This post is the 3rd in a “mini-series” where I’m documenting how I’m working with some different APIs for custom reporting. Today’s post is about ClickUp, an app I use for managing projects. Unlike the Harvest APIs I covered in post 1 & 2, ClickUp’s API is a little more challenging to deal with as there are no indicators about number of records or number of pages in the results so you need to do something a bit different than I wrote about previously. I’ll cover this in more detail in the next post.

The previous posts in this series are:

1. Connecting to Harvest in Power Query
2. Pagination in Power Query (Part 1 - dealing with a known number of pages)

For this post, I will describe the following items:

• Getting a ClickUp Personal Token
• Authenticating with that in Power Query (Power BI or Excel)
• Using “GET” method on the Spaces endpoint from the API

Some of the concepts I will cover should be similar regardless of which endpoint(s) you wish to use (at least in the context of the ClickUp API). The API documentation is the reference to what methods are available, what fields you get back, what data types they contain and what types of query parameters are available.

Getting your Personal Token

To get started, you’ll need to get your Personal Token first. This is how to authenticate if you’re just pulling data for yourself (which is my use-case). For broader reporting and/or other uses other than “getting” data, I would recommended using OAuth2 to authenticate. Like the Harvest API post, I haven’t used OAuth2 so I have no idea how it works.

Step 1 - go the Apps section in your personal settings

Go to the Settings menu (bottom left hand side of the page) and click on Apps under your own section.

Step 2 - generate an API token

In the next screen, I already have a token and cannot remember what is here initially. My best guess is it either already was populated or there was a Generate button to initially set the value. There is only one personal token, so either way, that’s all you need to get going.

Important: remember to regenerate the token if you no longer need it OR if you have mistakenly shared the Token Value with others.

Authenticating to ClickUp in Power Query

Now that you have your Token, you’re ready to get into Power Query. Here is how I have used the information to pull in Spaces, one of the API “endpoints” in the ClickUp set of APIs. As I mentioned in my mirror post on Harvest, if you are new to APIs, think of an endpoint as a destination or target, or “what you want to get”. I pull a few separate queries from ClickUp - tasks and spaces to name a couple of things.

The method ClickUp uses for authentication involved passing the Token value in authorization header with the request. If you read the mirror post to this one re: Harvest, you will see a slight difference in the core query to handle this.

Step 1 - create some parameters (optional)

This step is optional but if you are going to need to pull data from more than one endpoint, parameters will make it a lot easier to “re-use” code instead of pasting your Token in multiple queries. Also, if you ever have to regenerate your token, it’s easier to update a parameter vs. updating multiple queries.

Here is an example of what I set up (all are Text data types). Ignore the top 4, those are from the previous posts relating to Harvest and a generic ReportYear parameter.

• ClickUpTeamID with my TeamID
• ClickUpBaseURL with the root URL (https://) “api.clickup.com/api/v2”
• ClickUpAuthHeader with my token value

NOTE: I’m only putting the word “ClickUp” in front of my parameters because my particular use-case involves combining data from Harvest and ClickUp, so I need to differentiate them.

Step 2 - open a blank query

In Power Query, click on New Source > Blank Query. Next, click on Advanced Editor on the toolbar to open the editor window. The code below can be copied and pasted in, with the following caveats:

• My parameters in the query are based on “my” parameter names, which may differ from your parameter names.
• The 3 spots where this query contains a parameter are in bold: ClickUpBaseURL, ClickUpAuthHeader, ClickUpTeamID.
• In this particular endpoint, it requires a TeamID so the RelativePath is a concatenation of things to make up the remaining elements of the URL for the space endpoint.

let
    Source = Json.Document(Web.Contents(ClickUpBaseURL,
        [RelativePath="team/" & ClickUpTeamID & "/space",
        Headers=[Authorization=ClickUpAuthHeader]]))
in
    Source

There are some subtle differences between this query and the Harvest query in my first post in the series.

