Salesforce integration for banks and financial institutions

How to connect a banking system with Salesforce CRM in 5 steps

1. Data mapping and standardization

This step is crucial to ensuring that information is accurately transferred between systems. Data can become misaligned without proper mapping, leading to errors and inefficiencies. 

There are several approaches to data standardization.

First, you must ensure that both systems use the same data field formats. For example, standardize date formats (e.g., YYYY-MM-DD), currency formats, and text fields. Before integration, clean your data to remove duplicates, correct errors, and ensure consistency. This might involve normalizing address formats, standardizing names, and verifying customer information. Finally, ensure that numerical data, text fields, and other data types are consistently defined across both systems.

2. Considering secure data transfer

You need to take several measures to protect sensitive banking and customer information. Encryption protocols such as SSL/TLS ensure data is securely transmitted over the network. Implement authentication security measures so only authorized systems and users can access the data. Ensure that the data transfer methods comply with relevant regulations, such as GDPR, CCPA, or PCI DSS, to avoid legal and financial penalties.

3. Testing and validation

Before fully deploying the integration, it's essential to precisely test and validate the system to ensure it functions correctly. Consider to perform the following tests:

  • Conduct tests to ensure data transfers accurately between the banking system and Salesforce. This includes verifying that all data fields are correctly mapped and transferred without errors.
  • Test all functions used in the integrated system, such as data updates, queries, and reporting.
  • Assess the system's performance to ensure it can handle the expected load without issues.
  • Perform user acceptance testing to ensure the system meets the needs and is easy to use.

4. Deployment

Deployment involves rolling out the integration to your live environment. There are two main approaches:

  • Phased rollout. Gradually deploy the integration to different segments of your organization. This allows you to manage risks and address issues in smaller, controlled stages.
  • Full Implementation. Deploy the integration across the entire organization at once. This can be faster but carries more risk, as any issues will affect the whole system simultaneously.

5. Maintenance

Ongoing supervision is necessary to ensure the integration remains functional and up-to-date. Monitor the system regularly to identify and resolve issues promptly. This includes tracking data transfer logs and system performance. Update the integration components, including any custom code, pre-built connectors, or APIs, to address security vulnerabilities and improve functionality. Continuously gather user feedback to identify improvement areas and ensure the integration meets their evolving needs. Maintain comprehensive documentation of the integration process, configurations, and any changes made. This helps in troubleshooting and future upgrades.

Technical considerations on the implementation depending on the banking system type

Core banking systems (CBS)

Most core banking systems offer APIs for data exchange. Identify the specific API versions and functionalities your CBS supports to ensure compatibility with Salesforce for banking. After reviewing the API documentation provided by your CBS, you will be able to review available endpoints, request and response formats, and rate limits.

Security is crucial in this context. Many modern APIs use OAuth for secure authorization, so ensure your integration supports OAuth flows to protect sensitive data. If your CBS uses token-based authentication, verify this and implement secure token handling practices to maintain data security.

Legacy systems

Integration with legacy systems often requires custom development or data extraction tools to bridge the gap between older systems and Salesforce CRM. This might involve writing custom scripts or using middleware to facilitate data exchange. Using ETL (Extract, Transform, Load) tools can automate data extraction, transformation, and loading processes.

Data mapping and standardization become even more crucial when dealing with legacy system data formats. Legacy systems often use outdated or proprietary data formats, so thorough data mapping and standardization are essential to ensure accurate and consistent data transfer. When dealing with legacy data, consider data cleansing to remove inconsistencies and errors.

Cloud-based banking systems

Cloud-based banking systems often provide pre-built connectors or integration tools that simplify the integration process with Salesforce CRM. Leveraging support from your cloud banking system vendor can help configure and deploy these connectors.

Cloud platforms offer features like data warehousing and managed APIs that can streamline data exchange. Cloud-based data warehousing solutions that aggregate and manage data from various sources before integrating with Salesforce CRM can enhance data management and reporting capabilities. Use your cloud banking system's managed APIs to facilitate seamless and secure data exchange with Salesforce.
