How to fill campaign template with repeatablecontent via Mailchimp Marketing API

Question

I have campaing which uses template and I need to send this campaign via Marketing API with 5 (or more) latest job offers. I trying to find the way to do it.

I've tried to use Template Language on simple example.

I've added this block to template: <h3 mc:edit="article_title">Title</h3>

And then I try to update campaign content with PHP library mailchimp/marketing:3.0.27:

$campaign = $this->mailchimp->campaigns->setContent($campaignId, [
    'template' => [
        'id' => (int) $templateId,
        'sections' => [
            'article_title' => 'Test title',
        ],
    ],
]);

This request runs successfully, but I don't see any changes in response, campaing design or test email.

What I doing wrong? Or maybe there is another way to solve my problem?

I also tried to ask Mailchimp support about this problem, but got no answer.

Answer 1

The truth is that this feature was not implemented and will not work.
