`password`	string	Yes	Your API secret.

Request example

curl --request POST \
--url [base]/token/ \
--header 'Content-Type: application/vnd.api+json' \
--data '{
  "data": {
    "type": "auth-token",

}

requests.post(url, headers=headers, json=data)

<?php

use GuzzleHttp\Client;
use GuzzleHttp\Exception\RequestException;

$client = new GuzzleHttp\Client();
try {
  $res = $client->post('[base]/token/', [
    'json' => [

Response

Name	Type	Description
`access`	string	Your access token. It has an expiry time of about a minute and after expiration should be refreshed.
`refresh`	string	The long-living token that is used for obtaining new access tokens (refer to Refresh token).
`access_expired_at`	string	The date and time of access token expiration.
`refresh_expired_at`	string	The date and time of refresh token expiration.
`is_2fa_confirmed`	boolean	If `true`, 2FA is enabled. 2FA is unavailable for API users.
`time`	string	The date and time of request receiving.
`sign`	string	The HMAC signature for a response payload authentication. To verify that the refresh token was sent by Coinsbuy, generate an HMAC signature using the `sha256` as algorithm: `sha256` hash of the concatenation of your login and password as a key, and the concatenation of `meta.time` and `refresh` fields as a message. Refer to Auth verification below for a sign verification example.

Response codes

HTTP code	Application code	Description	Suggested action
`200`	—	OK	—
`400`	2006: No active account found with the given credentials	Incorrect credentials	Send correct credentials.
`429`	throttled: Request was throttled	Too many requests	Try again later.
`500`	—	Internal server error	Try again later.
`502`	—	Bad gateway	Try again later.
`503`	—	Service unavailable	Try again later.
`504`	—	Gateway timeout	Try again later.
`5xx`	—	Other server errors	Try again later.

Once you receive a new key pair using your refresh token, the previous refresh token can no longer be used. A refresh token that is found to be invalid while not being expired must be rendered suspicious.

Request

POST [base]/token/refresh/
