‍

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

1. Data mapping and standardization

‍

Ensuring accurate data transfer between systems is key to avoiding errors and inefficiencies.

• Standardize date formats (e.g., YYYY-MM-DD), currency formats, and text fields.
• Remove duplicates, correct errors, and ensure consistency before integration.
• Standardize customer information, such as addresses, names, and verification details.
• Ensure numerical data, text fields, and records follow uniform structures 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.

“We recommend going beyond basic SSL/TLS and access control by implementing a multi-layered security system with modern solutions. This includes two-factor authentication with hardware keys or biometrics and strong database encryption for data storage. Additionally, set up DLP (Data Loss Prevention) systems to prevent confidential data leaks. And don’t forget about compliance—automate checks for GDPR, CCPA, and PCI DSS to stay secure and compliant effortlessly", adds Vlad Petrovych.

‍

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.

Technical considerations on the implementation depending on the banking system type

When integrating a banking system with Salesforce, technical specifics matter. Different systems have unique requirements and limitations. Legacy systems may require extra effort to ensure compatibility with modern CRMs, leading to delays and higher costs. Meanwhile, modern platforms often support APIs, making integration smoother and data access faster. A well-planned integration prevents data issues, enhances system interaction, and ultimately improves customer service and operational efficiency.

‍

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.
