Get Taxonomy by Custom Field

What exactly do you want to retrieve?
Do you want a list of taxonomies? Use https://developer.www.ads-software.com/reference/functions/get_taxonomies/
Do you want a list of posts with that custom field? Use get_posts like you mentioned.

@joyously I need a lost of taxonomies but filtering using the Advanced Custom Field (plugin). I can do that with get_posts but I don’t want posts I just gave an example. I want to filter a taxonomy by a custom field that it is already there

Is the custom field on the post or the taxonomy?
If you are using ACF, you probably should ask in the ACF plugin support forum.

@joyously taxonomy. Again, I just sent one example of how to use a custom field for post. I need to use the same field with Taxonomy. I don’t think they are responsible for solving this issue since the code I sent you is from WordPress arguments. So if there is arguments for Taxonomy, this is what I would like to learn

There is not the same query arguments for taxonomies.
If you have added a custom field to a taxonomy using ACF, you need to ask them about how to retrieve it.

$array=array(
 'meta_key'=>,//key
 'meta_value'=>,//value
)
$terms = get_terms($array);

这个方法对个别ACF的字段类型是无法使用的 如附件

I got this solution:

$value = 'my value';
$args = array(
'hide_empty' => false, // also retrieve terms which are not used yet
'meta_query' => array(
array(
'key' => 'ACF_FIELD_NAME',
'value' =>$value,
'compare' => 'LIKE'
)
),
'taxonomy' => 'category',
);
$terms = get_terms( $args );
