Below Open API specification will remain same in future

[https://api.hubspot.com/api-catalog-public/v1/apis/crm/v4/objects/](https://api.hubspot.com/api-catalog-public/v1/apis/crm/v4/objects/)

e.g only version will change in future from v4 to v5 ? or will entire url get change?

Can you please confirm ?

Hi @ShubhangiPawar, seeing that v3 is still up and running, I think it is safe enough to assume they will create a new URL for v5. I hope that I understood your question.

Hi RBThomas,

Thank you for reply.

[https://api.hubspot.com/api-catalog-public/v1/apis/crm/v3/objects/](https://api.hubspot.com/api-catalog-public/v1/apis/crm/v3/objects/)

[https://api.hubspot.com/api-catalog-public/v1/apis/crm/v4/objects/](https://api.hubspot.com/api-catalog-public/v1/apis/crm/v4/objects/)

As u mentioned v3 and v4 url above ,i can see the difference is only version .so in future v5 link like below: [https://api.hubspot.com/api-catalog-public/v1/apis/crm/v5/objects/](https://api.hubspot.com/api-catalog-public/v1/apis/crm/v4/objects/)

Right?

Thanks,

Shubhangi

I am sure it will be in a long time unless HubSpot does something drastically different with their API.
