Send Typeform, Webflow or Gravity Forms leads to Master Inbox by webhook
Post any form's submission to a Master Inbox incoming webhook. It creates or updates the lead, maps each field to a custom variable, adds an Inbound label and alerts the team in Slack.

Why teams run it
Forms from any site land next to your outbound conversations, with the same follow-up.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Send Typeform, Webflow or Gravity Forms leads to Master Inbox by webhook.
- Set the trigger to Incoming Webhook and choose Your form tool, or Zapier, posts the submission JSON.
- Add the action Add labels: Inbound.
- Add the action Notify in Slack: Post the form answers and thread link to #inbound.
- Save the workflow and switch it to Active.
Before you start, connect Slack under Settings, Integrations.
Sending data in from another tool
The Incoming Webhook trigger is set up in the app: Master Inbox gives the workflow its own URL, you send one sample payload from your tool, then map its keys to prospect fields. After that, your tool posts to that URL and the workflow runs. Everything else in the workflow is also in the API.
Reference: workflow API guide.
Questions
How do I map the form fields?
In the app, generate the workflow's URL, send one sample payload and map each key to a lead field or custom variable.
Will the AI labeler still label the lead?
AI labeling skips leads that already have a label, so drop the Inbound label if you want AI labels on these leads.
Which plan includes this?
This workflow works on the Revenue plan. Every plan has unlimited users and starts with a free 7-day POC.
