Before Stripe implements, You must have a Stripe account and when you log in with that account then stripe will provide you, API Keys, as below.

1. Test API Keys
2. Live API Keys

Step 4: Now Create the Product from Stripe navigation as mentioned below images

Step 5: Now go to a particular product that was created in Stripe and create a plan for that product as many as you needed with different prices and names.

 

Step 6: Now you can see ID of plan in the above image and we need to copy that and use it in the subscription plan.

Step 7: Include <script src="https://js.stripe.com/v3/"></script> in your page from https://stripe.com/docs/stripe-js. and setup code

Step 8: Download the Stripe page with a composer or direct folder from this current repository Repository (application/third_party/stripe/).

Step 9: include the Stripe PHP library in the controller.  and set secret key. and include bellow link

 require_once APPPATH."third_party/stripe/init.php";

now write the code for subscribing plans as given bellow code.

if(!empty($_POST['stripeToken']))
{
    //include Stripe PHP library
    require_once APPPATH."third_party/stripe/init.php";
    StripeStripe::setApiKey(SECRET_KEY);

     $customer = StripeCustomer::create(array(
	'email' => trim($this->input->post('email')),
	'source' => $this->input->post('stripeToken')
     ));

    // Get selected plan id 
    $selected_plan = null;
    $plans = StripePlan::all();
    foreach ($plans->data as $p) {
       if($p['nickname'] == strtolower(trim($this->input->post('plan')))) {
	  $selected_plan = $p;
	  break;
       }
     }

     $subscription = StripeSubscription::create(array(
	'customer' => $customer->id,
	"items" => array(
	     array("plan" => $selected_plan['id'],),
	),
	'trial_period_days' => 14,
      ));
	
      if (isset($subscription)) {
	  $dataArr['payment_status'] = 1;
	  $dataArr['subscription_status'] = 1;
	  $dataArr['stripe_customer_id'] = $customer->id;
	  $dataArr['subscription_id'] = $subscription->id;
      }

      $inserted_id = $this->users_model->common_insert_update('insert', TBL_USERS, $dataArr);
      $result = $this->users_model->get_user_detail(['id' => $inserted_id]);
      $this->session->set_userdata('stripeInCI', $result);
      $this->session->set_flashdata('success', 'User has been created successfully!');
      redirect('home');
}

Step 10: Go to stripe account and check the customer & subscription menu from the navigation bar

Note: This is stripe API documentation https://stripe.com/docs/api where you can check the code and parameter for particular API

If you want to implement any technology then you must need to follow the above steps

2. Live API Keys

Go to stripe account and make test mode off so you will get live Keys and implement that keys.

Note: Live key will use for the original transaction so be careful to make testing with a minimum amount for testing.
