Katixo API

Build integrations with Katixo's accounting, invoicing, inventory, and GST compliance platform. The API follows REST conventions, uses JSON for all request and response bodies, and authenticates via JWT Bearer tokens.

Base URL

https://api.katixo.com/api/v1

All API requests must be made over HTTPS. HTTP requests are rejected.

Quick start

curl https://api.katixo.com/api/v1/invoices \
  -H "Authorization: Bearer eyJhbGciOiJIUzI1NiIs..." \
  -H "Content-Type: application/json"

This returns a paginated list of your invoices. See Authentication for details on obtaining and refreshing tokens.

Response format

All API responses are wrapped in a standard ApiResponse envelope:

{
  "success": true,
  "message": "Invoices retrieved successfully",
  "data": { ... },
  "errors": null
}

On error, success is false and the errors field contains validation details:

{
  "success": false,
  "message": "Validation failed",
  "data": null,
  "errors": {
    "invoiceDate": "must not be null",
    "contactId": "must not be null"
  }
}
