How can I get REST API access to my App Engine Studio PDI instance

Steve Jennings · ‎07-19-2022

First . . . I am brand new to Service Now and a pretty new developer.

I requested a PDI, it's running and I used a template to create a PTO application. Now I'd like to access that application using REST API calls. Does my PDI expose REST API?

Any source of help for this would be appreciated.

Hi, PDI's are accessable via API and they require the same configuration as a Production instance.

I would start by creating an oauth Client record via menu module
System Oauth > Application Registry

and then testing the token end point
/oauth_token.do

In Postman

Type = Post
Endpoint = https://<yourInstance>.service-now.com/oauth_token.do
Authorization Type = Bearer Token (drop down selection on authorization tab)

Body (x-www-form-urlencoded)
grant_type: password
client_id: <from Your Oauth Client Record>
client_secret: <from Your Oauth Client Record>
username: <the SNC account you are using for integration>
password: <SNC account password>

The developer portal has some good learning material and I would recommend that you work through it.

Hi Adrian . . . thanks! I actually got Postman to return a 200 by using Tony's suggestion.

However, when I try and access a table in my app, I get a "Requested URI does not represent any resource". But the URI I am pasting in gives a valid XML response showing my table.

Also, when I watch the video, it says use "Basic Auth" which returns the same message "Requested URI does not represent any resource".

Here's the URI I am using:

https://dev76724.service-now.com/api/now/table/x_857924_ptorequ_0_request

And when I put that into my browser, it works and returns my table data in XML.

Any thoughts?

Hi Steve,

when you say 'I try to access a table in my app' you try this with postman or browser and with which user are you doing this testing?

Thanks,

I simply needed to add ? to the end of the URI. All is working well in Postman.

Python is still a problem.

Thanks

And my python code is fixed and works . . . just needed to set a proxy.
