Google Analytics API V4 - Lookup by URL Query - google-analytics

Question

I am trying to use GA API to check if lead submissions are going through our system correctly.
I need to check if pageview has been logged by GA on a url like below:
*www.mysite.com/leads/?e={{email}}
The e= parameter will be a string variable (email address) I pass to my API request, so basically I am checking to see if there is a logged pageview for the passed email.
I have been looking at the GA docs and think I need to use a filter of some kind but a little unsure how to proceed.
Here is my current code, it is simply checking for all todays PageViews without any filter.
{
"reportRequests": [
{
"viewId": {{View-ID}},
"dateRanges": [
{
"startDate": "today",
"endDate": "today"
}
],
"metrics": [
{
"expression": "ga:pageviews"
}
],
"dimensions":[
{
"name":"ga:date"
}
]
}
]
}

Answer 1

To answer your question in a more general sense, you should use dimension filter clause.
Example:
{
"reportRequests": [
{
"viewId": {{View-ID}},
"dateRanges": [
{
"startDate": "today",
"endDate": "today"
}
],
"metrics": [
{
"expression": "ga:pageviews"
}
],
"dimensions":[
{
"name":"ga:date"
}
],
"dimensionFilterClauses": [
{
"filters": [
{
"dimensionName": "ga:page",
"operator": "PARTIAL",
"expressions": {{email}}
}
]
}
]
}
]
}
