I'm trying to use an Outbound Message for the first time, as a trigger for Zapier (when a record is deleted, which isn't a native trigger in Zapier). I've created the 'New Outbound Message' listener in Zapier, and created the Outbound Message in Salesforce with the URL provided by Zapier. I then create my record-triggered flow, set my trigger parameters and try to add the Outbound Message Action, but it's not showing as an option to select. We're on the enterprise version of SF and I'm a system admin, so I'm not sure why I'm not seeing it. Any assistance would be much appreciated!
The reason is simply that Flow doesn’t surface it for delete triggers. Outbound Messages only show up in create/update record-triggered flows because that’s the part Salesforce moved over from Workflow. For deletes, Flow doesn’t support calling an Outbound Message at all, so the action won’t appear, no matter what permissions you have.
If you need Zapier to react to a deletion, you’ve got two realistic options: send an HTTP callout from a before-delete flow instead of using an Outbound Message, or create a temporary classic Workflow Rule on delete just to fire that Outbound Message to Zapier’s listener. Both approaches work, but the key point is that nothing is misconfigured on your end. Flow just doesn’t expose Outbound Messages for delete events.
