A New Era for the OpenPix Webhook System: Optimized Efficiency and Resiliency


Webhook is one of the essential components for successful instant payments. Through Webhooks, merchants can be informed, in real time, of the status of their transactions, without having to question the payment system's server about the progress of their transactions.

Webhooks allowed immediate responses to the final consumer, by updating when the transaction was paid, allowing the merchant to complete the sale faster. This real-time experience is essential for retail and digital platforms as it allows orders to be released or delivered.

Webhook is part of the Pix revolution, being one of the essential components of the Pix experience, as it allows Pix to be used in a cashier, ecommerce checkout and even via text messages.

The success of the webhook and its importance for retail have made this component mission critical. Webhooks cannot lag or fail. And even if they fail or take a long time, the servers must be resilient and independent to re-send the payment confirmation until the merchant's servers confirm receipt.

Before the advent of the webhook, payment systems used polling methods via API to try, albeit via brute force, to find out as quickly as possible whether a transaction was paid or not. The challenge of pooling is that it is up to the client's server to keep questioning the payment server, on a recurring basis, until it gets a response and success, which is not fast and with the aggravating factor of being extremely inefficient and costly. And even in aggressive pooling of a few minutes it is impossible to predict when a transaction will be paid.


OpenPix stands out as a pioneer in offering robust solutions to deliver the best experience in triggering efficient webhooks code for the Pix environment. Every day OpenPix processes millions of webhooks notifying our customers and platforms in real time that transactions have been paid. This is not an easy task, considering that for each webhook we have to coordinate the customer's balance with the more than 900 banks that make up the Pix network. The OpenPix Webhook is one of the most robust on the market.

We are proud to announce new advancements in our webhook system, which will adopt a new standard of excellence in the industry. As of now, we are introducing an SLA for delivering webhooks for our customers with sub-second times, or for those who like data: SLA for delivery in the 750ms range (just over half a second). This is an extremely aggressive goal, and comes close to the physical limits that servers can reach.

Our team of engineers, in a continuous effort of innovation and improvement, revisited the entire code of our webhooks system. The result of this collaborative and intensive effort was a optimization in the speed and resiliency of our webhooks. This impressive increase in speed not only improves the efficiency of transactions, but also provides our customers with a more efficient and faster experience.

Furthermore, we know that our customers depend on us for the security and reliability of their transactions. That's why we are proud to announce that, in addition to optimizing the speed of webhooks, we also we have increased the resilience and guarantee of shots. Currently, our webhooks boast an incredible SLA of 99.99%. This means you can trust OpenPix to process your transactions consistently.


The implemented improvements are a strong commitment by OpenPix to provide our customers with the best possible Pix environment. We recognize the importance of efficiency and reliability in the digital economy. That's why we are constantly looking for ways to improve our systems and ensure that our customers have the best possible experience.

The other webhook functionalities were also expanded: Platform clients continue to support existing features such as: Multiple webhooks per company, multiple webhooks per account, webhook for REST API.

These significant advances are just the beginning. At OpenPix, we see each improvement as a stepping stone to the next innovation. We are excited about what the future holds and will continue to work tirelessly to bring the best products and services to our customers.
