| 2 | == Add JavaScript reference == |
| 3 | |
| 4 | Before implementing PayEx Checkout on your web site, you need to add a reference to the PayEx Checkout script to your page: |
| 5 | |
| 6 | {{code language="html"}} |
| 7 | <script src="https://checkout.payex.com/js/payex-checkout.min.js"></script> |
| 8 | {{/code}} |
| 9 | |
| 10 | Please note that the above URL points to **PayEx Checkout's production environment**. If you want to integrate with PayEx' test environment, [[please refer to the FAQ for the correct URLs>>doc:Main.ECommerce.PayEx Checkout.FAQ.WebHome]]. |
| 11 | |
| 12 | == Basic usage == |
| 13 | |
| 14 | The simplest way to implement PayEx Checkout in your frontend is with the {{code}}data-payex-checkout{{/code}} attribute. |
| 15 | |
| 16 | Choose the button you want to open the PayEx Checkout modal and add the attribute {{code}}data-payex-checkout{{/code}} with the value returned {{code}}paymentSessionUrl{{/code}} from the [[initial POST>>doc:Sandbox.payex-checkout-v1.WebHome||anchor="HStep1:Createpaymentsession"]]. Then add the {{code}}disable{{/code}} attribute - the PayEx Checkout script will enable it when it is properly loaded. The button should be wrapped inside a form that posts to your server. |
| 17 | |
| 18 | The PayEx Checkout script will submit the {{code}}<form>{{/code}} when the PayEx Checkout user flow is complete. |
| 19 | |
| 20 | HTML |
| 21 | |
| 22 | {{code language="html"}} |
| 23 | <form action="<url_to_your_server>" method="post"> |
| 24 | <!-- ... --> |
| 25 | <button data-payex-checkout="<payment_session_url>" disabled>Pay</button> |
| 26 | </form> |
| 27 | {{/code}} |
| 28 | |
| 29 | == Basic usage with options == |
| 30 | |
| 31 | (% id="H" %) |
| 32 | The PayEx Checkout script can be configured with options to get callbacks on certain events in the checkout user flow. |
| 33 | |
| 34 | Availialbe callbacks: |
| 35 | |
| 36 | * {{code}}onOpen{{/code}} // - Callback called when the PayEx Checkout modal is opened.// |
| 37 | * {{code}}onClose{{/code}} // - Callback called when the PayEx Checkout modal is closed.// |
| 38 | * {{code}}onError{{/code}} //- Callback called when PayEx Checkout is unable to open or complete a session.// |
| 39 | * {{code}}onComplete{{/code}} // - Callback called when PayEx Checkout user flow is completed.// |
| 40 | |
| 41 | HTML |
| 42 | |
| 43 | {{code language="html"}} |
| 44 | <form action="<url_to_your_server>"> |
| 45 | <!-- ... --> |
| 46 | <button data-payex-checkout="<payment_session_url>" disabled>Pay</button> |
| 47 | </form> |
| 48 | {{/code}} |
| 49 | |
| 50 | JavaScript |
| 51 | |
| 52 | {{code language="JavaScript"}} |
| 53 | payex.checkout("<payment_session_url>", { |
| 54 | onClose: function(){ |
| 55 | console.log("The modal was closed"); |
| 56 | } |
| 57 | }); |
| 58 | |
| 59 | {{/code}} |
| 60 | |
| 61 | == Flexibility usage == |
| 62 | |
| 63 | If you need more flexibility in your frontend, you can open the PayEx Checkout modal and post to your server programmatically. |
| 64 | |
| 65 | If you have added it, start by removing the {{code}}data-payex-checkout{{/code}} attribute to prevent the PayEx Checkout script to open and post automatically. |
| 66 | |
| 67 | You can open the checkout modal on demand with the {{code}}"open"{{/code}} argument and use the {{code}}onComplete{{/code}} callback to post to your server when the PayEx Checkout user flow is completed to continue with the [[Get Payment Status>>doc:Sandbox.payex-checkout-v1.WebHome||anchor="HStep4:Getpaymentstatus"]] step. |
| 68 | |
| 69 | Please note that Checkout must be opened with a [[trusted context>>https://developer.mozilla.org/en-US/docs/Web/API/Event/isTrusted]] in order to prevent pop-up blockers. The code has a trusted context when it runs as result of an user action. Code running within async callbacks such as ajax and timeout loses trusted context, so make sure you have acquired a payment session url before the user click on your buy button. |
| 70 | |
| 71 | |
| 72 | JavaScript |
| 73 | |
| 74 | {{code language="JavaScript"}} |
| 75 | // Remember to remove the data-payex-checkout attribute if you implemented it. |
| 76 | |
| 77 | payex.checkout("<payment_session_url>", { |
| 78 | onComplete: function() { |
| 79 | // Post or send a ajax request to your server to get the payment status step |
| 80 | } |
| 81 | }, "open"); |
| 82 | {{/code}} |
