1. For implementing payloads/body on the request of each stream, you can refer to the [Request Options](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/request-options#request-options-1) section in the documentation. Unfortunately, the information extracts provided do not contain any additional examples or details on this topic. 2. To implement nested streams, you can use the

SubstreamPartitionRouter

. The information extracts provided do not contain a direct source code example for this, but you can refer to the [documentation on nested streams](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/partition-router#SubstreamPartitionRouter) for more information. Additionally, you can check out this [forum discussion](https://discuss.airbyte.io/t/1706) where a user implemented a similar approach using the Python CDK. Although it's not the low-code CDK, the logic might still be helpful for understanding how to implement nested streams. If you need more assistance or examples, I recommend visiting the [Airbyte documentation](https://docs.airbyte.com/), [tutorials](https://airbyte.io/tutorials), or [forum](https://discuss.airbyte.io/) for more information and support.
