RestExplorer

An APEX implementation of the REST Explorer in the Salesforce Workbench

Features

• Allows user to call REST API to its own org, in APEX code
• No OAuth is needed
• Resolves the session Id problem in lightning context

Examples

Get a description of all available objects in Tooling API:

String result = new RestExplorer('/tooling/sobjects').getResult();

Create a new Tooling API object:

String result = new RestExplorer('/tooling/sobjects/MetadataContainer/')
    .doPost()
    .setBody(new Map<String, Object>{'Name' => 'TestContainer'})
    .getResult();

Run a query on Tooling API:

String query = 'SELECT Id, Name From MetadataContainer WHERE Name = \'MyMeta\'';
String reusult = new RestExplorer('/tooling/query')
    .addParameter('q', query)
    .getResult();

Query all datasets in Wave API and convert the JSON result to a map:

Map<String, Object> result =
    (Map<String, Object>)new RestExplorer('/wave/datasets/').getJsonResult();

Query an Account by its Id:

new RestExplorer('/sobjects/Account/001O000001HbzFwIAJ').getResult();

Update a field in an Account record:

new RestExplorer('/sobjects/Account/001O000001HbzFwIAJ')
    .setBody(new Map<String, Object>{'Website' => 'https://example.com'})
    .doPatch()
    .getResult();

FAQ

What is the SessionIdPage?

The session Id from UserInfo.getSessionId() cannot be used in a lightning context, therefore we have to create a Visualforce Page and get the session Id from there. Reference: https://techevangel.com/2019/06/17/how-to-get-session-id-of-current-user-in-lightning-context/
