Questions And Answers

This is the Q&A section. If you cannot find answer to your question, please join us Telegram API Group in time.

APIKey Q&A

1. How to apply for APIKEY?

API application site: https://www.bitmart.com/open-api-guide/en-US

After successful application on the website, please keep your access key, secret key and memo.

2. Can I retrieve the secret key of API KEY?

No, you will need to create new APIKEY.

3. Is there any risk of authorizing API KEY to a third party?

This will create some risk, and it is recommended to keep it yourself for account security.

4. Can I apply for API KEY without binding my phone or Google?

No, you must bind more than 2 security items to apply for API KEY.

5. When creating an API KEY, do I have to bind an IP address?

It is not necessary. The option to bind IP when applying for API KEY is optional, but in order to increase the security of user accounts, it is recommended to bind the IP address.

6. Will different API KEY in the same account return different data?

Different API KEY data under the same account is the same.

7. How many API KEY can I apply for in one account?

Each account can create 5 sets of Api Keys, and each Api Key can be set correspondingly to various combination permissions such as cash Withdraw, Spot-trade, and Contract-trade.

8. How to fill information in when applying for APIKEY?

Fill in according to the prompt on the web page, and the memo can be filled in at will by the user; the secret key must be remembered, and it will be used when calling the API interface; binding IP is not required, but it is recommended for account security; API permissions can be checked based on user needs.

9. What is memo?

Memo is provided by users themselves. It will be used in the signing of the interface.

Authentication Q&A

1. What is the maximum difference between the timestamp parameter of the request interface and the time to reach the server?

Requests that differ by more than 1 minute between the timestamp and the API server time will be considered expired by the system and rejected. If there is a large time deviation between the user server and the API server, it is recommended that the user use the "Get Server Time" interface to query the API server time.

2. How to solve error "The request header "X-BM-TIMESTAMP" cannot be empty", which occurs from time to time?

First of all, it is recommended that the user print out whether the request header parameter X-BM-TIMESTAMP has a value. In addition, it is recommended that the user code be optimized. Before each request, determine whether X-BM-TIMESTAMP is empty.

3. What is the time used as the timestamp in the API?

UTC 0 timestamp。

4. Why does signature authentication always return invalid signatures?

Caused by incorrect signatures:

You can use the following SDK, the signature part has been packaged, you can directly debug and call:

• bitmart-go-sdk-api
• bitmart-python-sdk-api
• bitmart-java-sdk-api
• bitmart-php-sdk-api

If you are writing your own signature function, please refer to the following description step by step:

The request header of X-BM-SIGN is obtained by encrypting the timestamp + "#" + memo + "#" + queryString, and the secret key using the HMAC SHA256 method.

When checking, you can print out the request header information and the pre-signature string, focusing on the following points:

Whether the APIKey is correctly configured in the code

Your KEY is as follows:

API_KEY = "80618e45710812162b04892c7ee5ead4a3cc3e56";

API_SECRET = "6c6c98544461bbe71db2bca4c6d7fd0021e0ba9efc215f9c6ad41852df9d9df9";

API_MEMO = "test001";

Please confirm that the settings are correct:

Content-Type: application/json

X-BM-KEY: 80618e45710812162b04892c7ee5ead4a3cc3e56

Check whether the string before signing conforms to the standard format, the order of all elements must be consistent, you can use the following example to compare with your string before signing:

Rate Limit Q&A

1.Is there a limit to how often the API is called per second?

There are limits, specific can see the menu bar 'Rate Limit' in each interface access frequency limit.

2."why do I have to complete a CAPTCHA?" comes up on the call

This time, the IP was intercepted because it was accessed too much from a different environment and was considered an attack by the system. It is recommended that you do not share IP and that applications be accessed using a separate IP.Second, use the browser to call the interface and select 'I am Human' to submit to unrestrict as prompted on the page.

3.How is the HTTP status code 429 created?

The request interface exceeds the access frequency limit. It is recommended to reduce the access frequency.

4.Will API call interfaces be blocked if they exceed the access frequency? How long letter?

No, just reduce the access frequency.

5.Access interface error overclocking, how to solve?

Reduce the frequency of access. Each interface of the document has a frequency description. You need to lower the request frequency to the frequency description.
