Increasingly, business is conducted on the Internet, and billing for services and goods is done remotely. After the Covid-19 pandemic, this trend became even stronger and most companies chose the direction of digitization and automation of their sales processes. So, can we use a low-code platform such as Oracle APEX to build a solution that will allow us to make remote payments for services or goods offered by the client?

Yes, we can – and in this article, I’ll show you precisely how to integrate the Stripe system with an Oracle APEX application. To prepare such a solution, we will use the standard, built-in Oracle APEX functionalities and rely on the API documentation of the Stripe platform. To achieve the desired result, we’ll need to make a few steps:

  1. Plan the system’s structure
  2. Create an integration for products
  3. Create an integration for customers
  4. Create an integration for building the payment page

Besides taking you through these steps, I’ll also share some useful tips and tricks you can use in such a project.

Planning the structure of our system

First, let’s look at the assets I’ll use in my example. The whole project is based on three tables: TBL_PRODUCTS, TBL_CUSTOMERS, and TBL_BUCKET.

APEX and Stripe – product integration

The structure of the Stripe system requires the creation of products and prices for them – separately – and then binding two objects together.

So, first of all, we need to prepare a process that will be responsible for adding an article (product) to the Stripe system. Then, we will add a price to that article in the Stripe system, and in the last step we will save this data along with the new article in the local database, linking it together.

To add a new product, a new “create” process needs to be added to the system. Its task will be to handle adding new products.

As part of that process, we first need to send the authorization to the Stripe server:

apex_web_service.g_request_headers(1).name := ‘Authorization’;
apex_web_service.g_request_headers(1).value := “Bearer sk_test_51KhDwDAQ9dGIwijiBM3f6S

Then, we have to prepare an API request that will be responsible for sending information to the Stripe server with a request to create a new product. It will return a response containing the product ID on the Stripe website.

    p_url => ‘’,
    p_http_method => ‘POST’,
    p_parm_name => apex_util.string_to_table(‘name:description’),
    p_parm_name => apex_util.string_to_table(:P7_NAME| |’:’| |:P7_DESC)

After sending the information, our task is to receive the answer and search for information about the new object ID in the Stripe service.

v_id_new_prod_stripe := apex_json.get_varchar2(p_path => ‘id’);

After saving the identifier in the variable, we can add the price for our product in the Stripe system. The process is similar to the one described above, but we can skip the authorization sent to the server in this session and go straight to sending the request:

    p_url => ‘’
    p_http_method => ‘POST’
    p_parm_name => apex_util.string_to_table(‘unit_amount:currency:product’),
    p_parm_value => apex_util.string_to_table(:P7_PRICE*100| |’:’| |:P7_CURRENCY| |’:’| |v_id_new_prod_stripe)

In response to the above query to the Stripe server, we will receive information about the ID of the price newly added to the product. One important thing: when sending a request assuming a price, multiply its value by 100. To read the ID of a new price, you need to parse the response and save the value to a variable, which you then save in the local database.

v_id_new_price_stripe := apex_json.get_varchar2(p_path => ‘id’);

VALUES (SEQ_PROD_ID.nextval, :P7_NAME, :P7_CURRENCY, :P7_PRICE,v_id_new_prod_stripe, v_id_new_price_stripe, :P7_DESC );

Integrating customers

Integrating customers is done in the same way as adding products. First, you need to create a new page in APEX and add a process to it, which will be responsible for adding new customers in the Stripe system, and in local database.

Integrating customers.

The first step is to resend the authorization to the Stripe server, in the same way as when adding products.

Then, using the process below, we will add a new customer to the Stripe system, read the identifier and save it in the local database.

    p_url => ‘’,
    p_http_method => ‘POST’,
    p_parm_name => apex_util.string_to_table(‘description:email:name:phone’),
    p_parm_value => apex_util.string_to_table(:P9_DESCRIPTION| |’:’| |:P9_EMAIL| |’:’| |:P9_NAME| |’:’| |:P9_PHONE)
v_id_new_cust_stripe := apex_json.get_varchar2(p_path => ‘id’);

VALUES(:P9_NAME, :P9_DESCRIPTION, :P9_EMAIL, :P9_PHONE, v_id_new_cust_stripe);

Creating a new shopping session

To add a new shopping session, it is necessary to create a new website similar to an online store. To create such a page I used the “CARD” control with the following configuration:


Stripe checkout.Next, we have to add a process that will complete the said basket the user selected items from the list.


The last step in creating a payment session is generating a process that sends a request to the server. We’ll receive a link with the payment page in response.

I linked the above-mentioned process to the “PAY” button:

Pay button.

How to create the process in five steps

The process consists of five main steps:

  • Sending authorization to the server – this is done in exactly the same way as for products and clients
  • Preparing a list with parameters

If we have more than one product in the basket, we have to prepare a couple of variables for the names and prices of the parameters and for the values assigned to them:

v_clob_checkout varchar2(32000);

v_param_name_list varchar2(250);
v_param_name_list := v_param_name_list| |’:line_items[‘| |v_list_item_number| |’][price]:line_items[‘| |v_list_item_number| |’] [quantity]’;
v_param_value_list := v_param_value_list| |’^’| |x.ARTICLE_PRICE_ID| |’^’| |x.QUANTITY;
v_list_item_number := v_list_item_number + 1;
end loop;
  • Preparing a request to the server 

We need to prepare a request to the server. This is how you do it:


p_url => ‘’,

p_http_method => ‘POST’,

p_parm_name => apex_util.string_to_table(‘success_url:cancel_url:mode’| |v_param_name_list),

p_parm_value => apex_util.string_to_table(‘https:/^^paymanet’| |v_param_value_list, ‘^’)


When preparing such a request, we should also remember about parameters such as “Success_url” and “Cancel_url”. These are the addresses of the pages to which you will be redirected in the event of either a positive payment, or resignation.

  • Receiving the URL from the payment page

In response for that request, we’ll receive the URL address of the payment page.


v_url_checkout := apex_json.get_varchar2(p_path => ‘url’);
  • Opening the payment page

The last step is opening our payment page.

apex_util.redirect_url (  p_url => v_url_checkout);


How the process looks from the user interface side

Here’s how the payment process looks for the end-user.

Payment process.

After selecting the “pay” button (“Zapłać”, to be precise, as Stripe recognizes that I’m in Poland, and shows me the Polish interface) , the system will redirect the user to the “Success_url” page and clean the basket.

Successful payment.

In the event of non-payment, the user will be redirected to the “Cancel_url” page and the basket will remain unchanged.

Unsuccessful payment.

Tips and tricks

Before I end this article, I’d like to share a few pieces of advice, and simple tricks I often use in my day-to-day work.

  1. When building a token for authorization, remember to enter Bearer for the token value, e.g. apex_web_service.g_request_headers (1) .value: = ‘Bearer / token /’
  2. When creating a request to build a session for payment, remember to use the https: // prefix for website addresses. When you create the payment page and build a list of parameters and values for them, replace the parameter separation sign “:” with another, e.g. “^”


And that’s it. I hope you’ve learned a little bit about integrating Stripe with Oracle APEX – as you can see, it’s quite easy to do. If you remember a few simple rules and follow the steps outlined in this article, you can have a fully functional payment system in your project in no time. That’s what low-code is all about, isn’t it?
