Web API POST, create two records at once?

Hello,

I am testing Dynamics 365 CRM web API calls with Postman.

Using this URI: https://<mysite>.crm.dynamics.com/api/data/v8.2/contacts

If I POST this JSON code:

{
"firstname": "Joe",
"lastname": "Doakes"
}

The new contact record is created perfectly.

But if I try to POST an array of two records:

[
{
"firstname": "Joe",
"lastname": "Doakes"
},
{
"firstname": "John",
"lastname": "Doakes"
}
]

I get this error: "An unexpected 'StartArray' node was found when reading from the JSON reader. A 'StartObject' node was expected."

Is it not possible to post more that one record at a time? Or is my syntax faulty?

Thanks for any help on this.

Thanks Ben. I had seen that article, but wasn't sure if it was strictly for transactional integrity, or if it pertained to any form of batched inserts/updates.

Now that I know that it is the only supported method for multi-record updates, I will incorporate it into my code.

Hi Bryan,

you need to use a batch request to create multiple records of the same type in same operation.
MSDN: Execute batch operations using the Web API
