Authorize access to an OAuth endpoint using auth code flow

task brazil Updated Sep 10, 2026 1 min read t_AuthorizeAccessEndpiont.md

End users who own a protected resource on the ServiceNow instance must authorize access to the resource before the instance can provide the access token.

Before you begin

Role required: none. You must already be logged in to the instance that holds the protected resource. Alternatively, you can log in using the authentication method (such as multi-factor authentication or SAML) that your ServiceNow administrator already set up.

Procedure

Click the link or button on the client application where you are requesting access to the protected resource on the instance.

This kicks off the token request. If you are making a REST call from one instance to another, this link is Get OAuth Token on the REST Message form.
If you are not logged in, log in now.

If you are not the same user as the user specified in the upper-right corner, click Not You? and log in.
Click account permissions to open the list of access tokens that you have already issued.

This is the same as the Self-Service > My connected apps token list.
Click Allow to allow access and have the instance issue the authorization code (if using auth code flow) or the access token (if using implicit grant type).

If you click Deny, the authorization is not allowed, but you are not logged out of the instance.

A message that confirms access should appear. If you are requesting access from the REST Message form on an instance, the following message appears at the top of the form: OAuth Refresh token is available and will expire at {date}.

# Authorize access to an OAuth endpoint using auth code flow

End users who own a protected resource on the ServiceNow instance must authorize access to the resource before the instance can provide the access token.

## Before you begin

Role required: none. You must already be logged in to the instance that holds the protected resource. Alternatively, you can log in using the authentication method \(such as multi-factor authentication or SAML\) that your ServiceNow administrator already set up.

## Procedure

1. Click the link or button on the client application where you are requesting access to the protected resource on the instance.

This kicks off the token request. If you are making a REST call from one instance to another, this link is **Get OAuth Token** on the REST Message form.

2. If you are not logged in, log in now.

If you are not the same user as the user specified in the upper-right corner, click **Not You?** and log in.

3. Click account permissions to open the list of access tokens that you have already issued.

This is the same as the **Self-Service** &gt; **My connected** apps token list.

4. Click **Allow** to allow access and have the instance issue the authorization code \(if using auth code flow\) or the access token \(if using implicit grant type\).

If you click **Deny**, the authorization is not allowed, but you are not logged out of the instance.

A message that confirms access should appear. If you are requesting access from the REST Message form on an instance, the following message appears at the top of the form: OAuth Refresh token is available and will expire at \{date\}.
