# Messaging & notifications

> Steps that call external systems or notify your team about contacts and companies in a workflow

Use these steps to reach outside the workflow — calling another system over HTTP, or notifying your team in Enginy or Slack about a contact or company.

  Send HTTP request

Calls an external API or webhook — Zapier, n8n, Slack, or your own backend — with a templated URL and JSON body. One request is sent per contact or company that reaches this step.

Use it as an extensibility point for anything Enginy doesn't natively support: triggering an automation, logging to an internal system, or notifying a tool outside Enginy.

**Settings**

| Setting | Required | What it controls                                                            |
| ------- | -------- | --------------------------------------------------------------------------- |
| Method  | Yes      | The HTTP method used for the request (defaults to POST).                    |
| URL     | Yes      | The request URL. Supports templated fields resolved per contact or company. |
| Headers | No       | Custom headers sent with the request.                                       |
| Body    | No       | The JSON body sent with the request, templated per contact or company.      |

**Output**: the same contact or company, unchanged — the step continues regardless of the response it gets back.

Posts a message to a Slack channel for each contact, with contact variables, optional teammate mentions, and a link back to the contact in Enginy.

Use it to alert your team in Slack as contacts reach a certain point in the workflow.

**Settings**

| Mention teammates | No       | Teammates to @mention in the message.                 |

**Output**: the contact, continuing to the next step.
