The operations returned also favour custom user-defined routes, when none exists it will fallback to use the pre-defined routes. Just like the Open API Support the list of operations returned respects the Restriction Attributes and only shows the operations each user is allowed to see. Once imported it will populate a list of available operations that can be selected and easily called from within the Postman UI. This will open up the import dialog, where you can paste the metadata url and click Import: Once enabled, a link with appear in your metadata page:īy default the link to the Postman JSON metadata collection is at /postman, this url can be imported into postman by clicking on import collections: You’ll need to refresh this token and get a new one every hour as they expire on an hourly basis.As Postman makes cross-site requests, is also requires CORS support. Now, you should be able to work with the Dynamics API in Postman making requests in the same tab you’ve got a current token available for. Those will be the credentials cached if you have recently done this in Postman using other creds to the ones you wish to use to create this access token.įollowing this you should see a dialogue to say authentication was successful, then you will get a token appear. This will have you sign in using Azure Active Directory. If you’ve previously done this using different credentials to the ones you want to use to create this token select Clear cookies to clear the credentials Postman currently has cached. It’s key to note the client ID we’re using here is of an application registered by Microsoft for all Dataverse environments so that we don’t have to create ones in our own tenants.įollowing that select Get New Access Token. Here we are referencing the variables we created in this environment a moment ago. Give your token a name of your choice to start with, then copy the following values for the rest of the corresponding fields. Now scroll down to the point where it says ‘Configure new token’. Then choose to add authorization data to the request headers when making a call to the API. Select the authorization type as OAuth 2.0 Select the authorization tab and we will get to work configuring a token. Now select the plus next to your environment tab which will open a screen to allow you to start creating requests against the API. Now we need to create an access token to be able to authenticate using OAuth 2.0 Now, select your newly created environment in Postman with the environment switcher near the top right hand corner of the application. Once you’ve got your variables added, select save in postman to create your new environment. Set up a Postman environment (Microsoft Dataverse for Apps) – Power Apps | Microsoft Learn You can refer to the learn page here for the latest values in case they’ve been updated…

With updates to the Web API for dynamics 365 these values may change slightly. Then you want to do the same thing creating further variables using the following names and values. Now back in postman you’ll want to create a new variable called url, then paste the endpoint url as the initial value. Your endpoint will follow a structure like this…

Once you’re in your environment at select the settings icon in the top right hand corner of your screen and then select developer resources.Ĭopy the base URL under Web API endpoint. We’ll get the base url of the Web API endpoint from the developer resources in our environment. Head to and navigate to the environment you want to make a connection with. Now we need to grab some details from our Power Platform environment. Then select the plus just below the workspace name to create an environment. Once you’re signed into the Postman desktop application, head to your workspace, or a workspace you’d like to use for working with Dataverse in, then in the left hand pane, select Environments. You can get the desktop application for Postman here – Download Postman | Get Started for Free Environment connection So first, you’ll want to make sure you’ve got a Postman account and you’ve downloaded and installed the desktop application to work with. In this post, we will configure a Postman environment ready for working with one of our Dataverse environments. Using tools like Postman are a great way to discover capabilities of an API such at the Dataverse Web API. In this blog post, we’re going to take a look at a tool we can utilise to make working with the Dataverse Web API loads easier! Similar to Graph Explorer, but for a number of API’s, Postman is a tool that lets you authenticate to your Microsoft Dataverse environments, then providing the ability to create and send requests to the endpoint, which return the responses within the Postman UI.
