The way I’d approach this is to use an app like mailparser.io to parse the data. i.e…
- Send order data via workflow notification to mailparser (use the mailparser wizard to identify the fields you want). Can be read from any format but basic comma separated text is prob easiest.
- Have mailparser write the data to a google sheet. A new row will be added to the sheet for every new order workflow notification.
- Connect Zapier to trigger when a new row is added in Sheets.
- Modify Zapiers existing ‘Sheets to Shipstation’ Zap for your specific purpose.
Hope that helps
