ClientCasa Developer Platform

Build invoicing, CRM, scheduling, and payments into your product with a small, type-safe REST API and an official TypeScript SDK.

Quick start

import { ClientCasa } from '@clientcasa/sdk'

const cc = new ClientCasa()
const security = { apiKey: process.env.CLIENTCASA_API_KEY ?? '' }

const result = await cc.clients.listClients(security, { pageSize: 25 })
for (const client of result.data) {
  console.log(client.name, client.status)
}

await cc.invoices.createInvoice(security, {
  clientId: result.data[0]!.id,
  issueDate: '2026-05-19',
  dueDate: '2026-06-18',
  lineItems: [
    { description: 'Strategy consult', quantity: 4, unitPrice: 250, taxable: false },
  ],
})

# Install nothing. Hit the API directly.
curl -s "https://www.clientcasa.com/api/v1/clients?pageSize=25" \
  -H "x-api-key: $CLIENTCASA_API_KEY" \
  | jq '.data[] | { name, status }'

# Create an invoice
curl -s "https://www.clientcasa.com/api/v1/invoices" \
  -X POST \
  -H "x-api-key: $CLIENTCASA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "clientId": "<id>",
    "issueDate": "2026-05-19",
    "dueDate": "2026-06-18",
    "lineItems": [
      { "description": "Strategy consult", "quantity": 4, "unitPrice": 250, "taxable": false }
    ]
  }'

Get an API key at Settings → Advanced → API Keys. For partner apps acting on behalf of users, register an OAuth app under Settings → Advanced → OAuth Apps instead.

Resources

Seventeen first-class resources covering the full business cycle. Most follow the same shape — list / create / get / update / delete — with offset pagination (page / pageSize), typed errors, and OpenAPI-driven SDK methods. A few are read-only where the underlying record is built elsewhere (Payouts come from Stripe; Forms, Form Submissions, Document Versions, and Client Documents are composer- or platform-built), and Payments omits delete because money events are immutable. (Leads aren't a separate resource — a lead is a client at an early lifecycle stage, so fetch them via /v1/clients?status=new|contacted|qualified.)
