Issue with POST request with API oauth2 / return: error 415-CodePudding

i have some issues with an API with oauth2 authentification. After i get the token, and i want to sent my POST request but it still give me a 415 error (Unsupported Media Type) i'm sure my payload's field are good because i tryed with postman and it works, but doesn't know if i have to JSON stringify the header (the payload i thinks but i'm not sure at 100%). I run my code on Google apps script so i thought the problem came frome apps script but i can get the token and send GET request on it. I put you my code below, if anyone can help this would be very helpfull, i wich you a good day, thanks in advance for you'r help. Joseph

CodePudding user response：

415 is unsupported media. This is usually due to Content-Type header typos. Your script is stringifying headers, which would make header unreadable by the server. Try

var options = {
    "method": "POST",
    "header": /*header*/header1,
    "payload": payload
}
