Our company intends to add a specific balance to the vendors registered in Zoho Books. Initially, we would like to set this balance amount as an example of $2000. We plan to accomplish this task using the Zoho Books API.

Additionally, when we scan the vendors' QR codes through our custom application, we want to store the scanning information in our own database. Each scanning operation should deduct a certain amount from the vendor's pre-established balance. For instance, we would like to deduct $0.20 from the vendor's balance for each scan.

At this point, I kindly request a detailed explanation of how to perform these operations using the Zoho Books API. I would appreciate information about the necessary steps to follow during the integration process, the API calls to be utilized, and any potential customization requirements.

Could you please provide me with a written explanation including the following details:

• The API call to add vendor balance and the procedure for executing this task.
• The API call to deduct fees associated with QR code scanning and the procedure for executing this task.
• Any required authorizations or special configurations.
• Any other important details or tips to consider during the process?
