2 – Access Credentials: Get your test user so you can start your integration.

At SW®, we understand how important it is for you to test your system and ensure its security before launching it in the production environment. That’s why we provide a testing environment for all our services.

Steps to follow:

The testing environment has special access credentials: Request test environment credentials
Get to know our ⚒Test URL: https://services.test.sw.com.mx
Identify and use our special test CSDs. Be careful not to confuse CSDs with FIEL or E. FIRMA.

💡

TIP: You can use real RFCs in this environment, but we recommend using test RFCs.

3 – Authentication: The first steps

This is the first step, where with your credentials you will carry out the authentication process with which you will obtain a token that will allow you to consume all our services.

There are two ways to obtain the token:

API Token

Obtain a temporary token with a 3-hour validity period through our API.

Infinite Token

Obtain an infinite token that will allow you to consume services without having to generate it for each request or every certain period of time

💡

TIP: Each environment has its own credentials, so it is important not to mix them up to avoid mistakes.

4 – Types of stamping: Learn about our stamping options

We strive to offer you the greatest convenience in your processes, which is why we offer different stamping options. We offer options where you can seal and stamp, or simply stamp, depending on your current process.

📄 Is ‘Timbrar’ the same as ‘Sellar’ a CFDI?

No, ‘Sellar’ a CFDI refers to signing the document with our Digital Stamp Certificate (CSD), so that the authenticity of the document can be verified. To seal the CFDI, the values of important attributes for the SAT are concatenated, representing our original chain.

On the other hand, ‘Timbrar’ refers to generating and placing a Digital Fiscal Stamp that validates a Digital Fiscal Receipt over the Internet. This fiscal stamp is obtained by connecting to an Authorized Certification Provider (PAC) over the internet.

📄 Where can I see the structure of XML and JSON?

We understand that having an example can be very useful for the stamping process. We’ve created an examples section where you can see the different CFDI forms and their complements in both XML and JSON formats.

See the examples here: Examples
