Jean Can you explain the method. we are looking something similar solution. how did you pass the data into WebAPI

Using an integration and a WebApi in Appian itself work fine but the integration should be a post with usage "Query data". By this way the integration can be called in a local variable initialization and the WebApi finally write the data. But for performance consideration, it require an authentication not really necessary.

David, it looks like my reply to you had been programmatically filtered for human review for looking like spam so it showed up in a different spot - let me know the bit about UUIDs/users was somewhat helpful. -Agustin

Dai Williams - You can call webAPI in Integration and use it in the form load which should write to DSE.

Thanks, but this is for a record not a task.

Dai Williams - You can create a process to insert the data before the form loads...

I hear you - this gave me trouble as well, and I don't know of a solution to both parts of your problem (1 - who, 2 - which record).
I want to give an update that when I was trying to do this, I was trying to track the user as well and I later found the logs, as Stewart commented. Since I was using Sites, I was able to do what I needed to with /audit/sites_usage.csv .

For the user (the "who" part of the question), you will see the user UUID in the log Stewart mentioned, which looks like: _h-0000aa15-eaaa-9000-9aa-010a02084a_3
I got a list of all usernames, then used the user function on those to build a mapping table between usernames and UUIDs like user(X, "UUID").
You can also search by UUID under "/suite/design" - USERS - Search box.

Hi Stewart, so the Use Case is exactly the same apart from the key question - WHO accessed the record. I have reviewed the log files and while it tells you what record has been accessed, I dont think it tells you what instance of the record and who accessed it.

I'd be more interested in what the actual use case is. At my current client they want an audit log entry written each time someone navigates to a Record Summary and/or any other Record related View. The instinct is to try and achieve what's described above but in actual fact Appian does write to an audit log these events (look in system logs/audit/records_usage.csv). This contains all the relevant details for these events and it then becomes a matter of extracting those events and dispatching/storing them as required.

Has anyone come up with a solution for writing to a database on a UI load without any external development, so purely within Appian?

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!
Agustin

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.

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.

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,

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