Hi @jamescosten ,
You can add a Filter array before condition to find the specific row.
Then check if result of filter array is empty. If it is empty, add a new row.
Please try this:
As for 'Key Value' in update a row, you can try below expression:
first(body('Filter_array'))?['KeyColumnName']
Best regards,
