Checking status of layer calculation using API

I wrote a python script that updates the values in a dataset and then returns a static image of the map it’s connected to.

The problem is if I download the image too soon after updating the dataset, one of the visualization layers on the map that requires a lot of calculations won’t show up.

I don’t want to have to set a manual wait time in the code because the size of the data I’m uploading could range from 100 to 10,000 data points.

Is there an API url I could call that would know when a layer is being updated and when it has finished?

I have tried using vizualization url but could not find anything in the JSON data about an update status.

img_url1 = 'https://%s.carto.com/api/v2/viz/%s/viz.json/?api_key=%s&' %(self.options['u'], map_id, self.options['k'])
r1 = requests.get(img_url1)
print(json.dumps(r4.json(), indent=2))

On a similar thread someone sugested using this to refresh the the_geom data but I had no luck there either:

refresh_url = "https://{username}.carto.com/api/v2/sql?q=UPDATE table SET the_geom = cdb_latlng(latitude, longitude)&api_key={api_key}".format(username=self.options['u'], api_key=self.options['k'])
r4 = requests.get(refresh_url)
print(json.dumps(r4.json(), indent=2))

I have tried using the named map API but the ‘Last Updated’ field shows the time when the update started not finished, and the ‘Date’ field just shows the current time.

img_url2 = 'https://{user}.carto.com/api/v1/map/named/{template}/jsonp?auth_token={auth_token}&callback=callback'.format(user=self.options['u'], template=tpl_name, auth_token=self.options['k'])
r2 = requests.get(img_url2)
print(r2.headers)
