AZCaptcha base64 decode images for German Embassy

I am trying to make a program that decodes base64 images, sends the request to an AZCaptcha server, and puts the answer to the label that I want.
When I go to this website I see that the captcha is base64 encoded, and the ID is changeable every time when I press the button Load another picture. In this site there are no unique IDs.
The code should have four functions: one that gets the exact ID (ID is not unique, when you refresh the website, it changes the ID of captcha), another that sends this ID (ID of captcha when I will open the website), to the server, and a third that puts the answer from AZCaptcha server to the next label.
Here are two functions that are used to send and parse the request to the server:
function sendToAPI(base64) {
base64 = encodeURIComponent(base64);
GM_xmlhttpRequest({
method: "POST",
url: "http://azcaptcha.com/in.php",
data: "method=base64&key=" + apikey + "&body=" + base64,
headers: {
"Content-Type": "application/x-www-form-urlencoded"
},
onload: function(response) {
var responseString = response.responseText;
GM_log("Debug(Send): " + responseString);
if (responseString == "ERROR_WRONG_USER_KEY" || responseString == "ERROR_KEY_DOES_NOT_EXIST" || responseString == "ERROR_ZERO_BALANCE" || responseString == "ERROR_ZERO_CAPTCHA_FILESIZE" || responseString == "ERROR_TOO_BIG_CAPTCHA_FILESIZE" || responseString == "ERROR_WRONG_FILE_EXTENSION" || responseString == "ERROR_IMAGE_TYPE_NOT_SUPPORTED") {
userLog("There has been a pretty severe error:" + responseString + ", you should disable the plugin and report this.", "error");
throw new Error("Stopping execution");
} else if (responseString == "ERROR_IP_NOT_ALLOWED" || responseString == "IP_BANNED") {
userLog("For some reason your IP has been banned from the service. You should disable the plugin and report this.", "error");
throw new Error("Stopping execution");
} else if (responseString == "ERROR_NO_SLOT_AVAILABLE") {
userLog("The server is at maximum capacity, we are resubmitting in 15s.", "warning");
} else {
userLog("Captcha sent, awaiting response", "success"); //Should really if this to deal with other responses sooner
setTimeout(parseResponse, 15000, responseString);
}
}
});
}
//Parse the response from the server
function parseResponse(prevResponse) {
var captchaID = prevResponse.split("|");
GM_xmlhttpRequest({
method: "GET",
url: "http://azcaptcha.com/res.php?key=" + apikey + "&action=get&id=" + captchaID[1],
onload: function(response) {
var getResponse = response.responseText;
if (getResponse == "CAPCHA_NOT_READY" || getResponse == "CAPTCHA_NOT_READY") {
userLog("Captcha is not ready yet. Let's wait 10 seconds", "warning");
captchaID = null;
setTimeout(parseResponse, 10000, prevResponse);
//Deal with errors
} else if (getResponse == "ERROR_KEY_DOES_NOT_EXIST" || getResponse == "ERROR_WRONG_ID_FORMAT") {
userLog("Fatal error! We have to quit out of the script. The error was: " + getResponse, "error");
throw new Error("Stopping execution");
} else if (getResponse == "ERROR_WRONG_CAPTCHA_ID") {
userLog("Our ID is wrong, so the server is probably having issues. Wait 15s and attempting resubmit.", "warning");
setTimeout(checkBotcheck, 15000);
} else if (getResponse == "ERROR_CAPTCHA_UNSOLVABLE") {
userLog("Server thought the captcha was unsolvable, so we're going to resend it.", "warning");
setTimeout(checkBotcheck, 5000);
} else {
GM_log("Debug(Response): " + getResponse);
//Assuming we're all good
var captchaArray = getResponse.split("|");
var captchaAnswer = captchaArray[1];
submitToCaptcha(captchaAnswer);
count++;
setTimeout(userLog, 3000, "We think the botcheck is: " + captchaAnswer + ". We are going to wait 15 seconds to see if it was. We have attempted to solve " + count + " botchecks (including retries).", "success");
}
}
});
I want to make an code, that sends to the server, the exact ID of the image, gets the response from the server, and puts the answer to next label.
Can you help me somehow to solve this problem?

