Use Webhooks for Real-Time Updates
Webhooks are the optimal way to receive real-time notifications, offering a faster, more efficient solution that saves time and reduces operational complexity for our clients. By using webhooks, you ensure immediate updates without delays, helping your system stay responsive and synchronized.
While we strongly recommend webhooks for the best performance, we understand that some setups might still rely on polling. If necessary, you can use polling by sending a request to the POST endpoint and later fetching the response from the corresponding GET endpoint. Please note, however, that excessive polling can increase system load and lead to inefficiencies, potentially affecting the processing of transactions.
Embrace webhooks to simplify your workflow and enhance system performance.
