Setup a Payment

To set up a payment using mnp, you have several options based on your specific requirements:

1. Simple Transfer (No Payment ID):

This is the recommended way to set up a payment for enhanced privacy.

Create a New Subaddress:

$ mnp payment new
Bdxcxb5WkE84HuNyzoZvTPincGgPkZFXKfeQkpwSHew1cWwNcBXN4bY9YXY9dAHfibRBCrX92JwzmASMXsfrRnQqMo3ubLB

List All Subaddresses:

$ mnp payment list
0 "A13iyF9bN7ReDPWW7FZoqd1Nwvhfh2UbAMBR4UeGPi1aWpERgmE3ChMeJZJ2RnkMueHdL7XXwdkQJ5As8XRhTKAhSwjahXd"
1 "Bdxcxb5WkE84HuNyzoZvTPincGgPkZFXKfeQkpwSHew1cWwNcBXN4bY9YXY9dAHfibRBCrX92JwzmASMXsfrRnQqMo3ubLB"

Select a Specific Subaddress:

$ mnp payment subaddr 1
Bdxcxb5WkE84HuNyzoZvTPincGgPkZFXKfeQkpwSHew1cWwNcBXN4bY9YXY9dAHfibRBCrX92JwzmASMXsfrRnQqMo3ubLB

Returns the subaddress at index 1.

Add an Amount:

$ mnp payment new --amount 65000
# OR 
$ mnp payment subaddr 1 --amount 650000
monero:Bdxcxb5WkE84HuNyzoZvTPincGgPkZFXKfeQkpwSHew1cWwNcBXN4bY9YXY9dAHfibRBCrX92JwzmASMXsfrRnQqMo3ubLB?tx_amount=0.000000650000

Returns a Monero URI string.

2. Including a Payment ID (For Matching Orders):

For scenarios requiring order matching, such as retail transactions or invoicing, use a Payment ID. This is often required for tax regulations and invoice numbering.

Generate a Payment ID:

Generate a unique 16-hex character payment ID using tools like OpenSSL:

# Create a random paymentid (16 hex character)
$ mypaymentId=$(openssl rand -hex 8)
$ echo $mypaymentId
e02c381aa2227436

Returns a random 16-hex character payment ID.

Create an Integrated Address:

Use the generated payment ID to create an integrated address, combining it with your primary address:

# Create an integrated address.
$ echo $mypaymentId | mnp payment
AAkPz3y5yNweDPWW7FZoqd1 ... 5kqxkfnou78gMMeg

Returns an integrated address with the provided payment ID, enabling efficient tracking of payments.

Add an Amount (Optional):

If a specific amount needs to be included in the payment, you can do so using the --amount option:

 $ echo "$mypaymentId" | mnp payment --amount 50000
monero:AAkPz3y5yNweDPWW7FZoqd1Nwvhfh2UbAMBR4UeGPi1aWpERgmE3ChMeJZJ2RnkMueHdL7XXwdkQJ5As8XRhTKAhfT5kqxkfnou78gMMeg?tx_amount=0.000000050000

Returns a Monero URI string.

3. Create a QR-Code (For Customer Convenience):

To facilitate easy payment by customers using mobile Monero wallets, you can generate a QR code from the payment URI.

Install QR Code Generator:

Ensure you have a QR code generator installed on your system. You can install qrencode using:

sudo apt-get install qrencode

Generate QR Code:

Use qrencode to generate a QR code from the Monero URI string:

mnp payment subaddr 1 | tr -d '\n' | qrencode -t UTF8

Monerujo has some problems with \n terminated strings, so it is better to remove them.

These methods provide flexible options for setting up payments using mnp. Every output of mnp payment can be used to create an QR-Code.
