I2Rest Client

i2Rest-client is a native IBM i tool for web communications via http/https requests. It was intended to extend IBM i api functionality with http client functions. And more than this, with provided by I2rest-client Oauth 2.0 flows your IBM i API could have access to any OpenApi service.

Scenaries

Depending on your needs I2rest-client can provide five request authorization scenaries:

Https request without authorization

Http/https requests of any type, JSON messages, stream file upload - everything is here. Please explore typical usecases

Basic access authentication

Same options as above, but with Basic access authentication. Some Usecases for a quik start.

OAuth2 Client Credentials flow

Should be used to authentificate your IBM i application on remote resource to work with its own data rather than a user's data. More about I2Rest Client Flow. Some usecases - here.

OAuth2 Device flow

Provided by i2Rest-client OAuth 2.0 Device flow allows your IBM i application to deal with protected user data on remote resource, while end users are not forced to share their usernames, passwords, and other private information. General flow description can be found here, typical usecases - here.

OAuth2 Access code flow using i2Rest bridge mode

Original OAuth2 Access code flow isn't possible on IBM i due to it's limited output capabilities (IBM i can't display an authorization web page). Nevertheless i2Rest-client can reproduce this authorization scenario with the same result for end user. Please look under the hood of Access code flow using i2Rest bridge mode.

Implementation

You can interract with I2rest-client with IBM i command, or by the mean of it's integration API.
