使用Mailchimp API v3添加到兴趣组_course

<div class="post-text" itemprop="text"> <p>I&#39;m using this MailChimp api v3 wrapper <a href="https://github.com/drewm/mailchimp-api/tree/api-v3" rel="noreferrer">https://github.com/drewm/mailchimp-api/tree/api-v3</a></p> <p>Using the example I can add an email to my list but cannot add it to one of my interest groups.</p> <p>This is the example code:</p> <pre><code>$MailChimp = new MailChimp(&#39;abc123abc123abc123abc123abc123-us1&#39;); $result = $MailChimp-&gt;post(&#39;lists/b1234346/members&#39;, array( &#39;email_address&#39; =&gt; &#39;davy@example.com&#39;, &#39;status&#39; =&gt; &#39;subscribed&#39;, &#39;merge_fields&#39; =&gt; array(&#39;FNAME&#39;=&gt;&#39;Davy&#39;, &#39;LNAME&#39;=&gt;&#39;Jones&#39;), &#39;interests&#39; =&gt; array( &#39;2s3a384h&#39; =&gt; true ) )); print_r($result); </code></pre> <p>My understanding is the key in that array entry for interests is the ID of the group. I created a group in MailChimp, which has a group title and group names. I can see an id when I hover over the group title edit button, and also the group name edit button. If I hover over the <em>"0 subscribers"</em> for a group name I can see that same id and a group_id. I&#39;ve tried both values and I get this error:</p> <blockquote> <p>Array ( [type] =&gt; <a href="http://kb.mailchimp.com/api/error-docs/400-invalid-resource" rel="noreferrer">http://kb.mailchimp.com/api/error-docs/400-invalid-resource</a> [title] =&gt; Invalid Resource [status] =&gt; 400 [detail] =&gt; Invalid interest ID: &#39;39561&#39;. [instance] =&gt; 12c1ab46-a0b5-4014-8107-08cfa97a9a94 )</p> </blockquote> <p>I&#39;ve googled and still can&#39;t find the answer. Any help?</p> </div>
