Hi Dhanish,
Whilst this isnt an immediate help to you, over the next couple of months we will be making more integrations available for Adobe Sign. You may want to consider this as a possible solution for the near future. The Adobe Sign API is quite large and as such has been broken down into functionality groups, hence the reason for the time required to have it all done.
I hope this helps.
regards
