Zapier Newbie Needs Help Connecting WordPress to Instagram Business

I’ve progressed a little bit, but can’t get past the code-414 in the screen print attached.  Its a get to wordpress post - I don’t see how the url is too large… 

I’ve followed the two website articles here:

https://goldpenguin.org/blog/get-featured-image-from-wordpress-when-using-zapier/#:~:text=In%20the%20URL%20field%2C%20select,but%20may%20contain%20extra%20parameters.

Is this what you mean?

Hi @Troy Tessalone 

I’m not totally sure what you mean, but maybe one of these two screenshots help?

Thanks, @Troy Tessalone 

Is there anywhere that can assist me with what I’m actually asking Chat GPT to do?   As I’m not techy, I'm guessing it would be something like “create some javascript code which extracts JSON wp:attachment href to an image url” … that doesn’t make sense to me though.

Regards,

Steve

Hi @Troy Tessalone 

I was able to get something out of chatGPT but unfortunately it was unsuccessful and getting the required information as the code needs to be tweaked and I don’t have the background to do that.   

I then tried a different approach which was to create a custom field against each post using WP Code which works (see below) but then I've not been able to figure out why or how that field (or other custom fields against a post) are selected from the Wordpress trigger information.  Is there some way to get this information in the list of post contents drop down?  I tried refreshing feed, but that does’t work (note the intention was to figure out if I could then use that as the input into the Instagram feed trigger instead of the option above).

add_action('publish_post', 'add_custom_field_automatically');

function add_custom_field_automatically($post_ID) {
    // Check if the post has a thumbnail
    if (has_post_thumbnail($post_ID)) {
        // Get the thumbnail URL
        $thumbnail_url = get_the_post_thumbnail_url($post_ID);

        // Add the custom field only if the post is not a revision
        if (!wp_is_post_revision($post_ID)) {
            add_post_meta($post_ID, 'featured-image-thumbnail-url', $thumbnail_url, true);
        }
    }
}
