Use the Amazon SageMaker and Salesforce Data Cloud integration to power your Salesforce apps with AI/ML | Amazon Web Services

This post is co-authored by Daryl Martis, Director of Product, Salesforce Einstein AI.

This is the second post in a series discussing the integration of Salesforce Data Cloud and Amazon SageMaker. In Part 1, we show how the Salesforce Data Cloud and Einstein Studio integration with SageMaker allows businesses to access their Salesforce data securely using SageMaker and use its tools to build, train, and deploy models to endpoints hosted on SageMaker. The endpoints are then registered to the Salesforce Data Cloud to activate predictions in Salesforce.

In this post, we expand on this topic to demonstrate how to use Einstein Studio for product recommendations. You can use this integration for traditional models as well as large language models (LLMs).

Solution overview

In this post, we demonstrate how to create a predictive model in SageMaker to recommend the next best product to your customers by using historical data such as customer demographics, marketing engagements, and purchase history from Salesforce Data Cloud.

We use the following sample dataset. To use this dataset in your Data Cloud, refer to Create Amazon S3 Data Stream in Data Cloud.

The following attributes are needed to create the model:

• Club Member – If the customer is a club member
• Campaign – The campaign the customer is a part of
• State – The state or province the customer resides in
• Month – The month of purchase
• Case Count – The number of cases raised by the customer
• Case Type Return – Whether the customer returned any product within the last year
• Case Type Shipment Damaged – Whether the customer had any shipments damaged in the last year
• Engagement Score – The level of engagement the customer has (response to mailing campaigns, logins to the online store, and so on)
• Tenure – The tenure of the customer relationship with the company
• Clicks – The average number of clicks the customer has made within a week prior to purchase
• Pages Visited – The average number of pages the customer has visited within a week prior to purchase
• Product Purchased – The actual product purchased
• Id – The ID of the record
• DateTime – The timestamp of the dataset

The product recommendation model is built and deployed on SageMaker and is trained using data in the Salesforce Data Cloud. The following steps give an overview of how to use the new capabilities launched in SageMaker for Salesforce to enable the overall integration:

1. Set up the Amazon SageMaker Studio domain and OAuth between Salesforce and the AWS accounts.
2. Use the newly launched capability of the Amazon SageMaker Data Wrangler connector for Salesforce Data Cloud to prepare the data in SageMaker without copying the data from Salesforce Data Cloud.
3. Train a recommendation model in SageMaker Studio using training data that was prepared using SageMaker Data Wrangler.
4. Package the SageMaker Data Wrangler container and the trained recommendation model container in an inference pipeline so the inference request can use the same data preparation steps you created to preprocess the training data. The real-time inference call data is first passed to the SageMaker Data Wrangler container in the inference pipeline, where it is preprocessed and passed to the trained model for product recommendation. For more information about this process, refer to New — Introducing Support for Real-Time and Batch Inference in Amazon SageMaker Data Wrangler. Although we use a specific algorithm to train the model in our example, you can use any algorithm that you find appropriate for your use case.
5. Use the newly launched SageMaker provided project template for Salesforce Data Cloud integration to streamline implementing the preceding steps by providing the following templates:
   1. An example notebook showcasing data preparation, building, training, and registering the model.
   2. The SageMaker provided project template for Salesforce Data Cloud integration, which automates creating a SageMaker endpoint hosting the inference pipeline model. When a version of the model in the Amazon SageMaker Model Registry is approved, the endpoint is exposed as an API with Amazon API Gateway using a custom Salesforce JSON Web Token (JWT) authorizer. API Gateway is required to allow Salesforce Data Cloud to make predictions against the SageMaker endpoint using a JWT token that Salesforce creates and passes with the request when making predictions from Salesforce. JWT can be used as a part of OpenID Connect (OIDC) and OAuth 2.0 frameworks to restrict client access to your APIs.
6. After you create the API, we recommend registering the model endpoint in Salesforce Einstein Studio. For instructions, refer to Bring Your Own AI Models to Salesforce with Einstein Studio

The following diagram illustrates the solution architecture.

Create a SageMaker Studio domain

First, create a SageMaker Studio domain. For instructions, refer to Onboard to Amazon SageMaker Domain. You should note down the domain ID and execution role that is created and will be used by your user profile. You add permissions to this role in subsequent steps.

The following screenshot shows the domain we created for this post.

The following screenshot shows the example user profile for this post.

