Integrating Pega applications in Pega Cloud with external systems

Integrating Pega Platform™ and Pega industry applications allows the Pega applications to interact with the applications and your external systems. In order to integrate your Pega applications running in Pega Cloud Services environments with your enterprise systems, use the following rule types:

  • Resources maintain the connection properties and other configuration data for your Pega applications integrations. They are used to configure services to accomplish work such as Pega file and email listeners, which establish connectivity and processing work rules, but also allow you to add operational meta-data controlling how and when these services get executed.
  • Services are used to expose integration points into the application, such as REST APIs.
  • Connectors enable your Pega Cloud application (acting as a client) to request information from external systems (servers).

The following resources, services, and connectors are available for integrating Pega applications running in Pega Cloud Services environments with your enterprise. As with any external system connectivity, ensure that you follow security best practices to mitigate attacks and prevent data loss. These practices include:

  • Using strong authentication for all requests
  • Ensuring correct authorization of application users
  • Securing network connections with TLS 1.2, and, as required, by utilizing a Pega Cloud VPN

Resources and services

Pega applications running in Pega Cloud Services environments support integrating with resources in your enterprise using industry-standard protocols.

Protocols or services Description Related information
SOAP

Create secure SOAP service connections to your endpoint interfaces in Pega when your Pega application running in a Pega Cloud Services environment needs to act as a web service.

Service SOAP rules

HTTP

Create secure HTTP service connections to your web interfaces in Pega when your Pega application running in a Pega Cloud Services environment needs to process:

  • HTML POST data submitted through a form
  • Requests that contain XML or other string data (text) without needing to comply with messaging standards or protocols such as SOAP
Service HTTP rules
REST

Create secure REST service connections to your endpoint interfaces in Pega when your Pega application running in a Pega Cloud Services environment needs to supports interactions with external systems through web services.

As a best practice, use REST connectors instead of HTTP connectors when possible.

Service REST rules
Email Connect to your enterprise SMTP, IMAP, and POP3 mail server using the Pega Email service to manage your email in Pega applications. Service Email rules
SAP Supports connecting a SAP system to your Pega Cloud application through the use of SOAP web service protocols. Service SAP rules
IBM MQ Supports interactions with external systems using the IBM WebSphere MQ middleware messaging standard. For details about Pega Platform support for and interoperability with IBM MQ, see Configuring enterprise messaging using IBM MQ.

Service MQ rules

Secure File Transfer (SFTP)

The Pega Cloud Services SFTP Service provides Pega Cloud Services clients with simple, secure file transfers to and from their Pega Cloud applications. The service supports file exchanges between your enterprise and your Pega applications powered by Pega Cloud Services, and uses the Pega Cloud File Storage repository for reliable and resilient storage.

Pega Cloud Services environments do not support using the SFTP connector rules in Pega Platform, because Pega Cloud Services does not support directly accessing files on the local filesystem of your environment.

Connectors

Connector Description Related information
SOAP Use SOAP connector rules when your Pega Cloud application needs to call an external web service. Creating SOAP integration
HTTP Use HTTP connector rules when you want your Pega Cloud application to send XML or string data (text) as messages to an external system without the need to comply with messaging standards or protocols such as SOAP. About Connect HTTP rules
REST

Use REST connector rules in Pega Cloud applications to consume information exposed by REST web services (typically presented as JSON or XML).

As a best practice, use REST connectors instead of HTTP connectors when possible.

About Connect REST rules
SAP

Use Connect SAP rules in your Pega Cloud application to connect to an existing SAP SOAP web service.

About Connect SAP rules
DocuSign Use this smart shape in a flow to send documents for electronic signatures by using the DocuSign service. Flow shapes
IBM MQ Use Connect MQ rules in your Pega Cloud applications to configure enterprise messaging using the IBM MQ messaging standard. For details about Pega Platform support for and interoperability with IBM MQ, see Configuring enterprise messaging using IBM MQ. About Connect MQ rules
