Mailchimp Invalid Resource

[cpham]

I'm getting this error when trying to add a new subscriber to Mailchimp list. What am I doing wrong?

{"type":"http://developer.mailchimp.com/documentation/mailchimp/guides/error-glossary/","title":"Invalid Resource","status":400,"detail":"The resource submitted could not be validated.

Are you not supposed to post the data as a json string using a data field?

As per this documentation - Developer | MailChimp

Also the error page that it gives you tells you this same kind of things:

InvalidResource

The resource submitted could not be validated.

For field-specific details, see field_warnings or field_errors objects. This error means that the object submitted to a POST or PATCH request failed to validate against JSON schema, and could relate to campaign, interest group, merge field, or any other available object.

Also I assume you have replaced the {list_id} in the url too.

I figure it out! Thanks for your help.
