Features

Everything you need to understand why your HubSpot workflows aren't working as expected.

Checkpoint Logging

Capture workflow state at critical points: enrollment, branch decisions, and action execution. Know exactly what data was evaluated at each step.

  • •START checkpoint captures workflow entry
  • •BRANCH checkpoint records condition evaluation
  • •ACTION checkpoint logs before key operations
  • •Includes timestamps, property values, and results

Branch Tracing

Visualize exactly which path your workflow took and understand why. See condition evaluations with actual vs expected values.

  • •Records which branch path was taken
  • •Shows condition property, operator, and expected value
  • •Displays actual value at time of evaluation
  • •Identifies exactly where workflows diverge

Smart Explanations

Get plain-English explanations of why your workflow didn't do what you expected, complete with evidence and actionable fix suggestions.

  • •Clear summary of what happened
  • •Most likely cause identification
  • •Supporting evidence from logs
  • •Actionable fix suggestions

Real-Time Monitoring

Watch your workflows execute in real-time. Logs are captured as each checkpoint is reached, giving you instant visibility.

  • •Logs captured instantly via webhook
  • •No polling or delays
  • •Secure HMAC signature validation
  • •Lightweight impact on workflow execution

HubSpot CRM Integration

Automatically fetches deal data from HubSpot to provide richer context in explanations. Understands your CRM state.

  • •Fetches deal properties automatically
  • •Uses HubSpot Private App authentication
  • •Correlates CRM data with checkpoint logs
  • •Works even without CRM access (logs-only mode)

Rule-Based Analysis

Fast, deterministic analysis using pattern matching on checkpoint logs. Identifies common workflow issues instantly.

  • •Detects missing checkpoints
  • •Identifies failed branch conditions
  • •Spots action execution errors
  • •Recognizes incomplete workflow runs

Common Use Cases

Real scenarios where FlowLens helps you quickly identify and fix workflow issues.

"Why didn't this deal get a task?"

A sales rep expected a follow-up task to be created when a deal moved to a certain stage, but it never appeared.

FlowLens insight: FlowLens shows that the branch condition checked for amount > $10,000, but the deal was only $8,500.

"The email never sent"

An internal notification email should have been sent when a deal closed, but no one received it.

FlowLens insight: FlowLens reveals the workflow started but exited early because the deal owner field was empty.

"Wrong path taken"

A deal went through the wrong workflow branch and received incorrect automation.

FlowLens insight: FlowLens traces the exact branch path and shows which condition evaluated differently than expected.
