Verify Transaction

You can verify transaction by passing or tx-ref, PaymentType object to ChapaUtil.verifyTransaction() method

If you don't initialize ChapaConfiguration, use can verify transaction using your tx-ref and chapa-public-key

ChapaUtil.verifyTransaction("tx-ref", new ChapaVerifyTransactionCallback() {
    @Override
    public void onResult(boolean verified, @Nullable Transaction transaction) {
        if (verified) {
            // payment is verified
        } else {
            // payment is not verified
        }
    }

    @Override
    public void onError(ChapaError error) {
        // Error occurred in verifying transaction
        // TODO your code here
    }
});

ChapaUtil.verifyTransaction("tx_ref", object : ChapaVerifyTransactionCallback {
/**
 * verify transaction
 *
 * @param verified    true if transaction is verified otherwise false
 * @param transaction if verified [Transaction] otherwise null
 */
 override fun onResult(verified: Boolean, transaction: Transaction?) {
    if (verified) {
        // payment is verified
    } else {
        // payment is not verified
    }
 }

 override fun onError(error: ChapaError?) {
    // Error occurred in verifying transaction
    // TODO your code here
 }
})
