@Marvin How would I access a parameter in the body of my webhook request inside a flow run?

To help you with accessing parameters in the body of a webhook request inside a flow run, I need to confirm which version of Prefect you're using. Could you please let me know whether you're using Prefect 2.x or 3.x? If you're not sure, I can proceed with the most recent version and we can adjust if necessary.

To access a parameter from the body of a webhook request inside a Prefect 2.x flow run, you can design your webhook to extract and use the required parameters. Here's a basic rundown on how you can do this: 1. Configure Webhook: Set up a webhook in Prefect that will receive POST requests. In the POST request body, you'll be sending the data or the parameters that you want to access in your Prefect flow. 2. Parse Webhook Payload: Within your flow function, you'll need to receive the webhook request and parse its body. Prefect doesn't automatically parse webhook bodies into flow parameters, so you might consider using a custom function or script to handle the request and trigger the flow with extracted parameters. 3. Access within Flow: Design your flow to accept parameters (e.g. using
@flow(run_config=...)
). After triggering the flow with parsed parameters from the webhook payload, your flow tasks can use these parameters for further processing. Here are some useful links from the Prefect documentation to guide you: - Webhooks Guide - Creating Interactive Workflows These resources will give you detailed insights on setting up webhooks and how to handle event-driven flows in Prefect 2.x.
