario if a real transaction fails.
• When exchanging information with the gateway, attach a clear screenshot of the request and response. Screenshots help your team verify that the right fields were sent and can speed up legal or support inquiries if a dispute arises.
• For subscriptions, ensure the billing address used for renewal remains consistent across retries. Inconsistencies can cause back-to-back failed charges and affect retained customer data or failed access to services.
• If the gateway reports a mismatch, use the edit option to correct the record and then re-submit instead of creating a new customer profile. Otherwise, duplicate data can complicate subscriptions and legal compliance checks.
• Review related requests and terms on the gateway side. Ensure that the issued code, error text, and any policy notes are understood so you can respond with the appropriate updates to the customer and the back-end system.
• When things still dont work after edits, check the issuing bank’s guidelines. Sometimes the bank blocks a transaction for address verification reasons, and you may need to ask the customer to verify the card details or try an alternative payment method.

Keeping the billing address and cardholder details aligned reduces friction and improves the success rate of current transactions, especially for подписки and recurring payments. Maintain clear information flow, document the steps you took with samples, and remain compliant with legal and information-retention requirements so that future requests stay smooth and traceable.

Check Payment Method Object Structure for API and Schema Compliance

Verify the Payment Method object against the API schema before sending a request. Align top-level fields (id, type, status) and the nested method details (card, bank_account, or wallet) with the latest spec. Use a filter to compare the payload against the example samples; if a mismatch occurs, the header and message in the API response will clearly indicate the issue and help you prevent a faulty transaction, thats why a strict schema check matters.

Based on the timeline of updates, ensure your payload matches the current samples and supports merchants and developers workflows. когда поле payment_method_type отсутствует, the message will indicate a required field. возникли concerns, обратитесь к документации, чтобы определить источник несоответствия. Если возникли concerns, используйте всплывающие validation messages and the associated image fields to keep подписки processing stable. When clicking validate in your testing environment, verify that the response header matches the expected structure and that samples and example align. This approach reduces время to diagnose issues and speeds up updates.

API and schema validation steps

Check required fields, data types, and nesting: id, type, status, and the details object. Ensure the image field, if present, uses the correct image URL or hash. Validate that the metadata map uses only allowed keys and string values. Validate time-related fields for proper ISO8601 format. Use a consistent order to make diffs easy and set a baseline header as to the content-type and API version. This helps prevent transaction failures and keeps teams of merchants and developers aligned.

Practical examples and samples

Refer to the official samples to confirm structure. A typical example includes header, message, and the associated fields. When clicking through the sample payloads in the docs, the image reference and transaction object should match exactly. If you see a mismatch, apply the filter to isolate the field and adjust accordingly, then re-run. These steps reduce confusion for merchants and help teams learn quickly, while events in the timeline show when updates went live and what changed in each release. If возникли concerns about compatibility with a third-party platform, validating with whois data is not required here.

Interpret Common Error Codes and Server Responses for Troubleshooting

Start by reading the exact error code and the header in the server response, then map it to the right action. Note the number, the message, and any detail fields; this info guides the next steps and helps you diagnose quickly. In normal flows, the code aligns with a known category, making it easier to respond. If you see a code that reads 400, 401, 403, 404, 429, or 5xx, follow the category-specific checklist.

400 Bad Request means the payload failed validation. Remove fields that are not required and test with a minimal payload. Validate the expiration and validity of the card data (карта) you submit, and ensure the dataset contains only accepted keys. If you test in a local environment, keep the payload consistent with the provided API schema, and verify the number of digits on the card entry matches the supported formats.

401 Unauthorized or 403 Forbidden indicates access issues. Confirm the access token or API key, and refresh credentials if needed. Check the profile details used for the request and confirm there are permissions on the domain or partner domain you access. If the profile is missing required scopes, you will see access denied until it is granted.
