Here’s a step-by-step explanation of how open banking API integration typically works:
- Customer Consent: The process begins with the customer giving explicit consent to a third-party provider to access their bank data. This consent is crucial and regulated to ensure privacy and security.
- API Request: After receiving consent, the third-party provider submits an API request to the customer’s bank. This request specifies the data or services they need to access.
- Authentication and Authorization: The bank authenticates the third-party provider and verifies the customer’s consent. This is critical for security and ensures only legitimate requests are processed.
- Data Sharing: Upon successful authentication, the bank shares the requested data with the third-party provider through the API. This data could include transaction history, account balances, or other relevant information.
- Service Delivery: The third-party provider uses the accessed data to deliver innovative financial services to the customer. These services can range from budgeting apps and payment services to personalized financial advice.
