I have used REST in the past for creating/updating single record and used Bulk API to create records in bulk too. But there seems to be new way to creating multiple records using REST. Here is the article - https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/dome_composite_sobject_tree_flat.htm

Can someone post few help articles on how to get started? I have not used curl in the past, is there way to test this using PostMaster or WorkBench?

Edit

Let me make it simple. Suppose I have below REST resource in Salesforce, how can I call it to pass multiple contact records?

@RestResource(urlMapping='/insertcontact/*')

global with sharing class Mycontacts{

@HttpPost global static List doPost(List lstcnts){ insert lstcnts; return lstcnts; }

}

You can definitely use workbench to execute these

Use the below for the request

/services/data/v34.0/composite/tree/Account

and in the body use the below JSON

{
"records" :[{
"attributes" : {"type" : "Account", "referenceId" : "ref1"},
"name" : "SampleAccount1",
"phone" : "1111111111",
"website" : "www.salesforce1.com",
"numberOfEmployees" : "100",
"industry" : "Banking"   
},{
"attributes" : {"type" : "Account", "referenceId" : "ref2"},
"name" : "SampleAccount2",
"phone" : "2222222222",
"website" : "www.salesforce2.com",
"numberOfEmployees" : "250",
"industry" : "Banking"
},{
"attributes" : {"type" : "Account", "referenceId" : "ref3"},
"name" : "SampleAccount3",
"phone" : "3333333333",
"website" : "www.salesforce3.com",
"numberOfEmployees" : "52000",
"industry" : "Banking"
},{
 "attributes" : {"type" : "Account", "referenceId" : "ref4"},
 "name" : "SampleAccount4",
 "phone" : "4444444444",
 "website" : "www.salesforce4.com",
 "numberOfEmployees" : "2500",
 "industry" : "Banking"
  }]
}

You should see the response in workbench

Alternatively you can use POSTMAN to experiment with this API .

You will need to create a connected app in salesforce and use oauth 2.0 to get access token for subsequent calls

use the below link for reference

  • Thanks Mohith for the response. If I run “cs3.salesforce.com/services/data/v39.0/composite/tree/Account” in Postman, I get below error message { "message": "MediaType of 'application/x-www-form-urlencoded' is not supported by this resource", "errorCode": "UNSUPPORTED_MEDIA_TYPE" } What should be the “Content-Type” ?

  • It was in 2013 at that time we did not have composite or tree API's

  • Making some progress. I can insert the account. Couple of follow up questions - How to differentiate between insert, update, etc - How can I call custom REST resource?

  • Try giving an Id and see what happens .I guess tree is only for inserts .

  • Tried that, it complained. I think it is only for inserts. I also tried changing to "Patch" but only Post is supported. So back to the question. What is best way to pass json/csv file using REST, preferably custom REST? Seems simple, but only way I see so far is bulk API.

As of API v42.2 you can now use the SObject Collections Composite endpoints. There are two major benefits over the existing composite tree & batch endpoints.

1: You can update up to 200 records at a time

2: The updates take place in a single execution context on salesforce. The other composite record create a context PER RECORD, which make it run incredibly slow for big updates.
