Good day @myrmicat, Thank you for contacting PayPal community. Our sincere apologies for the inconvenience caused. By default, PayPal system will generate Smart button code in Sandbox environment and merchant can test the integration using sandbox accounts. Merchants need to create LIVE REST API credentials and pass/enter the LIVE API credentials in the Smart button code in order to receive payments in LIVE production. I request to please follow the below steps to create LIVE REST API credentials via your PayPal account. Login to https://developer.paypal.com/ >> My apps & credentials >> toggle "LIVE" >> create "App" >> fill required details >> you can able to access your LIVE REST API Credentials(Client ID & Secret). Guide link for REST API Credentials - https://developer.paypal.com/api/rest/#get-credentials Once you create LIVE REST API credentials (Client ID & Secret), please enter/pass the Client ID in your button code as below. Present button code implemented on your website, pointing to sandbox : <script src="https://www.paypal.com/sdk/js?client-id=sb¤cy=USD" data-sdk-integration-source="button-factory"></script> Pass the LIVE "Client_ID" as below to process payments in LIVE : <script src="https://www.paypal.com/sdk/js?client-id=Enter_the_Client_ID_value_here¤cy=USD" data-sdk-integration-source="button-factory"></script> I request to please use the updated button code on your website. I request to please process a test payments via card which is not linked to your PayPal account. Since, merchant can't process self payments. Thank you so much for your patience and understanding. Sincerely, Chiranjeevi PayPal/Braintree MTS If this post or any other was helpful, please enrich the community by giving kudos or accepting it as a solution.
