Parameters may be sent in any order.
gzip is enabled on all endpoints and is recommended to be used on the client side.
All endpoints are authenticated and require 3 mandatory parameters (uid, ts and sig). Details in the Endpoint security section.
Data is returned in descending order. Newest first, oldest last.
HTTP Return Codes
HTTP 200 API call was correct.
HTTP 4XX return code is used when the WAF (Web Application Firewall) has been violated.

Endpoints Limit

Rate and IP Limit

API endpoints calls are limited to 2 requests/second per IP address.
Surpassing the rate limit wil result in a 503 HTTP return code.
When a 503 is received, the caller needs to stop and not spam the API.
Repeated violation of the rate limit will result in an automatic IP ban.
The rate limit on the endpoints are based on the caller’s IP address and not the API endpoint.
Endpoints security

Authorized IP
Access to all endpoints is restricted to the predefined IP address(es) in your ZixiPay Wallet settings API Access Authorized IP.
User ID
All endpoints require parameter uid to be sent in the request body which is your ZixiPay Wallet User ID.
The uid is not case sensitive but needs to be sent in lower case.
Timestamp
All endpoints require parameter ts to be sent in the request body which is the Unix time when the request was created and sent.
API calls will be rejected if the ts is not within 60 seconds window from the endpoint server’s time.
Signature
All endpoints require parameter sig to be sent at the end of the request body.
Endpoints use HMAC-SHA256 signatures. The HMAC-SHA256 signature is a keyed HMAC-SHA256 operation. Use your ZixiPay Wallet API Access Key as the key and the request body as the value for the HMAC operation.
The sig is not case sensitive but needs to be sent in lower case.

Transactional Endpoints

withdraw

POST /apiv2/withdraw

Withdraw any of the supported cryptocurrencies.

This endpoint is used for sending funds to another wallet address on the blockchain.

A successful call to the withdraw endpoint, will create a pending transaction waiting in queue to be sent on the relevant blockchain which on average takes about 2-3 minutes. As soon as the transaction has been successfully sent on the relevant blockchain, the status of the transaction will change from pending to processed and the transaction id/hash will be added to the details of the transaction. In order to get the transaction hash/txid, simply call the statement endpoint with the ZixiPay’s transaction ID as the filter to get the details of the transaction in about 3 minutes after calling the withdraw endpoint.

Parameters:

Name	Type	Mandatory	Description
amount	decimal	YES	amount to be withdrawn
currency	string	YES	Any of the supported currencies (USDZ, EURZ, LTC, BTC, ETH, TRX, USDC or USDT)
recipient	string	YES	recipient’s wallet address (for USDT/USDC withdrawals: TRC20 or ERC20 addresses are acceptable)
feein	binary	NO	fee inclusive, deduct the fee from the withdrawal amount 0: (default) don’t deduct the fee from the withdrawal amount 1: deduct the fee from the withdrawal amount
uid	string	YES	User ID
ts	number	YES	Unix time
sig	string	YES	HMAC-SHA256 signature

IMPORTANT: If the feein parameter is set to 0 (default), a total of amount + the applicable fee would be deducted from the wallet.

Response: (Example)

{
  "result":"ok",
  "payload":[
    {
      "amount":"1500.00",           // amount of withdrawal
      "fee":"1.00",                 // processing fee
