What does the data field mean in an Elrond transaction?

Question

If I call the transaction endpoint from the API gateway:

https://testnet-gateway.elrond.com/transaction/89a15e2ea521764d21ac2de83064dd7c1848f83dff4dcbad0518fdf41a70d889

I get the following data:

"data":"RVNEVE5GVFRyYW5zZmVyQDRkNDU1ODQ2NDE1MjRkMmQ2MjM5MzM2NTM2MzBAMDEyMzRmQDA1OWUxZDQ2YTljM2I4OWNhMkAwMDAwMDAwMDAwMDAwMDAwMDUwMDRmNzllYzQ0YmIxMzM3MmI1YWM5ZDk5NmQ3NDkxMjBmNDc2NDI3NjI3Y2ViQDYzNmY2ZDcwNmY3NTZlNjQ1MjY1Nzc2MTcyNjQ3Mw=="

What does it represent?

Answer 1

That "data" field is encoded in base64 and it represents the Input Data field available in explorer:

It can be decoded using an online base64 decoder.
