Boto3 DynamoDB Client: Use batch_write_item or put_item with regular JSON structure, not dynamoDB JSON

Question

I am using boto3 version 1.26.90 with python 3.10 and attempting to add a new object to a dynamoDB table. Dynamo has their own JSOn structure for table entries, where the type of the field is added so "key":"value" becomes "key":{"SS":"value"}. when using this version of boto3, it does not accept the classic json structure. I get an error saying Invalid type for parameter, type: <class 'str'>, valid types <class 'dict'>

I want to find a way to upload regularly structured json or an existing python method that will transform the data for me instead of me adding a programmatic transformation

Accepted Answer

To use native JSON you have two choices:

- Use the `Table` level [Resource client](https://boto3.amazonaws.com/v1/documentation/api/latest/reference/services/dynamodb/table/index.html)
- Marshall your JSON into DDB JSON first using [Type Serializer](https://boto3.amazonaws.com/v1/documentation/api/latest/_modules/boto3/dynamodb/types.html)

Both of which you can read more about in this [Blog Post](https://aws.amazon.com/blogs/database/exploring-amazon-dynamodb-sdk-clients/)
