In Salesforce Marketing Cloud, access tokens are valid for one hour (D). After one hour, a new access token must be obtained to continue making API calls. This ensures security and helps manage the lifespan of tokens effectively.

To convert a string payload in JSON format to a JavaScript object on a CloudPage, the developer should use the ParseJSON (B) function in Marketing Cloud Server-Side JavaScript (SSJS). This function parses a JSON string and returns a corresponding JavaScript object.

Example:

var jsonString = '{"key1":"value1", "key2":"value2"}'; var jsonObject = Platform.Function.ParseJSON(jsonString);

The Contact Delete process can be slow for a large number of contacts. To expedite this process, the best approach is to stop the current delete process and delete smaller groups of contacts. This allows the system to handle smaller chunks of data more efficiently.

Stop Current Process: Stopping the current large delete process helps avoid system overload and potential timeouts.

Delete in Smaller Groups: By segmenting the contacts into smaller groups and deleting them in batches, the process becomes more manageable and faster.

To configure a data extension to store data for six months, you should update the data extension configuration to include data retention settings.

Data Retention Settings: You can configure data retention directly within the data extension settings in Email Studio to specify how long data should be retained. This ensures that data older than the specified period is automatically deleted.

Go to Email Studio -> Subscribers -> Data Extensions.

Select the data extension you want to configure.

Click on "Properties".

Under "Data Retention", set the retention period to six months and define the retention settings accordingly.

In Marketing Cloud, the Contact Key should be represented as a Text data type, even if it is a numeric value. This is because using the Text data type avoids issues related to numeric value formatting and allows for greater flexibility in handling the values.

Salesforce Contact Builder Best Practices

To create a query that aggregates clicks grouped by the language of the recipient, the developer needs to use Data Views that store subscriber and click information. The required Data Views are:

_Subscribers (A) - This Data View contains information about subscribers, including their profile attributes such as language.

_Click (D) - This Data View contains information about click events for email messages, which can be used to aggregate clicks.

The query would join these Data Views on a common identifier (e.g., SubscriberKey) and group the results by the language attribute.

To programmatically inject Contacts into a journey via the REST API, the recommended route is /interaction/v1/events. This endpoint allows you to trigger an event which can be configured to start a journey for the specified contacts.

The newly created data model in Contact Builder can be used for segmentation in the following applications:

Email Studio (A) - Email Studio can use data extensions and attribute groups from Contact Builder for segmentation.

Journey Builder (C) - Journey Builder can leverage the data model created in Contact Builder for creating targeted journeys and audience segments.

To ensure that contacts relate across different channels in Marketing Cloud, you need to link the unique identifier used across channels to the Contact ID in Contact Builder. This involves creating Attribute Groups and establishing the relationships between the unique identifier and the Contact ID.

Link the Numeric Field Value: By linking the numeric unique identifier to the Contact ID in Attribute Groups, you ensure that each contact is uniquely identified across channels.

Create Attribute Groups: Attribute Groups in Contact Builder allow you to map the relationships between different data sources and the Contact object, ensuring that the unique identifier is connected correctly for each channel.
