    The platform is fully owned by Contis. It is PCI DSS Level 1 compliant and independent of multiple third-party providers - BIN sponsors, card issuers and payment processors.

    Our Application Programming Interfaces (APIs) are designed to offer a high level of personalisation and control over back-end services. Giving you more time to spend on building and scaling your business instead of managing servers and databases.

    Use our APIs to create and manage consumer profiles and accounts, handle payment card production (Visa debit, prepaid and virtual cards) and set up Direct Debits and Standing Orders.

    API controllers

    Contis APIs are REST based with resource-oriented URLs and use HTTP based response codes to indicate API errors. We have grouped our APIs by function into “controllers”. Each controller contains the APIs you will need to integrate into your interface to allow your end users to access the features for a different area of the Contis service.


    A consumer is anyone who holds an account or payment card. Main (primary) consumers are linked to the primary account and any additional secondary accounts which may exist. Main consumers must be over the age of 18.

    The main consumer can add secondary users, such as friends and family members to the primary account. Secondary users must be over the age of 13.

    Secondary users can be assigned their own secondary account with a separate account number, a facility which can be used to apply transaction limits separate to those of the primary account.

    Consumer controller

    Within the Consumer controller, the API methods enable you to execute consumer-related functions, including:

    • Create a new consumer account or add many secondary accounts to it.
    • Get or update personal and contact information of a consumer.
    • Fetch account information like IBAN, BIC, sort code and account number.
    • View list of primary and secondary consumers linked of an account.


    A primary account can have one or more secondary sub-accounts. A secondary account usually belongs to a friend or family member. Primary and secondary accounts are both linked to a single consumer agreement.

    Account controller

    Within the Account controller you can execute account management functions through the API methods, including:

    • Get information about an account, the latest balance and load limit.
    • Change the overdraft limit and terms of an account.
    • Give an account an easily memorable nickname.
    • Get a list of a consumer’s transactions and accounts.

    Note the following Account definitions:

    • Bank account – The external bank account linked to the consumer’s account.
    • Client scheme account – The main account of the client, which is linked to multiple secondary accounts of customers of the client. The client account and sub-accounts have the same programme agreement settings.
    • Third-party account – The beneficiary account within Contis to which you (consumer) can transfer money


    Contis allows you to issue and manage debit, prepaid, and virtual payment cards. Each card issued by Contis (the Issuer) has a status. Take a note of the different statuses of the cards:

    • Active – a card in normal, working mode.
    • Inactive – a card is in inactive mode. It has to be activated before you can use it to make a payment.
    • Expired – a card has reached its expiry date. The Issuer will reissue a new, replacement card if the card has transacted in the previous 3 months.
    • Lost – a card has been stolen or lost permanently. The Issuer blocks the card to prevent its misuse and if requested, replaces it. If no request is made the issuer will cancel the card and close the account. Only Active and Inactive cards can be marked as Lost. Cards cannot be made ‘Active’ again once marked as lost
    • Closed – a cardholder's account is terminated and must open a new account to continue using your banking services.
    • Blocked – a cardholder may request that their card is blocked, for example, if it has been misplaced. If found, the Issuer revokes the block instruction and enables the use of the card. A lost or stolen card is automatically blocked.
    • Cancelled – a cancelled card is blocked with immediate effect on receipt of the cancellation request. The Issuer stops charging the card fee and will close the account.
