This is a follow-up to my previous post "Meaning of Status Code 201". Can you please provide the definitions for status codes 201, 400, 401, 403, 409, 500, and 503? Thanks!   Moderators: Assuming you work for Constant Contact, can you please contact the API programmers at Constant Contact and ask them for a list of the Status Codes and their meanings? Then, please copy & paste the codes and definitions in your reply to this post. Thanks again!    My company's app is throwing a 201 status code when attempting to send emails and I have not figured out what needs to be done to resolve this issue. The app does the following: Adds a person as a contact based on their email address. The contact must be subscribed to Constant Contact. Creates a new contact list. Adds contacts to the list. Adds the campaign. Adds the contact list to the campaign. Schedules the campaign to be sent. I found definitions of some of the error codes in Constant Contacts documents, but I have not found a definition for 201.    At my company, we have alias codes, error codes, notification codes, etc. stored in database tables with their definitions, which we can export to Excel and distribute to our business community. I am assuming that the Application Development department at Constant Contact implements similar practices.   For clarification, in my previous post, the excerpt of the C# code from the Client.cs was generated using an app called NSwag, which generates API client code in C#, by my company. It is not code from Constant Contact. ... View more
