This integration allows you to deliver personalized, data-driven marketing campaigns across email, SMS, social media, and other digital channels, creating impactful customer experiences. Here's how this integration adds value: - **Unified customer profiles**: Enrich Salesforce Marketing Cloud with first-party data, creating comprehensive customer profiles for precise targeting and segmentation. - **Personalized, omnichannel campaigns**: Use insights to craft hyper-relevant campaigns in SFMC, ensuring personalized messaging across email, push notifications, and social media. - **Real-time data synchronization**: Sync real-time customer data with SFMC to activate timely campaigns triggered by user behavior, preferences, or lifecycle stages. - **Enhanced retargeting**: Use dynamic audience data to re-engage customers with personalized offers, reminders, or loyalty incentives. - **Cross-channel consistency**: Align your Salesforce Marketing Cloud campaigns with broader omnichannel strategies, ensuring seamless and cohesive customer journeys. - **Improved ROI**: Optimize campaign performance by focusing on high-value audience segments, improving engagement rates, and reducing wasted marketing spend. - **Actionable insights**: Combine rich customer data with SFMC's analytics capabilities to continuously refine and improve your marketing strategies. ## Destination connector overview | Attribute | Value | | --- | --- | | **Platform type** | Email campaigns | | **Cookie Sync** | No | | **Connecting protocol** | REST (enhanced authentication) | | **Real-time data sync** | Yes | | **Syncs Data On** | Add, Update, Remove | | **Allowed setting multiple connectors** | Yes | | **ProfileVars Support** | Yes | ## Before you begin Because of the specifics of the Marketing Cloud Platform, preliminary setup is required within Marketing Cloud to enable pairing with Data Activation. Specifically, a **user with the necessary permissions** on the Marketing Cloud interface **must create two Data Extensions**. ### SupermetricsAudienceProd The name of the Data Extension should be `SupermetricsAudienceProd`. The following attributes need to be configured: | Field Name | Data Type | Notes | | --- | --- | --- | | SubscriberId | Text | Must match the SubscriberId in SFMC. Set the length to 500 if not set. Non nullable | | SegmentId | Number | Stores the selection ID or Journey's stepId (UUID v4 string). Non nullable | | Status | Boolean | Non nullable | | EventDate | Date | Nullable | > [!NOTE] > Note > > When using the connector in a Journey (Orchestration), 'SegmentId' contains the journey's stepId. This stepId is a 'String' instead of an 'Integer', as stepIds are a UUID v4. ### SupermetricsVariablesProd The name of the Data Extension should be `SupermetricsVariablesProd`. This data extension serves as a table designed to hold the profile data for users included in a specific selection. The following attributes need to be configured: | Field Name | Data Type | Notes | | --- | --- | --- | | `SubscriberId` | Text | Must match the SubscriberId in SFMC. Length 500 and non nullable | | `SegmentId` | Number | Non nullable | | `Key` | Text | Length 50, non nullable | | `Value` | Text | Length 500, non nullable | | `EventDate` | Date | Nullable | ### Additional configuration notes - **SubscriberId**: If your SubscriberIds in Salesforce Marketing Cloud could contain non-numeric values, change the type of SubscriberId from Number to Text. - **Tenant-specific endpoint**: Make sure to only provide the subdomain for your account. For example, if you have the endpoint `https://ab-xxxinqc8hsgnywdv9j0xxxxx0.rest.marketingcloudapis.com/`, configure the domain field as: `ab-xxxinqc8hsgnywdv9j0xxxxx0` - **External Key**: Ensure you change the default external key in the data extension to `SupermetricsAudienceProd` and `SupermetricsVariablesProd` respectively. ### How data flows work When a Marketing Cloud interaction is configured in a selection: - **When a user joins a selection**: Data is sent to both `SupermetricsAudienceProd` AND `SupermetricsVariablesProd` - **When profile data is modified within a selection**: Data is sent to `SupermetricsVariablesProd` only - **When a profile leaves a selection**: Data is sent to `SupermetricsAudienceProd` only ## Instructions 1. On the Data Activation platform, select **Connectors** in the left-side navigation bar. 2. Select **Server to Server** and click **New Connector**. 3. Select **Salesforce Marketing Cloud**and provide the required configuration, including your tenant subdomain and authentication credentials. > [!NOTE] > Note > > It currently isn't possible to create two Marketing Cloud connectors with the same partnerNumber. If this is needed, reach out to the support team and explain your use case. ## Error handling For the Salesforce Marketing Cloud connector, we report Salesforce-specific error codes. Error documentation can be found in the [Salesforce error handling documentation](https://developer.salesforce.com/docs/marketing/marketing-cloud/guide/error-handling.html). The following error codes are Data Activation-related: - Timeout - Other error - Invalid credentials To read more about these errors, see [Using journey and audience connectors](/v1/docs/using-audience-and-journey-connectors). FAQs **Is my connector using SOAP or REST?** REST **I get a 400 bad request error**. This can have multiple causes, but please verify that the External Key in your data extension is actually `SupermetricsVariablesProd` and `SupermetricsAudienceProd`. **Can I target users based on different identifiers?** Yes, to do this you need to create two new data extensions in Marketing Cloud as well as creating a new connector with advanced settings. The Segment key and Variables key need to match the External Key of the data extensions. Please ensure that the same fields are available as described earlier in the article. ## More resources - [How to build audiences](/v1/docs/how-to-build-audiences) - [How to build journeys](/v1/docs/how-to-build-journeys) - [How to measure goals and outcome signals](/v1/docs/how-to-measure-goals-and-outcome-signals)
