Rest Api for internal sharepoint

Question

I've been trying to connect to our internal SharePoint 2016 using postman. I've generated an ID and Secret, but I am unable to generate an access token. When using the get http://share-internal.SITENAME.com/teams/TEAM/_vti_bin/client.svc/, instead of getting an authentication error like in the other examples online, I get some difficult to understand xml and the 200 OK. Is this an issue specific to internal sharepoint?

Hi @Schwartz Timothy J ,
Since the way to access sharepoint 2016 is different from sharepoint online,take following steps:
Step 1 – Get your SharePoint site’s FormDigest using Contextinfo call

1. In Postman, the contextinfo endpoint URL for your SharePoint Site…something like: https://mySharePointSite/_api/contextinfo
2. Set the Accept header: application/json;odata=verbose
3. Set the html verb to POST
4. Hit Send

With Results:

1. Copy the big string of characters inside the <d:FormDigestValue> ~~~ </d:FormDigestValue> tags

Step 2 – Make your HTML GET Request (or POST if you’re posting)

1. Enter your endpoint URL…something like: https://mySharePointSite/_api/web/lists/getbytitle(‘MyListName’)/items?$select=Title
2. Set the Accept header: application/json;odata=verbose
3. Set the HTML verb to GET (if you’re getting data. POST or PUT or whatever if you’re doing something else)
4. Add the header X-RequestDigest and paste the FormDigestValue copied above into it
5. Hit Send, and you should be good to go
