**Last updated**: 11 November 2025 | [**Change log**](/products/card-payments/changelog/) # Get Started with our Payments API ## Set your headers Setting your headers is an important part of an API request. The headers represent the meta-data associated with your API request. ``` Authorization: {your_credentials} Content-Type: application/vnd.worldpay.payments-v5+json ``` | Header | Description | | --- | --- | | `Authorization` | The `Authorization` header is used for authentication and identification of our merchants within Access Worldpay. You **must** use the `Authorization` header for any request you send to our Payments API. | | `Content-Type` | The `Content-Type` header is required if the request you're sending includes a request body, and if the HTTP method is a `POST` or a `PUT`. | Note Replace `{your_credentials}` with your base64-encoded Basic Auth username and password. To get your Access Worldpay credentials contact your Implementation Manager. ## Next Steps We have reviewed our API Principle approach and consider our resources stable and unlikely to change. This means you can skip querying the root resource for a quicker integration and [POST directly to the API resource](/products/card-payments/v5/authorize-a-payment). If you do want to discover all available resources, you can expand the below section "Query the root resource" for further steps. details summary Query the root resource Our APIs guide you by providing you with links to the next available actions. To discover and start using our APIs you can query the root resource first. This returns the available resources within Access Worldpay. ### Request GET `https://try.access.worldpay.com/` Note No request body is needed for this request. ### Response You receive all our available API resources in the response. { "_links": { "payments:authorize": { "href": "https://try.access.worldpay.com/payments/authorizations" }, "service:payments": { "href": "https://try.access.worldpay.com/payments" }, "service:sessions": { "href": "https://try.access.worldpay.com/sessions" }, "service:tokens": { "href": "https://try.access.worldpay.com/tokens" }, "service:verifications/accounts": { "href": "https://try.access.worldpay.com/verifications/accounts" }, "service:verifications/customers/3ds": { "href": "https://try.access.worldpay.com/verifications/customers/3ds" }, "service:verifiedTokens": { "href": "https://try.access.worldpay.com/verifiedTokens" }, "service:fraudsight": { "href": "https://try.access.worldpay.com/fraudsight" }, "service:exemptions": { "href": "https://try.access.worldpay.com/exemptions" }, "service:payouts": { "href": "https://try.access.worldpay.com/payouts" }, "service:payments/alternative/direct": { "href": "https://try.access.worldpay.com/payments/alternative/direct" }, "service:payments/alternative/action/paypal": { "href": "https://try.access.worldpay.com/payments/alternative/action/paypal" }, "service:payments/alternative/action/ideal": { "href": "https://try.access.worldpay.com/payments/alternative/action/ideal" }, "service:payouts/accounts": { "href": "https://try.access.worldpay.com/payouts/accounts" }, "service:payouts/events": { "href": "https://try.access.worldpay.com/payouts/events" }, "service:moneyTransfers": { "href": "https://try.access.worldpay.com/moneyTransfers" }, "service:foreignExchange": { "href": "https://try.access.worldpay.com/foreignExchange" }, "service:accounts/statements": { "href": "https://try.access.worldpay.com/accounts/statements" }, "service:accounts/balance": { "href": "https://try.access.worldpay.com/accounts/balance" }, "service:accounts/transfer": { "href": "https://try.access.worldpay.com/accounts/transfer" }, "curies": [ { "href": "https://try.access.worldpay.com/rels/payments/{rel}", "name": "payments", "templated": true } ] } } ## Query the payments root resource Querying the root resource returns the links to the available actions you can perform with our services. ### Request GET `https://try.access.worldpay.com/payments` Note No request body is needed for this request. ### The response { "_links": { "resourceTree": { "href": "https://try.access.worldpay.com/payments/resourceTree" }, "payments:authorize": { "href": "https://try.access.worldpay.com/payments/authorizations" }, "payments:cardOnFileAuthorize": { "href": "https://try.access.worldpay.com/payments/authorizations/cardOnFile" }, "payments:migrateRecurringAuthorize": { "href": "https://try.access.worldpay.com/payments/authorizations/migrateRecurring" }, "payments:migrateCardOnFileAuthorize": { "href": "https://try.access.worldpay.com/payments/authorizations/migrateCardOnFile" }, "payments:migrateCardOnFileSale": { "href": "https://try.access.worldpay.com/payments/sales/migrateCardOnFile" }, "payments:events": { "href": "https://try.access.worldpay.com/payments/events" }, "payments:recurringMandate": { "href": "https://try.access.worldpay.com/payments/recurringMandates" }, "curies": [ { "name": "payments", "href": "https://try.access.worldpay.com/rels/payments/{rel}", "templated": true } ] } } Note Use the action links returned to send your request to one of our resources.
