Good resource for writing programmable automation in workflows?

Hi, my company just upgraded to Operations Hub Pro for programmable automation. Generically, I would really like a resource where I can look up what functions are available to me in the @hubspot/api-client npm library. In node docs, they have some examples but also just link to the generic hubspot api docs: 2026-03 API reference - HubSpot docs

The specific thing I’m trying to figure out, is how to search through a custom object and find one that matches the “name” property. I understand how I could do this for contacts, deals, or companies, but not for my “brands” custom object.

Does anybody know of a good resource for seeing all available functions for hubspotClient (shown below)? Secondarily, is there a better environment for writing code for Custom Code actions in workflows that maybe has autocompletion?

const hubspotClient = new hubspot.Client({
apiKey: process.env.HAPIKEY
});

hubspotClient.crm.customObject.search(searchParams) ← Something like this

For searching through a custom object like “brands”, you can utilize the searchApi function from the crm.objects module of the HubSpot API. This function allows you to provide a set of search parameters and retrieve custom objects that match these criteria directly, without needing to retrieve all objects and filter them afterwards.

A generic example would look something like this:

async function searchCustomObjects() {

const hubspot = require(‘@hubspot/api-client’);

const hubspotClient = new hubspot.Client({

accessToken: ‘YOUR_API_KEY

});

const objectType = “Custom_Object_Internal_Name”;

const searchParams = {

filterGroups: [{

filters: [{

value: ‘Test 1’,

propertyName: ‘Custom_Object_Property’,

operator: ‘EQ’

}]

}],

sorts: [],

properties: [‘brand_name’],

limit: 10,

after: 0

};

try {

const apiResponse = await hubspotClient.crm.objects.searchApi.doSearch(objectType, searchParams);

console.log(apiResponse.results);

} catch (e) {

console.error(e);

}

}

searchCustomObjects();
