PayPal REST API - 结算协议不会返回令牌

Question

我尝试使用REST API创建PayPal定期订阅（信用卡）：

制定结算方案 - https://developer.paypal.com/docs/api/quickstart/create-billing-plan/

制定帐单协议 - https://developer.paypal.com/docs/api/quickstart/create-billing-agreement/

我正在测试和使用API​​，所以我创建了两个文件plan.php和agreement.php。

plan.php 是我生成计划ID并在 agreement.php 中静态传递的地方。

plan.php 的

<?php

require 'vendor/autoload.php';

$apiContext = new \PayPal\Rest\ApiContext(
  new \PayPal\Auth\OAuthTokenCredential(
    'Application-ID',    
    'Secret-ID'  
  )
);

use PayPal\Api\ChargeModel;
use PayPal\Api\Currency;
use PayPal\Api\MerchantPreferences;
use PayPal\Api\PaymentDefinition;
use PayPal\Api\Plan;
use PayPal\Api\Patch;
use PayPal\Api\PatchRequest;
use PayPal\Common\PayPalModel;

use PayPal\Api\Agreement;
use PayPal\Api\Payer;
use PayPal\Api\ShippingAddress;
use PayPal\Api\CreditCard;
use PayPal\Api\FundingInstrument;

    $plan = new Plan();
    $plan->setName('T-Shirt of the Month Club Plan')
      ->setDescription('Template creation.')
      ->setType('fixed');

    // Set billing plan definitions
    $paymentDefinition = new PaymentDefinition();
    $paymentDefinition->setName('Regular Payments')
      ->setType('REGULAR')
      ->setFrequency('Month')
      ->setFrequencyInterval('2')
      ->setCycles('12')
      ->setAmount(new Currency(array('value' => 100, 'currency' => 'USD')));

// Set charge models
$chargeModel = new ChargeModel();
$chargeModel->setType('SHIPPING')
  ->setAmount(new Currency(array('value' => 10, 'currency' => 'USD')));
$paymentDefinition->setChargeModels(array($chargeModel));

// Set merchant preferences
$merchantPreferences = new MerchantPreferences();
$merchantPreferences->setReturnUrl('http://localhost:3000/processagreement')
  ->setCancelUrl('http://localhost:3000/cancel')
  ->setAutoBillAmount('yes')
  ->setInitialFailAmountAction('CONTINUE')
  ->setMaxFailAttempts('0')
  ->setSetupFee(new Currency(array('value' => 1, 'currency' => 'USD')));

$plan->setPaymentDefinitions(array($paymentDefinition));
$plan->setMerchantPreferences($merchantPreferences);




//create plan
try {
  $createdPlan = $plan->create($apiContext);

  try {
    $patch = new Patch();
    $value = new PayPalModel('{"state":"ACTIVE"}');
    $patch->setOp('replace')
      ->setPath('/')
      ->setValue($value);
    $patchRequest = new PatchRequest();
    $patchRequest->addPatch($patch);
    $createdPlan->update($patchRequest, $apiContext);
    $plan = Plan::get($createdPlan->getId(), $apiContext);

    // Output plan id
    echo $plan->getId();
  } catch (PayPal\Exception\PayPalConnectionException $ex) {
    echo $ex->getCode();
    echo $ex->getData();
    die($ex);
  } catch (Exception $ex) {
    die($ex);
  }
} catch (PayPal\Exception\PayPalConnectionException $ex) {

然而，它没有返回令牌，并且未设置成功变量。我打印了 $ agreement 变量，下面是回复：

为什么我无法获得令牌？

提前致谢。

Answer 1

这是您的解决方案

1）创建计划时，您需要将返回网址设为Execute.php。

2）您将该计划ID传递给了结算协议

3）您的agreement.php print_r（$ agreement-＆gt; toArray（））;

4）买方批准协议时，它会重定向到Execute.php，即创建计划时返回的Url集。

5）在execute.php中，您将获得令牌并成功为真。

您正在添加执行协议的代码 协议创造。这就是你没有获得成功的原因， 您可以在买方批准后按ID执行结算协议。 检查以下链接。

https://developer.paypal.com/docs/api/payments.billing-agreements

所以现在你应该从agreement.php中删除执行代码并添加execute.php 用这个

<?php

// #Execute Agreement
// This is the second part of CreateAgreement Sample.
// Use this call to execute an agreement after the buyer approves it
require __DIR__ . '/../bootstrap.php';

// ## Approval Status
// Determine if the user accepted or denied the request
if (isset($_GET['success']) && $_GET['success'] == 'true') {
    $token = $_GET['token'];
    $agreement = new \PayPal\Api\Agreement();
    try {
        // ## Execute Agreement
        // Execute the agreement by passing in the token
        $agreement->execute($token, $apiContext);
    } catch (Exception $ex) {
        // NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY
        ResultPrinter::printError("Executed an Agreement", "Agreement", $agreement->getId(), $_GET['token'], $ex);
        exit(1);
    }

    // NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY
    ResultPrinter::printResult("Executed an Agreement", "Agreement", $agreement->getId(), $_GET['token'], $agreement);

    // ## Get Agreement
    // Make a get call to retrieve the executed agreement details
    try {
        $agreement = \PayPal\Api\Agreement::get($agreement->getId(), $apiContext);
    } catch (Exception $ex) {
        // NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY
        ResultPrinter::printError("Get Agreement", "Agreement", null, null, $ex);
        exit(1);
    }

    // NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY
    ResultPrinter::printResult("Get Agreement", "Agreement", $agreement->getId(), null, $agreement);
} else {
    // NOTE: PLEASE DO NOT USE RESULTPRINTER CLASS IN YOUR ORIGINAL CODE. FOR SAMPLE ONLY
    ResultPrinter::printResult("User Cancelled the Approval", null);
}
