HTML into API REST

Hi,

I am trying to create request within SDP using REST API but I am having difficulties.

When I enter the description textually I have no problems. However, when I enter the description in HTML code it shows an error message indicating that the account cannot be found.

Query:

data={
"operation": {
"details": {
"description": "<style type=\"text/css\">table{border-collapse: collapse;border:0;width:100%,background-color:#e0e0e0}center{ width:100%}.td_header_1{padding: 20px 0px;background-color: #1e1e34;width: 20%;text-align: center}.td_header_2{ padding: 20px 0px;font-size: 15px; color: #ffffff;background-color: #1e1e34;width: 80%;height: 20px;text-align: center}.logo{ margin: auto;width: 159px;height: 50px; padding-left: 15px}</style><table><tbody> <tr> <td> <center> <table> <tbody> <tr> <td class=\"td_header_1\"> <img class=\"logo\" src=\"\"> </td> <td class=\"td_header_2\"> Text </td> </tr> </tbody> </table> </center> </td> </tr> </tbody> </table>",
