Unrecognized MultiChain metadata, any way to improve the output? about multichain-explorer

[bitcartel]

What command did you run to create the transaction with metadata?

Please copy the JSON output from multichain-cli mychain getrawtransaction TXHASH 1 and let me know which output contains the metadata and what you see in the explorer.

I'm using the json-rpc interface, so here are the requests, data and responses. The metadata is created in PHP as follows:

bin2hex(hash('sha256', "some content")));

Sending the transaction:

==> Request: 
{
    "jsonrpc": "2.0",
    "method": "sendwithmetadatafrom",
    "id": 1431901949,
    "params": [

Thanks, will look into this.

[bitcartel]

Updated. Explorer now shows the hex metadata.

Works great, thanks
