To connect to MYOB, you can use either a DSN or an ODBC connection string. Both of these methods use the Database's Open method.

Connect to a DSN

To connect using a DSN:

var db = new Database();
db.open("DSN=CData MYOB Sys", (err) => {
    // Use the connection
});

Provide a Driver Connection String

To connect using an ODBC connection string:

var db = new Database();
db.open("DRIVER={CData ODBC Driver for MYOB}; If using an online instance: OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;CompanyFileId=yourCompanyFileId;CallbackURL=http://localhost:33333;User=companyFileUser;Password=companyFilePassword; If using an on premise instance: InitiateOAuth=OFF;URL=http://localhost:8080/accountright;CompanyFileId=327eed10-9615-4e5e-bd9e-ae2cc00e2c70;User=companyFileUser;Password=companyFilePassword;;", (err) => {
    // Use the connection
});
