Errors

i have customized the errors from this package starting with BIGBOBLITTLE followed by the error itself

Note

The epaygh momo API

1. requires you to re-generate your Authorization Token after every 3600(1hr). This package takes care of that, by first creating the Authorization Token for you and saves its expiration time in a file called yourtoken. it then checks if the Token is expired and re-generate a new one before sending your momo request to the epaygh API. You can check the generated token and expiration time in a file called yourtoken`

 **the actual api required parameters of epaygh**
{
    amount: 1.0,
    customer_email: "[email protected]",
    customer_name: "Customer Name",
    customer_telephone: "057XXXXXXX",
    mobile_wallet_network: "tigo",
    mobile_wallet_number: "057XXXXXXX",
    payment_method: "momo",
    reference: "000000"
  }

2. the API requires you to provide the above information as parameters to the momo API
   Not all the information here matches my use case when creating the package. so i've set the
   customer_telephone: "057XXXXXXX",` and `mobile_wallet_number: "057XXXXXXX",
   to the phonenumber of the user you're charging.

3. Also, i've used shortid to auto generate the reference for you.

4. I've also taken care of the mobile_wallet_network: "tigo" For this reason, you have to always make sure the phonenumber you pass to this package is always a 10 digit string. Without it, you will get an error.

5. I realized my use case dont really need my customers email :::: customer_email: "[email protected]", however, i've provided that field, but without it, you can still charge your customers.

6. Finally, you'll need your reference to get your transaction status. Its always part of the success response from the api
