CORS - Endpoint issue with CORS

[luismolina]

Hi, I have created an endpoint to return information from a RAG system, but when trying to be consumed by external apps, they got a CORS error because they are in a different domain and use javascript to call the API. How can I implement CORS in my endpoint?

Regards.

Hi @luismolina, To address the CORS (Cross-Origin Resource Sharing) error that external applications are encountering when trying to access your Databricks API endpoint, you can implement CORS in your Databricks workspace.

Here are the steps to do so:

Configure CORS Settings in Databricks

1. Access the Databricks Admin Console: Log in to your Databricks workspace as an admin user and navigate to the Admin Console.
2. Enable CORS: In the Admin Console, locate the "CORS" section and enable it.
3. Add Allowed Origins: In the "Allowed Origins" field, add the URLs of the external applications that need to access your API. You can use wildcards (e.g., https://*.example.com) to allow access from multiple subdomains.
4. Save the Changes: After adding the allowed origins, save the CORS configuration.

Hey I am running into the same issue, but even while logged in as a workspace admin cannot see the CORS section. Is there an additional feature I would need to enable to see this. Thanks @Kaniz_Fatma

@Kaniz_Fatma My company is running into the same issue serving a model via REST API for a web application to call, and like @mcoffey I'm not able to see the CORs section after logging into the workspace as an admin and viewing the settings for the workspace (see below screenshot)
