How to Attach Files to Trello Cards Using Make.com

Have you ever tried to attach a file to a Trello card using Make.com and found yourself stuck? You're not alone. This is a common issue that many users face. But don't worry, we've got a solution for you.

The Problem

When trying to attach a 'physical' file (like a .pdf) to a Trello card, you might find that you can only attach a link. This link might be a temporary one from Airtable, which isn't very useful. You might also find that the files you're trying to attach are not PDFs, but rather small files of 1 to 17 bytes in size.

The Solution

The solution to this problem is actually quite simple. The Trello 'add an attachment' module is expecting binary data, but you're providing it with the file name. To fix this, you need to 'get' the data first.

Your Airtable module returns the URL of the file, not the file itself. So, you need to add an HTTP 'Get File' module first. Then, you can map the returned data into your data field in Trello.

Troubleshooting Tips

If you're still having trouble, make sure you're mapping the correct data. The 'Get File' module should return the actual file, not just its URL. If you're still getting small, non-PDF files, double-check your mapping and make sure you're using the 'Get File' module correctly.

Conclusion

Attaching files to Trello cards using Make.com can be a bit tricky, but with the right steps, it's definitely doable. Remember to 'get' your file data first using the HTTP 'Get File' module, and then map that data to your Trello card. With a bit of patience and troubleshooting, you'll be attaching files to Trello cards in no time.
