title: Facebook Marketing API : Sharing Custom Audiences
body: <p>I'm trying to create, add users, remove users to custom audiences and then share those audiences with other accounts. I have gotten all of these working except for the sharing part. </p>
  
  <p>The api docs seem very vague on how to actually do this. Here is what it says:</p>
  
  <blockquote>
    <p>Share your custom audience with business objects at
    '/custom-audience/share_with_objects'</p>
  </blockquote>
  
  <p>Does anyone know how to do this through the API? I imagine you'd need the AD_ACCOUNT_ID and the CUSTOM_AUDIENCE_ID in some capacity.</p>
  
  <p>for reference that quoted line above is from here <a href="https://developers.facebook.com/docs/marketing-api/audiences-api" rel="nofollow noreferrer">https://developers.facebook.com/docs/marketing-api/audiences-api</a>
  under the header Building a Custom Audience</p>
  
  <p>Thanks for the help. </p>
