FAQ

API FAQs

Do I need to generate XML, seals, or original chains?
It depends on your stamping method. With the JSON method (the most popular), you do NOT need any of that — you send the data and we handle everything. If you already generate your own sealed XML, you can send it via XML Base64 or XML Multipart and we simply stamp it.
Does the API have an additional cost?
No, the stamping API is included at no additional cost with all stamp packages. All 3 stamping methods are available. You only consume one stamp (credit) per successfully generated CFDI.
How long does it take to stamp a CFDI?
The average stamping time is under 100 milliseconds. Our AWS infrastructure with load balancers and multiple PACs ensures high availability and speed.
Can I test the API for free?
Yes, we have a completely free sandbox environment at sandbox-app.facturadigital.com.mx with 10 test stamps. The sandbox replicates the production environment exactly, including all 3 stamping methods.
What programming languages can I use with the API?
Our API is REST over HTTPS and communicates with JSON, so you can integrate it with any programming language: PHP, Python, Java, C#, Node.js, Go, Ruby, Swift, Kotlin, and any other language that supports HTTP requests.
Can I migrate from another PAC without modifying my code?
Yes. If you already generate your sealed XML, you can send it as-is through our XML Base64 or XML Multipart methods. Just change the endpoint URL and authentication — no need to modify your XML generator.
Can I stamp Carta Porte and Payroll complements via API?
Yes, the API supports all CFDI types and all current complements: Carta Porte 3.1, Payments 2.0 Rev. B, Payroll 1.2 Rev. E, Foreign Trade 2.0, Charitable Donations, IEDU, INE, Airlines, Retail, Local Taxes, Hydrocarbons, and more.
