Configuration

Now, It's time to see, how we can authenticate using our credentials.

To create a new FIB client, simply use the New function with your clientID and clientSecret. The third argument specifies whether you are using the testing environment (true for testing, false for production).

Here is an example to create a client, under the hood it authenticates and returns access token:

clientID := "your-client-id"
clientSecret := "your-client-secret"
 
// is it testing environment or production environment
isTesting := false
 
client, err := fib.New(clientID, clientSecret, isTesting)
if err != nil {
    log.Fatalf("Error creating FIB client: %s - %s", err.Title, err.Description)
}

Error handling

The New function returns an error of type *LoginError if the client creation fails. This custom error type provides more context about what went wrong during the initialization.

The LoginError struct contains two fields:

Title: A short description of the error.
Description: A more detailed explanation of the error.

type LoginError struct {
	Title       string
	Description string
}
