Hi folks, I am looking to bulk load data using the [API](https://developers.hubspot.com/docs/api/crm/crm-custom-objects). I was able to do that for standard objects using the OAuth and now I want to extend the capabilities to custom objects. My question is that, will I be able to load data to custom objects using standard APIs, or would I need to enroll in the [Custom Objects OAuth Pilot Program](https://developers.hubspot.com/docs/api/custom-objects-schema-pilot)? The user will create the custom object on Hubspot and we just want to load data into it. PS: We are building an ETL tool and the features of loading data would work for multiple companies ---

Hi @SVaish9, By loading bulk data to a custom object, you mean to update the custom objects in bulk? If this is what you want then you can achieve it by - **/crm/v3/objects/{objectType}/batch/update** and if you want to read custom objects in bulk you can by - **/crm/v3/objects/{objectType}/batch/read** More details here, in the objects tab - [Accounts Dashboard | HubSpot](https://developers.hubspot.com/docs/api/crm/crm-custom-objects) Best Regards ---

Hi @himanshurauthan , Thanks for answering the query. What we wanna do is to pull data from our database and push it into custom objects. For this, I went through the APIs you mentioned - how do we get the **objectType** you mentioned in your answer. Also, I had a look at the [import API](https://developers.hubspot.com/docs/api/crm/imports) and it has the option of loading the data in custom objects but the problem is the **columnObjectTypeId** to load the data. How can we come to know about columnObjectTypeId in the [**import API**](https://developers.hubspot.com/docs/api/crm/imports)? In a nutshell: 1. Is there a way to list custom objects via API? 2. Can we add/update data to those custom objects? 3. Is there a need for us to enroll in the pilots’ program of custom objects if we are only looking to add/update more data in the custom objects and not create custom objects? Since we are a SaaS company, these features of loading data to custom objects would be used by multiple enterprises. ---

You can get all of the portal defined schema using this API - **/crm/v3/schemas** And yes, you can create/update the custom objects. And no, you don’t have to enroll in the pilot program, but I would recommend you to do that, to be updated with the latest features. Best Regards,
