I have no Idea what to do here it just says bummer! Try again (not a very helpful error message )

Great! Now that we have the Blueprint, it's time to create the actual Api instance and register the resources for it. Create a new variable named api in each of the resources that's an Api instance for the Blueprint. Then add both of the Resources to api. You can use whatever endpoint name you want, but make sure the URL pattern is like "/api/v1/[PLURAL RESOURCE]". Remember to include the id argument in the appropriate URLs.

api.py 
from flask import Flask

app = Flask(__name__)


if __name__ == '__main__':
    app.run()
resources/ingredients.py 
from flask import Blueprint
from flask.ext.restful import Resource, Api

import models


class IngredientList(Resource):
    def get(self):
        return 'IngredientList'


class Ingredient(Resource):
    def get(self, id):
        return 'Ingredient'

ingredients_api=Blueprint('resources.ingredients', __name__)

api = Api(ingredients_api)

api.add_resource(IngredientList, '/api/v1/ingredients', endpoint='ingredients')

api.add_resource(Ingredient, '/api/v1/ingredients/<int:id>', endpoint='ingredient')
resources/recipes.py 
from flask import Blueprint
from flask.ext.restful import Resource, Api

import models


class RecipeList(Resource):
    def get(self):
        return 'RecipeList'


class Recipe(Resource):
    def get(self, id):
        return 'Recipe'

recipes_api=Blueprint('resources.recipes', __name__)

api = Api(recipes_api)

api.add_resources(RecipeList, '/api/v1/recipes', endpoint='recipes')

api.add_resources(Recipe, '/api/v1/recipes/<int:id>', endpoint='recipe')

Hey Rodi,

You might have figured it out since this is 2 months old, but in case other people struggle here is my solution.

api.py

from flask import Flask

from resources.ingredients import ingredients_api
from resources.recipes import recipes_api

app = Flask(__name__)
app.register_blueprint(ingredients_api)
app.register_blueprint(recipes_api)

if __name__ == '__main__':
    app.run()

resources/ingredients

ingredients_api = Blueprint('resources.ingredients',__name__)
api = Api(ingredients_api)
api.add_resource(
    IngredientList,
    '/api/v1/ingredients',
    endpoint='ingredients'
)
api.add_resource(
    Ingredient,
    '/api/v1/ingredients/<int:id>',
    endpoint='ingredient'
)

resources/recipes

recipes_api = Blueprint('resources.recipes',__name__)   
api = Api(recipes_api)
api.add_resource(
    RecipeList,
    '/api/v1/recipes',
    endpoint='recipes'
)
api.add_resource(
    Recipe,
    '/api/v1/recipes/<int:id>',
    endpoint='recipe'
)

In ingredients.py correctly space ingredients_api=Blueprint. In recipes.py change api.add_resources to api.add_resource (both times)
