Fine-Tuning Data Access
You can use the following properties to gain more control over the data returned from Zoho Books:
- OrganizationId: The Id associated with the specific Zoho Books organization you wish to connect to. In Zoho Books, your business is termed as an organization. If you have multiple businesses, you simply set each of those up as an individual organization. Each organization is an independent Zoho Books Organization with its own organization ID, base currency, time zone, language, contacts, reports, etc. If the value of Organization Id is not specified in the connection string, then we will make a call to get all the available organizations and will select the first organization Id as the default one.
- AccountsServer: The full Account Server URL. Most of the time, the value of this property will be https://books.zoho.com, but if your account resides in a different location, then the domain should change accordingly (.eu, .in, .com.au, ...).
Customizing the SSL Configuration
By default, the connector attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store. To specify another certificate, see the SSLServerCert property for the available formats to do so.
Connecting Through a Firewall or Proxy
To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.
In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.
Set the following properties:
- To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
- To tunnel the connection, set FirewallType to TUNNEL.
- To authenticate, specify FirewallUser and FirewallPassword.
- To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.
Troubleshooting the Connection
To show connector activity from query execution to network traffic, use Logfile and Verbosity. The examples of common connection errors below show how to use these properties to get more context. Contact the support team for help tracing the source of an error or circumventing a performance issue.
- Authentication errors: Typically, recording a Logfile at Verbosity 4 is necessary to get full details on an authentication error.
- Queries time out: A server that takes too long to respond will exceed the connector's client-side timeout. Often, setting the Timeout property to a higher value will avoid a connection error. Another option is to disable the timeout by setting the property to 0. Setting Verbosity to 2 will show where the time is being spent.
- The certificate presented by the server cannot be validated: This error indicates that the connector cannot validate the server's certificate through the chain of trust. If you are using a self-signed certificate, there is only one certificate in the chain.
To resolve this error, you must verify yourself that the certificate can be trusted and specify to the connector that you trust the certificate. One way you can specify that you trust a certificate is to add the certificate to the trusted system store; another is to set SSLServerCert.
