Query account balance

2023-11-23 08:10

POST: /amsin/api/v1/business/account/inquiryBalance Signature required

Use the inquiryBalance interface to query your account balance.

For example:

Before creating a transfer request, it is the best practice for the Partner to call this interface on two different conditions:

The Partner can call this API to check the account balance after prefunding. The result indicates whether Zyla has received the prefunding deposits or not. For more details about the prefund step, refer to the related section in the Transfer funds chapter.
Before calling the createTransfer API cand create a transfer request, the Partner should call the inquiryBalance API first and ensure the account balance is sufficient.
