Use Composable Workflows for new work. Existing legacy workflows can be migrated into Workflow V2 during the retirement period; migrated workflows preserve history and metadata where possible and are imported disabled by default so you can test before enabling them.
What a Composable Workflow Is
A composable workflow is a saved graph:- One trigger block starts the run.
- Data blocks fetch calls, transcripts, summaries, signals, search results, web pages, or HTTP responses.
- Logic blocks evaluate conditions, ask an LLM, format output, or roll up lists.
- Action blocks send webhooks, post to Slack, add calls to folders, or apply tags.
{{get_summary.summary}}, or a webhook body can combine a call title, transcript, and generated LLM answer.
How Runs Work
1
Trigger
A workflow starts from a call-completed event, extracted signals, a single signal, new feedback from a selected source, a manual run, a schedule, or a test run from the editor.
2
Resolve Inputs
BuildBetter resolves each block’s config from literals, upstream references, and template strings.
3
Execute Blocks
The engine runs the graph in dependency order. Condition blocks route only the matching branch.
4
Record Results
Each run stores a definition snapshot, trigger payload, per-node status, resolved config, output, errors, and timing.
Block Catalog
Triggers
Call Completed, Signals Extracted, Signal Created, Feedback Created, Manual Trigger, Schedule.
Data and Search
Get Call, Transcript, Summary, Signal, Participants, Call Signals, Search Calls, Search Signals, HTTP Request, Exa Search, Firecrawl Scrape.
Logic
Condition, Has Content, String Match, Ask LLM, Format Output, Format List.
Actions
Send Webhook, Send to Slack, Send Email, Add to Folder, Add Tag.
Common Patterns
Send a Call Summary to Slack
Use Call Completed -> Get Call Summary -> Send to Slack. The Slack block uses the connected Slack workspace and channel picker, so you do not need to build a webhook just to post a message.Route Feature Requests
Use Signals Extracted or Signal Created with Search Signals or Get Signal, optionally add a generated signal filter, then post a digest to Slack or send the payload to a webhook.Send Feedback to Slack
Use Feedback Created -> Format Output -> Send to Slack. The feedback-to-Slack template includes source details, content, timestamps, and related customer context.Email Internal Recipients
Use Send Email when a workflow should notify one or more active organization members. Email actions support Markdown-formatted bodies and attachments for rendered signals, signal lists, calls, or recordings.Create a Weekly Digest
Use Schedule -> Search Calls or Search Signals -> Format List -> Send to Slack or Send Webhook.Replace a Legacy Webhook Template
Start from a composable template such as Send Transcript to Webhook, Send Full Call Data to Webhook, or Conditional Summary to Webhook, then adjust the payload and conditions in the editor.Webhook Signing
Outbound workflow webhooks include BuildBetter signature headers when a signing secret is configured. Each webhook step can have its own secret, with copy and regenerate actions in the editor. Custom webhook headers cannot override reserved BuildBetter signature headers. Use the built-in verification guide in the webhook block for JavaScript and Python examples, or see API Webhooks.What’s New in v2
Multi-step graphs: Workflows are no longer limited to a single condition and action.
Scheduled workflows: Use a Schedule trigger with a cron expression and timezone.
Native Slack action: Pick a Slack channel directly from connected resources.
Run history: Inspect real and test runs with per-node details and errors.
AI-assisted editing: The workflow chat panel can build, edit, explain, and debug the current graph.
Getting Started
1
Open Workflows
Go to Workflows from the main navigation.
2
Create Composable
Choose a blank graph or start from a v2 template.
3
Build the Graph
Add a trigger, connect data and logic blocks, then add the final action.
4
Test Before Enabling
Use Test in the editor. Test runs execute real side effects, so point webhooks and Slack messages at safe destinations first.
5
Save and Enable
Save the graph, then turn on the Enabled switch when it is ready to run automatically.
