I have been trying to create my own external application using Oauth, but I get to filling out the details for the callback URL and Identity link URL (and the name), which creates fine, but when I go to activate the integration I get greated with a "Sorry, something went wrong. Please try again later.", and the only error I get is from the debug.log file within Magento.

[2020-10-08 16:02:22] main.DEBUG: URI '/admin_13rc6p/admin/integration/tokensExchange/id/8/reauthorize/0/key/0ed0706f89d9950b82de796f028519b5f67df267cb337095fa255da0d52db82b/?form_key=hljjqv6G0SmuLm9g&_=1602172897038'' cannot be accessed with GET method (Magento\Integration\Controller\Adminhtml\Integration\TokensExchange) [] []
[2020-10-08 16:02:22] main.DEBUG: Request validation failed for action "Magento\Integration\Controller\Adminhtml\Integration\TokensExchange\Interceptor" {"exception":"[object] (Magento\\Framework\\App\\Request\\InvalidRequestException(code: 0): Invalid request received at /var/www/magento-install.com/lib/internal/Magento/Framework/App/Request/HttpMethodValidator.php:69)"} []

(I replaced my domain with magento-install.com)

I have followed the guides on https://devdocs.magento.com/guides/v2.4/get-started/authentication/gs-authentication-oauth.html, but still no luck with getting it to activate.

Any suggestions?

Got late, but hope this solution will help to others. Getting same above issue on Magento 2.4.2 with Klaviyo Integration.



use Magento\Framework\App\Action\HttpGetActionInterface;

class TokensExchange extends Integration implements HttpPostActionInterface,HttpGetActionInterface

Added additional interface HttpGetActionInterface Please override this file to local
