Since I started with Moneybird, I wanted to have an easy and 'free' iDeal link in my mails with invoices. I did a feature request at Moneybird to have a tag for the 'raw price' of an invoice without currency and spaces, so I can generate bunq.me links. There was a tag already, but it included the currency sign and some spaces, so it wasn't possible to create a valid url.

I wanted to share my solution, because my clients love it;

1. In MoneyBird go to settings > Workflows > Edit standard.
2. In your mail paste this piece of text to redirect people to your bunq.me page with the amount and invoice number prefilled;
   https://bunq.me/YOUR_BUNQ_ME_NAME/{document.total_price_raw}/{document.invoice_id}

I'm sure your clients will love it!
