You dont need to store base64 string in database tables explicitly nor you need any plugins. Just Make sure you are storing the binary document received from first API as appian document and then pass the same using todocument() in the json body for next API call.</p> <p><br />Refer the documentation below for more details and example.&nbsp;</p> <p><a href="https://docs.appian.com/suite/help/25.3/Integration_Object.html#sending-base64-inline-with-json">docs.appian.com/.../Integration_Object.html</a></p><div style="clear:both;"></div>
