Call API-Trigger from automation.

Hello,

I like to call an API-Trigger during an automation to start a workflow.

I have tested the trigger with https://api.sap.com/api/SPA_Workflow_Runtime/tryout and got a positive result:

Unfortunately I am not able to call the trigger from the automation.

I tried it with the js-code-snippet from https://api.sap.com/api/SPA_Workflow_Runtime/tryout, but this just gives me the error:

var data = JSON.stringify({
  "definitionId": "eu10.hh8fmvfy8w5fn4lj.supplyon2.kundenauftragAnlegen",
  "context": {
    "kundenauftrag": ""
  }
});

var xhr = new XMLHttpRequest();
xhr.withCredentials = false;

xhr.addEventListener("readystatechange", function () {
  if (this.readyState === this.DONE) {
    console.log(this.responseText);
  }
});

//setting request method
//API endpoint for API sandbox 
xhr.open("POST", "https://spa-api-gateway-bpi-eu-prod.cfapps.eu10.hana.ondemand.com/public/workflow/rest/v1/workflow-instances");

Hello Fabrice,

Now you do not need to use Web Service and code to call SBPA process in the automation. We have introduced the new activity in automation where you can discover and directly call the process. Refer this documentation

Hope that helps,
Archana

It´s solved now:

-> Calling the process though an automation works, but it has limitations in the testing environment. Therefore you get an error message. One solution is to make a try-catch around it and test it manually. (I hope that SAP will catch up here and provide this in a future release).

-> Also check, if there are any certificates needed, as most companies require those for security reasons. Try to test it from another device, which doesn´t have this limitations.

Thanks!
