Human in the Loop

Human in the Loop Wrk Actions pause a Wrkflow so a person can review, approve, or submit information before automation continues. User Form Wrk Actions are Wrk's built-in mechanism for steps that need human judgment.

What it is

A User Form Wrk Action generates a shareable link. When someone opens the link and submits the form, the Wrkflow resumes with their response. Pair a create form Action with a wait for response Action to hold the Launch until input arrives.

Good for

• Approval workflows (yes/no decisions with optional comments)
• Collecting structured input from a teammate or customer mid-Launch
• Reviewing AI or RPA output before the next automated step executes
• High-stakes decisions where a person must sign off (payments, compliance, customer communication)

What it does

• Simple approval forms: create a yes/no form with optional freeform text and an optional attached file
• Custom forms: build forms with HTML fields (text, select, radio, checkbox, file upload) and capture responses as JSON
• Wait for response: pause the Wrkflow until the form is submitted or a timeout is reached
• Branch on outcome: route the Wrkflow differently based on approval (yes/no) or custom field values
