To add new customers to a cross-channel welcome campaign when they register on the company website, the Journey Builder API (D) should be used. This API allows you to programmatically inject contacts into a journey, triggering personalized marketing interactions across multiple channels.

To add records to a Data Extension using the SOAP API, the DataExtensionObject object is utilized. This object represents a row within a data extension.

DataExtensionObject: This object is specifically designed to interact with data extensions, allowing you to insert, update, and retrieve rows. Here is a basic example of how to use this object to add a record:

DataExtensionExternalKey SubscriberKey example@example.com FirstName John LastName Doe

To securely pass parameters between CloudPages without exposing them, use the CloudPagesURL function within a form action. This method encodes the parameters and securely posts them to the target CloudPage.

CloudPagesURL: Encodes and includes parameters securely.

Form Method: Using the post method ensures parameters are sent in the request body, adding another layer of security.

Salesforce CloudPagesURL Function

To add and verify From Addresses in Marketing Cloud, you can use the following routes:

QUESTIONNO: 111

Northern Trail Outfitters sends a weekly email with dynamic content, and they want to record custom data inside a send log on each send to record what content was displayed and correlation flags.

What is the maximum number of custom data points recommended by Salesforce to ensure sends speeds are not affected when inserting into the built-in send log?

A. 20 fields or less

B. 10 fields or less

C. No limit

D. 5 fields or less

Answer: C

Profile attributes like AGE in Profile Manager are not directly accessible via the _Subscribers data view or _EnterpriseAttribute data view. To retrieve subscribers over 30 years of age, creating a filtered Group based on the AGE attribute is the most effective method.

Salesforce Subscriber Filters and Groups

The purpose of the IF statement in the AMPscript code is to check if any rows are returned by the LookupRows function. If rows are returned, it retrieves the image field from the data extension and sets the image source accordingly. If no rows are returned, it defaults to using a standard image.

Salesforce AMPscript LookupRows Function

To validate an email address prior to form submission, the REST API endpoint /address/v1/validateEmail can be used. This endpoint allows you to check if the email address is formatted correctly and potentially validate it against known email address patterns.

Salesforce REST API for Email Validation

To manage the data model programmatically and access the Attribute Group schema, the REST API should be used. The REST API provides endpoints to interact with and retrieve information about Attribute Groups and their schemas.

Salesforce REST API

To configure a File Drop Automation with a filename pattern that allows for timestamps and starts with the month and day, the developer should use:

Begins With operator (D) - This ensures that the automation triggers when the file name begins with the specified pattern.

%%Month%%%%Day%% (C) - This is the correct syntax to match the month and day in the file name. For example, if the file name is "MAY15", the pattern will be %%MMMM%%dd.

In Salesforce Marketing Cloud, landing pages can use the Core Library and the Platform Library of Server-Side JavaScript (SSJS). The Core Library provides fundamental functions, while the Platform Library provides additional functionality to interact with Marketing Cloud-specific features.

Core Library: Provides basic SSJS functionality.

Platform Library: Extends SSJS functionality with additional methods specific to Marketing Cloud.

When using the REST Authorization Service to obtain an OAuth access token, the standard method to include this token in subsequent API requests is by adding it to the Authorization header with the Bearer scheme.

Correct Method: Authorization: Bearer YOUR_ACCESS_TOKEN

This format is a standard practice for OAuth 2.0 token usage.

Salesforce Authentication and Access Tokens

To analyze the Send, Click, and Open Data Views and transfer the data to the SFTP, the developer should build the following activities:

Query Activity - To query and gather the data from the Send, Click, and Open Data Views.

Data Extension Extract - To extract the queried data from the data extension and prepare it for transfer to the SFTP.

To select a subset of records that contain a phone number, the field that ensures the phone number is valid and non-blank should be used.

ValidPhone Field: The ValidPhone field is a formula field that evaluates to 'true' if the phone number is valid. This ensures that only records with a valid phone number are included in the synchronization.

Salesforce Data Synchronization

The error message "Cannot Perform 'Post' on objects of type 'SentEvent'" indicates that the SentEvent object is not updatable via the SOAP API. The SentEvent object is typically read-only and is used for tracking purposes.

Read-Only Object: The SentEvent object is used to log events and is not designed to be modified via API calls. This is why attempts to perform POST operations on it will result in an error.

Salesforce SOAP API Error Codes

Before importing a compressed file into Marketing Cloud, a File Transfer activity is required to move and decompress the file. The File Transfer activity allows you to specify the source and destination locations and to decompress the file, making it ready for the import process.

Salesforce File Transfer Activity

A "401 Unauthorized" error typically indicates an issue with authentication or permissions. Since the Client ID and Client Secret have been successfully used in other REST calls, the most likely cause is insufficient permissions for sending emails.

Check Send Permissions: Ensure that the appropriate permissions for sending emails have been granted to the Client ID and Client Secret in the Installed Packages. Without these permissions, the API call will fail with a 401 error.

Salesforce Installed Packages and Permissions

When working with a REST API that returns data in JavaScript Object Notation (JSON) and needing to efficiently ingest the data and write it to a data extension, the developer should use the Server-Side JavaScript function ParseJSON. This function parses a JSON string and converts it into a JavaScript object, which can then be manipulated and written to a data extension.

After using LookupRows to retrieve data when building a dynamic email, the next step before using this rowset within a FOR loop is to use RowCount to ensure the rowset contains data (D). This validation ensures that there are rows to iterate over, preventing potential errors or empty iterations in the FOR loop.

Example:

SET @rows = LookupRows("DataExtensionName", "FieldName", "Value") SET @rowCount = RowCount(@rows) IF @rowCount > 0 THEN FOR @i = 1 TO @rowCount DO SET @row = Row(@rows, @i) /* process each row */ NEXT @i ENDIF
