In order to generate an API Key you should log in to your account, go to the 'Settings' - 'API integration' section and click on the 'Generate API key' button.
In case your 2FA is turned off you will be asked to switch on this function to ensure safe and secure Keys usage.
Next you will be presented with the 'Generate new key' window where you will be able to name your API Key and set an expiration date (if needed). By default the validity of the API key is 1 year.
After that you should enter your 2FA code and wait for an API Key to be generated. Once an API Key is generated you will see an API Key itself. Please, make sure to save this data as it is shown only once.
Congratulations. You should have successfully managed to integrate our API functionality. In case you have any questions - feel free to contact us (email@example.com). We will be glad to help you.
