Answers.Body: <p>Based on your code - and our comments - you need something like this:</p>
  
  <pre><code>&lt;form id="someFormId"&gt;

      &lt;input type="hidden" name="handle" value="test"&gt;

  <p>and your javascript like</p>
  
  <pre><code>$("#sendRequest").click(function(){
      var formData = $("#someFormId").serialize();
      //proceed with your ajax request

Answers.Text: Thank you! I refactored my AngularJS form, using jQuery _serialize()_ and the same hidden fields as you suggested: now it works!
  
  I thought that if Sprout Invisible Captcha fields values were not sent, the form would not save. But as you explained, they have to be sent to enable the Sprout Invisible Captcha features.
  
  Regarding how to handle redirect, I simply add something like _window.location.replace($('[name="redirectOnFailure"]').val())_ if _data.success_ is _false_ inside the AJAX submission.

Comments.Text: I have not used the plugin yet but his spam protection does not seem to be too complex. Is creating your own protection no option for you?
  Do you use a custom controller or only craft logic?

Comments.Text: Could you provide more code? 
  You should show us your AJAX request.. otherwise we can't know if you messed up your routing or something like that.
  Do you use a custom controller and link you request directly to it? Because you skip the validation process if you do that

Comments.Text: As I thought... it seems like your `formData` does not even contain all the required fields from sproutForms. The plugin injects your form with several fields -> it adds much content to the form but you only send 2 of them to the plugin -> the plugin does not recognize the protection. 
  you'll need to send all fields in your ajax request. Make a `$('#formId').serialize();` or look for every single field in your form manually.

Title: How can I make Sprout Invisible Captcha plugin works using AJAX submission?
ThreadText: # How can I make Sprout Invisible Captcha plugin works using AJAX submission?
  
  (Asked by: username_0 on 2017-10-06)
  
  I set up a custom form template using Sprout Forms and added `{{ craft.sproutInvisibleCaptcha.protect() }}` inside the `<form>` tag.
  
  I can see there are several captcha tags added by the plugin, but as I am using AJAX submission:
  
  * How can I make it works using this submission method?
  * How do I handle redirect to my 'redirect' location?
  
  I did these tests:
  
  * Prevent a form from being submmitted if a user does not have JavaScript enabled ;
  * Block form submissions by robots who auto-fill all of your form fields ;
  * Require minimum time to fill out your form ;
  
  All of these tests have failed, spam haven't been caught.

  This is the captcha field inside custom Sprout Form template:
  
  ```
  {{ craft.sproutInvisibleCaptcha.protect() }}
  <input type="hidden" name="redirectOnFailure" value="{{ craft.request.getUrl() }}">
  
  ```
  
  And this is the AJAX post inside JS script:
  
  ```
  var postUrl  = 'sproutForms/entries/saveEntry',
      formData = {
      action: postUrl,
      handle: 'test',
      fields: {}
  };
  
  formData['fields[minPrice]'] = $scope.results.minPrice;
  formData['fields[maxPrice]'] = $scope.results.maxPrice;
  
  formData = $.param(formData);
  
  $.ajax({
      type     : 'POST',
      url      : postUrl,
      data     : formData,
      dataType : 'json',
      encode   : true
  });
  
  ```

  Based on your code - and our comments - you need something like this:
  
  ```
  <form id="someFormId">
      <input type="hidden" name="action" value="sproutForms/entries/saveEntry">
      <input type="hidden" name="handle" value="test">
      <input type="hidden" name="redirectOnFailure" value="{{ craft.request.getUrl() }}">
      <!---some more fields-->
      <button type="button" id="sendRequest" value="send">
  </form>
  
  ```
  
  and your javascript like
  
  ```
  $("#sendRequest").click(function(){
      var formData = $("#someFormId").serialize();
      //proceed with your ajax request 
  });
  
  ```
  
  reason: The Plugin checks all your variables in your `$_POST` request. Depending on the keys in this array it checks for spam. In your request you send none of those fields -> the plugin validation does not trigger. You can check which fields are injected with the `{{ craft.sproutInvisibleCaptcha.protect() }}` function and add them manually in your request as well but it's easier to just serialize the form.
