This publicily available API provided by Card2Crypto.org allows you to generate payment links anonymously without KYC. You can accept Global Credit/debit card (including MasterCard, Visa, and Maestro) – Apple Pay – Google Pay – SEPA or ACH local bank transfer. You will receive instant payouts to your USDC (Polygon) wallet address once the customer pay using the link. For more information visit: https//Card2Crypto.org
\nFor successful payment link generation, you need to make two mandatory steps:
\nGenerate a temporary encrypted wallet address using GET https://api.card2crypto.org/control/wallet.php by passing a unique callback URL + your own USDC (Polygon) wallet address to receive payouts. Optionally you can use the affiliate.php wallet creator and pass an additional wallet you own to earn affiliate percentage commission on every sale.
Redirect the customer to the payment page by passing the generated encrypted wallet address along with other required parameters through another GET request to https://pay.card2crypto.org/process-payment.php This rquest will directly send the customer to the payment page.
Please consult minimum order values for payment providers.

The request includes the wallet address and a callback URL. The response returns a status code of 200, along with the encrypted receiving wallet address and callback URL in the JSON format.
\naddress: The wallet address to receive instant payouts after customer payment. Wallet must be a valid USDC (Polygon).
callback: urlencoded callback URL where the payment confirmation will be sent using GET request. You must have at least one unique GET parameter with each request. If you use the same parameter value again the same temporary receiving address will be provided in the response.
The response returns a newly generated encrypted receiving temporary wallet address and the same provided callback URL for confirmation in the JSON format. You may need to json_decode(); the response address_in to pass it in the next step.
address_in : This is the encrypted wallet address that need to be passed to the payment link generator (Process Payment) in the second step.
polygon_address_in : This is the generated receiving address decrypted for easy payment tracking. You can't pass this address directly to the second step, you need to pass the encrypted address_in.
callback_url : This is the same callback URL you passed containing all your parameters returned in a decoded format for confirmation. Our bot will send a GET request to this URL when the customer complete the payment containing all your parameters with an additional parameter value_coin representing the actual USDC value sent by the payment provider which can be useful for your system in case you want to verify the sent amount.
