Daily updated image to be posted on Slack

Hi, I would like to automate slack to post a daily viz on my workplace Slack channel.

Currently I have copied the snap.redash URL link to a PNG file using Zapier to schedule to post in slack channel daily.

It works fine however the PNG file being posted is not the latest imagine on slack. Any ideas or how can make it work?

Thanks, Richie

Are you using app.redash.io? Where did you find the snap.redash.io URL?

Hi Jesse, sorry it is the latest image, however I want it to contain a snapshot, is there a way of doing this?

Then I use Image Embed URL Link.

That should work. I wonder if Slack has cached the image. In which case you can use this trick from the documentation. Just append a ?no-cache query string to the image embed URL.
