The error 11101 refers to preApproval data is required as stated in your error response. In the Portuguese translation of 'data is requered.' means 'data is required' or 'data is required.' As I understand it, you did not fill out all the fields as required according to the documentation of the Integration Guide of PagSeguro .

PagSeguro Subscription Service URL:

POST https://ws.pagseguro.uol.com.br/v2/pre-approvals/request

The Content-Type header should be reported as in the example below in the documentation:

Content-Type: application/xml; charset=ISO-8859-1

  

Note: If your application or store does not use the   ISO-8859-1 characters, eg (UTF-8), it is necessary to replace the   charset parameter of the above example.

See below structured XML example to represent the data of a payment:

<preApprovalRequest>

 <reviewURL>http://www.seusite.com.br/revisao.php</reviewURL>

 </preApprovalRequest>

Server Response

If the call is successful, PagSeguro will return a XML with the redirect code. The example below shows a successful response to a call to the subscription service:

<preApprovalRequest>
  <code>DC2DAC98FBFBDD1554493F94E85FAE05</code>
  <date>2014-01-21T00:00:00.000-03:00</date>
</preApprovalRequest>

If the request returns in error:

<errors>
  <error>
    <code>11101</code>
    <message>preApproval data is required.</message>
  </error>
</errors>

  

A field that deserves prominence is redirectURL , where it is ONLY   IT WILL WORK IF YOUR ACCOUNT IS ACCOUNTED "I want to receive   only payments via API ";
