converttopsbt "hexstring" ( permitsigdata iswitness )

Converts a network serialized transaction to a PSBT. This should be used only with createrawtransaction and fundrawtransaction
createpsbt and walletcreatefundedpsbt should be used for new applications.

Arguments:
1. hexstring        (string, required) The hex string of a raw transaction
2. permitsigdata    (boolean, optional, default=false) If true, any signatures in the input will be discarded and conversion
                    will continue. If false, RPC will fail if any signatures are present.
3. iswitness        (boolean, optional, default=depends on heuristic tests) Whether the transaction hex is a serialized witness transaction.
                    If iswitness is not present, heuristic tests will be used in decoding.
                    If true, only witness deserialization will be tried.
                    If false, only non-witness deserialization will be tried.
                    This boolean should reflect whether the transaction has inputs
                    (e.g. fully valid, or on-chain transactions), if known by the caller.

Result:
"str"    (string) The resulting raw transaction (base64-encoded string)

Examples:

Create a transaction
> bitcoin-cli createrawtransaction "[{\"txid\":\"myid\",\"vout\":0}]" "[{\"data\":\"00010203\"}]"

Convert the transaction to a PSBT
> bitcoin-cli converttopsbt "rawtransaction"
