ElasticSearch query to exclude certain results

Asked 2021-Jun-08 at 07:10

You can do it with the $event parameter. Make sure to compare your values safely.

If your value is not in the right type or has spaces or unwanted chars, this c.state == val might not work.

You can use the trim function to compare your value safely: c.state.trim() == val.trim()

I really suggest you don't do query like that. for example, you could select all names in one single WHERE condition. And be ready to use JOIN if you have several tables need to be connected.

Using Javascript Code in Zapier to return Two Letter ISO Country Code

Asked 2021-Jan-14 at 05:47

I have a functioning Zapier Email parser that provides a country name that I need to submit into Salesforce as a Two Letter Country Code as part of a lead.

From what I am reading, this should be possible using the Code function of Zapier, and Javascript.

I found a javascript code that appears to work in other situations, but I am not familiar with Javascript to be able to troubleshoot this further.

When I run this using the input of "name" as the parsed country, it gives an error of SyntaxError: Unexpected template string
