Introduction

Pre-authorization, a fundamental concept in payment processing, allows businesses to reserve funds on a customer's payment method without immediately transferring the money. This method, often called manual capture, is particularly useful in scenarios where the final amount to be charged is uncertain at the time of authorization or when a service is to be confirmed before actual payment is taken.

In the context of Stripe Terminal, pre-authorization is implemented using the PaymentIntent API. By setting the capture method to "manual" as the PaymentIntent is created, you can ensure that the customer's card is authorized, but the funds remain held rather than being transferred instantly. This approach brings flexibility to you as a merchant by allowing you to capture the payment at a later time when you are ready to complete the transaction.

The following content provides not only an explanation of this process but also delivers an exact translation of the key details into Spanish. Additionally, this detailed discussion will include practical considerations, coordination requirements between the front-end and back-end systems, and comparisons to typical use cases. This comprehensive analysis aims to leave you with a deep understanding of pre-authorization with Terminal and a clear, accurate translation to help bridge language gaps.

Understanding Pre-Authorization and Manual Capture

Pre-authorization in payment processing revolves around the idea of placing a hold on funds. This mechanism entails verifying the availability of funds on the customer's card and reserving a specific amount. It does not result in an immediate withdrawal but simply earmarks the funds for future collection. The key advantage is that it reduces the risk of fraud and ensures that the funds will be available when the payment is eventually captured.

With Stripe Terminal, the pre-authorization process is simplified through the use of PaymentIntents. When setting up a PaymentIntent with a "manual" capture method, the system first authorizes the transaction; that is, it holds the funds but does not immediately charge the customer. Later, when conditions are met or the service is confirmed, the system finalizes or "captures" the PaymentIntent to collect the reserved funds.

The successful execution of such a process requires a well-coordinated system. Specifically, there must be clear communication and data synchronization between the user-facing application interface (front-end) and the back-end server. This ensures that the state of each PaymentIntent is tracked accurately through its lifecycle—from creation and authorization to final capture.

Critical Aspects of Pre-Authorization with Terminal

1. Authorization versus Capture

Pre-authorization separates the act of authorizing a transaction from the actual capture of funds. When you create a PaymentIntent with manual capture, the customer's card is authorized, ensuring that the funds are reserved. However, the capture, which transfers the funds, is deferred until a later, more appropriate time. This method provides both operational and financial flexibility.

2. Coordination between Front-End and Back-End

A smooth pre-authorization and later capture process requires well-designed integration between your application's front-end and the back-end. The front-end is responsible for initiating the PaymentIntent, while the back-end needs to handle the tracking and finalization of the PaymentIntent when the payment should actually be captured. Any delay or miscommunication can result in lost reservations or complications in transaction finalization.

3. Receipt Alternatives and Physical Printing

It is important to note that Stripe does not support physical printing options through Terminal. Instead, after a transaction is successfully performed, an email receipt can be sent to the customer's email provided during PaymentIntent creation (using the receipt_email parameter). This underscores the digital-first approach of modern payment systems.

4. Time Sensitivity and Card Brand Specifics

Pre-authorization windows may vary among different card brands. For instance, Visa may allow a specific time frame within which the capture must occur following the pre-authorization. Ensuring that you are aware of these windows helps in managing transactions effectively.

Practical Considerations in Implementing Pre-Authorization with Terminal

In addition to the translation, it is critical to comprehend the operational aspects and the technical requirements surrounding the use of pre-authorization in Stripe Terminal. Here are some practical insights:

Pre-Authorization Lifecycle

Initialization

The lifecycle begins when a PaymentIntent is created in the system. Here, by specifying the capture method as “manual”, the system authorizes the customer’s payment method, ensuring that a hold is placed on the funds but no immediate transfer occurs. This step is essential to confirm that the funds are available for future capture.

Handling the Authorization

During the authorization phase, a communication loop is established between the customer’s card network and Stripe’s servers. The financial institution then confirms that the funds are valid and reserves the necessary amount. Technically, this stage does not reflect a deduction from the customer’s account; instead, it only earmarks funds until the payment is captured.

Finalization and Capture

The process enters a critical phase when the merchant is ready to capture the funds. This typically happens once services are rendered or the final transaction details are confirmed. By finalizing the PaymentIntent, the hold is lifted and the funds are securely transferred from the cardholder’s account to the merchant’s account.

Backend and Frontend Coordination

A robust payment system needs seamless integration between the user interface and the server’s logic. Here are several aspects to consider:

State Tracking: The PaymentIntent’s status must be tracked accurately. Transitions, whether success or failure, need to be clearly signalled between the front-end and back-end systems to avoid discrepancies.
Error Handling: Any interruption during the authorization or capture stages should trigger error handling routines. Ensuring that the front-end can relay critical information to the user and the back-end can retry operations is crucial.
Security Protocols: Given the sensitive nature of financial transactions, all communications between the client’s application and the back-end server should employ robust encryption and comply with the required payment security standards.

Email Receipts and Customer Communication

While Stripe Terminal does not connect to any physical printing hardware, the alternative of sending an email receipt plays an important role in the customer experience. In the translation provided, it is noted that a receipt is dispatched only if a receipt_email parameter is included when creating the PaymentIntent. This reflects a digital workflow that is both agile and environmentally conscious. Additionally, email receipts serve as an audit trail and provide transparency for future disputes or transaction reviews.

Advanced Technical Considerations

For developers implementing pre-authorization, considering advanced technical aspects is vital to ensure robust functionality.

Handling Time-Sensitive Authorizations

One advanced aspect is the time sensitivity involved. Pre-authorizations can be subject to expiration if the capture does not occur within a set period defined by the card issuer. This can vary significantly between different card brands. For example, Visa may specify a five-day window for transactions initiated in person using Terminal. Monitoring these time frames programmatically can help avoid issues of a held transaction failing to capture in time.

Implementing scheduled tasks or leveraging webhooks to notify your application when a PaymentIntent is nearing expiry can be a valuable strategy. Such techniques ensure that your application can alert the merchant in a timely manner, offering the opportunity to capture funds before the authorization is voided.

Integration Testing and Debugging

Integration testing between the front-end and back-end is another crucial area. Test cases should simulate delayed captures, sudden cancellations, and network interruptions to verify that the system handles all scenarios gracefully. Developers should utilize sandbox environments provided by payment processors to confirm that both the authorization and capture behaviors are as expected. Clear logging and error reporting will significantly ease the debugging process when unexpected behavior occurs.

Alongside real-time monitoring, periodic audits of the PaymentIntent lifecycle can help ensure that the integration remains robust against any alterations in API behaviors or changes introduced in payment processing policies.

Final Thoughts

In summary, the process of implementing pre-authorization with Stripe Terminal is well-supported by modern payment frameworks. By leveraging PaymentIntent with manual capture, businesses can ensure that customer funds are safely authorized and reserved until the final moment of payment capture. The translation provided above in Spanish maintains all the technical details and nuances necessary for understanding the process, making it a valuable resource for Spanish-speaking developers and merchants.
