Bank Connection IDs and Account Connection IDs are unique identifiers within Sikoia's Banking Solution. This solution enables you to access account details, balances, and transaction data for accounts linked through open banking connections or by uploading a supported bank statement documents.

While related, Bank Connection IDs and Account Connection IDs have distinct roles, as explained below.

Bank Connection Identifier

A bank_connection_id serves as a unique identifier for a connection to a bank data source, whether it's an open banking connection or an uploaded document containing bank statements.

Account Connection Identifier

An account_connection_id serves as a unique identifier for a specific bank account or bank statement within a document.

Why might a single Open Banking connection yield multiple Account Connection IDs?

A single open banking connection (with a unique bank_connection_id) can be used to connect one or more bank accounts. Each connected account is given its own account_connection_id.

For example, if a person has a checking account, a savings account, and a joint account with the same financial institution and all of these accounts are connected through a single open banking connection, then they will share the same bank_connection_id but possess distinct account_connection_id values.

Why might a single bank statement file yield multiple Account Connection IDs?

A single bank statement file (with a unique bank_connection_id) may include one or more accounts and/ or bank statements. Each individual account or statement within the file will be give its own account_connection_id.

For example, a single bank statement document may encompass statements for both a checking account and a savings account. If provided in the same file, they share the same bank_connection_id but possess distinct account_connection_id values.

Similarly, a single bank statement document may include statements for different months. If provided in the same file, they share the same bank_connection_id but possess distinct account_connection_id values.
