How to call request in Postman - post

Question

I have request to rest api. Request from help page looks like:
curl -X POST \
'https://allegro.pl/auth/oauth/device' \
-H 'Authorization: Basic base64(client_id:client_secret)' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'client_id={client_id}'
How to call above request from Postman? I've choosed POST type. In url I've pasted https://allegro.pl/auth/oauth/device.
But now I have problem. Which tab I should choose? On Authorization tab in Postman I have autorization type. And there is Basic Auth but I have to type username and password and I don't have both of them because I have only client id and secret id. On the Headers tab I can add two parameters: Authorization and Content-Type. But it doesn't work. I don't know if I should additionally put clientid:secretid into base64 and then past to the Value input?
Where I should past parameter -d clientid ?

Answer 1

Simply, you can just import your cUrl to Postman as follow:
Click on "import" tab on the upper left side.
Select the Raw Text option and paste your cURL command.
Hit import and you will have the command in your Postman builder!
Answering your questions:
Which tab I should choose? On Authorization tab in Postman I have
authorization type
You have two options:
You chose Authorization tab, chose type as Basic Auth, and yes put client_id as Username and client_secret as Password, cause it concatenate them with a colon (:) in-between and base64-encode this string, check Basic Auth RFC for more details, and this will automatically set Authorization key in your headers.
Or chose Headers tab, and paste directly the string if you have it ready encoded as Basic base64({{client_id}}:{{client_secret}}).
Where I should past parameter -d clientid ?
That's your request body in application/x-www-form-urlencoded as keys and values, so you set key as client_id and value as {{client_id}}.
