This question has probably been asked somewhere else, but I guess I haven't been able to put the right search terms together to get the answer I'm looking for to pop up in the Google abyss.

I am trying to retrieve data from an external API and update an existing custom post with the data.

I have already created the custom post type with ACF and created a post. Now I want to update the fields in the custom post with data from the API.

BONUS: Additionally, this API is nested at various levels, so let's say I wanted to update field data with a value nested a couple of layers deep, how would I get to that value?

I've tried ACF's update_field and I've tried Wordpress's native wp_update_post and update_post_meta, but cannot seem to get either to work.

Here's what I have so far:

$url = "https://api.weather.gov/points/39.7456,-97.0892";
    $res = wp_remote_get($url);
    $res_body = wp_remote_retrieve_body($res);
    $json_data = json_decode($res_body, true);

    $post_id = 21;  
    update_post_meta($post_id, "field_6636a2a494dbe", $json_data["properties"]["forecast"]);

Any advice would be greatly appreciated! Thanks!

Use the ACF field name, not the field key. This works:

update_field('forecast_link', $json_data['properties']['forecast'], $post_id);

update_post_meta($post_id, 'forecast_link', $json_data['properties']['forecast']);

Use array keys to access nested data as needed.

I figured it out! For some reason, it did not like the actual ACF field key in the update_post_meta arguments, but once I switched it to the field name it worked like a charm!

update_post_meta($post_id, "forecast_link", $json_data["properties"]["forecast"]);
