What's api to update CRM object?

Using below api I can create a new object instance but not sure how to update. Tried using PUT/PATCH but that doesn’t work.
POST https://api.hubapi.com/crm/v3/objects/p99688696_car?portalId=99688696

Hey @SDhamankar !

Welcome to the Community!

You will use patch. This is from the docs

PATCH/crm/v3/objects/{objectType}/{objectId}

Or, assuming that p99688696 is the object type id and car is the object a more drawn out example would be

https://api.hubapi.com/crm/v3/objects/p99688696/car?hapikey=YOUR_HUBSPOT_API_KEY​