Payment Navigation form php to payment gateway and back to php (response back to php page )

i created a login.php file where the user can will be navigated to instamojo payment page . After completing the transaction the user is getting the success message from instamojo , but i need to display the successful transaction in my domain or in own php file . so how can i get the transation related information to my webpage or to my login.php file
Ex: Redirecting from our login.php to instamojo(payment gateway)and response back (success message)to our login.php intimating the user that payment is success
var rootURL = "cgshealthcare.com/HealthCareSystem/";;
$(document).ready(function() {
$('#login').click(function() {
if ($('#username').val() == "" || $('#password').val() == "") {
alert("Please enter username or password");
return false;
}
cardloginUser($('#username').val(), $('#password').val());
});
});
function forwardtoRegister() {
window.location = "login.php?page=register";
}
function cardloginUser(userName, password) {
console.log('userName: ' + userName);
console.log('password: ' + password);
if (userName.length < 1) {
$('#errorlist').html("<font color='red'><b> Please enter User ID</b></font>");
return false;
}
if (password.length < 1) {
$('#errorlist').html(" <font color='red'><b> Please enter Password</b></font>");
return false;
}
console.log(rootURL + '/authenticate/' + userName + '/' + password);
$.ajax({
type: 'GET',
url: rootURL + '/authenticate/' + userName + '/' + password,
dataType: "json",
success: function(data) {
console.log("hello" + data.responseMessageDetails);
var list = data == null ? [] : (data.responseMessageDetails instanceof Array ? data.responseMessageDetails : [data.responseMessageDetails]);
console.log("List : " + list);
if ((list).length < 1) {
$('#errorlist').html("<font color='red'><b> Invalid User Name and Password Combination </b></font>");
$('#errorblock').css("visibility") == "visible";
}
$.each(list, function(index, responseMessageDetails) {
console.log("Status " + responseMessageDetails);
var message = responseMessageDetails.message;
if (message.indexOf("]:") > 0) message = message.substring(0, message.indexOf("]:") + 2);
console.log("message" + message);
console.log("USer Data" + responseMessageDetails.status);
console.log("USer Data" + responseMessageDetails.message);
if (responseMessageDetails.status == "Success") {
window.location = "imjo.in/NpKxN";;
} else if (responseMessageDetails.status == "Fail") {
window.location = "www.google.com";
console.log("Fail1");
$('#errorlist').html("<font color='red'><b>" + message + "</b></font>");
} else {
console.log("Fail111");
$('#errorlist').html("<font color='red'><b> We are sorry some intermittent Issue. Please try after some time. </b></font>");
}
});
},
error: function(data) {
console.log("data...." + data);
var list = data == null ? [] : (data.responseMessageDetails instanceof Array ? data.responseMessageDetails : [data.responseMessageDetails]);
console.log("data...." + data);
$.each(list, function(index, responseMessageDetails) {
console.log(responseMessageDetails);
var message = responseMessageDetails.message;
if (message.indexOf("]:") > 0) message = message.substring(0, message.indexOf("]:") + 2);
$('#errorlist').html("<font color='red'><b>" + message + "</b></font>");
});
}
});
}
function showLogin() {
window.location = "login.php";
}

Please look at the integration guide here.
After user enters payment information on instamojo, they are redirected to a redirect-url which you specify (and is a url on your website). Instamojo appends transaction results to this url. You can make it a php url on your website and read the results using GET method. Depending upon the results, you can process your payment and display results to the end-user. More on GET method here...
Instamojo also provides for webhooks, which are like silent POSTs in the background and can be used as backups in case redirect urls in front-end fail for some reason. This way if end-users' redirection failed for any reason, the webhook will still receive information in the background which can be used you to update your database for success/failure of transaction. Of course you webserver has to be up and running to receive webhooks notifications. If that's the point of failure, nothing will work :)
The API link I shared has all those details.
Thanks

