How to use it

Opening the private key file.

privateKey, err := os.ReadFile("private.prv")
if err != nil {
    panic(err)
}

Then create an instance of the Moadian interface and pass the information.

var moadian service.Moadian
baseInfo := service.MoadiInfoStruct{
    FiscalID: "Your Fiscal id",
    PrivateKey: privateKey,
    TaxServerPublicKey: "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",

}
moadian = &baseInfo

Get the token and pass the token and a map of invoice data to SendInvoice method.

tokenResData, err := moadian.GetToken()

    panic(err)
}

sendInvoiceResData, err := moadian.SendInvoice(
    &token,
    &packetData,

if err != nil {
    panic(err)

refNumber := sendInvoiceResData.Result[0].ReferenceNumber

And you can also inquiry the invoice by ReferenceNumber

refNumbers := []string{refNumber}
inquiryResData, err := moadian.InquiryByReferenceNumber(&token, &refNumbers)
if err != nil {
    panic(err)
}
fmt.Println(inquiryResData.Result.Data[0].Status)
fmt.Println(inquiryResData.Result.Data[0].Data.Error)
fmt.Println(inquiryResData.Result.Data[0].Data.Warning)
