title: Paypal billing agreement does not pay quickly?
body: <p>I've made a Paypal plan like the following, at 49$ :</p>
  
  <pre><code>{
      'id': 'P-PAYPAL-ID',
      'name': "My Plan",
      'description': 'My description of the plan',
      'type': 'INFINITE',
      'merchant_preferences': {
          'auto_bill_amount': 'YES',
          "initial_fail_amount_action": "CONTINUE",
          "max_fail_attempts": "3",
          "return_url": "https://example.com/paypal/response",
          "cancel_url": "https://example.com/paypal/response"
      },
      'payment_definitions': [{
          'name': 'Monthly payment',
          'type': 'REGULAR',
          'frequency': 'MONTH',
          'frequency_interval': 1,
          'cycles': 0,
          'amount': {
              'value': '49',
              'currency': 'USD'
          }
      }]
  }
  </code></pre>
  
  <p>I've created the plan and enabled it following the <a href="https://developer.paypal.com/docs/api/payments.billing-plans/#plan_create" rel="nofollow">documentation here</a>.</p>
  
  <p>Then I created a <a href="https://developer.paypal.com/docs/api/payments.billing-agreements" rel="nofollow">Billing Agreement</a> by following the steps :</p>
  
  <ol>
  <li>Create the billing agreement</li>
  <li>Redirect the user to the Paypal page to accept the agreement</li>
  <li>Execute the agreement from the URL I got in 1.</li>
  </ol>
  
  <p>Everything works fine, in my sandbox user account, I can see the "Recurring payment details" marked as Active.</p>
  
  <p>I subscribed my server to the webhooks.</p>
  
  <p><strong>My problem is the following</strong> : The payment is not done immediately? I've waited an hour, and nothing is paid!</p>
  
  <p>Is there a request I forgot to make to "execute the executed agreement"...?</p>
