how to get the document url to add custom fields using docusign api

Question

I am trying to integrate docusign embedded signing into my hybrid app and i am loading the signing url in an iframe in my app, but is there any way to add some more custom fields on the fly using that signing url and make it in an unlocked state so that i can drag them where i want, and then make those fields locked at the time of sending to the sender for signing, also how to get the url of that document after he has signed it so that i can view it later.

Since i am a newbie in this please help me.

This is my code to get the signing url

<?php
$min=100;
$max=300;
$random = rand($min,$max);
$recipientId=rand();
require_once('vendor/autoload.php');
//require_once('./docusign-php-client/autoload.php');
// DocuSign account credentials & Integrator Key
$username = "testmail@mail.com";
$password = "test1234";
$integrator_key = "[integrator-key]";
$host = "https://demo.docusign.net/restapi";
// create a new DocuSign configuration and assign host and header(s)
$config = new DocuSign\eSign\Configuration();
$config->setHost($host);
$config->addDefaultHeader("X-DocuSign-Authentication", "{\"Username\":\"" . $username . "\",\"Password\":\"" . $password . "\",\"IntegratorKey\":\"" . $integrator_key . "\"}");

Answer 1

If you want to place additional fields on the document as a sender, you should use the Embedded Sending (or Sender View)

The Embedded Sending view of an envelope allows users to edit the tabs, documents, recipients, and other settings of draft envelopes before sending them out for approval. Similar to Embedded Signing, your app or website can generate a sending URL and integrate directly into your workflow using a Redirect, Webview, or an iFrame.

See here for the code sample.
