Google Script API + Oauth + Tumblr

Hello,

I'm trying to acess, perform a post, into Tumblr with Oauth api provided by Tumblr) http://tumblr.com/api). I'm using Google Script and I've tryied too many solutions but anyone worked. To implement i've basaed myself into this(https://developers.google.com/apps-script/articles/twitter_tutorial) Google script twitter tutorial, once on Tumblr API web page they say that twitter api is almost the same that tumblr.

Contextualizing,

I've already set the Oauth class methods with data below and substituted consumer and secret keys with values got from the api i've created.

var oauthConfig = UrlFetchApp.addOAuthService("tumblr");
  oauthConfig.setAccessTokenUrl(
      "http://www.tumblr.com/oauth/access_token");
  oauthConfig.setRequestTokenUrl(
      "http://www.tumblr.com/oauth/request_token");
  oauthConfig.setAuthorizationUrl(
      "http://www.tumblr.com/oauth/authorize");
  oauthConfig.setConsumerKey(<i>consumerkey</i>);
  oauthConfig.setConsumerSecret(<i>consumerSecret</i>);

Error,

The code below isnt working as it should be.

var requestData = {

      "method": "POST",
      "oAuthServiceName": "tumbler",
      "oAuthUseToken": "always"
    };
     var result = UrlFetchApp.fetch(
       "https://api.tumblr.com/v2/blog/{blog}.tumblr.com/post?type=text&body=word",
          requestData);

The Script to Twitter is almost the same and it works. Im able to perform tweets.

var result = UrlFetchApp.fetch(
          "https://api.twitter.com/1/statuses/update.json?status=" + tweet,
          requestData);

Response From Server

Request failed for returned code 400. Server response: {"meta":{"status":400,"msg":"Bad Request"},"response":{"errors":["Post cannot be empty."]}}

Possible Solutions

A possible solution can work using this information(got from tumblr.com/api): OAuth The API supports the OAuth 1.0a Protocol, accepting parameters via the Authorization header, with the HMAC-SHA1 signature method only. There's probably already an OAuth client library for your platform.

My question is, what am I doing wrong?(my post inst empty, i have 2 params). Had anyone had the same problem? Someone has suggestions?

Thank You.

Solution

I don't know anything about the tumblr api, but your http post is empty (the oAuth parameters aren't in the post body, they're advanced options), the body of the post needs to go in the "payload" parameter. See the section "Advanced parameters" in the docs. Or, as you aren't using the post can't you use a get request instead? Remove the method: POST parameter (GET is the default).