Set up the Salesforce connected app

Next, we create a Salesforce connected app to enable the OAuth flow from SageMaker Studio to Salesforce Data Cloud. Complete the following steps:

1. Log in to Salesforce and navigate to Setup.
2. Search for App Manager and create a new connected app.
3. Provide the following inputs:
   1. For Connected App Name, enter a name.
   2. For API Name, leave as default (it’s automatically populated).
   3. For Contact Email, enter your contact email address.
   4. Select Enable OAuth Settings.
   5. For Callback URL, enter https://<domain-id>.studio.<region>.sagemaker.aws/jupyter/default/lab, and provide the domain ID that you captured while creating the SageMaker domain and the Region of your SageMaker domain.
      
4. Under Selected OAuth Scopes, move the following from Available OAuth Scopes to Selected OAuth Scopes and choose Save:
   1. Manage user data via APIs (api)
   2. Perform requests at any time (refresh_token, offline_access)
   3. Perform ANSI SQL queries on Salesforce Data Cloud data (Data Cloud_query_api)
   4. Manage Salesforce Customer Data Platform profile data (Data Cloud_profile_api
   5. Access the identity URL service (id, profile, email, address, phone)
   6. Access unique user identifiers (openid)

For more information about creating a connected app, refer to Create a Connected App.

5. Return to the connected app and navigate to Consumer Key and Secret.
6. Choose Manage Consumer Details.
   
7. Copy the key and secret.

You may be asked to log in to your Salesforce org as part of the two-factor authentication here.

8. Navigate back to the Manage Connected Apps page.
9. Open the connected app you created and choose Manage.
10. Choose Edit Policies and change IP Relaxation to Relax IP restrictions, then save your settings.

Configure SageMaker permissions and lifecycle rules

In this section, we walk through the steps to configure SageMaker permissions and lifecycle management rules.

Create a secret in AWS Secrets Manager

Enable OAuth integration with Salesforce Data Cloud by storing credentials from your Salesforce connected app in AWS Secrets Manager:

1. On the Secrets Manager console, choose Store a new secret.
2. Select Other type of secret.
3. Create your secret with the following key-value pairs:

   { "identity_provider": "SALESFORCE", "authorization_url": "https://login.salesforce.com/services/oauth2/authorize", "token_url": "https://login.salesforce.com/services/oauth2/token", "client_id": "<YOUR_CONSUMER_KEY>", "client_secret": "<YOUR_CONSUMER_SECRET>"
   “issue_url”: “<YOUR_SALESFORCE_ORG_URL>”
   }

   

4. Add a tag with the key sagemaker:partner and your choice of value.
5. Save the secret and note the ARN of the secret.

Configure a SageMaker lifecycle rule

The SageMaker Studio domain execution role will require AWS Identity and Access Management (IAM) permissions to access the secret created in the previous step. For more information, refer to Creating roles and attaching policies (console).

1. On the IAM console, attach the following polices to their respective roles (these roles will be used by the SageMaker project for deployment):
   1. Add the policy AmazonSageMakerPartnerServiceCatalogProductsCloudFormationServiceRolePolicy to the service role AmazonSageMakerServiceCatalogProductsCloudformationRole.
   2. Add the policy AmazonSageMakerPartnerServiceCatalogProductsApiGatewayServiceRolePolicy to the service role AmazonSageMakerServiceCatalogProductsApiGatewayRole.
   3. Add the policy AmazonSageMakerPartnerServiceCatalogProductsLambdaServiceRolePolicy to the service role AmazonSageMakerServiceCatalogProductsLambdaRole.
2. On the IAM console, navigate to the SageMaker domain execution role.
3. Choose Add permissions and select Create an inline policy.
4. Enter the following policy in the JSON policy editor:

   { "Version": "2012-10-17", "Statement": [
   { "Effect": "Allow", "Action": [ "secretsmanager:GetSecretValue", "secretsmanager:PutSecretValue"
   ], "Resource": "arn:aws:secretsmanager:*:*:secret:*", "Condition": { "ForAnyValue:StringLike": { "aws:ResourceTag/sagemaker:partner": "*"
   }
   }
   },
   { "Effect": "Allow", "Action": [ "secretsmanager:UpdateSecret"
   ], "Resource": "arn:aws:secretsmanager:*:*:secret:AmazonSageMaker-*"
   }
   ]
   }

SageMaker Studio lifecycle configuration provides shell scripts that run when a notebook is created or started. The lifecycle configuration will be used to retrieve the secret and import it to the SageMaker runtime.

5. On the SageMaker console, choose Lifecycle configurations in the navigation pane.
6. Choose Create configuration.
7. Leave the default selection Jupyter Server App and choose Next.
8. Give the configuration a name.
9. Enter the following script in the editor, providing the ARN for the secret you created earlier:

   #!/bin/bash
   set -eux cat > ~/.sfgenie_identity_provider_oauth_config <<EOL
   { "secret_arn": "<YOUR_SECRETS_ARN>"
   }
   EOL

10. Choose Submit to save the lifecycle configuration.
11. Choose Domains in the navigation pane and open your domain.
12. On the Environment tab, choose Attach to attach your lifecycle configuration.
13. Choose the lifecycle configuration you created and choose Attach to domain.
14. Choose Set as default.

