Hi, @Rupali With a > 4-year-old post, the community may not be able to assist you without more context. You can try adding a reply to that old post and tagging users who previously replied.
To best utilize the community, a better approach is to share:
what you’ve built
what you are adding
where you are currently stuck
Typically, the community can help with questions about a specific issue or implementation. For code examples, you may need to look at the 3rd party documentation and their support communities to see how other devs have used those tools.
One additional option is to reach out to a partner and see if they can assist with or advise on a custom implantation — HubSpot Solutions Directory
