Validate a Turkish tax number

Checks the checksum of a Turkish tax number. An invalid number still returns 200. This does not query a tax office.

POST/v1/tr/tax-number/validate

import { Client } from "@liveapiio/liveapi";

const client = new Client({ token: process.env.LIVEAPI_TOKEN });

const tax = await client.validateTaxNumber("1234567890");

Request

Send Authorization: Bearer YOUR_TOKEN. The token stays on your server. Each library reads it from the environment and calls this endpoint for you.

Field	Type	Description
number	string	The tax number. Required.

Response

200 with valid: false means the checksum failed. That response still uses one call.

Errors

A failed request returns { "error": { "code", "message" } } and does not use a call.

Status	Code	When
400	invalid_request	A required field is missing or has the wrong type.
401	unauthorized	The bearer token is missing or not recognized.
