To access Parallel through its API, you will need access tokens before making any calls.
To manage these tokens, go to Settings from your profile menu located on the application's bottom left side.
Then, select the API Tokens option to open the list with the active tokens that you have.
If you need to create a token, select the option Create token and introduce a name to identify that token.
After introducing the identifier and clicking on the Create option button, the created token will appear on the screen.
For security reasons, the token will only be visible at this moment. Make sure to copy it to use it.
If you lose the token by any chance, you can always delete it and create another. Remember, never store the token in unsafe places to avoid any misuse.
