Valid yaml example for training via rest api

[mloubser (Melinda Loubser)]

It is possible, but the documentation is not clear. See these issues:

Update API spec for training endpoint

Training a new rasa model from http-api using example provided fails.

Rasa 2.0 - API /model/train doesn't work

Hi @mbukovy, it appears our documentation is in need of an update to match the YAML spec. You can use the /model/train endpoint with YAML by setting the request header’s Content-Type to application/x-yaml. Inside the request body, you’ll pass in a single YAML formatted string containing the configuration, domain definitions, and training data. For example: stories: - story: My story steps: - intent: greet - action: utter_greet rules: - rule: My rule steps: - intent: greet - actio…

Try this:

curl --request POST \
  --url http://localhost:5005/model/train \
  --header 'Content-Type: application/x-yaml' \
  --data '---
intents:
  - greet
language: en
nlu:
  - examples: |
        - hi
        - hello
    intent: greet
  - examples: |
        - goodbye
        - bye
    intent: bye
