Thanks for the api docs, could you please provide example on how to get nonce and v,r,s values. Thanks!

const salted = hashPersonalMessage(toBuffer(raw))
const {
v,
r,
s
} = mapValues(ecsign(salted, privateKeyBuffer), (value, key) => key === 'v' ? value : bufferToHex(value));
// send v, r, s values in payload

Im trying to fetch some orderbook updates, But only received newTrade data.

trying to use the websockets, but its not working

As per documentation, if market parameter omitted the entire orderbook returned by market key. When I omit I get error "Must specify a market". So any way to get whole orderbook? Or fix documentation.

lowestAsk and highestBid from ticker return not current lowest ask and highest bid as in most of all exchanges but seems like lowest and highest for 24 hr. Is it correct behaviour? It is more useful to have current values.

when using the returnTradeHistory with an address parameter. Result "type" is always set to "buy" even if its a sell.

Because of CF

Dear all devs,

When I place an order, sometimes successfully, sometimes failed with error:
Invalid payload (HTTP status code: 400)

Could you please give me an idea to fix this issue?

Thanks and best regards,

I'm using v2 WS API for orderbook syncing. I've stored each cancel from pushCancel and pushCancels messages using their ID as key in DB. But as i see, sometimes cancel is missed. For example, after cancel { "id": 38795396, ... } next is { "id": 38795398, ... } , but 38795397 is missed. I have tried to listen WS api parallel on 2 different machines, and both of them has same missed cancels.

I send this object to your API

Whats wrong I do? Sing code is from your example

Hi All,

Anybody knows how make transferring coins via API? does such-like function exist ?
And how to deposit coins from the Wallet to IDEX?

Pls kindly help)

This API call is returning an empty dictionary, is it just me?

Send "trade" request
Get error:
{
"error": "ER_PARSE_ERROR: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ') FOR UPDATE' at line 1"
}

or sometimes

}

Even if I send all post data. I get same error

Hi,

While using the 'trade' api many times the order is not fulfilled as the order for which it was signed is no longer valid or is partially filled and the returns 400 status code.
As the string may change I don't want to rely upon it can we have error code to sent in the apis too as a improvement?

Example response:

{
    "error": "The order you are trying to match has been partially or fully matched. Please refresh to clear it from the orderbook."
}
and
{
    "error": "Order no longer available."
}

When I tried to call returnOpenOrders aka https://api.idex.market/returnOpenOrders/ETH_SNT

I got

{
    "message": "Missing Authentication Token"
}

However, nowhere in the docs is it explain how to get an authentication token or where to put it. Can someone help?

For example returnNextNonce returns { nonce: 10 }. Then I try to place new order with nonce: 20. Why it returns the error "Nonce too low. Please refresh and try again."?
I tried to calculate nonce from current time, but the other issue appears.

Hello, returnTicker endpoint is returning {lowestAsk: "N/A", highestBid: "N/A"} for all currencies.

In this image you can see that we get N/A for ELEC

And it's like that for all currencies:

I am integrating IDEX API into one of our clients. We are implemented related API's but I've some questions

1. How can I check order executed or not any event is there.

2. How can I listen to only one currency pair instead of all pair's? (Very important, because we want to do trade for only one currency, this will save resources)

3. What is the difference between trade and order API, can you explain in detail with an example.

4. Can you please provide ropsten / rinkeby test IDEX implementation, this will save real ethers.

When I tried to use endpoint returnNextNonce, I got an error {"result":"error","errors":["[LAMBDA-RUNNER]\n FAILED TO INITIALIZE LAMBDA! \n \n Our initialization function expects either one or two arguments, however, \n you provided 3 parameters.","Cannot set property 'agent' of undefined"]}.
A few days ago all was working.
Use API https://api.idex.market

Each Query through to (https://api.idex.market or https://api-regional.idex.market) will retrun a html document where is CAPTCHA required

Greetings.

Please help for us.

When I place the order I always get '.. nonce: 0 ..' in the output. Why?

I've tested my algorithm by example you've given at #26. The result is perfect match to your r, s, v values. However the error "Invalid order signature" still appears (not always but sometimes). As well as "Invalid cancel signature"

Due to not working API returnNextNonce method, i decided to use a very big random nonce. Then i finally placed order with an API, but now i even can't trade or withdraw on the site, cuz i changed nonce manually. Now when im tryna withdraw funds or place an order, a "nonce too low" error appears in a little window on site. API withdrawal doesnt work too says either nonce too low or Invalid signature. Thus, my funds r blocked, i cant do anything with my money!!! So when will u fix next nonce method or is it possible to reset nonce for my address or at least withdraw my funds? Or how do the site get the nonce? I checked its network activity, there's nothing like nonce. Or how do nonce generates? I wrote to the support in telegram, but they dont understand what im talking about, they think i just have an issue with nonce and cant use API, but i cant use ANYTHING now :(

how to create a sell order by using api ?

const raw = soliditySha3({
t: 'bytes32',
v: args.orderHash
}, {
t: 'uint256',
v: args.nonce
});
const salted = hashPersonalMessage(toBuffer(raw));
const vrs = mapValues(ecsign(salted, toBuffer('private_key')), (value, key) => key === 'v' ? value : bufferToHex(value));

const args2 = Object.assign(args, vrs);
response.end(JSON.stringify(args2))

What's wrong?

Are you going to update any of you websocket API documentation? There's nothing indicating what data is available. At this point the only thing returnable is the message stating that the subscribe is a success.

When I am trying to sell / buy more than 1000 tokens it says Invalid payload, seems some issue with API function parameters(overflow?).

Please advise.

{
"market" : "ETH_ELEC"
}
returns
{
"error": "Market ETH_ELEC not found"
}

Another function openorders returns
"error": "Cannot read property 'toLowerCase' of undefined"

Is this web API working properly or is this in maintenance mode?

address I'm not change before.
but today I have some error in line lib/python3.5/site-packages/idex/client.py", line 170, in set_wallet_address

{"error":"Invalid order signature. Please try again."}

What's wrong with order signature? What v, r, s parameters values should be in this case? Please, help!

Hi,

I am trying to retrieve the ask and bids data using the api but it is not working.

When I do it through returnTicker, the ask and bids fields are always N/A. When I do it through returnOrderBook, it returns an empty object when no JSON is specified and when I specify a JSON, it returns that the market can't be found.

Could someone look into this please!

Hi,
I'm trying to establish a reliable connection to the v1 websocket api,
I'm able to connect and perform the handshake correctly, I get a response like

{"sid":"XXXXXXX","result":"success","format":"json","method":"handshake","payload":{}}

after that one I start receiving the correct data, but after a couple o seconds the server closes the socket connection with reason: 412, Session ID Mismatch.

any idea why? Should I use the sid parameter received after the handshake request? If yes how?

Thank you

It seems that there is a bug in the "returnTradeHistory" API. The "type" field is always filled with "buy" value, even when the order is a sell order... So how to differentiate a buy and sell order in the returned history?

when we query for all possible tickers we get this kind of response but here we don`t have any key associated with names like no key is associated with ETH_SAN value, could you please tell me how we are suppose to extract name from this object i am using nodejs.
