I've been asked to integrate a Delphi application with Salesforce. Salesforce are using a publisher/subscriber system they want us to subscribe to. I have no experience with this and am not sure where to start. Would anyone be able to give me some pointers on how to do this? Their developers asked me to look at COMETD https://developer.salesforce.com/docs/atlas.en-us.platform_events.meta/platform_events/platform_events_subscribe_cometd.htm . The process should be a simple one. They create a work order , we subscribe to an endpoint and then post pack some JSON once we are done. I think I can write back the completed work order using a POST to the given endpoint but I have no idea how to subscribe to get new work orders.
