Trigger Workflow A from Workflow B

I have faced this sort of hurdle already and it is frustrating to say the least.

The limiting factors are usually:

• no ‘foreach’ loop being available in Workflows
• the inability to get the information you need via the API, expressions or the like (info is in the GUI only)
• Workflows can not be triggered on Ticket updates made by other Workflows (by System)

Perhaps give this one an upvote ​@SnuffleRoe ; it is the major part of the puzzle that will unlock this functionality for you:

Also, I have been advised at some stage that an ‘Approval Engine’ is in the works which might allow for a more conditional and expansive Approval Workflow but I am not aware whether this will cover just Changes or whether it will also be available for Ticket Approval Workflows

Thank you for your reply ​@MDavies. I just upvoted that idea.

I hope that Apporval engine won’t just be for Changes as I have the Growth subscription which doesn’t include Changes.

A native solution would be best, but there are a few different ways to achieve a similar workflow. You could for example create a workflow that triggers on ticket update and executes on tickets tagged with “pending approval” for example, so one workflow would run based on your criteria and add that tag, and the approval workflow would then be triggered (and then change/remove the tag to prevent repeated execution).
