Hi Michael,
To set up a webhook, first, you need to subscribe to a webhook platform. Use a free one here, you do not need any advanced functionality. Look into BrightHooks, Hoosh or Flowboost.
Once you have the subscription, you will have also the instructions on how to set this up in Marketo admin.
Finally, you will have to call the webhook from a smart campaign as explained in the doc : Use a Webhook in a Smart Campaign - Marketo Docs - Product Documentation
Now, for a specific birthday, you can still use simple smart campaigns.
create a smart list of every one who is above 18 or has no birth date (they will be excluded) :
And another one of every one who is below 17 and 11 months (they will be excluded as well)
Then create a smart campaign that run once for every one with a wait until the birthdate:
Smart list :
first flow step, using an advanced wait:
Make sure that people can only enter the smart campaign once :
Schedule your campaign to run every day.

Why not
?
I'm not so into have hundreds of thousands of leads in waits.
(And I say this as the author of one of those webhook platforms!)
