You can found all information in your dashboard.

Each payment method class inherits from a base class. To initiate a payment, select the class corresponding to the desired payment type. Start by invoking the initialize_order method with essential attributes, including a float amount, a string payment_reference, and a hash for billing_data containing required keys: first_name, last_name, email, and phone_number. Subsequently, use the payment_link method to obtain the payment link.

The available class for each payment type are:

• Paymob::PaymentTypes::Onetime
• Paymob::PaymentTypes::Wallet
• Paymob::PaymentTypes::Installment

Use the Paymob::PaymentTypes::Onetime class:

payment_data = {
  amount: "Your value in numbers",
  billing_data: {
    first_name: "Test",
    last_name: "Account",
    email: "test@email.com",
    phone_number:"01111111111"
  },
  payment_reference: "Your generated payment reference"
}
onetime = Paymob::PaymentTypes::Onetime.new
onetime.initialize_order(payment_data)
onetime.payment_link

Use the Paymob::PaymentTypes::Wallet class:

Note: you must pass the mobile number wallet you need to pay from it

payment_data = {
  amount: "Your value in numbers",
  billing_data: {
    first_name: "Test",
    last_name: "Account",
    email: "test@email.com",
    phone_number:"01111111111"
  },
  payment_reference: "Your generated payment reference"
}
wallet = Paymob::PaymentTypes::Wallet.new
wallet.initialize_order(payment_data)
wallet.payment_link(mobile_number: '01010101010')

Use the Paymob::PaymentTypes::Installment class:

payment_data = {
  amount: "10",
  billing_data: {
    first_name: "Test",
    last_name: "Account",
    email: "test@email.com",
    phone_number:"01111111111"
  },
  payment_reference: "Your generated payment reference"
}
installment = Paymob::PaymentTypes::Installment.new
installment.initialize_order(payment_data)
installment.payment_link

The Paymob::Hmac class provides helpful methods for handling HMAC operations. Below are the explanations of each method:

calculate

This method accepts a hash of parameters and returns the HMAC for these parameters.

Example:

hmac = Paymob::Hmac.calculate(params_hash) # 6d9bb40e5b46b7166bb032cb075c8921

matches_original?

This method compares the HMAC generated from the provided parameters with an original HMAC and returns a boolean value indicating whether they match.

match = Paymob::Hmac.matches_original?(response_params, original_hmac) # true
