Is it possible to forward signed transaction using bitcoind prune mode? Summary:
Is it possible to perform createrawtranscation , signrawtransaction and sendrawtransaction rpc call using bitcoin in prune mode?
Detail :
I want to implement an API that performs p2p BTC transfer, and for this purpose, I don't want to run a full node in my AWS server as I have to buy extra space for this. I was exploring third-party applications but all of them are out of my budget. So I was curious if I could run prune mode BTC core to perform above mention RPC call?
I would be very thankful if you guys can give some advice as per my requirement.

Yes
I did the transactions in below link using pruned node:

rescanblockchain might be required if you are using any imported addresses in the transactions and it will work only for blocks saved on disk
I had to use rescanblockchain in this example: https://bitcoin.stackexchange.com/a/99112/103136
