MEXC API Postman

Postman is an API Collaboration Platform.

MEXC now offers several Postman Collections and Environments (JSON files) for a quicker and easier usage of our RESTful APIs.<br/> You only need to import and set up with your own API and secret keys to begin.

How to import and configure

• Download the mexc-api-postman repository.

• Click the Import button. On Postman for Mac, for example, the button is at the top left:

• On the Import pop-up page, select the Folder tab. Click the Choose folder from your computer button and choose the root folder of the downloaded repository.

• Select which collections and environments you would like to import and click the Import button.

• Select the Environments tab on the left, choose an environment, and set your Api Key and Secret Key by changing the Current Value column (see screenshot); (The Timestamp, Signature, Initial Value fields can be left empty as they’ll be automatically filled by Postman when sending a request.)

• Select your newly-added environment from the environment dropdown menu. On Mac, this is at top right, to the left of the eye icon.

Postman safety practices

The following practices are advised to secure your account's safety:

• Don't use Collections obtained from an unknown source.
• Review the environment JSON file before its usage.
• Don't use any code that you don't understand.
• Make sure that the withdrawal permission is not enabled for your API keys.
• When you finish trying out the API, delete your API keys.

FAQ

Q: Why I can't get any response?

You haven't imported the environment file or you've imported it but haven't selected it from the dropdown menu (mentioned in [[How to import and configure]])

Q: How can I debug a request or find the used URL?

• Open the Postman's console to find requests' parameters and URL.
