Seeking Developer with Recent Experience Integrating NOWPayments on Shopify Checkout Page

Shopify Apps
,

Topic summary

A store owner is seeking a developer to integrate NOWPayments API into their Shopify checkout page for cryptocurrency payments. The desired features include:

  • Adding a “Pay with Crypto” checkout option
  • Dynamic cart total retrieval
  • Webhook callback setup for payment confirmation and order processing
  • Custom button styling to match store aesthetics

The store sells adult wellness products, making high-risk eCommerce experience valuable.

Key Technical Constraint Raised:

A community member pointed out that Shopify doesn’t permit custom payment API integrations into native checkout—even on Shopify Plus—unless the provider is officially approved. NOWPayments may not be on Shopify’s approved payment gateway list.

Suggested Alternative:

Use officially approved crypto payment providers like Coinbase Commerce, BitPay, or Crypto.com, which can be properly integrated within Shopify’s framework.

Status: The discussion remains open, with the original poster yet to respond to the technical limitation identified.

Hi all,

I’m looking for a developer with specific, recent experience integrating the NOWPayments API into a Shopify checkout page.

I already have a NOWPayments account and API key. My goal is to:

  • Add a “Pay with Crypto” option to the checkout page
  • Ensure it dynamically grabs the cart total at checkout
  • Set up the webhook callback to confirm payment and trigger order processing
  • Match the button styling to my store’s minimalist aesthetic

My store specializes in adult wellness products, so familiarity with high-risk eCommerce is a bonus.

If you’ve implemented this exact integration recently, especially on Shopify, I’d love to hear from you. Please feel free to share any relevant examples or references.

Thank you,

Rowan

Hi @IRedefined ,

Just wanted to share a few key points that might help before you dive into the integration:

  1. Check if NOWPayments is a Shopify-approved payment provider
    You can verify here: https://www.shopify.com/payment-gateways

  2. Even on Shopify Plus, you can’t integrate your own payment API
    Shopify doesn’t allow injecting custom payment providers into the native checkout unless they’re officially listed.

  3. Your best option is to use a listed crypto provider
    Providers like Coinbase Commerce, BitPay, and Crypto.com are already approved and can be integrated properly.

Let me know if you want help exploring those options or setting one up.
