I want to revoke/delete reward points from user

Have you tried entering a negative value for the awarded points?

I am planning to update the reward points by typeid & value in below code 

$core_v2_pointTransaction.UpdateByType("4b13bd57-5220-4769-ae7d-2d56b7dfe122", -10);

But it is not updated, Is there any mistake is there means please help me. Thanks!

If you want to revoke points create a new point transaction with a negative value, then you have to wait for recalculation

I am trying to create revoke points like below, but it is not created.

$core_v2_pointTransaction.Create("test data", 2100, -50, "86ec2193-76f8-4b3f-9e31-11e20bed1116", "ad2226ab-d59f-475c-9d22-4a79e3f0ec07", "%{ CreatedDate = $createdDateArg, TypeId = $typeIdArg }")

And it is not showing error and again it showing same create like below from script sandbox,

I don't know why the records not created with above syntax. Can you help me more please??
