Absolutely – yes!

At CartDNA, we welcome and actively support requests for integrating new payment methods into Shopify, even if they’re not currently listed on our website.

We pride ourselves on a fast turnaround time to get new payment gateways integrated and approved by Shopify.

If you can’t find the payment method you need, please contact our customer service — we’re happy to assist and can integrate it with Shopify for you.

1. Developer API Documentation
Complete technical documentation for the payment gateway’s API is required. This should include:

API endpoint references

Authentication mechanisms

Callback/Webhook information

SDKs (if applicable)

Any other relevant integration guides or technical specs

2. Sandbox or Test Merchant Credentials
We need access to a test environment or sandbox account, along with test credentials, so we can properly test the integration without initiating real transactions.

3. Testing Tools & Simulators
Please provide:

Test cards or virtual payment methods

A testing guide

Any sandbox simulators or tools that help us test payments, refunds, and failure scenarios

4. Reason for Requesting This Payment Method
It’s helpful for us to understand why you want this payment method integrated. Some common reasons include:

Shopify Payments isn’t available in your country

Lack of local payment options through Shopify

You already use this payment processor and trust their service

Easier merchant onboarding or better approval process

Stronger dispute/chargeback handling

Faster payout/settlement cycles

Regulatory compliance requirements

Preferred customer service or after-sales support

More flexible transaction capabilities

5. Any Customisation Requirements
Let us know if you have specific needs, such as:

Multicurrency support

Shopify Markets compatibility

Language localisation

A simplified customer payment experience

Additional fraud protection or KYC features

UI/UX customisations

Payment method branding

Integration with other apps or platforms

As a certified Shopify Payment App Developer, CartDNA strictly follows Shopify’s guidelines and best practices to ensure secure, compliant, and high-quality integrations.
Before you commit, we provide you with a test version of the payment app. This allows you to:

Test the full integration

Validate that it meets your expectations

Test the application in a real Shopify environment to ensure it works seamlessly with other Shopify apps.

Only once you’re satisfied and the app is approved, do you move forward with the licensing agreement with CartDNA.