If you are a returning user to SageMaker Studio, in order to ensure Salesforce Data Cloud is enabled, upgrade to the latest Jupyter and SageMaker Data Wrangler kernels.

This completes the setup to enable data access from Salesforce Data Cloud to SageMaker Studio to build AI and machine learning (ML) models.

Create a SageMaker project

To start using the solution, first create a project using Amazon SageMaker Projects. Complete the following steps:

1. In SageMaker Studio, under Deployments in the navigation pane, choose Projects.
2. Choose Create project.
3. Choose the project template called Model deployment for Salesforce.
4. Choose Select project template.
   
5. Enter a name and optional description for your project.
6. Enter a model group name.
7. Enter the name of the Secrets Manager secret that you created earlier.
8. Choose Create project.

The project may take 1–2 minutes to initiate.

You can see two new repositories. The first one is for sample notebooks that you can use as is or customize to prepare, train, create, and register models in the SageMaker Model Registry. The second repository is for automating the model deployment, which includes exposing the SageMaker endpoint as an API.

9. Choose clone repo for both notebooks.

For this post, we use the product recommendation example, which can be found in the sagemaker-<YOUR-PROJECT-NAME>-p-<YOUR-PROJECT-ID>-example-nb/product-recommendation directory that you just cloned. Before we run the product-recommendation.ipynb notebook, let’s do some data preparation to create the training data using SageMaker Data Wrangler.

Prepare data with SageMaker Data Wrangler

Complete the following steps:

1. In SageMaker Studio, on the File menu, choose New and Data Wrangler flow.
   
2. After you create the data flow, choose (right-click) the tab and choose Rename to rename the file.
3. Choose Import data.
   
4. Choose Create connection.
   
5. Choose Salesforce Data Cloud.
   
6. For Name, enter salesforce-data-cloud-sagemaker-connection.
7. For Salesforce org URL, enter your Salesforce org URL.
8. Choose Save + Connect.
   
9. In the Data Explorer view, select and preview the tables from the Salesforce Data Cloud to create and run the query to extract the required dataset.
10. Your query will look like below and you may use the table name that you used while uploading data in Salesforce Data Cloud.

    SELECT product_purchased__c, club_member__c, campaign__c, state__c, month__c, case_count__c,case_type_return__c, case_type_shipment_damaged__c, pages_visited__c,engagement_score__c, tenure__c, clicks__c, id__c
    FROM Training_Dataset_for_Sagemaker__dll

11. Choose Create dataset.

Creating the dataset may take some time.

In the data flow view, you can now see a new node added to the visual graph.

For more information on how you can use SageMaker Data Wrangler to create Data Quality and Insights Reports, refer to Get Insights On Data and Data Quality.

SageMaker Data Wrangler offers over 300 built-in transformations. In this step, we use some of these transformations to prepare the dataset for an ML model. For detailed instructions on how to implement these transformations, refer to Transform Data.

12. Use the Manage columns step with the Drop column transform to drop the column id__c.
    
13. Use the Handle missing step with the Drop missing transform to drop rows with missing values for various features. We apply this transformation on all columns.
    
14. Use a custom transform step to create categorical values for state__c, case_count__c, and tenure features. Use the following code for this transformation:

    from pyspark.sql.functions import when States_List = [‘Washington’, ‘Massachusetts’, ‘California’, ‘Minnesota’, ‘Vermont’, ‘Colorado’, ‘Arizona’] df.withColumn(“club_member__c”,df.club_member__c.cast(‘string’))
    df.withColumn(“month__c”,df.month__c.cast(‘string’))
    df.withColumn(“case_type_return__c”,df.case_type_return__c.cast(‘string’))
    df.withColumn(“case_type_shipment_damaged__c”,df.case_type_shipment_damaged__c.cast(‘string’)) df = df.withColumn(‘state__c’, when(df.state__c.isin(States_List), df.state__c).otherwise(“Other”)) df = df.withColumn(‘case_count__c’, when(df.case_count__c == 0, “No Cases”).otherwise( when(df.case_count__c <= 2, “1 to 2 Cases”).otherwise(“Greater than 2 Cases”))) df = df.withColumn(‘tenure__c’, when(df.tenure__c < 1, “Less than 1 Year”).otherwise( when(df.tenure__c == 1, “1 to 2 Years”).otherwise(when(df.tenure__c ==2, “2 to 3 Years”).otherwise(when(df.tenure__c == 3, “3 to 4 Years”).otherwise(“Grater Than 4 Years”)))))

    

15. Use the Process numeric step with the Scale values transform and choose Standard scaler to scale clicks__c, engagement__score, and pages__visited__c features.
    
