Create a HubSpot contact for every website form lead

When a website form submission arrives with its form label, Master Inbox creates or updates the HubSpot contact and company, with the conversation attached.

Why teams run it

Inbound leads reach the CRM at once, with the form answers on the record.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.
Name it Create a HubSpot contact for every website form lead.
Set the trigger to Add Label and choose Website form.
Add the action Sync to HubSpot: Upsert the contact and company and attach the thread.
Save the workflow and switch it to Active.

Before you start, connect HubSpot under Settings, Integrations.

Or create it with the API

Everything in the workflow builder is also in the Master Inbox API. This request creates the same workflow. Replace the example ids with your own label, list and campaign ids from GET /workflows/filter-fields.

curl -X POST https://api.masterinbox.com/api/api-webhook/v1/api/workflows/create-workflow \
  -H "Authorization: Bearer $MASTER_INBOX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "name": "Create a HubSpot contact for every website form lead",
  "trigger_type": "add_label",
  "trigger_config": {
    "label_ids": [
      176479
    ]
  },
  "action_configs": [
    {
      "action_type": "sync_to_hubspot"
    }
  ]
}'

Or ask Claude, ChatGPT or Grok to build it

Our workflow guide is written for AI agents to read. Give your assistant your API key and this prompt:

Read https://app.masterinbox.com/public-workflow-api.md and use my Master Inbox API key to create this workflow: "Create a HubSpot contact for every website form lead". First call GET /workflows/filter-fields and look up my label, list and channel ids, then create the workflow and tell me what you set up.

Questions

Can I create a deal too?

Yes. Map the Website form label to a deal pipeline and stage in the HubSpot integration.

Can I track ad conversions from the form?

Yes. Forms have fields for the Meta pixel, Google tag and Google Tag Manager.

Can I build this workflow through the API?

Yes. Send the create-workflow request shown on this page with your Master Inbox API key. The API checks the payload first and lists every problem by field if anything is off.

Which plan includes this?

This workflow works on the Revenue plan. Every plan has unlimited users and starts with a free 7-day POC.
