How to send event parameters for a tag through the google tag manager API - google-analytics

Question

With this query i can create a GTM event tag for Google Analytics 4. i would like to pass some event parameters aswell. I feel that im really close because the API seems to recognize the eventParameters key, it tells me that its value its invalid.
"vendorTemplate.parameter.eventParameters[0]: The value is invalid.\n",
If i change this eventParameters key to something else, the query goes through (obviously without taking into consideration my eventParameters) so i know that this code has to be close.
The documentation is really shallow so building queries with the GTM api its been very trial and error until now.
When i get this working i'll probably make a sample for automating trigger and tag creation for GA4 migrations
`
{
"name": "test2",
"type": "gaawe",
"parameter": [
{
"type": "template",
"key": "eventName",
"value": "hey"
},
{
"type": "tagReference",
"value": "LocalTag",
"key": "measurementId"
},
{
"type": "list",
"key": "eventParameters",
"list": [
{
"type": "template",
"value": "page_title",
"key": "page_title"
}
]
}
]
}
`

Answer 1

The parameters is a array
Here is the example:
{
"type": "MAP",
"map": [
{
"type": "TEMPLATE",
"key": "name",
"value": `${parameterName}`
},
{
"type": "TEMPLATE",
"key": "value",
"value": `${parameterValue}`
}
]
}
And if you want to pass a variable to the value
Just add the "{{" , "}}" as you used in GTM UI.
Like {{DataLayer-Ecommerce}}
So yes you are very close to it.
