Write a row to DB on UI load?

Hi Agustin,

Did you try this with Web API and configure it in integration and call it as a rule in the UI?

Dear Raghavendra,

Thank you for your smart suggestion! I am trying to do this - I setup a Web API that successfully writes to the DB; then I setup an integration that calls the Web API (this works too, and causes the successful write to the DB). Now, I am calling the integration as a rule from the UI as follows: load( local!test: rule!testIntegration(onSuccess: null, onError: null) , {} ) - however, this fails with a similar error about "Reaction Tree" as the one above. Do you know if I am calling it incorrectly from the UI?

Hi Agustin,

Sorry for the delayed response. If it not working then we must use the tradition SOAP based web service calling from the UI. This should defiantly work.

I hope it may help you.

You're not going to be able to call an a!httpWrite() or an integration rule that POSTs data from a load(), those have to be bound to buttons/links with bind() or called from a saveInto(). User action is required to trigger something like this.

Dear Jim and Raghavendra,

Thank you very much for your inputs! Thanks to your input, I was able to accomplish this using a workaround making use of some of the suggestions mentioned. While, as Jim mentioned, it is not possible to use POST requests without user trigger/click, I was able to find a workaround by making a GET request to a custom Google Apps Script (external web service), then using that to add the row to a DB (it acts as a POST request). I ended up writing to an external DB instead (but if I needed to write to an internal DB, I would have called the Web API from Google Apps Script to write back to Appian, as Raghavendra suggested). The code in the UI looks like this:

load(
local!temp: a!httpQuery(
url: urlwithparameters("script.google.com/.../exec",
{[parameter names here]},
{[parameter values here]})
),
{}
)

For anyone trying to accomplish this, the Google Apps Script code is quite simple; basically is using the doGet method detailed here:

developers.google.com/.../web

Thank you again, Jim and Raghavendra!
