Use credit card token rest api paypal

Question

I'm trying to use payment Vault from paypal payment. I'm following this https://developer.paypal.com/docs/integration/direct/vault/#store-credit-card

I call: https://api.sandbox.paypal.com/v1/payments/payment

{
  "id":"CPPAY-13U4fds67758H032001PKPIFQZI",
  "intent":"sale",
  "payer":{
  "payment_method": "credit_card",
  "funding_instruments":[
      {
        "credit_card_token":{
        "credit_card_id":"CARD-3S3021595U985430TLCM4HLA"
        }
     }
]
},
"transactions": [
    {
      "amount":
      {
        "total": "1.00",
        "currency": "USD"
      },
      "description": "Testando pagamento cartao Vault."
    }]
}

But I'm getting this message:

{
  "name": "UNKNOWN_ERROR",
  "message": "An unknown error occurred.",
  "information_link": "https://developer.paypal.com/webapps/developer/docs/api/#UNKNOWN_ERROR",
  "debug_id": "64f99d6ec2b1f"
}

Okay that means you sending directly with URL so you are doing something wrong with API,username password and signature — Tejas Mehta
No, the credentials were all right. I did another vault with another card number and it worked — Midori Fukami

First check CardID validity. Is that card id expired or still valid.

If valid then You have Card ID like this "CARD-1E9132746P400060DLCNN6WY"

And pass that Card ID to Credit card token.

$creditCardToken = new CreditCardToken();
$creditCardToken->setCreditCardId($credit_card_id);
$fi = new FundingInstrument();
$fi->setCreditCardToken($creditCardToken);
$payer = new Payer(); 
$payer->setPaymentMethod("credit_card");
$payer->setFundingInstruments(array($fi));

I think your error is due to last line of my above code Please cast funding instrument object with array and you will get your error solved. Change your code as below

$payer->setFundingInstruments(array($fi));
