(415): Unsupported Media Type - Json

[EduardoRocha96]

Hey guys, Can you help me? I'm trying to generate the accesstoken for integration via API, but I keep getting the same error message.

() =>
let
body = Json.FromValue([
grantType = "client_credentials",
clientId = "clientId",
clientSecret = "clientSecret"
]),
response = Json.Document(
Web.Contents(
url,
[
Headers = [
#"Content-Type" = "application/json"
],
Content = body
]
)
)
in
response[accessToken]

@EduardoRocha96  - Json.FromValue is incorrect.  You need to define a text string and convert it to a binary file type.

let
    url = "https://merchant-api.ifood.com.br/authentication/v1.0/oauth/token",
    #"Client Id" = "c9daf25e-6b3d-4e7b-9eed-36792df10be9",
    #"Client Secret" = "l4jkpmdp4axfyn60olr8685s85f8yvq3hugf5h1jztq65tjx8mbg209ljcj4bjxd5vg13s1k21gm869oyaa5y509az47ll8buy3",
    body = "grantType=client_credentials&clientId=" & #"Client Id" & "&clientSecret=" & #"Client Secret",
    #"body to binary" = Text.ToBinary( body ),
    response = Web.Contents(
            url,
            [ 
                Headers = [ #"Content-Type" = "application/x-www-form-urlencoded" ],
                Content = #"body to binary"
            ]
        ),
    open = Json.Document( response ),
    token = open[accessToken]
in
    token

Hi @EduardoRocha96 

If think you need to change the Content Type from "application/json" to "application/x-www-form-urlencoded".  Please refer to the following documentation for more information.  iFood Developer | Referências .  Sorry I can help anymore because it is difficult to test without access.

I tried changing the content-type, but now another error is appearing:

(400) - Bad request

I have trial access if you need it 🙂

clientId = "c9daf25e-6b3d-4e7b-9eed-36792df10be9",
