Whilst the original HTTP functions was merely designed to access information on a standard web page, we have found many of our ESL customers using the facility to interface with remote web services. The following tutorial is based on a simple example provided by the W3 Schools that we have used to learn about Web Services.

If you are unable to access this web site, please contact the ESL Help Desk.

Having identified the Web Service, the main tasks are:

•Access the list of operations supported by the web service.

•For each operation, required by your application select the appropriate message type.

•Create a routine to build the require message to send to the web-service.

•Develop an extraction statement to parse the returned message.

•Create a simple test application to prove the routine.

•Insert your routines into the Esl Application.
