🔗 Integration with SAT.ws using Python and FastAPI
SAT.ws is a cloud API that connects directly to the Mexican Tax Administration Service (SAT), allowing you to automate the extraction of electronic invoices (CFDIs) without the need for manual access.
⚙️ Asynchronous Process
The process is asynchronous: first, you make an initial request to SAT.ws to extract the invoices. The platform processes this request in the background and does not immediately deliver the invoices. To avoid repetitive queries about the status of the process, webhooks can be used. By registering a webhook URL on SAT.ws, you will receive an automatic notification when the invoices are ready to be downloaded.
📥 Final Request for Invoices
Once this notification is received, your application can make a second request to finally obtain the files (XML and PDF).
🚀 Benefits of FastAPI
FastAPI is especially useful in this context, as it facilitates the handling of asynchronous operations between the SAT and your application. Its SWAGGER integration is very helpful and simplifies the configuration of endpoints to receive notifications via webhook. This integration makes the entire process efficient and easy to implement.
