Interacting With a Besu Node in Postman (JSON-RPC API)
	The Besu Private Network Quickstart makes use of cURL, however JSON-RPC requests can also be made in Postman. https://besu.hyperledger.org/en/1.3.0/Tutorials/Quickstarts/Private-Network-Quickstart/#run-json-rpc-requests
	Create a Postman account with your ConsenSys email, and then download and install Postman on your device. https://www.postman.com/downloads/

	Sign into the Postman desktop application. On the menu bar, click on Workspaces and select ‘Create Workspace’. Give the workspace a relevant name and summary, then set the visibility to ‘Personal’.

	Within your workspace, you can import the Besu RPC collection by clicking on Import and selecting ‘Link’. Paste the following address and select Import: https://besu.hyperledger.org/en/stable/postman/postman_collection.json

	Create a new environment by clicking on the eye symbol on the upper right hand side of Postman, then select ‘Add' on the same line as Environment. Use the image below as a guide to create three variables with the current values shown. The http port for Besu is 8545 by default, so if you are running it on a different port, be sure to modify the rpc-http-port and jsonrpc.endpoint values to match that.

	Then click the three dots icon next to ‘Share’ and select ‘Set as active environment’. If you already have a Besu node that is mining running, you can try sending an eth_mining call, of which the result should be true.
