People ask for "the price list", "the menu", "the brochure". The easiest and most reliable way to deliver a PDF or image through comment-to-DM is a link to the file on a button, not an attachment.
Why a link is better than an attachment
- Links open on every phone, every time.
- You can update the file without touching the automation.
- You can track how many people opened it (with UTM tags or your file host's stats).
- DM Flow sends text with link buttons, which is exactly what this needs.
How to host the file
Google Drive
- Upload the PDF.
- Share → General access → Anyone with the link → Viewer.
- Copy the link and paste it as the button link in your automation.
Your own website or store (best) Upload the PDF or catalogue page to your site, for example yourstore.com/pricelist. It looks more professional and is less likely to be flagged.
WhatsApp catalogue or Shopify collection For products, a collection page or WhatsApp catalogue link often works better than a PDF.

Tips
- Name the file clearly:

- Test the link from a second Instagram account before going live.
