// This will put the form in testing mode and allow you to test without an SSL certificate

Payment Methods (methods) [Optional]

This Promise based callback is used to handle the event when a user starts a payment method and before any information is sent to Moyasar's API. You can use this to perform any last second validations or to prepare something.

When you handle this event, you can return a false to stop the payment process, or a dictionary that is either empty or contains description or callback_url values to update the form configurations if you need to.

Here is an example to stop the form from submitting:

on_initiating: async () => {
  return false;
};

Make the form proceed:

on_initiating: async function () {
    return {};
}

On Completed (on_completed) [Optional]

This event is fired when a payment is created by Moyasar's API. You can, intercept the payment to save it or do any other processing, by providing a Promise based callback;

Example:

on_completed: async function (payment) {
    // savePayment is just an example, your usage may vary.
    savePayment(payment)
}

On Failure (on_failure) [Optional]

This event is used to handle payment failure, you will get a string if there is an error.

Example:

on_failure: async (error) =>
  new Promise((resolve, reject) => {
    // Handle error
    resolve();
  });

On Redirect (on_redirect) [Optional]

When the form finishes it work and is about to redirect the user, you can intercept this action and handle redirection manually. Here is an example:

on_redirect: async (url) =>
  new Promise((resolve, reject) => {
    // Handle redirection manually
    resolve();
  });
