Make Kintone REST API Requests with Postman using OAuth



This article introduces how to use Postman (External link) to send API requests to Kintone using OAuth 2.0 (External link) .


Postman (External link) is a collaboration platform for API development. Users can call RESTful APIs and create various tests and environments. Download the app from the Download Postman app (External link) web page.

Benefits of the OAuth Client Method

Using the password authentication method

With the password authentication method, Kintone login credentials must be shared with the linked service. This method effectively grants the linked service all privileges held by the user. The password authentication method does not allow for granting specific privileges per service. Also, the linked service's access to Kintone is affected every time the user changes their login credentials.

Using the OAuth client method

With the OAuth Client method, the OAuth 2.0 protocol is used to grant specific privileges to the linked service. This method allows for linked services to have specified access to Kintone without sharing the user's login credentials. Maintaining the integration will be simpler since the linked service's access to Kintone will not be affected by the user changing their login credentials.

Grant Type Authorization Code Authorization Code
Auth URL The URL of the OAuth authorization endpoint https://{subdomain}
Access Token URL The URL of the OAuth token endpoint URL https://{subdomain}
Client ID The unique ID created when the Postman app was registered to Kintone L.1.1a2b3c4d5f68i9k1l2m3n4o5p6s
Client Secret The client Secret created when the Postman app was registered to Kintone 123456789012345678901234567890asdfghjklasdfghjklasdfghjklasdfghj
Scope The scope determines the level of access to grant to the Postman app. k:app_record:read
State A random value in order to prevent CSRF(Cross-site request forgery) state1

After entering the information above, click the Request Token button.

Allow Postman to access Kintone

A Kintone authentication page appears when the Request Token button is clicked. Log in to Kintone and approve the authorization request.

This Access Token is set as the Token in the Authorization settings.
