Order signature exchange

Budget: 3000 UAH Deadline: 2 days

Good day! I write Python scripts for exchange APIs — placing orders via REST and signing requests I have done more than once. The task is clear, I will complete it in a day. Please let me know which exchange and whether the order is spot or futures — this affects the signature and method.

Volodymyr, I will help you create a Python script that will correctly connect to the exchange using your API data and wallet and will place 1 test order. Usually, I first check the signature format, nonce/timestamp, and the correctness of the endpoints to avoid authorization errors. I have worked with API integrations in PHP and JS, so I will carefully bring it to a working result and, if needed, explain how to run and check the request.

Good day.

The Python category is indicated absolutely correctly. This language is the best suited for interacting with trading platforms.

I specialize in creating automation scripts for data processing in Python. I will write reliable code for successfully placing your test order. I will set up secure authorization through your API keys, implement the correct algorithm for cryptographic signing of the transaction using a wallet, and send the prepared request to the exchange server. The code will definitely include handling server responses for accurate understanding of the order status.

Please write the name of your exchange in private messages. The choice of necessary libraries and the exact format of request signing depends on the platform.

Hello, I have worked on a similar project — integration with the Binance exchange via API, where I implemented automatic order placement with request signing (HMAC SHA256). We processed ~500 orders/day with 99.8% accuracy ✅

Do you need a script for spot trading or for futures — and which exchange is being used?

I suggest we connect; I will provide you with free technical consultation and we can outline a development plan + I will tell you about my team!

Budget: 2500 UAH Deadline: 1 day

I will create a Python script that will connect to your account and send the first order.

The authorization and request signing mechanics are the same for most exchanges, so this is a quick task.

I write such scripts for my own trading on Hyperliquid; authentication and request signing are familiar work for me.

If further actions are needed afterward, I will assist and provide a short guide on how to replicate or expand the script independently.

We will discuss the details in the chat.

Budget: 2500 UAH Deadline: 1 day

I understand the task: a Python script that places a test order on the exchange using your API keys — request signing, authentication, sending the order, and confirming that it has been accepted.

I have been working with crypto exchange APIs for a long time — Binance, Bybit, Huobi, KuCoin, trading bots, and desktop terminals. Request signing (HMAC or similar depending on the exchange) and working with orders is a standard part of such projects.

Please specify which exchange and type of order — spot, margin, or futures, market or limit. This affects the specific endpoint and signature format, but the mechanics are identical across all exchanges I have worked with.

Hello, Vladimir! I have reviewed the task. I am ready to promptly write a clean and secure Python script for successfully placing a test order.

I will implement the project in Python 3.12 using your API data:
1. I will move all authorization keys to secure environment variables (.env) so that they are strictly stored on your side.
2. I will implement the correct formation of the cryptographic signature of the request (hashing, timestamp, nonce) strictly according to your exchange's documentation.
3. I will set up a clear output of the server's response in the console so that you can immediately see the order status or error message.

I have extensive experience in automating scripts and working with APIs. The code will be neat, accompanied by comments and a simple instruction for running it.

Could you please let me know which exchange we will be working with and which network/platform wallet is being used?

Good day!

I am interested in your project. I have experience in developing Python scripts for working with REST APIs, authentication, cryptographic signatures, and integrations with external services.

I can implement a script that correctly passes authorization, generates the necessary request signature, and successfully places a test order according to the exchange's API requirements. During development, I pay attention to error handling, logging, and a clear code structure so that it can be easily extended in the future.

Upon completion, you will receive a ready Python script with a brief instruction on how to run and configure it.

I am ready to familiarize myself with the API documentation and start working immediately.

I look forward to collaborating! Expand

Hello!
My name is [Name], and I am a Fullstack developer with expertise in UI/UX design and over 3 years of experience in web development. My experience combines both freelance practice and training in an in-house IT company, so I clearly understand what team deadlines, project architecture, and a product-oriented approach entail.
My main advantage is that I can handle tasks "turnkey" and see the product holistically:
Design and UX: I create modern, clean, and user-oriented interfaces.
Frontend & Layout: I cleanly translate designs into code using JavaScript, HTML5, and CSS3 (of course, with responsiveness for any screens).
Backend: I implement stable logic and integrations in Python or Java.
Testing (QA): Thanks to my experience in testing, I write code that is easy to verify and independently find bugs before the project reaches the end user.
I am very open to communication: always available, ready for constructive calls, discussing specifications, and justifying technical solutions. It is important for me not just to "write code," but to create a product that solves your business's task.
I would be happy to discuss the project or job details at a time convenient for you!

Hello! I am ready to quickly write a clean Python script for you to place a test order. I will implement everything using the official CCXT library (suitable for any exchange: Binance, Bybit, OKX, etc.) or using pure requests for a specific API. We will store the keys in secure environment variables, set up logging for responses from the exchange, and handle errors (if there is insufficient balance or incorrect keys).

Hello, Vladimir! My name is Nina, I am a manager. My Python developer will quickly solve your task. He regularly works with cryptocurrency exchange APIs and knows how to properly assemble and sign requests so that the exchange does not reject them due to timeout or authorization error.

What he will do:
He will connect your API keys through secure environment variables (.env) to avoid exposing them in the code.
He will set up the generation of the correct digital signature (hashing parameters, nonce/timestamp).
He will write a clean script to send one test limit or market order.
He will output a clear response from the exchange to the console (success/error text).
We will do everything using the standard requests library or ccxt (depending on the specific exchange). We will deliver the finished script today. Please message me privately about which exchange it is?

Cost: 2500 UAH
Deadline: 1 day (we will complete it in a couple of hours after clarifying the exchange) Expand

Good day.

I can implement a Python script that will generate the correct request signature according to your exchange's documentation, use the provided API data and wallet, and successfully place a test order. I can also explain the difference between order types if needed.

Before starting, I just need to clarify three points: which exchange is being used, what type of order needs to be created, and whether this is a test environment or a real account. This is important because each exchange has its own signature algorithm and API format.

As a result, you will receive a ready-to-use script that can be run repeatedly, with minimal configuration and a clear code structure.

To start, I will check the authorization through your API data for free and confirm that the signature is being formed correctly. If everything works as needed, I will complete the implementation of placing the test order.

The budget is 2500 UAH. I can start immediately after receiving the API key and the name of the exchange. Expand

Hello.
I have reviewed your requirements.
I would like to continue the discussion to confirm your specific needs.

Budget: 2500 UAH Deadline: 1 day

Hello! The task is clear, the script can be written quickly, but to provide an accurate estimate, I need to clarify a few technical details:

- Which exchange is planned for work?
- Which section: spot market or futures (derivatives)?
- Where will we conduct the test: in the test network (Testnet) or on a real account with a minimal volume (Mainnet)?
- By "wallet," do you mean the balance on the exchange (CEX) or an external Web3 wallet (Metamask, Trust Wallet, etc.)?
- What type of order needs to be tested (Market at the current price or Limit)?

Once we clarify these points, I will provide information on timelines and costs.

Volodymyr, you need to automate the order signing process for successful interaction with the exchange's API through Python. The main difficulty here lies in correctly forming the request considering the signature that the server requires for transaction authorization. I will analyze your exchange's documentation, set up the library to work with the API, and implement a script that correctly signs and sends a test order. Please let me know if you already have the API documentation ready for signing requests or if I will need to rely on existing public examples.
