Integrating payments with Stripe is easy. You would need a quick registration on http://www.stripe.com, after which you can use the test version of the Stripe API until your web app is deployed and the live version afterwards. Stripe is responsible for processing and keeping clients’ credit/debit card data so no information of essence would be stored on your server and you would not have to comply with all the rules that come with storing credit/debit cards.
First, we install stripe library using composer, next step we creating stripe gateway library in codeigniter.
