How to send data from Unity to Mailchimp

Question

I have followed the WWWForm script reference to try to connect Unity with Mailchimp. According with the log, the form is sent without errors. Unfortunately Mailchimp did not stored any data.

This is my code:

public class EmailSendButton : MonoBehaviour {

    public GameObject emailInputText;
    private WWWForm form;

    /// <summary>
    /// In the Inspector we tell Unity to call this function when the button is clicked.
    /// </summary>
    public void onClick() {
        StartCoroutine(SendToMailChimp());
    }

    // TODO It seems to be working but Mailchimp did not store anything
    private IEnumerator SendToMailChimp() {
        form = new WWWForm();
        string email = emailInputText.GetComponent<UnityEngine.UI.Text>().text;
        form.AddField("mce-EMAIL", email); // I have also tried with: form.AddField("email", email);
        WWW w = new WWW("http://bustogames.us11.list-manage.com/subscribe/post?u=8855252b454d05c2f913c1d2b&amp;id=2ac022b22a", form);
        yield return w;

        if (!string.IsNullOrEmpty(w.error)) { print("Error sending the form: " + w.error); }
        else { print("Form sent without errors"); }
    }
}

This is the cut and paste code provided by Mailchimp:

<!-- Begin MailChimp Signup Form -->
<link href="//cdn-images.mailchimp.com/embedcode/slim-081711.css" rel="stylesheet" type="text/css">
<style type="text/css">
    #mc_embed_signup{background:#fff; clear:left; font:14px Helvetica,Arial,sans-serif; }
    /* Add your own MailChimp form style overrides in your site stylesheet or in this style block.
       We recommend moving this block and the preceding CSS link to the HEAD of your HTML file. */
</style>

    <div id="mc_embed_signup_scroll">
    <label for="mce-EMAIL">Subscribe to our mailing list</label>
    <input type="email" value="" name="EMAIL" class="email" id="mce-EMAIL" placeholder="email address" required>
    <!-- real people should not fill this in and expect good things - do not remove this or risk form bot signups-->
    <div style="position: absolute; left: -5000px;"><input type="text" name="b_8855252b454d05c2f913c1d2b_2ac022b22a" tabindex="-1" value=""></div>
    <div class="clear"><input type="submit" value="Subscribe" name="subscribe" id="mc-embedded-subscribe" class="button"></div>
    </div>
</form>
</div>

<!--End mc_embed_signup-->

Answer 1

I believe it is not the input id, but its name that is used as field name when a form is submitted. So I would use:

form.AddField("EMAIL", email);

Also, there seems to be a hidden input on the form provided by Mailchimp called b_8855252b454d05c2f913c1d2b_2ac022b22a, so you should also have the following line in your code:

form.AddField("b_8855252b454d05c2f913c1d2b_2ac022b22a", "");

And lastly, if the above is not sufficient, the form might require the submit button to be there, so you could also add the following:

form.AddField("subscribe", "Subscribe");

I hope this helps.
