It is a very easy to set up though pretty powerful tool with support for delays and handling query params.
It also has a console for checking all the requests and corresponding responses matched.
Here it is https://github.com/jmartin82/mmock.

Below I describe a way to use it with docker-compose for local development.

./assets/mock_servers/service1/validation.yaml

request:
  description: "Handlingvalidation"
  method: GET
  path: "/api/v5/groupie/validate_participant/*"
response:
  statusCode: 200
  headers:
    Content-Type:
      - "application/json"
  body: >
    {
      "data": {
        "groupie_id": "",
        "host": {
          "name": "John Doe",
          "code": "w3er"
        }
      }
    }

./docker-compose.yml

...
  service1:
    container_name: service1
    hostname: service1
    image: jordimartin/mmock
    ports:
      - "8011:8083" # server port
      - "9011:8082" # console port
    volumes:
      - ./assets/mock_servers/service1:/config
    networks:
      - my-network
...

Then inside other containers you can request it as
curl -X GET "http://service1:8083/api/v5/groupie/validate_participant/111".
From your host machine you can request it as
curl -X GET "http://localhost:8011/api/v5/groupie/validate_participant/111".
And if you open http://localhost:9011/, you will see this request being matched by the config your provided.
