FAQ
What information do I need to provide?
Please provide the target App name, specific function points (such as account inquiries, transaction history, payments, Webhook, etc.) and the authorization method (developer account, API key, test account, etc.). If there are compliance or regional restrictions, please describe them as well.
Do you support multi-language and localization access?
Yes. We will consider multi-language error messages, time zone conversions, and local compliance requirements (for example PSD2, SCA, local AML rules).
Can the delivered interfaces be deployed to production?
Delivery includes runnable samples, test cases, and deployment instructions; typically can be verified in the client environment with minimal configuration and put into pilot deployment.