Image upload to Parse Server using Angular and Ionic not working

I have been unable tu upload an image to Parse Server using Angular and Ionic on a hybrid mobile app. I am using the latest version of Parse Sever and the Parse Javascript SDK. I am always getting the error 130: Invalid file upload.
I believe I have to encode the image to base 64, am I correct?
This is my upload code:
$scope.doSignUp = function(){
// if (true)
// {
// $scope.image_error = "* Por favor selecciona una imagen";
//}else{
var file = "";
window.plugins.Base64.encodeFile($scope.collection.selectedImage, function(base64){
file = base64;
});
var imageFile = new Parse.File("image.png", { base64: file },"image/png");
imageFile.save().then(function() {
var user = new Parse.User();
user.set("username", $scope.user.username);
user.set("password", $scope.user.password);
user.set("email", $scope.user.email);
user.set("picture", imageFile);//getting file need url
user.signUp(null, {
success: function(user) {
$state.go('app.home');
},
error: function(user, error) {
// Show the error message somewhere and let the user try again.
alert("Error: " + error.code + " " + error.message);
}
});
}, function(error) {
console.log("Error");
console.dir(error);
alert("Error: " + error.code + " " + error.message);
});
//$state.go('app.feeds-categories');
//}
};

Did you try that?
var user = new Parse.User();
var base64 = "V29ya2luZyBhdCBQYXJzZSBpcyBncmVhdCE=";
var imageFile = new Parse.File("image.png", { base64: base64 });
user.set("username", $scope.user.username);
user.set("password", $scope.user.password);
user.set("email", $scope.user.email);
user.set("picture", imageFile);//getting file need url
user.signUp(null, {
success: function (user) {
$state.go('app.home');
},
error: function (user, error) {
alert("Error: " + error.code + " " + error.message);
}
});

redirect_uri_mismatch error of google API while trying to login using c# asp.net

Upload multiple photos in batch to Facebook using Javascript SDK

I can upload single photos via URL to Facebook, but I'm having trouble doing it using batch. I'm getting the (#324) Requires Upload File uncaught exception. I'm ensuring the user is logged in and when I look at the batch payload (batchJson) it looks okay.
To be clear, if I remove all the batch-related setup code and in the FB.api call replace "batch" : batchJson with a single "url": photoUrl the code works.
Here's my code. TIA for any insight on my error:
var message = $("#message-fb").val();
var batchItems = [];
var photoUrl = "";
$(".photo-selected").each(function () {
photoUrl = $(this).data('content');
item = {};
item['method'] = 'POST';
item['relative_url'] = 'me/photos';
item['url'] = encodeURI(photoUrl);
item['caption'] = message;
batchItems.push(item);
});
batchJson = JSON.stringify(batchItems);
alert(batchJson);
FB.getLoginStatus(function (response) {
if (response.status === 'connected') {
// Already logged in and authorized
FB.api(
"/",
"POST",
{
"batch": batchJson
},
function (response) {
if (response && !response.error) {
/* successful upload */
alert('Photos uploaded to Facebook (nl) - ' + JSON.stringify(response));
}
if (response && response.error) {
/* Provide error info during testing */
alert('Sorry, there was a problem uploading your photo to Facebook - ' + JSON.stringify(response));
}
});
} else {
// Need to login and authorize
FB.login(function () {
FB.api(
"/",
"POST",
{
'batch': batchJson
},
function (response) {
if (response && !response.error) {
/* successful upload */
alert('Photos uploaded to Facebook - ' + JSON.stringify(response));
}
if (response && response.error) {
/* Provide error info during testing */
alert('Sorry, there was a problem uploading your photo to Facebook - ' + JSON.stringify(response));
}
});
}, { scope: 'publish_actions' });
}
});
EDIT: Here are the relevant changes using #CBroe's answer:
$(".photo-selected").each(function () {
var photoUrl = $(this).data('content');
var item = {};
item['method'] = 'POST';
item['relative_url'] = 'me/photos';
var itemUrl = encodeURI(photoUrl);
var itemCaption = encodeURIComponent(message);
item['body'] = "caption=" + itemCaption + "&url=" + itemUrl;
batchItems.push(item);
});
batchJson = JSON.stringify(batchItems);

You are sending url and caption parameters on the same “level” as the method and relative_url – they need to be put inside a body property however. And the content of that field has to be encoded the same way an actual POST request via a form would be encoded (so like a URL query string, param1=value1&param2=value2).
