Hi, @b-carmichael -- thanks for this. We've had several people reach out about .NET examples, so I'm certainly interested in having some written. Unfortunately, we don't have any .NET programmers on staff, so it might take some time for us to develop these.

[b-carmichael]

@toomuchpete -- So I was thinking, maybe we could help each other out still. Although I am far from the best .net developer out there I do have some experience.

A big part of my struggle is having a full understanding of MailChimp and what I'm even supposed to do. For example, right now all I want to do is do a basic send (first name, last name, email address) to MailChimp. MailChimp turns it into a "subscriber". Once this is successful, I would than like to do the reverse - receive a subscriber from MailChimp and parse the data to retrieve the first name,last name, and email address.

Obvioulsy this is the most basic integration anyone could ask for. I figure once Im able to do this, I'd be able to take it to the next level (i.e. send/receive a list).

So, the questions I'm sure your asking yourself is... How can you help me?

Well, I was hoping you can provide me with pseudo code for the most basic integration. For whatever reason, I'm missing this basic understanding (I blame it on the countless hours of reading/searching documentation - what i wouldn't do for a real example - I learn better from example).

Until next time - thank you,
@b-carmichael

Hey @b-carmichael! Thanks for your patience with our documentation and offer to help out!

In terms of examples, we have a couple of things that might be helpful. The python examples in this repo show basic interaction with the API. If you haven't seen them yet, the overview and how-to article on managing subscribers are pretty good.

In terms of the most basic pseudocode for subscribing someone to a list, here's how it works:

1. Have the list_id already.
2. Make a POST request to /3.0/lists/[list_id]/ with JSON that represents a subscriber. Minimally, that's { "email_address": "[email protected]", "status": "subscribed"}

The other pieces of the puzzle: you'll need to use HTTP Basic Auth, which almost ever HTTP library supports directly. You'll also need to grab the datacenter component of the API key and put that into the request URL.

I hope that helps.

Hey @alaiacano -- I've made a note of your comment, but you're right that this is not the best place to go off on a long rant. Apologies if you're having trouble figuring out the API; we have new documentation in the works.

Until the new docs are complete, there's not a whole lot we can do to help developers who can't get their integrations working with the help of the existing docs, the playgorund, the fact that the API is RESTful, the JSON Schema files, and our support team.

If you have other feedback, our feedback form is the best place to leave it.

Hi @toomuchpete I was wondering if you have any updates on the C# example documentation. I am trying add a subscriber to a list but I'm struggling to implement it without any example code.

[b-carmichael]

Hi @toomuchpete - I am finally able to retrieve data from PIv3. Maybe I should be a little more specific I am able to retrieve members/subscribers off of a list. Being I can do that, I will assume I'll be able to do more, if I would like.

My question is, as I try to send a subscriber back I am getting a 404 (not found) error. I am using "POST" and I am sending the minimal requirements of email_address and status (to be honest I've included, both, first and last name). I am using the same endpoint that I was receiving from, https://us11.api.mailchimp.com/3.0/Lists/LISTID/Members?apikey=APIKEY, am I missing something?

I assume this is obvious, but I substituted LISTID and APIKEY so I don't share that data to the World.

Cheers

Hey @oliverslade -- no updates as yet, StackOverflow does have some folks who have gotten it working though, so you might check there.

@b-carmichael -- 404 leads me to believe that you're not hitting a valid endpoint. I've not tested any of he endpoints with upper case letters, so I'd probably try https://us11.api.mailchimp.com/3.0/lists/LISTID/members -- you'll also need to use one of the supported authentication methods (like Basic Auth) rather than passing the API key in the querystring.

[b-carmichael]

@toomuchpete:

Thank you for all of your help, apparently I copied the wrong URL.

I am/was using Basic Authentication, with the following endpoint: https://us11.api.mailchimp.com/3.0/lists/2c3120392c/members

*** UPDATE ***
I now have 2-way communication!

Again thank you for your patience and assistance!

@toomuchpete:

I have a quick question for you, I am working on a .NET wrapper, as I feel there is a great need for it. My question though, do you know where I can get a list of every available endpoint?

Obviously I need to build a wrapper that can meet everyone's need, not just my own. That being said, complete list of the available endpoints would be very helpful.

[toomuchpete]

The way we do it internally is by crawling JSON Schema files:

https://api.mailchimp.com/schema/3.0/Root.json

The links property will show not only sub-resources but also what can be done with the current resource. In each of those links targetSchema describes the resource returned from that call, the schema link describes what should be passed in (for methods without bodies, like GET, schema describes the querystring).

HI toomuchpete, so I have an update for you.

A colleague and I are are creating a C# wrapper for MailChimp API V3.0. We are making progress. Although we have a few questions.

List Members Instance property --- >
"interests": {
"type": "object",
"title": "Subscriber Interests",
"description": "The key of this object's properties is the ID of the interest in question.",
"additionalProperties": {
"type": "boolean",
"title": "Interest Value",
"example": true,
"links": null
},
"links": null
},

In C# how is interests reperesented as a property. The additionalProperties part is the key of the interest. So I am a little confused as to how to do this.

Thanks

Hi toomuchpete,

I am having issues with creating a new file using the post request. I keep getting an errror saying it cannot accept a file without an extension. I converted the file to a base64 string and filled other necessary properties. Any help or if you could point me in the right direction that would be greatly appreciated. I have been making a .NET wrapper for Mailchimp and am feeling real good about it.

[toomuchpete]

Hi @LiquidSean -- we really cannot offer support via Github issues. You'll need to reach out to our support team at apihelp at mailchimp dot com. Thank you.
