Hi nicolast29,

In fact, 'Content' is an optional parameter in web connector and it should list at the same level as 'Header':

let
    vToken = "Bearer " & "TokenXXX",
    vSecret = "SecretXXX",
    vsociety = "XXXX",
    rootURL = "https://api.myunisoft.fr/api",
    body = "{}",
    relativePath = "/v1/export/FEC",
    //vUrl = "https://api.myunisoft.fr?export_type=1&from=2021-01-01&to=2021-12-30",
    Source =
        Json.Document(
            Web.Contents(
                rootURL,
                [
                    Headers = [
                        Authorization = vToken,
                        #"X-Third-Party-Secret" = vSecret,
                        #"society-id" = vsociety,
                        #"Content-Type" = "application/json"
                    ],
                    RelativePath = relativePath,
                    Content = Text.ToBinary(body),
                    Query = [
                        export_type = "1",
                        from = "2021-01-01",
                        to = "2021-12-30"
                    ]
                ]
            )
        )
in
    Source

I'm not so sure which type of content your API requirement, maybe you can check the API document and add the corresponding JSON strings in the 'body' step.
