title: How to create sub accounts for my clients in my DocuSign account, and subscribe on behalf of my client via API?
body: <p>I have a system in which I am integrating the DocuSign API.</p>
  
  <p>Inside my system my client can send a document to the emails that it defined. </p>
  
  <p>I have a DocuSign account with the Integration Key enabled on my system, how do I register within my account the subaccounts for each of my clients to send their contracts to their clients using the API?</p>
  
  <p>I have already tested the entire Docusign API, I just can not find how to register sub-accounts to send on behalf of each client of mine!</p>
