Service HTTP rules
The HTTP integration interface in the Pega Platform supports interactions between your Pega Platform applications and other systems through the HTTP protocol.
Use HTTP services rules when your applications need to process service requests that contain XML or other string data (text) without the need to comply with messaging standards or protocols like SOAP. You can also use HTTP service rules to process HTML POST data submitted to the Pega Platform from a form.
The content type of the message data sent to a HTTP service rule can be
text
or
gzip.
A low-overhead stateless alternative to SOAP, Service HTTP rules can implement services in a way that is consistent with REST (Representational State Transfer).
HTTP services generally process service requests synchronously. That is, they immediately perform their requested processing and return a configured response while the calling application waits. However, you can configure HTTP services to process service requests asynchronously, which means the service queues the request for asynchronous execution and the calling application calls back later for the results. Additionally, you can configure synchronous HTTP services to check for specific error conditions that you expect will be temporary — work item locks, for example — and then queue service requests that fail for those reasons for another attempt at a later time.
