CALLURL

Returns the result of an http-based url request.

Syntax

CALLURL(url; method; body; header)

  • url - the url to which the request is sent - Value type: text

  • method - the http request method ("GET", "POST", "DELETE", ...) - Value type: text (optional, default: "GET")

  • body - the body data of the http request - Value type: text (optional, default: empty)

  • header - the header of the http request - Value type: text (optional, default: empty)

Remarks

  • The function returns the result of the http request as text.

  • If the url request returns any mime type other than text/…, application/javascript, application/json, application/xml, the function returns !ERROR.

Linking the CALLURL function with a database widget

It is possible to use an authentication for the CALLURL function that is stored in a REST or Essbase connection. This allows requests to be sent directly to a REST api with corresponding authentication or to the REST api of an Essbase server, for example.

The widget for which the connection is defined is stored as a reference in the connection formula.

Example 1

After clicking on the CallURL button, the url from the top cell widget is sent, and the result is assigned to the bottom cell.

In this example, a post request is sent to a url, including body and header information.

Example 2 - ChatGPT Communication

The "CALLURL" button uses the "REST api" button as a reference in the connection formula. When a request is sent with the CALLURL function, the authentication of the connection is used, in this case a bearer token (which is required by ChatGPT).
