Trigger a ESRI Survey123 Report generation via webhook, then email pdf report to user

Hi @benvk​ ! Glad you're getting some good use out of the Survey123 webhooks with FME Server. I haven't used the Survey123 Report REST API myself, but I'd like to look into it more at some point. So, I don't have a workspace or automation to share yet. But, looking at the Esri documentation and using the general steps they lay out, I would:

1. Submit the report request using the createReport/submitJob endpoint
   1. Use the HTTPCaller with an ArcGIS Online named Web Connection in place of a token parameter
   2. Request URL: https://survey123.arcgis.com/api/featureReport/createReport/submitJob
   3. HTTP Method: POST
   4. Query String Parameters:
      1. featurelayerURL: you can get this from your survey's feature layer in AGOL
      2. queryParameters: {"where": "objectIds"=@Value(objectid)} <- assuming you have an objectid attribute in your workspace for the survey response feature you want to report on; you should from your webhook data
      3. templateItemId: after you create your template in Survey123, it should be visible in AGOL where you can get the ID for it from the template item's URL (there are likely other ways too)
      4. outputFormat: pdf
      5. f: JSON
   5. This will submit a job and return a job ID (you will need to parse it from the HTTPCaller's response body JSON)
2. Create a custom embedded transformer with a loop that recursively calls the Jobs API (jobs/<your job ID>)
   1. Again, using an HTTPCaller
   2. Keep looping until you get a status returned of esriJobSucceeded, esriJobPartialSucceeded or esriJobFailed (will need to parse jobStatus from the JSON)
   3. Download and embed the ArcGISOnlineWebhookDataGetter transformer for an example of this pattern; it is used for AGOL webhooks, which are quite different from Survey123 webhooks, but have a similar flow to these Report APIs
3. According to Esri, from there: if the jobStatus is either esriJobSucceeded or esriJobPartialSucceeded, you can then download the output files. Either a URL to the file will be present in the resultInfo property for each file, or an identifier which corresponds to the itemID of the file in ArcGIS Online.

This one is a bit tricky; hope this helps. Good luck!
