Does anyone know how to create the RequestInit? An example will be wonderful

I've used the following

init = js("{" +
        "\"method\": \"GET\"," +
        "\"headers\": {" +
        "\"Accept\": \"application/json\""+
        "}" +
        "}"))

But I don't know if it is the best way to define this object

You need jso factory function instead

[turansky]

val init: RequestInit = jso {
    method = ...
}

Thanks a lot. I have solved the doubt I had

Here a little snipped from what I use:

fun newTokenRequest(
    code: String,
    redirectUri: String,
): Promise<Response>{
    val fetchURL = "${environment.KEYCLOAK_URL}/realms/${environment.KEYCLOAK_REALM}/protocol/openid-connect/token"
    val body = "grant_type=authorization_code&client_id=${environment.KEYCLOAK_CLIENT}&code=$code&redirect_uri=$redirectUri"

    val request = RequestInit(
        method = "POST",
        // The POST needs the same redirect_uri as the GET that was used to fetch the code.
        body = body,
        headers = json(
            *listOf(
                Pair("Content-Type", "application/x-www-form-urlencoded")
            ).toTypedArray()
        ),
        mode = RequestMode.CORS
    )
    return window.fetch(fetchURL, request)
}

For headers - Headers can be used
