Simple Examples of PowerShell's Invoke-RestMethod
I will show you how to get past this in 5 simple steps. Note: The examples provided are correct and working as of VMware vCenter 6. If you load the URL in your web browser you can very quickly see whether the certificate is trusted or not. Step 3 We need to specify the authentication URL, build a basic authorization header and set the data type we will be working with. The only thing that changes between the vendor examples is the URL, the rest you can see stays the same:.
Most of the time Invoke-RestMethod will suffice for authentication. However, there are some vendors where only Invoke-WebRequest returns the data needed. It performs the same action, but it changes the way PowerShell parses and presents the response.
Instead, just skip to the next step and pass the authentication Header to each API call. If you receive any errors double check the URL and credentials are correct by logging into the web interface using the data specified in the script. The acceptable methods listed in order of commonality are:. This is a brilliant guide. I was able to login and use the example on Nutanix without a single error or typo.

Sorry, your blog cannot share posts by email.In previous section we saw simple script which was using DSN less connection string i. We will also use query preview tool to test your API query. Also when you have multiple scripts using same connection to query multiple API endpoints it becomes very easy to reuse just DSN name rather than many connection string settings.
We can now generate queries using a format similar to SQL. Click Select Table and select value. This option will generate a query to retrieve all the data automatically. Next, press Preview Data: When Preview is pressed, you can visualize the data.
Display rest api information. For reading from multiple file make sure all files have same structure. However sometimes you will call POST request to read data too specially you have to supply many parameters in Body rather than URL to call your request. Instead, it gives back only a subset of data and provides a mechanism for data pagination. Below you will find a few examples of API pagination. In this example, next page is indicated by some attribute called nextlink found in response. If this attribute is missing or null then it stops fetching the next page.
The driver keeps incrementing page number and calls next URL until the last page detected error. There are few ways to indicate the last page e. By status code, By row count, By response size.
If you don't specify end detection then it will use the default i. No records found. The driver keeps incrementing page number and calls next URL until the last page is detected. Or can you? By default, when a remote server returns an error, data retrieval is stopped, an error is raised and no data is given back to you. This might not be always desirable. And, of course, you want to download it and use it daily in your Power BI report. Which consequentially means other data sources won't be updated as well and you will see old and cached data on the report.
You ask it to give you some file or data and it, like a snotty kid, just doesn't give it to you! You have to ask twice or thrice before it does its job. Just fill in a username and a password and you are good to go! For example, your API may allow you only 5 requests per second.

See the Notes section of this article. The command uses the Format-Table cmdlet to display the values of the Title and pubDate properties of each blog in a table. The Invoke-RestMethod command is run with all variables in place, specifying a path and file name for the resulting CSV output file. Instead of parsing the header to get the URL for the next page, you can have the cmdlet do this for you.
This example returns the first two pages of issues from the PowerShell GitHub repository. This example demonstrates how to update a user's profile. The profile form requires these fields: firstNamelastNameemailavatarbirthdayand hobbies. The API is expecting an image for the user profile pic to be supplied in the avatar field.
The API will also accept multiple hobbies entries to be submitted in the same form. By default, the values of the HashTable will be converted to strings. If a System.
FileInfo value is present, the file contents will be submitted.
If a collection such as arrays or lists are present, the form field will be submitted multiple times. By using Get-Item on the avatar key, the FileInfo object will be set as the value.
The result is that the image data for jdoe. By supplying a list to the hobbies key, the hobbies field will be present in the submissions once for each list item. APIs often require passed headers for authentication or validation. Allows sending of credentials and secrets over unencrypted connections.
To override this behavior at your own risk, supply the AllowUnencryptedAuthentication parameter.Welcome PowerShell User!

Most web pages that return useful data provide this information with the intention that it will only ever be displayed by a web browser. Extracting this information is always difficult, although Parse and Analyze a Web Page from the Internet usually makes the solution simpler than straight text manipulation. When a web page is designed to be consumed by other programs or scripts, it is usually called a web service or web API. Web services are the more fully featured of the two.
Connect to a Web Service demonstrates how to interact with web services from PowerShell. Because of their simplicity, they have become the dominant form of web service on the Internet. Unlike Invoke-WebRequestthough, Invoke-RestMethod assumes that the data returned from the website is designed to be consumed by a program.

I would suggest to not go through the Guided Setup process for this. First think you want to do is generate a new Application Secret Key. It will only show you the key once so note it somewhere we can reference later.
Make sure you grant your application the permissions that best fit your needs. In my example I gave it some basic permissions for the time being. You can always come back into your app and grant or remove permissions as needed.
The application is capped currently at 30 permission objects. Save the application because next we will need to make changes at the Application Manifest.
Introduction to PowerShell REST API authentication
This value is looking for an array so it must be in square brackets . Copy over the entire script below. We will go through it piece by piece.
By the end of it you will have authorized your application to connect to the GraphAPI and exported the Access Token which you can continue to use. Next, we will want to create a credential object and store it in a variable called ClientCredential.
Next, we will want to enter our Graph Application parameters. The Name is the name of the application. The Tenant is the tenant domain, this is the. Next we are going to create a new graph application using the parameters we set above.
This will be stored in a variable called GraphApp. This is required at least once to authorize the application to act on behalf of your account.
The username and password is not passed back to, or stored by PowerShell. For the final step we will get and store our graph access token. This will be used whenever we want to connect to the Graph API. When you disconnect you will want to export the AccessToken.
