How to Accept Credit Card Payments Worldwide and Reduce False Declines

Managing payment systems across multiple markets creates operational complexity that can further impact your conversion rates and sales performance.

5 Steps to Accept Credit Card Payments Online With Rapyd

Follow these five steps to begin accepting credit card payments online with higher authorisation rates and comprehensive global coverage.

Step 1: Review Business Requirements

Estimated completion time: 10 minutes

Check our prohibited and restricted businesses list to confirm we can support your specific industry and business model.

  • If your business is on the restricted list, you’ll need additional documentation
  • Certain high-opportunity industries may require more comprehensive verification
  • Regulated industries like financial services need specific licensing information

If you’re on the restricted list, we may be able to help but additional review and verification is required. 

Step 2: Contact Our Team

Estimated completion time: 15 minutes

Contact us to discuss your specific payment needs and requirements.

  • Include details about your industry and business model
  • Specify your expected monthly processing volume
  • Describe your primary markets and payment method requirements
  • Mention any specific integration preferences or technical needs

Our payment specialists will review your information and guide you through the next steps tailored to your business requirements.

Step 3: Create Your Rapyd Account

Estimated completion time: 15-30 minutes

Create your account to access the Rapyd Client Portal and begin your integration:

  • Sandbox Environment: Begin with Sandbox mode to test integrations without processing real transactions
  • Production Environment: Once testing is complete, you’ll transition to the Production environment
  • API Keys: Generate secure API keys for both Sandbox and Production environments
  • Developer Documentation: Access comprehensive integration guides and API reference materials

The Sandbox environment perfectly mirrors Production, allowing you to test your full payment flow before going live. Toggle between environments directly in the Client Portal.

Step 4: Complete KYB Application

Estimated completion time: 30-60 minutes (plus review period)

KYB (Know Your Business) is the process where we verify your business identity to comply with financial regulations. Complete your KYB application by clicking “Activate Account” in the Client Portal.

Required documentation includes:

  • Business registration documents
  • Proof of business address (utility bill or bank statement)
  • Director/owner identification documents
  • Beneficial owner information for any person owning 25%+ of the business
  • Bank account details for settlements

Processing times vary by business type and region. Many businesses are processed in under 24 hours. Our compliance team will guide you through any additional requirements based on your specific business profile.

Step 5: Start Accepting Payments

Estimated completion time: 1-3 days for implementation

Once your KYB verification is complete, you can begin accepting payments worldwide through multiple integration options:

  • API integration: Comprehensive API for custom checkout experiences and full control over the payment flow. Integrate Rapyd into your websites, applications and workflows and create unique commerce experiences.
  • Hosted checkout: Pre-built checkout page with your branding that handles the entire payment process. Shoppers are redirected to a Rapyd checkout page with your business’s branding. It’s an easy way to accept payments without managing payment infrastructure.
  • Developer toolkit: Toolkit for creating customised checkout experiences and adding our Hosted Checkout to your website via iFrame while maintaining PCI compliance. Platform plugins: Ready-made integrations for WooCommerce, Shopify and other ecommerce platforms.
  • Virtual terminal: Web-based terminal for accepting payments over the phone or in person.
