Hi @PatHua ,

Make sure that your admin performed all prerequisites. Salesforce applies usage restrictions to connected apps. The permissions in the following table are required for a successful first-time authentication. If you lack these permissions, Salesforce blocks the connection and requires an admin to install the Databricks connected app.

ConditionRequired permission

You can find more information about this at salesforce site:

https://help.salesforce.com/s/articleView?id=005132365&type=1

Once you performed above steps, here's a step by step instruction how to create connection to salesforce:

https://docs.databricks.com/aws/en/connect/managed-ingestion#create-a-connection

Also, pay attention to following step. 

Please check also it:
https://docs.databricks.com/aws/en/ingestion/lakeflow-connect/salesforce-faq

there is written:
"In September 2025, Salesforce began restricting the use of uninstalled connected apps. When you create or reauthorize a connection, a Salesforce admin must now install the Databricks connected app in your Salesforce instance or grant you heightened permissions. For more information, see Prepare for Connected App Usage Restrictions Change in the Salesforce documentation."

so can be smth like:


In Salesforce: Setup → Connected Apps OAuth Usage

Find Databricks connected app and Install / Allow it. Databricks Documentation
OR grant you the right permission:

If API Access Control is OFF: give your user “Approve Uninstalled Connected Apps” Databricks Documentation

If API Access Control is ON: give Customize Application + (Manage Connected Apps or Modify All Data)

Hi guys
Thank you so much for these pre-requisites to check !
Whatever he likes it or not, my salesforce adm will some tasks to do 😉

Hi guys 
Sorry to bother you again...I know, the salesforce adm in my company is quite "narrow-minded" regarding security issues, and I don't know enough about security protocol to answer him.
Do you know why we need a "Connected App" usage while we are defining an "External App" one ?
In a word, what OAUTH system is finally used ?

Thank you so much
Patrick
