TLDR: Please explain to me like I’m a child how Web API’s work.

I use project management software called ClickUp that says you can push and pull data to it through its web API. From its [documentation](https://clickup.com/api), if you click on `Lists` on the left side, then `Get List` in the middle, there are dropdown menus that show examples of how to fetch a list in many languages (except Julia). There is also a `raw` example (whatever that means), so I assume it is possible to use Julia also. I would like to read a List from ClickUp into a Julia DataFrame, manipulate, then push back. Authentication is another hurdle I will have to handle somehow. Can someone outline the general steps I need to take with Julia to interact with a web app like ClickUp?

Using the [HTTP.jl](https://juliaweb.github.io/HTTP.jl/stable/) library you can make equivalent calls to the curl examples. Some knowledge of general HTTP verbs / requests / responses / etc would be helpful to translate.

But just as an (untested) example to get you started

```julia
# curl --include \
# --header "Authorization: "access_token"" \
# 'https://api.clickup.com/api/v2/list/{list_id}'

using HTTP
using JSON3

access_token = "...." # your api key
list_id = 1

resp = HTTP.get(
      "https://api.clickup.com/api/v2/list/$(list_id)", # url
      [
          "Authorization" => access_token # headers by pairs
      ]
)

data = JSON3.read(resp.body) # json data as a dict-like structure

```

```julia

```
