My client uses Zoho Invoice to send out invoices to customers. I'm wondering if there's a way that when an invoice becomes overdue in Zoho Invoice that it automatically sends a webhook to an endpoint on their Web App(that i'm building for them) with various details like the customer's email for which the invoice is overdue?
That way on their Web App i can flag that customer.
Right now I see that the Invoicing API as an endpoint where I can list invoices by providing various details such as the customer's email address, and then pass it the status of "overdue" to see if there are any overdue invoices for the customer: https://www.zoho.com/invoice/api/v3/invoices/#list-invoices
But I'm wondering if I can get around having to query the Zoho Invoicing API to check if a customer has overdue...by just having Zoho Invoice send a webhook to the Web App with the customer's email so that I can save them as flagged and don't have to call the Zoho Invoicing API for that.
If this is not possible in Zoho Invoice, is it possible in Zoho Books?