16. Use the Encode categorical step with the One-hot encode transform to convert categorical variables to numeric for case__type__return___c, case__type_shipment__damaged, month__c, club__member__c, and campaign__c features (all features except clicks__c, engagement__score, pages__visited__c, and product_purchased__c).
    

Model building, training, and deployment

To build, train, and deploy the model, complete the following steps:

1. Return to the SageMaker project, open the product-recommendation.ipynb notebook, and run a processing job to preprocess the data using the SageMaker Data Wrangler configuration you created.
2. Follow the steps in the notebook to train a model and register it to the SageMaker Model Registry.
   
3. Make sure to update the model group name to match with the model group name that you used while creating the SageMaker project.

To locate the model group name, open the SageMaker project that you created earlier and navigate to the Settings tab.

Similarly, the flow file referenced in the notebook must match with the flow file name that you created earlier.

4. For this post, we used product-recommendation as the model group name, so we update the notebook with project-recommendation as the model group name in the notebook.

After the notebook is run, the trained model is registered in the Model Registry. To learn more about the Model Registry, refer to Register and Deploy Models with Model Registry.

5. Select the model version you created and update the status of it to Approved.

Now that you have approved the registered model, the SageMaker Salesforce project deploy step will provision and trigger AWS CodePipeline.

CodePipeline has steps to build and deploy a SageMaker endpoint for inference containing the SageMaker Data Wrangler preprocessing steps and the trained model. The endpoint will be exposed to Salesforce Data Cloud as an API through API Gateway. The following screenshot shows the pipeline prefixed with Sagemaker-salesforce-product-recommendation-xxxxx. We also show you the endpoints and API that gets created by the SageMaker project for Salesforce.

If you would like, you can take a look at the CodePipeline deploy step, which uses AWS CloudFormation scripts to create SageMaker endpoint and API Gateway with a custom JWT authorizer.

When pipeline deployment is complete, you can find the SageMaker endpoint on the SageMaker console.

You can explore the API Gateway created by the project template on the API Gateway console.

Choose the link to find the API Gateway URL.

You can find the details of the JWT authorizer by choosing Authorizers on the API Gateway console. You can also go to the AWS Lambda console to review the code of the Lambda function created by project template.

To discover the schema to be used while invoking the API from Einstein Studio, choose Information in the navigation pane of the Model Registry. You will see an Amazon Simple Storage Service (Amazon S3) link to a metadata file. Copy and paste the link into a new browser tab URL.

Let’s look at the file without downloading it. On the file details page, choose the Object actions menu and choose Query with S3 Select.

Choose Run SQL query and take note of the API Gateway URL and schema because you will need this information when registering with Einstein Studio. If you don’t see an APIGWURL key, either the model wasn’t approved, deployment is still in progress, or deployment failed.

Use the Salesforce Einstein Studio API for predictions

Salesforce Einstein Studio is a new and centralized experience in Salesforce Data Cloud that data science and engineering teams can use to easily access their traditional models and LLMs used in generative AI. Next, we set up the API URL and client_id that you set in Secrets Manager earlier in Salesforce Einstein Studio to register and use the model inferences in Salesforce Einstein Studio. For instructions, refer to Bring Your Own AI Models to Salesforce with Einstein Studio.

Clean up

To delete all the resources created by the SageMaker project, on the project page, choose the Action menu and choose Delete.

To delete the resources (API Gateway and SageMaker endpoint) created by CodePipeline, navigate to the AWS CloudFormation console and delete the stack that was created.

Conclusion

In this post, we explained how you can build and train ML models in SageMaker Studio using SageMaker Data Wrangler to import and prepare data that is hosted on the Salesforce Data Cloud and use the newly launched Salesforce Data Cloud JDBC connector in SageMaker Data Wrangler and first-party Salesforce template in the SageMaker provided project template for Salesforce Data Cloud integration. The SageMaker project template for Salesforce enables you to deploy the model and create the endpoint and secure an API for a registered model. You then use the API to make predictions in Salesforce Einstein Studio for your business use cases.

Although we used the example of product recommendation to showcase the steps for implementing the end-to-end integration, you can use the SageMaker project template for Salesforce to create an endpoint and API for any SageMaker traditional model and LLM that is registered in the SageMaker Model Registry. We look forward to seeing what you build in SageMaker using data from Salesforce Data Cloud and empower your Salesforce applications using SageMaker hosted ML models!
