Unable to make Customer Contact as primary except for the First record through API call

I tried like below,

Url :/entity/Test/20.200.001/Customer/makeContactPrimary
Method: POST

Request:
{

    "entity": {

        "CustomerID": {

            "value": "AACUSTOMER"

        }

    },

    "parameters": {

        "Contact": {                     // Tried with contactID too

            "value": "Andy Appleton"

        },
         "Primary": {

            "value": true

        }

    }

}

Hi @jinin  Have you tried by setting the Name under the Primary Contact section? instead setting Primary = true at the Contacts tab.

Yes Naveen already verified,   If we use the Primary name as the  ContactID with customer update call, It will work. But the Primary name as the Contact name is not working. 
 

Hi @jinin - were you able to find a solution? Thank you!

​@jinin, I’m trying to do the same thing you have done, select a customer’s contact and set them as the primary, could you give a bit more detail about how you got it to work?

You are using a PUT? Does that mean you aren’t using the action makePrimaryContact and if not what are you setting?

Did you have to add anything to you endpoint?

Hi ​@abrunner78 ,

I used the PUT method and included the Primary Contact ID in the request.

Method: PUT
Url: .../entity/Default/24.200.001/Customer

Sample Request:
{

    "CustomerID": {

        "value": "CUST000027"

    },

    "PrimaryContactID": {

        "value": 101043

    }

}

​@jinin, Thanks for you help. I was trying to do this on an older endpoint that didn’t include the “PrimaryContactID”. 

Now it’s working as expected. Thanks for your response.
