here is my code

async function tokenize(paymentMethod) {
        const verificationDetails = {
            amount: '1.00',
            billingContact: {
                givenName: 'John',
                familyName: 'Doe',
                email: '[email protected]',
                phone: '3214563987',
                addressLines: ['123 Main Street', 'Apartment 1'],
                city: 'London',
                state: 'LND',
                countryCode: 'GB',
            },
            currencyCode: 'GBP',
            intent: 'CHARGE',
            customerInitiated: true,
            sellerKeyedIn: false,
        };
        const tokenResult = await paymentMethod.tokenize(verificationDetails);
        if (tokenResult.status === 'OK') {
            return tokenResult.token;
        } else {
            let errorMessage = `Tokenization failed with status: ${tokenResult.status}`;
            if (tokenResult.errors) {
                errorMessage += ` and errors: ${JSON.stringify(
                tokenResult.errors,
            )}`;
            }
            throw new Error(errorMessage);
        }
    }

async function verifyBuyer(payments, token) {
        const verificationDetails = {
            amount: '1.00',
            billingContact: {
                givenName: 'John',
                familyName: 'Doe',
                email: '[email protected]',

            },
            currencyCode: 'GBP',
            intent: 'CHARGE',
            customerInitiated: true,
            sellerKeyedIn: false,
        };
        console.log(verificationDetails);
        console.log(token);
        const verificationResults = await payments.verifyBuyer(
            token,
            verificationDetails
        );

The error messages you’re seeing typically indicate that some required parameters are missing or incorrectly formatted in your requests.

For the first error in paymentMethod.tokenize(verificationDetails), ensure that the verificationDetails object is correctly formed and includes all necessary fields. This object should encapsulate the following information:

  • intent: The buyer’s intended action, such as ‘STORE’ or ‘CHARGE’.
  • locationId: The location IDs found on the Locations page for your application in the Developer Dashboard.
  • amount: The total amount of the payment.
  • currencyCode: The currency code of the payment.

For the second error in payments.verifyBuyer(token, verificationDetails), make sure that both the token and verificationDetails are correctly provided. The token should be the payment token returned by the CardEntry activity or a card-on-file ID for the buyer’s payment card stored with Square. The verificationDetails should be the same as described above.

If you’ve checked these and the issue persists, it might be helpful to double-check that your dependencies and SDK versions are up to date, as outdated versions can sometimes cause unexpected errors.

there is no place in docs indicates that we put locationId in verificationDetails, but it worked when i put it while initializing payments object it wasn’t required at first to put locationId and it was working but apperently you need it for the new flow
