Authenticate twice for Web API and Organization URL - Using REST ?

(0) ShareShare
ReportReport
Posted on by Sreelatha S 5

I'm trying to read customer data from any user who has dynamics CRM account.

First step, I'm using the below url to get the access token for retrieving the organization url for the user. It shows the consent and asks for credentials. Response will have the organization url.

login.microsoftonline.com/.../authorize`+
Second step, to retrieve the data, it is advised to use the organization url and authorize as below.
`login.microsoftonline.com/.../authorize`+
`?resource=`+<organization from first step> 
It would give the access token needed to retrieve the data.
My question is, it is prompting for user authentication twice, in both steps. Is it possible to let the second step use the same credentials as the first one. 
Thanks for your help in advance,
Sreelatha

    Hi,

    Yes it is possible to interact with CRM web api using access token which you have obtained from first step without user interaction and they will not have to enter their credentials again.

    Pass Access Token in header as Bearer.

    var myHeaders = new Headers();
myHeaders.append("Accept", "application/json");
myHeaders.append("Content-Type", "application/json; charset=utf-8");
myHeaders.append("Prefer", "odata.maxpagesize=2");
myHeaders.append("Prefer", "odata.include-annotations=\"*\"");
myHeaders.append("Authorization", "Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCI6IllNRUxIVDBndmIwbXhvU0RvWWZvbWpxZmpZVSIsImtpZCI6IllNRUxIVDBndmIwbXhvU0RvWWZvbWpxZmpZVSJ9.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.S4Ao6bX9WkdIUMNcLNFyCxq3hF1jx8J_4gS4izO9jOpPzFuynyq8j3pPeqBc_6Dh-IzLu5OFIH2agol6rmZ1rlLEDi5zXQKwYvTKkKUgQZQlRLzWaIIYtQIYOReYwj6NEjfOQb6tufqGYdAVsIlJVcVqWHkfrSbsyQdoUZBObE3t-9vGUVYM-p0mFUEUYoiNzr-wKLtXrsc14Zt5aclvQmnQrt-4JVZnjOt5mSGj7PWZl5gdhLkXPYoRQhcBsMC777aqVr3o5EaZTmUJh482eQjDOMj8pGq3wipQPOZ1UKOkc6QBHqI78rObmzT-mrRP73yqNcdIe9H8jNdPgPGnyQ");
