CData Cloud offers access to Act-On across several standard services and protocols, in a cloud-hosted solution. Any application that can connect to a MySQL or SQL Server database can connect to Act-On through CData Cloud.
CData Cloud allows you to standardize and configure connections to Act-On as though it were any other OData endpoint, or standard SQL Server/MySQL database.
This page provides a guide to Establishing a Connection to Act-On in CData Cloud, as well as information on the available resources, and a reference to the available connection properties.
Establishing a Connection shows how to authenticate to Act-On and configure any necessary connection properties to create a database in CData Cloud
Accessing data from Act-On through the available standard services and CData Cloud administration is documented in further details in the CData Cloud Documentation.
Connect to Act-On by selecting the corresponding icon in the Database tab. Required properties are listed under Settings. The Advanced tab lists connection properties that are not typically required.
Act-On uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties.
For authentication, the only difference between the two methods is that you must set two additional connection properties when using custom OAuth applications.
After setting the following connection properties, you are ready to connect:
When you connect, the Cloud opens the OAuth endpoint in your default browser. Log in and grant permissions to the application. The Cloud then completes the OAuth process as follows:
First, get an OAuthAccessToken by setting the following connection properties:
Then call stored procedures to complete the OAuth exchange:
After you have obtained the access and refresh tokens, you can connect to data and refresh the OAuth access token either automatically or manually.
Automatic Refresh of the OAuth Access Token
To have the driver automatically refresh the OAuth access token, set the following on the first data connection:
Manual Refresh of the OAuth Access Token
The only value needed to manually refresh the OAuth access token when connecting to data is the OAuth refresh token.
Use the RefreshOAuthAccessToken stored procedure to manually refresh the OAuthAccessToken after the ExpiresIn parameter value returned by GetOAuthAccessToken has elapsed, then set the following connection properties:
Then call RefreshOAuthAccessToken with OAuthRefreshToken set to the OAuth refresh token returned by GetOAuthAccessToken. After the new tokens have been retrieved, open a new connection by setting the OAuthAccessToken property to the value returned by RefreshOAuthAccessToken.
Finally, store the OAuth refresh token so that you can use it to manually refresh the OAuth access token after it has expired.
Option 1: Obtain and Exchange a Verifier Code
To obtain a verifier code, you must authenticate at the OAuth authorization URL.
Follow the steps below to authenticate from the machine with an internet browser and obtain the OAuthVerifier connection property.
On the headless machine, set the following connection properties to obtain the OAuth authentication values.
After the OAuth settings file is generated, you need to re-set the following properties to connect:
Option 2: Transfer OAuth Settings
Prior to connecting on a headless machine, you need to install and create a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.
After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.
After you have successfully tested the connection, copy the OAuth settings file to your headless machine.
On the headless machine, set the following connection properties to connect to data:
Authentication by password grant is similar to OAuth -- in fact, it requires that you have already set up a custom OAuth application, as described in Creating a Custom OAuth App -- but once it's set up it does not require user interaction.
To connect, set these properties:
You may choose to create your own OAuth Application Credentials when you want to
Follow the steps below to create a custom OAuth app and obtain the connection properties in a specific OAuth authentication flow.
Sign up to https://developer.act-on.com/provision/. After registering your account on Act-On you will get an email with the following connection properties:
The default value for the callback URL is http://localhost:80. If you would like to change it you need to contact the API support for Act-On.
By default, the Cloud attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.
To specify another certificate, see the SSLServerCert connection property.
To authenticate to an HTTP proxy, set the following:
Set the following properties:
The CData Cloud models entities in the Act-On API as tables, views, and stored procedures. These are defined in schema files, which are simple, text-based configuration files.
Lists in Act-On are exposed as views with the convention List_ListName. For each list there is another view List_ListName_Score where you can see the score
of the people in the list.
Same logic for Segments in Act-On, they are exposed as views as Segment_SegmentName. And have an equivalent view Segment_SegmentName_Score.
Any changes you make to your Act-On account, such as adding a new list, adding new columns, or changing the data type of a column, will immediately be reflected
when you connect using the driver.
The Cloud offloads as much of the SELECT statement processing as possible to the Act-On APIs and then processes the rest of the query within the Cloud. The following sections document API limitations and requirements.
Views are tables that cannot be modified. Typically, read-only data are shown as views.
Stored Procedures are function-like interfaces to the data source. They can be used to search, update, and modify information in the data source.
The Cloud models the data in Act-On as a list of tables in a relational database that can be queried using standard SQL statements.
| Name | Description |
| List_MyList | Create, update, delete, and query records of a List. |
| Optout | Upsert, delete and query records of a Optout list. |
Create, update, delete, and query records of a List.
Every list that is created in your Act-On account is represented by a new table that is dynamically retrieved from your Act-On account. The name of the table has the following format:
List_nameOfTheList
For example, if the list in the Act-On UI is called 'MyList', the name of the table in the driver would be 'List_MyList'.
This is an example on how a list is exposed as table.
Query records of the specified table.:
SELECT * FROM [List_MyList]
Create a new record in the table.
Note: The ListId is required to insert a new record into a table.
All the fields that are not read-only can be specified.
INSERT INTO [List_MyList] ([First Name], [Last Name], [E-mail Address], [ListId]) VALUES ('John', 'Doe', '[email protected]', 'l-000d')Update details of a specific record.
Note: To update a record from a table, the ListId and E-mail Address must be specified.

This section provides a complete list of the Miscellaneous properties you can configure in the connection string for this provider.
| Property | Description |
| MaxRows | Specifies the maximum rows returned for queries without aggregation or GROUP BY. |
| Pagesize | Specifies the maximum number of results to return from Act-On, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases. |
| PseudoColumns | Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property. |
| RowScanDepth | The maximum number of rows to scan to look for the columns available in a table. |
| Timeout | Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout. |
| TypeDetectionScheme | Determines how to determine the data type of columns. |
Specifies the maximum rows returned for queries without aggregation or GROUP BY.
int
-1
This property sets an upper limit on the number of rows the Cloud returns for queries that do not include aggregation or GROUP BY clauses. This limit ensures that queries do not return excessively large result sets by default.
When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting. If MaxRows is set to "-1", no row limit is enforced unless a LIMIT clause is explicitly included in the query.
This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.
Specifies the maximum number of results to return from Act-On, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases.
int
1000
You may want to adjust the default pagesize to optimize results for a particular object or service endpoint you are querying. Be aware that increasing the page size may improve performance, but it could also result in higher memory consumption per page.
Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.
string
""
This property allows you to define which pseudocolumns the Cloud exposes as table columns.
To specify individual pseudocolumns, use the following format: "Table1=Column1;Table1=Column2;Table2=Column3"
To include all pseudocolumns for all tables use: "*=*"
The maximum number of rows to scan to look for the columns available in a table.
int
50
The columns in a table must be determined by scanning table rows. This value determines the maximum number of rows that will be scanned.
Setting a high value may decrease performance. Setting a low value may prevent the data type from being determined properly, especially when there is null data.
Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.
int
60
This property controls the maximum time, in seconds, that the Cloud waits for an operation to complete before canceling it. If the timeout period expires before the operation finishes, the Cloud cancels the operation and throws an exception.
The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond 60 seconds if each paging call completes within the timeout limit.
Setting this property to 0 disables the timeout, allowing operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server. Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.
Determines how to determine the data type of columns.
string
"RowScan"
| None | Setting TypeDetectionScheme to None will return all columns as the string type. |
| RowScan | Setting TypeDetectionScheme to RowScan will scan rows to heuristically determine the data type. The RowScanDepth determines the number of rows to be scanned. |
