How to Use Postbox with OpenClaw: Agent Native Data Collection

Setting Up Your API Key

Before installing the skill, set your Postbox API key as an environment variable to your OpenClaw’s environment configuration at ~/.openclaw/.env:

echo "POSTBOX_API_KEY=your_api_key_here" >> ~/.openclaw/.env

Never commit your API key to source control.

Installing the Postbox Skill

Getting started takes seconds. Install the Postbox skill using the OpenClaw CLI:

openclaw skills install postbox

That’s it. Your OpenClaw agents now have built-in tools for working with Postbox.

A Practical Workflow

Here’s how you might use this:

1. Create a Postbox form for bug reports (title, description, severity, steps to reproduce the bug, etc.)
2. Copy the endpoint URL Postbox handles this for you! your openclaw automatically gets the endpoint url from the form creation step!
3. Share the URL via a form, or just the url to other agents, and since the endpoint is self documenting, you don’t even need a UI!
4. Process the submissions using OpenClaw just ask openclaw to list/get/translate/reply to submissions! and much more!

OpenClaw will:

• GET the endpoint to discover the schema
• See which fields are required
• Construct a valid payload
• POST to the endpoint
• Handle any validation errors by correcting and retrying
• Return the submission confirmation

This works for any type of form - feedback surveys, lead capture, customer support, whatever data you need to collect.

Here’s what it looks like in action:

Using OpenClaw Commands

You can also create custom OpenClaw commands for frequently used tasks. Add a command file in your project’s .openclaw/commands/ directory:

---
description: Submit a bug report to Postbox
agent: build
---

Submit a bug report to our Postbox endpoint. First, GET the endpoint to discover the schema, then construct a valid payload with the bug details I provide, and POST it. If validation fails, fix the errors and retry.

Now typing /bug-report in OpenClaw gives you a reusable command for submitting bugs.

How It Works

Here’s what happens when your OpenClaw agent needs to submit data:

1. Agent GETs the endpoint with Accept: application/json
2. Postbox returns the schema - field names, types, required flags
3. Agent constructs the payload - builds valid JSON from the schema
4. Agent POSTs the data - same endpoint, different method
5. Postbox validates - returns 201 on success, or structured errors

The agent handles everything. You just provide the endpoint URL.

Get Started

Create an account at usepostbox.com, set up a form, install the Postbox skill, and give the endpoint URL to OpenClaw. That’s the entire integration. Your coding harness handles the rest - schema discovery, payload construction, error handling, all automatically.

Give OpenClaw a URL, and let the agent do the rest.
