AppFolio Hello World

Overview

Get started with the AppFolio Property Manager API by authenticating with your client credentials and making your first API calls. This skill walks through connecting to the REST API, fetching a property listing, retrieving tenant details, and creating a basic work order — the essential operations for any AppFolio integration.

Prerequisites

• AppFolio Stack Partner account with API access
• APPFOLIO_CLIENT_ID and APPFOLIO_CLIENT_SECRET environment variables set
• Node.js 18+ and TypeScript

Instructions

Step 1: Configure the Client

const APPFOLIO_BASE = process.env.APPFOLIO_BASE_URL || "https://yourcompany.appfolio.com/api/v1";

async function appfolioFetch(path: string) {
  const credentials = Buffer.from(
    `${process.env.APPFOLIO_CLIENT_ID}:${process.env.APPFOLIO_CLIENT_SECRET}`
  ).toString("base64");
  const res = await fetch(`${APPFOLIO_BASE}${path}`, {
    headers: { Authorization: `Basic ${credentials}`, Accept: "application/json" },
  });
  if (!res.ok) throw new Error(`AppFolio ${res.status}: ${await res.text()}`);
  return res.json();
}

Step 2: List Properties

const properties = await appfolioFetch("/properties?page_size=10");
console.log(`Found ${properties.length} properties`);
properties.forEach((p: any) => console.log(`  ${p.id}: ${p.address_line1}, ${p.city}`));

Step 3: Get Tenant Details

const tenants = await appfolioFetch(`/tenants?property_id=${properties[0].id}`);
tenants.forEach((t: any) => console.log(`  ${t.name} — Unit ${t.unit_number}`));

Step 4: Create a Work Order

const workOrder = await fetch(`${APPFOLIO_BASE}/work_orders`, {
  method: "POST",
  headers: {
    Authorization: `Basic ${Buffer.from(`${process.env.APPFOLIO_CLIENT_ID}:${process.env.APPFOLIO_CLIENT_SECRET}`).toString("base64")}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    property_id: properties[0].id,
    description: "Leaky faucet in kitchen",
    priority: "normal",
  }),
});
console.log("Work order created:", (await workOrder.json()).id);

Output

A successful run produces authenticated API responses: a list of properties with addresses, tenant details for the first property, and a new work order ID confirming write access.
