We have official plugins and integrations for Shopify, WooCommerce, PrestaShop, Magento (2.x and 1.9), OpenCart, Shopware, nopCommerce, Drupal Commerce, modified eCommerce, and osCommerce. Wix and Ecwid integrations are currently in development. If your platform is not listed, you can integrate using our REST API and Hosted Payment Page.

Log into the Merchant Portal at dashboard.costplus.io. Navigate to Websites, select your website, and click Integration. Your API key and Merchant ID are displayed there. Keep your API key secure and never expose it in client-side code or public repositories.

No. There is no separate sandbox URL. You use the same API endpoint (https://api.costplus.online/v1/) for both sandbox and production. The mode is determined entirely by the website type in the Merchant Portal, not by the URL. Use a sandbox website's API key for testing and a production website's API key for live transactions.

The Merchant Portal at dashboard.costplus.io is your central hub for managing Cost+ payments. Here you can create and manage websites, view transactions, access API keys, configure payment methods, set up webhooks, and monitor your payment activity. Sign up for free at dashboard.costplus.io/register.

Yes. Cost+ offers SDKs and client libraries for Node.js/TypeScript, Python, PHP, Java/Kotlin, C#/.NET, and Ruby. These simplify API integration by handling authentication, request formatting, and response parsing. See docs.costplus.io for installation and usage instructions.

The collaborator request access code is a 4-digit code that lets you grant Cost+ access to your Shopify store. Here is how to find it:

1. Log in to your Shopify store admin panel.
2. Click "Settings" in the bottom left corner.
3. Select "Users" from the settings menu.
4. Scroll down to the "Collaborators" section.
5. You will see the 4-digit access code displayed there.
6. Click the icon next to the code to copy it.

Send the code along with your webshop URL to onboarding@costplus.io, or fill it in on the form you received in your order confirmation.

If you cannot find the code, make sure your user account has the right permissions in Shopify.

To let Cost+ install and configure the WooCommerce plugin, create a temporary admin user:

1. Log in to your WordPress dashboard at yourdomain.com/wp-admin.
2. Go to Users, then Add New.
3. Fill in the details: Username "nopayn", Email "onboarding@costplus.io", First Name "Cost+", Last Name "Support", Password (use Generate Password for a strong one), check "Send User Notification", and set Role to "Administrator".
4. Click "Add New User".
5. Email onboarding@costplus.io to let us know the account is ready.

Important: Remember to remove this user account once we have completed the installation. The temporary admin account will only be used for plugin installation and configuration.
