I have around 50+ workflows rules in our org. And there may be around 5 to 10 rules which Have time dependent workflow actions. How can I easily identify which workflow rule has one?
Currently both tooling API & Meta data API do not provide details about Workflow Queue object where information about time dependent workflow is stored.
So there there is no legitimate way by which you can do this. But there is workaround that you can use.
You can set naming convention where all time dependent workflows must start with name "Time_XXXXX" using any of above api you can get the list of all workflows and search for "Time_" sting in name field.
The other work around is screen scrape Salesforce with REST GET call from Apex which not recommended.
