Using tRESTClient and tExtractJSONFields to Access API Data

August 25, 2026 · Matt Irvin

Pull JSON from a REST API in Talend Studio and turn it into rows: tRESTClient, tExtractJSONFields with JSONPath, and a keyless public API you can run today. Rewritten for 2026 (the original used the defunct Mashape marketplace).

Calling OAuth 2.0 APIs from Talend

August 25, 2026 · Matt Irvin

Most APIs now require OAuth 2.0 bearer tokens. A complete Talend pattern: fetch a token with the client-credentials flow, extract it with tExtractJSONFields, call the authorized endpoint, page through results, and handle rate limits. Replaces our 2014 tREST/Mashape tutorial.