• The Harvest query passed authorization as a query parameter, like any of the optional parameters you could pass with it. ClickUp requires an Authorization Header. The “Headers=” here wasn’t in the Harvest example.
• Most of the queries I use in the ClickUp API require passing a TeamID. The easiest way to find out what your TeamID is, is to look in the URL of your home page.

The code above is using a method of pulling from a data query and it’s the same methodology used in the previous post (post #1 of the series).

Code Breakdown

• Json.Document = the end result I want is to convert the results to json. The value I am passing to this is the Web.Contents result.
• Web.Contents = this wraps around the base URL, a relative path if there is one, and whatever query parameters you need to pass to that URL such as authentication headers.
• The parts in the square brackets are optional in general but necessary in my case (because I need to provide the endpoint to the URL and authentication information).
  • RelativePath = the endpoint name (in this case).
  • Query = ** in this endpoint, I have nothing to filter but this section will be in the tasks example later.
  • Headers = this is the authorization header. Similar to the Query section, the values in here need to be within square brackets.

At this stage, when you close/save this query, if this is the first time using your token, you will be prompted for authentication. The token is the authentication you need, so from the “Data Source settings” standpoint, choose Anonymous. Ignore “Web API” and any other login-based authentication as that is what the token is for.

Step 3 - review the results

If the token and team ID values are valid, you should get a result something like what’s in the screenshot below. If you read the Harvest post, you’ll notice right away there is NO detail returned here to give you a clue as to how many spaces I have. The result below will be identical whether I have zero spaces, or 1000 spaces or anything in between.

Repeat the example with a different endpoint

Let’s use that same code with a different endpoint to demonstrate that the initial results are the same. In this case, I am changing the RelativePath value to “task” instead of “space”. The task endpoint I’m using also uses the TeamID as part of the URL so it’s nearly identical to spaces.

let
    Source = Json.Document(Web.Contents(ClickUpBaseURL,
        [RelativePath="team/" & ClickUpTeamID & "/task",
        Headers=[Authorization=ClickUpAuthHeader]]))
in
    Source

The only change in the code above is the endpoint, the end of the “RelativePath” line.

NOTE: All of the calls I am making are to the “v2” set of endpoints so my “ClickUpBaseURL” has the “/v2” in its URL path. There may be cases where you need to reference older endpoints, perhaps where there is no “new” version of it. If that is the case, I would change the baseURL parameter to remove the “/v2”, and then in the RelativePath segment of your queries, add that in. For example, “v2/team/(etc.)”. The total end-to-end URL needs to be the same.

NOTE 2: the “RelativePath” already accounts for the need for a slash between the “base URL” and the “Relative Path” string. It inserts the “/” between the two pieces of text so the URL would be a “proper” endpoint URL.

The results for the “tasks” endpoint look identical to the spaces result above.

One last example: query parameters

Here is one last example of the Tasks query with some additional fine-tuning. In the example above, there is no Query= section to the code. This below has that to show where it fits with the Headers= section.

let
    Source = Json.Document(Web.Contents(ClickUpBaseURL,
        [RelativePath="team/" & ClickUpTeamID & "/task",
        Query=[include_closed="TRUE", 
               subtasks="TRUE"],
        Headers=[Authorization=ClickUpAuthHeader]]))
in
    Source

The root query is the same as earlier in this post, and a Query=[ ] section has been added before the Headers=[ ] section.

• The first parameter is to indicate I want to include closed tasks.
• The second parameter is to indicate I want to include subtasks.

How did I know what to put in there?

What parameters are possible is based on the API documentation. The ClickUp API “Get Filtered Team Tasks” documentation lists several parameters I could pass in. The default for both parameters I passed in is FALSE so if I did not include those parameters, I would get tasks that are not in a Closed status and I would get Parent tasks only.

Summary

That’s it for this post. In the next post, I will talk about pagination in the context of looping through an unknown set of pages for a query like Tasks that typically will return multiple pages of results.
