Need Change API endpoints from v1 to v3

[NVerma7]

Hello,

I'm currently working on updating an integration that still uses the HubSpot V1 API to V3, but I'm encountering some issues with specific endpoints.

The endpoint:

https://api.hubapi.com/contacts/v1/lists/{listId}/contacts/recent

Does this have a functional equivalent in V3, or will it continue to be supported?

Although there is an endpoint in V3:

/crm/v3/objects/contacts/{contactId}

it doesn't return all the same data as the V1 /profile endpoint. To retrieve similar information, I have to use the ?properties= query parameter — but the list of properties gets really long (I mean really), and I'm unsure if that's the proper or recommended approach.

Thanks in advance — I look forward to your response!

So to switch to v3 you will have to take a Two-Step Process: 

1. Get the List Memberships 
 - Use the v3 List API to get contact IDs from a specific list: https://api.hubapi.com/crm/v3/lists/{listId}/memberships 

After you have the list then you can: 
2. Batch read Contact Details with post request on https://api.hubapi.com/crm/v3/objects/contacts/batch/read
with needed properties, in your case maybe: 
"properties": [ "firstname", "lastname", "email", "lastmodifieddate"]

-- You then have two(three) option for the filtering: 

1 and 2 are to be used for client-side filtering after retrieving the batch results
1. Since V3 Contacts API supports and you recieveupdatedAt , you can filter contacts updated after the specified timestamp. 

2. After you include the lastmodifieddate , then you can sort the results by last modification date.
3. Third avaliable option is the search api https://api.hubapi.com/crm/v3/objects/contacts/search for more complex filtering using the lastmodifieddate . However careful with the limits. 

Hope this solves your problem. Have a good one.

Hi NVerma7,
The URL https://api.hubapi.com/properties/v3/properties/contacts  to get contact properties is wrong.  

The correct endpoint 

https://api.hubapi.com/crm/v3/properties/{objectType} 

or in your case

https://api.hubapi.com/crm/v3/properties/contacts

We are currently migrating from the deprecated V1 endpoint:

GET /contacts/v1/lists/{listId}/contacts/recent

We were using this to retrieve recently updated or added contacts from a specific list, optionally filtered by a timestamp (time-offset).

As this endpoint is no longer available in V3, we would like to understand the correct approach in V3 to achieve the same goal. Specifically:

1. How can we retrieve recent contacts from a given static or dynamic list (via list ID) using V3 APIs?

2. If not directly possible, what is the recommended workaround to fetch contacts associated with a list, filtered by last modified date or a specific timestamp (like last 1 day)?

3. Can we filter contacts using a custom property (like source_list_id) or via workflows to replicate the original behavior?

We’ve reviewed https://api.hubapi.com/crm/v3/properties/contacts, which supports date filtering vialastmodifieddate, but we couldn’t find a way to filter by list membership.

Please advise on the recommended setup or workaround to get this data accurately.
