Introduction
The MicroPayments plugin allows you to create a digital wallet for your users, reward them with points, and let them pay for them using real money.

Wallets: What is a Wallet?
The Wallets are the "accounts" to which the points have to be connected to. They work very similar to bank accounts, or real life wallets.

Transferring Points Between Users
To transfer points between user wallets directly (give someone points) you have to create a page with the shortcode:
Shortcode: [transfer_wallet_points]
Description: Shows the form which allows making a transfer of points from your own wallet to the other wallet with the known ID or username. Of course, only the amount of points lower or equal to the amount of points available on the wallet, and not less than "1" can be sent.
When you place the shortcode on the page, the form for transferring points on the front-end can look like a bit differently in some cases. Let's consider them all step-by-step.
One or Multiple Wallets
The appearance of the form can depend on if the option Assign a single wallet to each customer in plugin options is enabled. To find this option navigate to Admin Dashboard → CM Micropayment Platform → Settings → General tab.
When the option Assign a single wallet to each customer is enabled, each user can have only one wallet assigned to him. 
So, in the form for transferring points the user just needs to choose in the To User (1) dropdown menu to which user he wants send the points to. Then define the amount of points to send in the points to transfer (2) field and click the button Transfer points (3).
If the option Assign a single wallet to each customer is disabled, each user can have more than one wallet. In this case there will be the field To Wallet ID instead of To User. 
The user has to know the wallet ID of the user, which he wants to send points to. 
Admin View
The admin has more possibilities than regular users. In the form for transferring points a new field appears for that role - From Wallet ID. 
It means, he can send points not only from his wallet, but also from the wallet of any other user. By default, in the field From Wallet ID is written admin first wallet ID - to send points from another user wallet he needs to paste another wallet ID.
Adding Comments
You can let users add comments when they perform a transfer. To do so, add these parameters to the shortcode:
- comment_enable - Set "0" to disable comments and "1" to enable them.
- comment_required - Set "0" for optional, "1" for required. Only works if comment_enable parameter is enabled.
Example: enable adding comments that are not required.
[transfer_wallet_points comment_enable="1" comment_required="0"]
A text area Comment will appear in the form:
These comments can be seen only in the back-end for the admin in wallets transactions of two users - sender and receiver.
Successful and Error Messages
There are a few types of messages for sending points.
If everything is correct, the points will be transferred immediately, and the user will see the message that the points are sent successfully. 
Otherwise a message with the error will be displayed, for example that the wallet does not have enough points.
Or if the user entered the value less than 1. 
Labels
All labels and messages in the form can be customized or translated to another language. To do this, navigate to Admin Dashboard → CM Micropayment Platform → Settings → Labels tab.
Here are the labels that you can change in the form for transferring points:
Variable Value
A few labels contain the "%s" symbol.
In the "Transfer successful. Transferred %s points from %s to %s" label, first "%s" will be substituted with the sent amount of points, and the second and third "%s" will be substituted by wallets IDs of sender and receiver respectively.
In "%s to transfer:" and "Transfer %s" labels, "%s" will be substituted by the name of points on your site. You can change the name of points to the one you need in first two labels - for plural and for singular name of points.
End Result
Following instructions found in the plugin and guides, you should be able to configure the form to let users send points to each other.
