Hello, 

My goal is simple: I want to duplicate an existing workbook on  

Tableau Cloud and update the custom SQL inside its embedded  

datasource — all programmatically via Python. 

I am using the Tableau Server Client (TSC) Python library to programmatically  

update the custom SQL inside an embedded datasource in a workbook, then  

republish it to Tableau Cloud as a new workbook. 

**Environment:** 

- Tableau Cloud (us-east-1) 

- Python tableauserverclient (TSC) library 

- Datasource: Amazon Redshift (embedded in workbook, not a published datasource) 

- Connection goes through Tableau Bridge (private network/VPN) 

**What I am doing:** 

1. Download the workbook WITHOUT extract using include_extract=False → get small .twb file 

2. Parse the .twb XML and replace the custom SQL in the embedded datasource 

3. Republish as a new workbook using server.workbooks.publish() 

**The Problem:** 

Every publish attempt fails with: 

    403132: Forbidden 

    <workbook_name> failed to establish a connection to your datasource. 

**Everything I have tried:** 

1. Passing ConnectionItem with credentials: 

    conn_item = ConnectionItem() 

    conn_item.server_address = "<redshift-host>" 

    conn_item.server_port    = "5439" 

    conn_item.username       = "<username>" 

    conn_item.password       = "<password>" 

    conn_item.embed_password = True 

    server.workbooks.publish(..., connections=[conn_item]) 

2. Using skip_connection_check=True: 

    server.workbooks.publish(..., skip_connection_check=True) 

    → Confirmed skipConnectionCheck=true IS in the POST URL 

3. Both combined — still 403132 

4. Neither (no connections parameter) — still 403132 

5. Confirmed the XML being sent is correct and contains  

   <connectionCredentials> with the right server address,  

   username, and embed="true" 

**Key observation:** 

The original workbook works fine on Tableau Cloud and its extract  

refresh runs through Tableau Bridge. Tableau Cloud has no direct  

network path to Redshift — it always goes through Bridge. 

My hypothesis is that Tableau Cloud ignores skipConnectionCheck  

for Bridge-dependent connections and always tries a direct  

connection validation, which fails because Redshift is on a  

private network. 

**Questions:** 

1. Is it possible to publish a .twb via REST API when the datasource  

   connects through Tableau Bridge? 

2. Does skipConnectionCheck=true not apply to Bridge connections? 

3. Is there a correct way to publish and tell Tableau Cloud to use  

   the existing Bridge-linked credentials rather than validating  

   directly? 

Code:

server = TSC.Server(SERVER_URL, use_server_version=True)
with server.auth.sign_in(auth):
    source_wb = server.workbooks.get_by_id(SOURCE_WORKBOOK_ID)
    buf = io.BytesIO()
    server.workbooks.download(
        SOURCE_WORKBOOK_ID,
        filepath=buf,
        include_extract=False,
    )
    buf.seek(0)
    new_wb_item = TSC.WorkbookItem(
        name=NEW_WORKBOOK_NAME,
        project_id=TARGET_PROJECT_ID,
    )
    new_wb_item.show_tabs = source_wb.show_tabs
    #
    # # 5. Publish using the modified source connection
    new_wb = server.workbooks.publish(
        new_wb_item,
        buf,
        mode=TSC.Server.PublishMode.CreateNew,
        # connections=[source_conn],  # <-- Tried with conn also 
        skip_connection_check=True
    )

Thank you.

Hi, 

I'd be grateful if someone could help point me to how to solve this problem? I'm trying to calculate the variable revenue generated by the number of people who register for an event, using a parameter to input a hypothetical number of registrants. 

Different types of registrants get charge different amounts  - so for example, a 'Member Participant' might get charged $750 to attend, a guest might get charged $850. 

At this stage i want to calculate what the revenue from x numbers of 'Member participants'  would be. I've tried all sorts of variations of the attached formula, adding in ATTR, averaging the 'Amount' and using a calculated field called 'Average Amount' in place of 'Amount, but it keeps saying it cannot mix aggregate and non-aggregates. 

Currently the formula is summing all the $750's that have actually registered, and then multiplying by the 'Member Attendees Select' parameter, whereas i want it to simply take the $750 and multiply it by the parameter.  

Any guidance would be greatly appreciated. I am going cross-eyed from having spent so long trying all sorts of permutations, and ways around the problem. 

Sincerely, 

Andy

Title:

How to Generate Notification Alerts in Tableau Next for Leads with Contacted Date = NULL?

Question:

Hi Experts,

We are implementing Salesforce Data Cloud and Tableau Next for Admissions Lead Management.

Current Setup

• Lead data is ingested into Salesforce Data Cloud.
• Data Objects and Data Streams are configured successfully.
• A Semantic Model has been created in Tableau Next.
• We created a metric called "No Contact Leads" using a calculated field where Contacted Date = NULL.
• Metric Following, Goal Thresholds, and Metric Insight Summary are enabled.
• AI-generated insights and trend analysis are working correctly.

Business Requirement

We want to proactively identify leads that have not been contacted.

Example:

Contacted Date = NULL

If a lead remains uncontacted, or if the count of uncontacted leads exceeds a threshold, we want users to receive a notification through the Salesforce/Tableau Next notification panel (bell icon).

What We Have Already Configured

• Calculated Field: Is No Contact
• Metric: No Contact Leads
• Goal Threshold
• Metric Following
• Insight Summary

We can see the threshold status and AI insights, but we cannot find a way to generate notifications in the Salesforce/Tableau Next notification panel.

Questions

1. Does Tableau Next support native notification alerts for Semantic Model Metrics?
2. Can Metric Following generate notifications in the Salesforce notification bell?
3. Is Tableau Pulse required for this type of alerting?
4. Has anyone implemented threshold-based notifications for Tableau Next metrics?
5. Is the recommended approach to use:
   • Tableau Next Metrics
   • Tableau Pulse
   • Salesforce Flow
   • Data Cloud Calculated Insights
   • Agentforce
   • Custom Notifications
6. What is the best-practice architecture for generating alerts when Contacted Date is NULL or when No Contact Leads exceed a threshold?

Any guidance, documentation references, or implementation examples would be greatly appreciated.

Thank you.
