how can we get associated companie and contact with a deal if we are using https://api.hubapi.com/crm/v3/objects/deals/search
Hey, @SMehta7 
You’re likely running into a limitation of the search API.
Based on the documentation and what is listed as available options for the search API, you may need to make multiple calls and/or use multiple endpoints.
I understand why having a batch endpoint or a way to have this returned in a single call using the search endpoint, it would be helpful. And this is not currently possible as a single call.
If you have a moment, sharing an example request and body may he;p the community offer you a targeted workaround or next step.
Best,
Jaycee
