How to get data from REST API (JSON) in Power BI?

[Johajong]

I am familiar with the basics of Power BI, but I don't have knowledge about using REST API's as a data source for Power BI. I know it is possible, but I am hoping that someone is able to elaborate a bit more on this subject so I am able to find the correct methods. 

To give you first of all a little bit more background information, I am using a SaaS solution in order to register company contracts. I would like to get these contracts (and related information) in Power BI. The SaaS solution considers the registered contracts as "Assets". The REST API I would like to use to get the contract information responses in JSON and I am able to connect with the REST API by setting up an authorisation code in the admin panel of the SaaS solution. 

The REST API uses different requests and within a requests there are different parameters. See an example of a request in the screen capture below:

How can I retreive the data of all Assets of a certain template and also the specific data of the fields I would like to get in Power BI? I think I am able to get to the data using the url of the request, in this case /assetmgmt/assets/templateID/{templateID}, but how do I include the desired Asset fields?

Hello Johajong,

These are the steps I use to pull JSON using an API.  I have to do this several times, because our cloud service limits ours APIs to 2000 records.   Once created, I duplicate the query, change the SOURCE text to include an offset in 2000 increments and rename the query - inventory1to2000, inventory2001to4000, etc..  Then I append them into the first query and rename the columns, filter, etc. to the appended query.  

Select:   New Source - Blank Query and in the source window enter:

   " = Json.Document(Web.Contents("https://amshowa.leading2lean.com/api/1.0/billofmaterials/?   

           auth=xxxxxxt&site=1&limit=2000&active=True"))"  (your own API)

This yields a few fields:

    limit       2000

    data        List

    success TRUE

    offset     0

Click on List and you will get a table with List as column name and numbered rows with "Record" populated

   and an action:  "NAVIGATION: = Source[data]"

On the ribbon, click on Transform then To Table (I let it default the values)

   the action shows: "CONVERTED TO TABLE: = Table.FromList(data, Splitter.SplitByNothing(), null, null, ExtraValues.Error)"  This doesn't do much, but adds an opposing arrow icon to the column1 header. 

Click on the opposing arrows in the column header and select columns/fields you want to use.

   the action shows: "CUSTOM1: = Table.ExpandRecordColumn(#"Converted to Table", "Column1", {"site", "partnumber", "lastupdated", "description", "shortpartnumber", "obsolete", "lastupdatedby", "active", "created", "lastordered", "cost", "quantity", "id"}, {"site", "partnumber", "lastupdated", "description", "shortpartnumber", "obsolete", "lastupdatedby", "active", "created", "lastordered", "cost", "quantity", "id"})"   If I want to add or delete columns in the table, I do it in here.  

You can then filter, sort, merge, etc., just as you would any other table. 

Good luck!
