I’m doing something similar with Zapier, and this is working quite well for me. I have a zap that:
- parses an email from my Google Apps domain
(… 1b. and strips a string from the to address as a unique id) - sends the attachment to DropBox
- Uses Zapier’s Webhook zap to post a number of pieces of the email to my app’s Bubble API to post (using the Workflow Post API). The API then stores data from the email and data from Dropbox to my Bubble app.
I’m including screenshots of my Zap and bubble API images for you to see.
Wedbhooks by Zapier, POST “Edit Template” screen actions
And headers for authenticating:
Bubble API Workflow Endpoint
Bubble API Workflow “Create New Thing”
