I’m using the sample invoices provided in the SDK within my Laravel project.  
I’ve made some modifications to them.

When testing six invoices — three **Standard** and three **Simplified** — the **Standard invoices** are passing successfully, but **all three Simplified invoices are failing**.

Here are the error messages I’m getting:

> **implified** —

make sure  
Before checking the compliance  
Take the returned SecurityBinaryToken returned from First API and decode it using base64 decoder, the decoded value is the x.509 certificate

go to the SDK folder to the following path: SDK/Data/Certificates/Cert.pem

replace the generated private key with the value in the other file in the same path: SDK/Data/Certificates

and then perform  
fatoora -sign -invoice Simplified\_Invoice.xml  
fatoora -sign -invoice Simplified\_Credit\_Note.xml

fatoora -sign -invoice Simplified\_Debit\_Note.xml

while passing the invoice to compliance API  
make sure you use the Simplified\_Invoice\_signed.xml Simplified\_Credit\_Note\_signed and Simplified\_Debit\_Note\_singed XML value converted to base64
