    What are Contis APIs?

    Contis provides a complete PCI DSS Level 1 compliant banking and payment platform for companies that need some or all the elements of a banking solution to bring their own products to market. You can access our platform and services using our Contis APIs.

    What are the different API environments in Contis?

    Sandbox and Production

    What is Sandbox?

    Sandbox is a development environment in which you can thoroughly test your code before taking your integration live.

    What are disadvantages of Sandbox?

    Occasional patching and new code testing causes frequent downtime in the Sandbox. As Sandbox is an elementary testing environment it does not support urgent hot fixes.

    Do I need VPN for Sandbox?

    No. Unlike the Production environment you do not need a VPN connection to access the Sandbox.

    What is the Production environment?

    In Production environment you run your live system. You can make code changes using Urgent Hot Fixes. Disaster Recovery is also available in this environment.

    The card used is genuine and live transactions happen. This Production environment requires a different VPN setup.

    How do I securely interact with Contis APIs?

    Security keys enable you to encrypt and decrypt information sent to you via an API request. You must also connect to Contis using a secure VPN.

    Are security keys same for all the Contis Environments?

    No. Each Contis environment has its own set of security keys.

    How are the security keys shared with you?

    During the initial setup, the keys are shared via SFTP.

    How do I set up a VPN connection with Contis?

    Follow this guide to set up a secure VPN connection with Contis.

    What is VPN-DR form?

    A VPN-Disaster Recovery (VPN-DR) form records all the configuration details of your VPN setup. Your data is replicated in another secure location with an IP address, different from the Live or Production. In the event of a disaster, Contis connects your IP to that of the DR site and maintains continuity of the service. Disaster recovery only exists in the Production environment.

    What is the purpose of SFTP?

    Secure File Transfer Protocol (SFTP) is safe method of connecting to a dedicated shared drive for file sharing with Contis. Each API environment has a different SFTP, i.e. one for Sandbox and another for Production.

    How do you set up a SFTP?

    Follow this guide to set up a secure FTPguide to set up a secure FTP connection to Contis.

    What is Scheme setup from an API perspective?

    A Scheme is an arrangement or build of the API product as per the agreement between you and Contis. A scheme consists of card designs, terms and conditions, and other settings.

    What are the security keys?

    The keys that control information flow between your application and Contis. They encrypt and decrypt the information exchanged between your URL and Contis. There are two major categories of security keys – for the physical and virtual cards.

    What is the API set up process?

    Briefly, the API set up process is:

    1. Scheme set up
    2. SFTP set up
    3. VPN set up
    4. IP whitelisting
    5. API account configuration
    6. Testing

    What is an API request?

    An API request is the method for calling a function held on an API server. The request will contain all the parameters you wish to pass into the function.

    What is an API response?

    An API response is data sent back by a server in response to a call or request you made.

    What are different types of responses?

    Error and success.

    What is success response?

    A response from Contis that confirms that your request was successfully handled. In other words, you API call was successful.

    What is Error response?

    A response from Contis that indicates that something went wrong. An error may be caused by unauthorized access, using wrong parameters in a call and more. The error response helps you to understand what went wrong during the call.

    What is IP white listing?

    Your official URL is added in the Contis database. This is process is known as IP white listing. This enables a secure VPN connection to be made between your URL and Contis. If you call from a different IP address that is not white listed, your call is rejected.

    Can I access all the APIs?

    Access to the APIs is rights-controlled, that means you can only access those APIs that you have registered for during your account set up.

    What is a Standing order?

    A Standing Order (SO) is an instruction to transfer a fixed amount on a daily, weekly, monthly to a beneficiary account. The instruction can be set to make a fixed number of payments at specified time intervals.

    What is an error code?

    The numbered code related to the reason of failure of a specific API call method.

    What are Contis API best practices?

    Contis recommends the following best practices to reduce system overload and optimise performance:

    • When you log in to Contis, the platform returns an authentication token. The token persists for 2 hours after the last API request or response. You can save time by calling the sign in method once and reuse the token for subsequent requests.
    • Use standard formats for date, time, Boolean and in any ISO fields exchanged during AP calls – formats can be found in the API reference.
    • Store parameters such as ‘CardProgramDesignRef’, ‘ControlAccount’, ‘MasterAgreementCode’, ClientCode, etc, globally in your web service client.
    • Store log-in parameters such as ‘APIusername’, ‘APIpassword’, ‘HashPANKey’, ‘3DESPINKey’, ‘SecretKey’, ‘FTPUsername’, and ‘FTPPassword’ as global parameters in your system to enable quick change whenever needed.
    • Understand response codes to avoid repeated call failures and to provide useful error messages to your users.
    • Understand all the look-up values before making an API request.

    What are Envelopes?

    Envelope enables your customers to set aside funds on payday for their recurring weekly or monthly expenses. The Envelope safeguards the funds needed for essential expenses, preventing accidental overspend and automatically pays pre-arranged amounts for important expenses like rent, utilities, and grocery bills.

    Your customers have peace of mind that funds in their account sitting outside the Envelope are disposable.

    Can I access my Envelopes through API?

    Yes. Within the Envelope Controller you can use API methods that enable you to execute different Envelope-related functions:

    • Reserve funds in an Envelope within an account or release back the fund into account from envelope.
    • Execute Direct Debit payments through an expense envelope.
    • Get or update information about an envelope.
    • Fetch a list of envelopes within an account.

    What is HOSC?

    HOSC stands for Home Office Sanction Check. The Home Office Sanction database stores the names of persons blacklisted by the Home Office Treasury for their involvement in financial crimes, frauds and nefarious activities. Contis downloads the updated file from Home office site on a regular basis.

    Your client's name is screened against the database. If the name matches, it is kept in the suspected list and marked as "pending". Once a name is verified, it is either given a new status - "Match" or "No Match”. If the status of the application is " Match", the application is rejected.

    How does Contis execute the KYC process?

    Contis crosschecks a consumer's or consumer’s identity against an identity database. Based on the verification, a score is given and if it falls within the pass range, then the account is created.

    KYC
    Status

    Description

    Pending 

    The status of the new application for which KYC is underway or not yet complete

    Pass

    The status of the new account application, whose KYC score is within the defined acceptable range

    Restricted

    The status of new application, whose KYC score or value cannot be configured as it is only read only

    Refer

    The status of new application that fails to reach a score value within the defined range of Pass and Restricted

    Alert

    The status of the new application that fails to get all above mentioned status. This KYC status is manually generated by the staff member and has the authority to assign "Alert" status to the new user.

    When a new consumer is added, a KYC check is made automatically. KYC is followed by a Home Office Sanction Check (HOSC), which is a criminal background check. These checks can take up to 20 minutes, so the API will not immediately return a response.

    What is Token?

    The authentication key generated after successful login to the Contis API system. The token is used when to authenticate the user every time a call is made to the Contis server.

    What is a Device Token?
