# Source IBAN Validation

We have added several new APIs to manage and store IBAN linking requests for SME users and accounts. These APIs ensure that IBANs are securely associated with accounts and can be used for validation purposes. 

Below you can find the list of relevant APIs:

* [Link source IBAN with SME user/account](https://portal.stg.platform.ae-1.nymcard.com/default/documentation/02_api_specs#tag/Accounts/paths/~1v1~1accounts~1iban~1bulk~1link/post) - users can use this API to link source IBAN with SME (nCore) user\_id / account\_id and IBAN will be parked for admin approval.
* [Update source IBAN linking with SME user/account](https://portal.stg.platform.ae-1.nymcard.com/default/documentation/02_api_specs#tag/Accounts/operation/updateLinkedIban) - this API is used to update source IBAN linking with SME (nCore) user\_id / account\_id for validation.
* [Delete source IBAN linking with SME user/account](https://portal.stg.platform.ae-1.nymcard.com/default/documentation/02_api_specs#tag/Accounts/operation/deleteLinkedIban) - this API is used to delete source IBAN linking with SME (nCore) user\_id / account\_id for validation.
* [Get linked source IBAN with SME user/account](https://portal.stg.platform.ae-1.nymcard.com/default/documentation/02_api_specs#tag/Accounts/operation/getLinkedAccountPerIbanOrAccountNumber) - this API is used to retrieve linked source IBAN with SME (nCore) user\_id / account\_id for validation.
* [Get source IBAN of SME user/account](https://portal.stg.platform.ae-1.nymcard.com/default/documentation/02_api_specs#tag/Accounts/operation/getLinkedIbans) - this API is used to retrieve source IBAN of SME (nCore) user\_id / account\_id for validation.
* [Upload document for later IBAN link](https://portal.stg.platform.ae-1.nymcard.com/default/documentation/02_api_specs#tag/Accounts/operation/uploadDocumentForIbanLink) - this API is used to upload documents for later IBAN links.
