Hello. This error log was generated yesterday. I am trying to include a form on my website that, when filled out, does two things: (1) populates the person’s email address to a specific ConstantContact distribution list, and (2) sends the response form to me by email. Currently, neither of these functions is working. When I complete the form on the newly-created page, the only thing I see is an error code that pops up briefly. It reads “API call failed. Server return status 400.” And then it re-directs to the URL I put as the next page after submission of the form.
