The time it takes to move to production varies. Factors that influence the length of time include: the type of use case, resources available, and the complexity of the service being delivered to customers.
At a high level, our security assessment will evaluate the following:
Infrastructure – The physical structures, IT, and other hardware your company uses.
Software – Your company’s application programs and IT system software.
People – The personnel involved in the governance, operation, and use of a system.
Procedure – The organizational protocols and automated or manual procedures.
Data – Transaction streams, files, databases, tables, and output used or processed by a system.
The security assessment will be conducted by Citi’s Information Security Group. In some situations, a SOC 2 audit report conducted by an independent, certified auditor in the last 12 months can be used to supplement the information we require in the security assement. Please note that the security assessment will have to be updated on an annual basis or if there are any material changes.
- Timing: The assessment process takes appoximately 2 to 3 weeks, depending on the completeness of the material you provide, any gaps we might identify and the availability of resources.
- In the agreement you enter into with Citi, Citi will reserve the right to conduct an audit on demand in certain situations such as:
1. Data breach or fraudulent access
2. Misuse or mishandling of data
3. Failures in security infrastructure and controls
4. Regulatory expectations
5. Any events that could potentially impact Citi Customers (e.g., If a Citi
Customer’s sensitive non-Citi account information has been breached)
Yes. Citi is compliant with PSD2 in the markets where it is applicable.
The Citi customer data fields available through our APIs are those shown in our Developer Hub API Catalog. As described in the Catalog, the customer data fields vary based on the market location of each API. In some situations, we might make additional customer data fields available when a use-case has a compelling customer value proposition.
Before you can use a Citi customer’s data, you must first obtain explicit consent from the customer, and the way in which you use that data must comply with the terms of the agreement you enter into with Citi.
The cost of accessing production APIs depends on the specific use case, which APIs you access, traffic volume, and your business case to Citi customers. Note that the sandbox can be accessed by anyone registered on Developer Hub without any fees.
