    </OAuthV2>

In the demonstrated example, all essential components are incorporated and appropriately implemented. ### Unsuccessful Authentication Failure in authentication may occur if the client software fails to validate its identity to the Apigee API system. This can result from wrong client identification, expired passkeys, or client software unregistered with Apigee. As a corrective measure, affirm the client identification details, ensuring their correctness. Keep a tab on the passkey expiry window and rejuvenate the passkey if required. If the client software is unregistered with Apigee, register it and give it another go. ### Authorization Denials Authorization denial can happen when the client software lacks permission to fetch the sought-after resource. This might be due to the software lacking access rights or the specific resource being guarded by an API security protocol. For rectification, inspect the rights of the client software and affirm its access to the requested resources. If the resource is guarded by a safety protocol, verify that the protocol is appropriately configured and the client software holds the rights to access the resource. ### Quota Breach Errors Errors due to overflowing the quota emerge when the client software surpasses the assigned number of API requests within a specified timeframe. This is controlled by the Quota protocol in Apigee. For addressing this, examine the Quota protocol setup and ensure it's rightly configured. If the client software is exceeding the quota, ponder on augmenting the quota or incorporating a throttling mechanism.

<Quota name="Quota">
        <Interval>1</Interval>
        <TimeUnit>minute</TimeUnit>
        <Allow count="100"/>
        <Distributed>true</Distributed>
        <Synchronous>true</Synchronous>
    </Quota>
