v3 APIs under development

[Iffbld01]

Hi,

We want to use HubSpot APIs and we are currently in the process of analysing them. When I went through this link - https://developers.hubspot.com/docs/api/overview I found that there are quite a few APIs in v3 that are still under development or in beta. I would like to know - 

1. By when will all the v3 APIs be available?

2. Once v3 is released, is there a plan to deprecate v1 and v2 APIs?

We want to decide if it is okay for us to use v3 for some set of APIs, and use v2 or v1 whichever is present in case v3 is not available.

Thanks.

Hey, @Iffbld01 👋 Thanks for reaching out. Great questions! 

• Q1 – there is not a document with listed expected release dates
• Q2 – this will depend on the new endpoint or endpoints and what they can do. Some-but-not-all of the Legacy endpoints exist to maintain a functionality that a new endpoint cannot match. 
• Legacy endpoints are stable and supported unless explicitly flagged for depreciation
• For both questions, the source of truth for new rollouts, updates, depreciations, and breaking changes is the HubSpot Developer Changelog. You can also find a copy of those announcements here — Developer Announcements. Both of which you can subscribe to depending on your preferences. 

Have fun building! — Jaycee
