How do I programmatically update an existing submitted webform submission in Drupal?

Question

I am attempting to use PHP in Drupal rules to update the values in submitted webform submissions. I can access and view the data correctly. When I assign a new value to a field, it will even show up correctly if I use:

print $submission->data[61][0];

But, when I navigate to the submission results page, the field is not updated.

I tried using the webform_submission_update() function to push my change, but still no luck.

Question: How do I programmatically update an existing submitted webform submission in Drupal?

Code:

$submission = webform_menu_submission_load($nid, $sid);

// Two ways I've tried to update the data
$submission->data[61][0] = "testwork";
$submission->data[61]['value'][0] = 'Declined';

// If I do print $submission->data[61][0]; it will show the new value.

webform_submission_update($nid, $submission);

Answer 1

The problem was 2-fold:

I didn't use node_load() on the NID of the webform.

I didn't use the correct webform function to load the data.

// Load the node and submission.
$node = node_load(3333);
$sid = $list_itemb->sid;
$submission = webform_get_submission($node->nid, $sid);
    
// Change submission data.
$submission->data[61][0] = 'Update';
    
// Finally, update the submission.
webform_submission_update($node, $submission);
