Per @zerotobtc and #537, the arguments were wrong. Replaced with `getnewaddress` to maintain the example about argument order.

After you know where your funds are, the next step in crafting a transaction is to get a change address. By now you've probably got the hang of this, and you know that for simple RPC commands, all you need to do is adjust the `method` is the `curl` command:
```
$ curl --user StandUp:8eaf562eaf45c33c3328bc66008f2dd1 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getrawchangeaddress", "params": ["", "legacy"] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/ | jq -r '.'

At this point, we can even revert to our standard practice of saving results to variables with additional help from `jq`:
```
$ changeaddress=$(curl --user StandUp:8eaf562eaf45c33c3328bc66008f2dd1 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getrawchangeaddress", "params": ["", "legacy"] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/ | jq -r '.result')
$ echo $changeaddress
$ newaddress=$(curl --user StandUp:8eaf562eaf45c33c3328bc66008f2dd1 --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getnewaddress", "params": ["", "legacy"] }' -H 'content-type: text/plain;' http://127.0.0.1:18332/ | jq -r '.result')
$ echo $newaddress

No need to worry about the downloading info. It'll go to `STDERR` and be displayed on your screen, while the results go to `STDOUT` and are saved in your variable.
## Create a Transaction
You're now ready to create a transaction with `curl`.
