## Example Usage
The following code snippet demonstrates how to use OFXGo to query and parse
OFX code from a checking account, printing the balance and returned transactions:
```go
client := ofxgo.Client{} # Accept the default Client settings
# These values are specific to your bank
var query ofxgo.Request
query.URL = "https://secu.example.com/ofx"
query.Signon.Org = ofxgo.String("SECU")
query.Signon.Fid = ofxgo.String("1234")
# Set your username/password
query.Signon.UserID = ofxgo.String("username")
query.Signon.UserPass = ofxgo.String("hunter2")
uid, _ := ofxgo.RandomUID() # Handle error in real code
query.Bank = append(query.bank, &ofxgo.StatementRequest{
TrnUID: *uid,
BankAcctFrom: ofxgo.BankAcct{
BankID: ofxgo.String("123456789"), # Possibly your routing number
AcctID: ofxgo.String("00011122233"), # Possibly your account number
AcctType: ofxgo.AcctTypeChecking,
},
Include: true, # Include transactions (instead of only balance information)
})
response, _ := client.Request(query) # Handle error in real code
# Was there an OFX error while processing our request?
if response.Signon.Status.Code != 0 {
meaning, _ := response.Signon.Status.CodeMeaning()
fmt.Printf("Nonzero signon status (%d: %s) with message: %s\n", response.Signon.Status.Code, meaning, response.Signon.Status.Message)
os.Exit(1)
}
if len(response.Bank) < 1 {
fmt.Println("No banking messages received")
os.Exit(1)
}
if stmt, ok := response.Bank[0].(*ofxgo.StatementResponse); ok {
fmt.Printf("Balance: %s %s (as of %s)\n", stmt.BalAmt, stmt.CurDef, stmt.DtAsOf)
fmt.Println("Transactions:")
for _, tran := range stmt.BankTranList.Transactions {
currency := defCurrency
if ok, _ := tran.Currency.Valid(); ok {
currency = tran.Currency.CurSym
}
fmt.Printf("%s %-15s %-11s %s%s%s\n", tran.DtPosted, tran.TrnAmt.String()+" "+currency.String(), tran.TrnType, tran.Name, tran.Payee.Name, tran.Memo)
}
}
```
## Requirements
OFXGo requires go >= 1.9
