Yes, you can configure a stream to use a POST call instead of GET in the Python CDK by overriding the

request_method

property in your stream class. By default, it uses the GET method, but you can change it to POST or any other HTTP method as per your requirements. Here is a basic example of how you can do it:

python class MyStream(HttpStream):     ...     @property     def request_method(self) -> str:         """         Override this method if your HTTP requests use a method other than GET.         """         return "POST"     ...

In the

MyStream

class, the

request_method

property is overridden to return "POST", which means that this stream will use the POST method for HTTP requests. For more details, you can refer to the [Airbyte documentation](https://docs.airbyte.com/connector-development/cdk-python/http-streams).

Yes, you can enable detailed logging to see the exact payload being sent to your source. This can be done by setting the

LOG_LEVEL

environment variable to

DEBUG

when starting Airbyte. This will log all HTTP requests and responses, including their bodies, which can help you identify what's causing the 400 error. Here is an example of how to use it:

bash LOG_LEVEL=DEBUG VERSION=dev docker compose up

This command will start Airbyte with debug-level logging enabled. Please note that enabling debug logging will significantly increase the amount of log output, so it's recommended to use it only for debugging purposes. For more details, you can refer to the [Airbyte documentation](https://docs.airbyte.com/contributing-to-airbyte/resources/developing-locally).
