Rest API: How to get all feeds, notes calls for a Case?

Question

Using the Rest API I am able to get a case:

https://XXXX.my.salesforce.com/services/data/v56.0/sobjects/Case/500XXXXXXXXX

I need to also get all related Calls, Notes, Emails for this Case.

Can I get that in one REST request if I know the Case?

Answer 1

You could use a SOQL query in the API to request for all the info related to case like below

/services/data/v56.0/query/?q=Select+Id,+(Select+Id+from+CombinedAttachments),+(Select+Id+from+Tasks),+(Select+Id+from+Emails)+from+case+where+Id='5004S000004Sdx5QAC'

Or there are other alternatives like using Composite GraphAPI or using GraphQL.
