I am trying to integrate PayPal into my website. And while reading the API tutorials I came across the following snippet.
curl -v https://api.sandbox.paypal.com/v1/oauth2/token \ -H "Accept: application/json" \ -H "Accept-Language: en_US" \ -u "EOJ2S-Z6OoN_le_KS1d75wsZ6y0SFdVsY9183IvxFyZp:EClusMEUk8e9ihI7ZdVLF5cZ6y0SFdVsY9183IvxFyZp" \ -d "grant_type=client_credentials"
Can you please tell what -u stands for in curl? I know that -H stands for http Header and -d Stands for HTTP payload.
Thank you, I tried searching but didn't get any results.
