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 | |||
92.1 | 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]]. | |
91.1 | 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 | |||
100.1 | 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. | |
91.1 | 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 | |||
100.1 | 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. | |
91.1 | 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}} | ||
83 | |||
