Is there a way to get the meta_key of an field using the standard acf functions?
I know I could do a custom db query but that seems unnecessarily complex for such a simple task.
Thanks

Do you mean the Field Key?
If so you could use
get_field_object instead of the normal get_field.
For example, this will display all related information from our field:
<?php $myfieldname = get_field_object(myfieldname); ?>
<pre><?php print_r($myfieldname) ?></pre>
And this will display the Field Key from the above:
<?php echo $text[key]; ?>
We can skip all the above and do it in one line, on it’s own like this:
<?php echo get_field_object('text')[key]; ?>
Nope, I was looking for an unique key for every row of my repeater field. I had the hope that I could use the actual meta_id key from the db but I realized that this key changes with every update of the post .. so that’s not an option.
I’m now working on a custom field type that fills in an auto generated key.
Oh I see, a unique identifier. That does sound like a bespoke field type is the best bet.
