Creating workflows using the Zapier Workflow API is a recent addition, and there are some known limitations.
Zaps can only be created with Public Apps. Private Apps are not currently supported.
More complex Action types, such as Searches, Filters, and Paths, are not supported.
The API does not currently have an endpoint to turn off/on a user’s Zaps. If your Zapier app uses Webhook Subscriptions, you can send a DELETE to the unique target URL that was provided when the subscription was created and that will then pause/turn off a Zap.
Webhook READ actions are not currently supported.
If you’ve got a use case that you think should be supported, let us know!
