Mitigating the Risks of Low Authorization Rates in Online Payments

As e-commerce continues to grow, efficient payment processing has become a key factor in business success. However, managing transactions can present several challenges, especially when it comes to authorization rates.

Authorization rates, which measure the percentage of approved transactions out of all attempts, are critical to the financial stability of any online business. When these rates are low, they can create serious risks. In this article, we'll explore the impact of low authorization rates and strategies to mitigate them.

Impact of low authorization rates

1. Lost sales and revenue

Every declined transaction represents a direct loss of revenue. Beyond the immediate impact, there are hidden costs such as customer acquisition expenses and marketing investments. In addition, every declined transaction is a missed opportunity to build customer loyalty and encourage future purchases.

2. Increased cart abandonment

Unexpected declines frustrate customers and may cause them to abandon their shopping carts. Studies have shown that payment issues are one of the main reasons consumers fail to complete online purchases, affecting both immediate sales and customer trust in the brand.

3. Poor customer experience

Frequent declines can make customers view your store as unreliable or insecure. To maintain consumer trust, you need to balance security with ease of use throughout the checkout process.

4. Reputational risk

When customers feel their transactions are being unfairly declined, they may lose trust in your company. Negative reviews and online comments can damage your business's reputation and discourage potential new customers.

Reasons for low payment authorization rates

1. Increased scrutiny from issuing banks

Issuing banks often monitor transactions closely, which can lead to unjustified declines and lower sales conversion.

2. Lack of trust between banks

Transactions depend on trust between issuing and acquiring banks. When this trust is low, decline rates increase, hindering e-commerce growth.

3. Friction in the checkout process

Differences in payment methods, currencies, and additional verification steps can make checkout complicated and unintuitive for customers. This friction increases the likelihood of purchase abandonment.

Strategies to improve online payment authorization rates

1. Implement fraud prevention measures

While security is crucial, it's important to balance it with the user experience. Advanced fraud management solutions can help prevent fraudulent transactions without negatively affecting the approval rate for legitimate payments.

2. Offer local payment methods

Allowing customers to pay with their preferred payment methods can make checkout smoother and more reliable. Adapting to different markets and diversifying payment options improves conversion and reduces friction.

3. Communicate costs transparently

Clearly communicating shipping costs and potential fees helps avoid unpleasant surprises that could lead to declined transactions. Cost transparency strengthens customer trust and improves conversion rates.

4. Build trust with customers

A secure website with SSL certificates, customer reviews, and trust seals can increase credibility and reduce perceived risk. A reliable payment platform also ensures data protection and dependable online transactions.

How Tilopay has solved the online payment authorization rate challenge

Tilopay has improved its transaction approval rate through a combination of payment routing optimization, real-time data analysis, integration with multiple acquirers, and advanced fraud prevention systems. 

Below, we break down the key technical aspects:

1. Smart Transaction Routing

• Tilopay uses an AI-powered routing engine to analyze every transaction in real time and route it to the acquirer or processor with the highest likelihood of approval.






• This system evaluates factors such as:
  
  
  
  • Acquirer success history based on region, issuing bank, and card type.
  
  

  
  

  • Acquirer load and latency, to avoid processors with slow response times or technical issues.
  
  

  
  

  • Strategic retries: If a transaction is declined, the system can automatically resubmit it to another acquirer using different parameters—for example, with a lower risk of being blocked due to suspected fraud.
  
  
  
  

2. Multi-acquirer processing and processor aggregation

• Tilopay doesn't rely on a single acquirer. Instead, it connects to multiple payment gateways and acquiring banks.






• This means that if one processor declines a transaction, it can be rerouted to another without requiring the user to retry manually.






• It also enables businesses to operate in different markets without being limited by a single provider's restrictions.

3. Machine learning and real-time data analysis

• Machine learning models are used to identify approval and decline patterns based on:
  
  
  
  • The buyer's geographic location.
  
  

  
  

  • Card type (debit/credit/prepaid) and issuing bank.
  
  

  
  

  • The user's purchase history.
  
  

  
  

  • Merchant characteristics and the industry in which it operates.
  
  
  
  






• These models dynamically adjust routing parameters to improve the approval rate.

4. Fraud prevention with AI and Adaptive Risk Scoring

• Tilopay uses AI-powered fraud detection systems that evaluate every transaction before sending it to the acquirer.






• It implements an adaptive risk scoring system (Adaptive Risk Scoring) that classifies transactions based on how likely they are to be fraudulent.






• If a transaction has a high risk score, the system can request additional authentication—3D Secure 2.0, biometrics, or dynamic tokenization—instead of declining it immediately.

5. Tokenization and reduced checkout friction

• Tilopay uses card tokenization to securely store payment data and reduce security-related declines.






• It implements network tokens compatible with Visa and Mastercard, reducing the percentage of declines caused by changes to card credentials.






• It optimizes payment flows with frictionless authentication (Frictionless 3D Secure), improving the user experience and reducing unnecessary declines.

6. Authentication optimization and regulatory compliance

• Tilopay complies with standards such as PCI DSS, PSD2 (in Europe), and 3D Secure 2.0, which improve security without affecting the approval rate.






• It offers adaptive authentication methods, allowing certain low-risk transactions to be exempt from additional authentication.

Expected results

With these strategies, Tilopay achieves:

• Fewer fraud-related declines thanks to its real-time risk assessment system.






• Higher conversion for international payments by working with multiple acquirers.






• Less friction for legitimate users, improving the shopping experience and increasing the approval rate without compromising security.

In short, Tilopay maximizes payment processing efficiency through a combination of smart routing, predictive analytics, AI-powered fraud prevention, and authentication optimization, enabling significantly higher approval rates than traditional gateways.

Conclusion

Authorization rates are a key factor in e-commerce success. By understanding the risks associated with low rates and applying effective strategies, your business can increase sales and strengthen customer satisfaction.

In this context, solutions such as Tilopay offer smart routing technology, fraud prevention, and support for multiple payment methods, optimizing authorization rates and improving the user experience.
