Using "New Payment" in Wave as a trigger for Zapier
TL;DR: I want new payments in Wave to trigger a Zapier automation that records the payment in a my invoicing software (Estimate Rocket).
I'm a painting contractor and I use Estimate Rocket (ER) to generate my estimates. I also use ER to generate my invoices/work orders/change orders/receipts. It works great and I love it. I'm now trying to improve the automation in my business using Zapier.
Right now when I create an invoice in ER, it triggers Zapier to create an invoice in Wave. I'm happy with this integration. But when I receive payment, that needs to originate in Wave (because credit card payments are made through Wave). When a payment is recorded in Wave, it'd like it to also be recorded in ER. But I can't figure out how to make a new payment a trigger event in Zapier.
Please help! Thanks
