Before you can accept any form of payment, you need to create a merchant account with your preferred payment gateway. This typically entails the following:
Creating an account on the gateway’s platform
Providing the necessary business information
Undergoing some verification process
2. Get API Keys and SDKs
API keys are the unique identifiers that will give your app secure access to the payment gateway. Once your merchant account is set up, you will get those keys. Most gateways also supply SDKs, which are easier to integrate.
3. Design the Payment Flow
Design how the payment will work in your application. Consider where and when the payment options will be shown; and how the users will input their payment information.
What the confirmation process will look like
4. Integrate the Payment Gateway SDK
Integrate the SDK that comes from the payment gateway within your application code. Normally, this would include:
- Adding the SDK to your project
- Initializing the SDK by using API keys
- Create methods to handle the processing of payments
5. Set up a Server-side Component
For added security, one should integrate a server-side component in their application, which is responsible for interacting with the payment gateway. This ensures that none of this sensitive information would sit on the client’s side. Your server should be able to:
a) receive payment information from the app
b) Interact with the payment gateway regarding the processing of the payment.
c) send confirmation back to the app.
6. Implement Client-side Logic

Collect the user’s payment information.
Send the data securely to your server
Deal with the response – succeeded, failed, etc.
Update the UI
7. Test the Integration
Aggressively test your payment integration for correctness. The majority of the payment gateways allow a sandbox where you can test your integration without any real transactions taking place.
8. Errors and Corner Cases Handling
Consider multiple scenarios and include respective error handling:
Network issues
Invalid payment details
Insufficient balance
Transaction cancelled

- Advise how any issues can be resolved
- Provide retry or save for later for failed payments
4. Use Strong Authentication
- Implement two-factor authentication for large-value transactions
- Avail Biometric authentication options whenever available, face ID
5. Clearly Document
- Make payment and refund policy information easily accessible
- Provide crystal clear instructions on how to use each of the different payment options
6. Transaction Tracking and Analysis
- Log all transactions to track transaction details
Frequently review the transaction data for any patterns or inconsistencies
7. Compliant with Regulations
- Take into consideration evolving payment regulations in the concerned target countries/regions.
- Conduct an audit of payment processes at a certain period to maintain compliance.
