RESTClient object

The RESTClient object is built on top of the HTTPClient object; and it does not have as many advanced features as HTTPClient.

RESTClient is a simple API client that is suitable for making requests to RESTful Web Service APIs with simple, flat response data (such as a string or a JSON). It can load the JSON-formatted string returned from the APIs into the DataWindow object. The JSON string returned from the APIs must be in the format described in the section called “Supported JSON formats” in Application Techniques.

The RESTClient object supports compression for the downloaded data, but not for the uploaded data. If the data received from the RESTful web service is compressed, it will be automatically decompressed. Gzip and Brotli compression formats are supported. The developer can use the SetRequestHeader function to set the Accept-Encoding header to allow only the gzip or br compression format.

Note

This object cannot be referenced in the .NET Assembly component, otherwise the component will fail to be deployed.

Note

DataWindow object with the following presentation styles are unsupported: Composite, Crosstab, OLE 2.0, and RichText.

Note

This object uses your computer's proxy settings directly. It currently does not support enabling/disabling the proxy settings or configuring its own proxy.

Note

RESTClient (as well as HTTPClient, CrypterObject, CoderObject, CompressorObject, DotNetAssembly, JSONGenerator, JSONParser, JSONPackage, OAuthClient, PDF Builder objects, SMTPClient, PowerServerLabel, PowerServerResult) does not support multi-threading.
