ExpandedToggleIcon        Connection Dialog

The following connection options are required:

1.Client Id - a GUID value, representing Marketo API client id;
2.Client Secret - Marketo API client secret;
3.Domain - Your Marketo subdomain;


To configure access to Marketo and get client id and client secret for the connection, see this instruction in Marketo documentation.


ExpandedToggleIcon        Advanced Connection Options

The following table describes the options that you can include in the Connection String using the Advanced Connection Editor dialog box:




Client Id

A GUID value, representing Marketo API client id.

Client Secret

Marketo API client secret.

Connection Lifetime

When a connection is returned to the pool, its creation time is compared with the current time, and the connection is destroyed if that time span (in seconds) exceeds the value specified by Connection Lifetime. The default value is 0 (connection always returns to pool).

Connection Timeout

The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error. The default value is 15.


Your Marketo subdomain.

Default Command Timeout

The time in seconds to wait while trying to execute a command before terminating the attempt and generating an error.

Failover Retries

The number of retry attempts to automatically re-run a command before displaying an error message in case when the command failed because of an error that may be temporary.


Request limit count. The maximum number of Marketo API requests, performed in a LimitWindow interval. Default value is 100, which corresponds to the default Marketo API call limit.


Request limit time window. The API call window (time interval), in seconds, within which the number of Marketo API requests is limited by the LimitCount parameter. Default value is 20 seconds, which corresponds to the default Marketo API call limit window.

Local SQL Engine

Determines whether to use local SQL engine for SELECT queries, that are too complex to translate them directly to Marketo API calls or to show an error message.

Max Pool Size

The maximum number of connections allowed in the pool. Setting the Max Pool Size value in the connection string can affect performance. The default value is 100.

Min Pool Size

The minimum number of connections allowed in the pool. The default value is 0.

Persist Security Info

Indicates if security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open state.


If true, by default, the connection is drawn from the appropriate pool or is created and added to the appropriate pool.

Proxy Host

The host name or IP address of proxy server.

Proxy Password

The password for the proxy server account.

Proxy Port

The port number of the proxy server. The default value is 3128.

Proxy User

The proxy server account name.


Indicates whether the connection is read-only (allows only SELECT statements).

Token Server

Not used for Marketo.


Determines whether to use Marketo Bulk Extract API for reading Marketo leads. In this case reading Marketo leads will use less API calls, but may take more time. Set to True only to read very large number of Marketo leads. Reading Marketo leads, created within a known period of time will improve reading performance, it's better to use "Created At" >= some value or/and "Created At" <= some value conditions in your query when using Marketo Bulk Extract API.

UTC Dates

If set to True, dates will be converted to UTC format during import, and the date values entered by the user (in SELECT statements, etc.) are considered UTC dates when sending them to the data source.
