Thanks, but is there no RPC API in LND? Maybe I made some wrong assumptions about how this works. What is LND's port 10009 supposed to do? I though that was for RPC calls, or does that serve another purpose?

That is not jsonrpc but grpc. If you want to use that you have to compile the interface proto file to the language of your choice and include the interface stub in your client code.

So.. it's not possible to do this with just one curl command? (as is the case with bitcoind)

You can query rest api wth curl. There are curl examples in the rest api link above.

Very much appreciate your comments btw, thanks a lot. I'm now looking through the [REST API documentation](https://api.lightning.community/rest/index.html?shell), however the first example shows the creation of the macaroon header, and a curl command line which uses the tls.cert file in the LND directory. But isn't this supposed to work from somewhere remote, i.e. without having access to local files on the server (i.e. the tls.cert and the .macaroon file)? Or are they supposed to be copied to a remote client location from where you want to call the LND server's REST API?

Exactly, they need to be copied to the client. Check out the full LND getting started guide, it describes this in very well.

Just making sure I'm not doing something wrong, I now got this working fine:
`curl -X GET --cacert $LND_DIR/tls.cert --header "$MACAROON_HEADER" https://localhost:8080/v1/genseed` However the response is `{"error":"wallet already exists","code":2}` rather than the seeds. So the connection and macaroon authentication is working fine. But *any* other command I try instead of `genseed`, such as `getinfo` or `peers` or `payments` (all as GET requests, no params) returns `Not Found` in all cases. Am I still missing something?

@Rog I have the same problem, except I get `Not Found` for `genseed` as well. Were you able to find a solution?

<p>LND has two API interfaces:</p>
<ol>
<li>On port 8080 is a REST RPC interface</li>
<li>On port 10009 is a GRPC interface.</li>
</ol>
<p>The REST interface on 8080 needs a macaroon file and an optional tls certificate.<br />
You can use CURL like this:</p>
<pre><code>MACAROON_HEADER=&quot;Grpc-Metadata-macaroon: $(xxd -ps -u -c 1000 ~/.lnd/admin.macaroon)&quot; 
curl -X GET --cacert ~/.lnd/tls.cert --header &quot;$MACAROON_HEADER&quot; https://192.168.0.7:8080/v1/getinfo
</code></pre>
<p>if you want to ignore tlc.cert add <code>-k</code> option to the curl call.</p>
<p>The parameters above are:</p>
<ol>
<li><code>~./lnd/admin.macaroon</code>: is the path to your nodes macaroon file (generated by your lnd node)</li>
<li><code>~/.lnd/tls.cert</code>: is the path to the tls cert file (generated by your lnd node)</li>
<li><code>192.168.0.7:8080</code> is the IP and port of the RPC of your LND node, if its on the same machine you can just use <code>localhost:8080</code></li>
</ol>
<p>You need the following settings in your lnd.conf:</p>
<ul>
<li><code>restlisten=0.0.0.0:8080</code> this tells LND to listen to RPC requests on port 8080</li>
<li><code>no-rest-tls=true</code> - this allows you to disable tls certificates</li>
</ul>

LND has two API interfaces:

On port 8080 is a REST RPC interface
On port 10009 is a GRPC interface.

The REST interface on 8080 needs a macaroon file and an optional tls certificate.
You can use CURL like this:
MACAROON_HEADER="Grpc-Metadata-macaroon: $(xxd -ps -u -c 1000 ~/.lnd/admin.macaroon)" 
curl -X GET --cacert ~/.lnd/tls.cert --header "$MACAROON_HEADER" https://192.168.0.7:8080/v1/getinfo

if you want to ignore tlc.cert add -k option to the curl call.
The parameters above are:

~./lnd/admin.macaroon: is the path to your nodes macaroon file (generated by your lnd node)
~/.lnd/tls.cert: is the path to the tls cert file (generated by your lnd node)
192.168.0.7:8080 is the IP and port of the RPC of your LND node, if its on the same machine you can just use localhost:8080

You need the following settings in your lnd.conf:

restlisten=0.0.0.0:8080 this tells LND to listen to RPC requests on port 8080
no-rest-tls=true - this allows you to disable tls certificates
