HI,

I read the document : https://airtable.com/appEYx9XUfEttr3Nr/api/docs#curl/table:table%201:update
I just copy and past the code… and i get errors… but getting records or creating records it is working…

I put the api_key as a parameter and in headers both doesn’t work for updating the records…
In the header is put Content-Type: application/json
