Goal

When an Orchestration is run against an external REST API server, sometimes the first connection attempt to the external server fails and the whole Orchestration will end in error.

Currently, there is no setting for an Orchestrator connector to retry a connection some number of attempts at a specific time interval. Enhancement Request Enh 34509196 - NUMBER OF RETRIES AND RETRY INTERVAL FOR CONNECTOR DEFINITION IN ORCHESTRATOR ST has been opened to request a feature where the connector could be defined having a total number of attempts in case of a failure, at specific time interval

Since there is no setting available in AIS server or Orchestrator Studio to define a number of retries and a retry interval, this document will show how to have an Orchestration step which involves a connection to an External REST API server retried for a number of time at a specific retry interval.
