This is the final step in the LC process, where we send a closing transaction to update the letter's status to CLOSED.

Click Close—POST method, and provide the following data:

{
  "$class": "org.example.lc.Close",
  "lc": "resource:org.example.lc.LetterOfCredit#LC-CA-501P10",
  "closeReason": "LC completed"
}

If you were able to follow the instructions and successfully get to this step, congratulations! You are now able to build an application and generate a business domain REST API based on the deployed business network model!
