Usage in Element API endpoint?

[sonoflee]

I'm trying to work up a json feed of events with Element API, and having trouble figuring out how to get calendar occurrences for each event. Would appreciate guidance if anyone else has had success with this

Anything you can do in twig you can do with php inside an element transformer.

Not tested but something like this could work. I am using the example snippet from the Element API docs.

<?php

use craft\elements\Entry;
use craft\helpers\UrlHelper;

return [
    'endpoints' => [
        'events.json' => function() {
            return [
                'elementType' => Entry::class,
                'criteria' => ['section' => 'news'],
                'transformer' => function(Entry $entry) {
                    // get the next 10 occurrences
                    $eventDates = $entry->yourCalendarizeHandle->getOccurrences(10);
                    // or get recurring events between dates
                    $eventDates = $entry->yourCalendarizeHandle->getOccurrencesBetween('2021-10-01', '2021-10-30');

                    return [
                        'title' => $entry->title,
                        'url' => $entry->url,
                        'jsonUrl' => UrlHelper::url("news/{$entry->id}.json"),
                        'summary' => $entry->summary,
                        'occurrences' => array_map(function ($occurrence) {
                            return $occurrence->next->format('Y-m-d');
                        }, $eventDates)
                    ];
                },
            ];
        },
    ]
];
