# Post Call Analysis – Call Analysis Flow 🔀
#### Select Call Analysis Flow
Click on “Select Call Analysis Flow”
You will only see flows that meet the specific criteria for call analysis. If your flow doesn’t appear in the list, it’s because it doesn’t meet the following conditions:
* The flow must have a “Trigger” type that receives all parameters through the body of the request.
* The flow must respond with text, since LLM models can only process text-based responses.
* Only one analysis flow can be selected in this feature.
Once the flow is selected, you’ll see the flow’s URL and API Key already filled in under the “Call Analysis Flow” field.
⚠️ Warning:
If you change the name of a flow, you must update the corresponding webhook URL.
