Can you please help me understand this? " that you previously got"

[jack-fdrv]

open myapp.php and type the clientId, clientSecret and redirectUri that you previously got from the API Center. Please, read carefully the comments in the example.

What mean " that you previously got", got how? I should first get something to use this library?

Also, seems it require, accessToken, refreshToken, expiresIn.
How I can get it?

In addition to this, a full example is available in the example directory. This includes example.php that gets an access token and requests the data.

So this script should already get the tokens, but how?

@jack-fdrv , please, follow the official Upwork API documentation at https://developers.upwork.com/?lang=php#getting-started

Also, note that OAuth2 authentication is NOT shared for public usage. So, if you don't participate as a beta tester, you need to use the library for OAuth1, which can be found here https://github.com/upwork/php-upwork
