To use this newer integration, you must also migrate to the Checkout API.\n\nImplement a fallback implementation in case the issuer does not support 3D Secure 2 authentication-only integration yet. In the response, you get the authentication data that you need to authorise the payment with another PSP or acquirer.\nIf after the authentication you decide to\u00a0process the payment with us, you can also\u00a0continue with the payment authorisation\u00a0with Adyen.\nBefore\u00a0you begin\nBefore you begin to integrate, make sure you have followed the Get started with Adyen guide to:\n\nGet an overview of the steps needed to accept live payments.\nCreate your test account.\n\nAfter you have created your test account:\n\nGet your API Key. Save a copy\u00a0as you'll need it for API calls you make to the\u00a0plataforma de pagamentos da Adyen.\nRead and understand the\u00a0full 3D Secure 1 Classic API integration guide.\u00a0\n\nStep 1: Submit a payment authentication request\nSubmit an authentication request with a\u00a0 \/authorise\u00a0call containing the\u00a0required 3D Secure 1 parameters and the authenticationData.authenticationOnly parameter:\n\nauthenticationData.authenticationOnly:\u00a0Set this to true.\n\n\n    \n\nYou'll receive a response containing:\n\nresultCode: RedirectShopper. This means that you have to perform the 3D Secure authentication flow.\n\nFor a complete list of\u00a0resultCode\u00a0values and the actions that you need to do, see\u00a0Result codes.\n\n    \n\nStep 2: Perform the 3D Secure 1 authentication flow\n\n\nRedirect the shopper to the card issuer to perform authentication. After a successful authentication, the card issuer returns the shopper to your site and sends an HTTP POST to your TermUrl containing the following:\n\nMD: Payment session identifier.\nPaRes: Payment authorisation response.\n\n\n\nGet the MD and PaRes values and proceed to submit the authentication result.\n\n\n\nIf after performing the authentication you decide to continue the payment authorisation with Adyen, skip the next step proceed to Authorise the payment with Adyen instead.\n\nStep 3: Submit the result and get the authentication data\n\nSubmit the authentication result in an  authorise3d request:\n\n\nmd: Payment session identifier, MD, returned by the card issuer in the previous step.\npaResponse: Payment authorisation response, PaRes, returned by the card issuer in the previous step.\n\nauthenticationData.authenticationOnly:\u00a0Set this to true.\n\n\n\n\n\nYou'll receive a response containing:\n\nresultCode: If the authentication process has finished, you receive AuthenticationFinished.\n\nadditionalData.threeDAuthenticatedResponse: Indicates the results of the authentication. The value Y means that authentication was successful. If you get another value, see the list of possible values to learn what it means.\n\n\n\n\n\n\nIf you received Y in additionalData.threeDAuthenticatedResponse, you can continue to the next step to authorise the payment.\n\n\nSee our API reference to learn more about the response parameters and how the values map to 3D Secure specifications.\n\nOptional: Authorise the payment with Adyen\nIf after completing the authentication flow you decide to proceed with authorising the payment with Adyen, you can still switch and continue with a payment authorisation.\nMake a POST\u00a0 authorise3d\u00a0request from your server and include the following parameters:\u00a0\n\nauthenticationData.authenticationOnly:\u00a0Set this to false.\n\n\n    \n\nYou'll receive\u00a0Authorised\u00a0as the\u00a0resultCode\u00a0if the payment was successful.\n\n    \n","type":"page","locale":"pt","boost":14,"hierarchy":{"lvl0":"Home","lvl1":"Online payments","lvl2":"Classic integrations for Ecommerce","lvl3":"Classic API integration","lvl4":"3D Secure authentication","lvl5":"3D Secure 1 and 2 redirect authentication","lvl6":"Authentication-only integration"},"hierarchy_url":{"lvl0":"https:\/\/docs.adyen.com\/pt","lvl1":"https:\/\/docs.adyen.com\/pt\/online-payments","lvl2":"https:\/\/docs.adyen.com\/pt\/online-payments\/classic-integrations","lvl3":"https:\/\/docs.adyen.com\/pt\/online-payments\/classic-integrations\/classic-api-integration","lvl4":"https:\/\/docs.adyen.com\/pt\/online-payments\/classic-integrations\/classic-api-integration\/3d-secure-authentication","lvl5":"https:\/\/docs.adyen.com\/pt\/online-payments\/classic-integrations\/classic-api-integration\/3d-secure-authentication\/3d-secure-1","lvl6":"\/pt\/online-payments\/classic-integrations\/classic-api-integration\/3d-secure-authentication\/3d-secure-1\/3d-secure-1-authentication-only"},"levels":7,"category":"Online Payments","category_color":"green","tags":["Authentication-only","integration"]},"articleFiles":{"authorise3d-request-2793971518.js":"<p alt=\"\">authorise3d-request-2793971518.js<\/p>"}}
