Nice, glad that worked!

Awesome! I think I get it now, this worked and I can see the response and get through it, you rock man!

Ah is it possible there are other results prior to the "totalRows"? If you call the rule by itself (without the ".totalRows"), what do you see? You might need to try to index other items like ".result.body.totalRows" or something like that. Any item you see in the response can be indexed into using that dot notation.

Great! I tried that and this seems to work, thanks Peter. However, I get the test output as

Time 3,919 ms (View Performance)

Type Null

Value

Formatted

Raw

Expression

null(Null)

So I guess this did not give me the rows, as I then tried to create the interface, and selected read only grid and selected rule from data source, but it does not return any values there.

Oh I just suggested SAMPLE as an example - you'll need to just use whatever the name of your integration was. It should also auto-complete when you type in rule! and begin to type.

Got it, not sure if I'm doing something wrong, I went to my app>'objects'>'New'>'Expression Rule'

this opened a new tab with the text editor there and I pasted rule!SAMPLE_TGSU_bigquery().totalRows

Then I did 'Test rule' and on Test output, I got an error:

Expression evaluation error at function rule!SAMPLE_TGSU_bigquery: Invalid function rule!SAMPLE_TGSU_bigquery (not available as [rule])

Do you have any insights?

Yes that's correct - once you create that expression rule, it should return the list of all the data from the integration. So then it's up to you how you want to use it - you could use a grid (see this tutorial: docs.appian.com/.../Grid_Tutorial.html) using the results of your rule.

Hello, yes what I want in the end, is to show the rows coming on the JSON response , as a table on Appian

With the code you ageve me, I guess I need to create a new expression rule , and it may look like this

rule!SAMPLE_TGSU_bigquery().totalRows

am I right?

So are you trying to create a record type with this integrationas the source? Usually the best way to do that is to use dot notation to index into the rowsList varaiable. Usually, I see this done by creating a separate expression rule and then using the expression rule to format your results. You should be able to return the total rows data like this:

rule!SAMPLE_YourIntegrationRuleName().totalRows
