Yes, using the webhook should be the simplest way.
So select Zapier Schedule as your trigger.
Then Zapier Webhook as your Action and set it to POST.
Add in your Bubble POST url to the workflow you want to run… (be careful to add version-test if you are in dev mode).
(I am passing the date in because my test API just a mandatory field, but you don’t need this).
The only slightly tricky bit is the authorisation, which you will need to put in the header as here…
