How to Get Multiple Select from Array in Notion?

How To

Hi,

I’m trying to fill out a multi select field in Notion from a piece of JSON, received from an HTTP GET request. The JSON I’m getting from the GET request, looks like this:

"items": [
{
  "resourceURI": "http://gateway.marvel.com/v1/public/characters/1009220",
  "name": "Black Cat"
},
{
  "resourceURI": "http://gateway.marvel.com/v1/public/characters/1009262",
  "name": "Spider-Man (Ben Reilly)"
}]

So I’m using an Iterator and an Array Aggregator to reduce that JSON to just the part I need, which is the name.

The output of that looks like this:

[
    {
        "array": [
            {
                "__IMTKEY__": "Black Cat"
            },
            {
                "__IMTKEY__": "Spider-Man (Ben Reilly)"
            }
        ],
        "__IMTAGGLENGTH__": 2
    }
]

In Notion, I’m mapping this to the Tags field of my DB, but I’m getting a 400 error:

The setup of the two modules.

In Notion, “Tags” is a Multi-Select field.

The operation failed with an error. [400] body failed validation. Fix one: body.properties.Tags.multi_select[0].id should be defined, instead was `undefined`. body.properties.Tags.multi_select[0].name should be a string, instead was `{"__IMTKEY__":"Black Cat"}`.

This is not a connection issue with the DB, I’m modifying a number of other properties in this same DB within this scenario.

The end result I’m looking for would look like this in Notion:

I’ve looked around the forums and found a number of similar questions, but no answers.

Thanks!

Same issue here. 400 each time

Hi @Lukas,

In your array aggregator select your Notion field in the “Target structure type” field and map your values directly in the aggregator. Then you just map your array in Notion.

Hi @loic.wiseflow,

Thanks for your reply! I’m not seeing any options in that dropdown. Here’s my full structure, in case you’re curious:

Hi @Lukas,

It looks like the module is not functioning correctly. I tried everything and I could not find something that output the right thing.

I was able to get it to work with an API call:

  • url: /v1/pages

  • method: POST

  • body:
    the call below populates the “Name” field and the “tags” field.

{
“parent”: {
“database_id”: “a70576f4a8074887859111a9fb212cd6”
},
“properties”: {
“Name”: {
“title”: [
{
“text”: {
“content”: “test API call”
}
}
]
},
“Tags”: {
“multi_select”: [
{“name”: “test1”},
{“name”: “test2”}

        ]
    }
}

}

Thank you! This didn’t quite solve it, since I was updating pages rather than creating new ones, but it put me on the right track. I wound up having to do a Patch request, with the URL:

/v1/pages/PAGE-ID

and the Body:

{
    "properties": {
        "Tags": {
            "multi_select": TEXT
        }
    }
}

Where TEXT was the result of a Replace module pulling the results of the array aggregator and replacing every instance of __IMTKEY__ with name.

Ah yeah sorry it was just easier for me to go POST. Good job taking this across the finish line. You should submit a ticket so Make can fix that module. It is way harder than it should be
