Connect Shopify to your CardCorp payment gateway with Chopify.

Prerequisites

Request your CardCorp payment gateway authentication credentials (Entity ID and Access Token) from the CardCorp Support Team. CardCorp provides separate access tokens for the test and live environments.
Use the Shopify Basic plan or higher for your store.

Create a custom app in Shopify

Create a custom app in Shopify for the Chopify connector.

Sign in to Shopify at https://admin.shopify.com/.
In the left sidebar, near the bottom of the page, select Settings.
Select Apps, then Develop apps.
Select Build Apps in Dev Dashboard.
Select Create app.
Under Start from Dev Dashboard, enter the App name, then select Create.
For the App URL, enter https://[subdomain].chopify.pro and replace [subdomain] with your store subdomain, for example, https://npv3yt-vu.chopify.pro.
For the Webhooks API version, select 2026-01.

For the Scopes, paste these values.

For the Subpath prefix, enter cardcorp-checkout.
Set the Proxy URL to https://[subdomain].chopify.pro/proxy/cardcorp-checkout.
Select Release, then confirm your app details for this version. If you need to change something, create a new version.

Get the app credentials

In Settings, copy the Client ID and Secret. Send these credentials to CardCorp Merchant Services.

Install the app

Go to Settings > Apps. Select Develop apps, then select Build Apps in Dev Dashboard.
Select the App, then select Install app.

CardCorp Merchant Services creates your connection

CardCorp Merchant Services registers your app credentials on the server before you configure the Chopify app. Confirm that registration is complete before you continue.

Configure the Chopify app for the test environment

Configure the Chopify app with your test credentials before you deploy it to your live store.

In Shopify Admin, go to Apps.
Select your app name, then select Settings.
Enter your Entity ID and Access Token for your test environment.
Clear the AMEX brand because that requires a separate connector in the gateway.
For Test Mode, select EXTERNAL.
Optional: Select Enable card registration to let your customers save cards.
For Deployment method, select Theme Asset, then select your Target theme.
Click Save.
Select Test connection and confirm that your credentials work. If the credentials do not work, confirm that CardCorp Merchant Services has registered your app credentials.
Select Deploy script.

Configure the Chopify app for the live environment

Configure the app with your live credentials to accept payments from your customers.

Go to Shopify Admin.
Select your app name, then click Settings.
Enter your Access Token for the live environment.
For the Base URL, enter https://eu-prod.oppwa.com to use the live environment.
For Test Mode, select None (Production).
Click Save.
Click Remove script. After Shopify removes the script, click Deploy script.

Chopify supports delivery to the customer's shipping address only. Selecting additional delivery methods does not make them available to the customer.
