How to Edit Calculated Fields Without Restarting

For advanced users, Yellowfin provides a REST API that allows programmatic updates to calculated fields. This method is particularly useful for automated workflows and integrations.

To use the API:

Authenticate with the Yellowfin API using your credentials.
Construct a PUT request to update the calculated field.
Include the new formula in the request body.
Execute the request to apply the changes.
Monitor the response to confirm successful updates.
