Send a LinkedIn connection request after an unanswered call

When a rep labels a thread Call: no answer, Master Inbox adds the lead to a HeyReach campaign that sends a connection request with a tried to call you note.

When

Add LabelCall: no answer

Then

Add to HeyReach campaignTried to call you campaign

Why teams run it

Email, phone and LinkedIn work as one cadence instead of three.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.
Name it Send a LinkedIn connection request after an unanswered call.
Set the trigger to Add Label and choose Call: no answer.
Add the action Add to HeyReach campaign: Tried to call you campaign.
Save the workflow and switch it to Active.

Before you start, connect HeyReach 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": "Send a LinkedIn connection request after an unanswered call",
  "trigger_type": "add_label",
  "trigger_config": {
    "label_ids": [
      176479
    ]
  },
  "action_configs": [
    {
      "action_type": "add_to_sequence_heyreach",
      "campaign_ids": [
        "camp-1"
      ]
    }
  ]
}'

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: "Send a LinkedIn connection request after an unanswered call". 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 the dialer set the label?

Yes. Post the call outcome to an Incoming Webhook workflow, or have the rep label it.

Can I also email them?

Yes. Add your sequencer's add to campaign action to the same workflow.

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 Team plan. Every plan has unlimited users and starts with a free 7-day POC.
