Mercury Open Banking FAQ

To integrate with Mercury, visit their developer portal to register for API access. You'll typically need to create a developer account, obtain API credentials, and test in their sandbox environment before going live. Alternatively, use an API aggregator for faster integration.
PSD2 compliance depends on Mercury's operating jurisdiction. European banks must comply with PSD2, while banks in other regions follow their local Open Banking regulations. Check the compliance section above for specific certifications.
