The challenge we had with that approach was being able to reference the response of a previous request. As a simple example: 1. Create customer 2. Add tokenized card to customer 3. Charge the card Step 2 requires the HREF/ID of the customer. Step 3 requires the HREF/ID of the card.

Yeah, I realized the same thing; this aspect really makes it harder to keep the system simple, naturally. I've thought about different ways of approaching this, considering chained requests as a possibility.

  Here's an example of how we do it: The scenario: https://github.com/balanced/balanced-api/blob/master/features/rest/push_to_card.feature#L51 https://github.com/balanced/balanced-api/blob/master/feature...: Scenario: Push money to an existing debit card Given I have sufficient funds in my marketplace And I have a tokenized debit card When I POST to /cards/:debit_card_id/credits with the JSON API body: """ { "credits": [{ "amount": 1234 }] } """ Then I should get a 201 Created status code And the response is valid according to the "credits" schema And the fields on this credit match: """ { "status": "succeeded" } """ And the credit was successfully created There's several things in there like "And I have a tokenized debit card" that setup the scenario to be able to do things like "/cards/:debit_card_id/credits", which refers to an actual card ID created in the test API.

    That's really quite impressive! I hadn't realized that you meant that an endpoint can be referenced "in the abstract" without explicit parameters, which makes for much easier integration. For some reason, though, I feel like the natural language would actually intimidate me. Where are ideas like "sufficient funds" defined?

      "I have sufficient funds in my marketplace" is defined here: https://github.com/balanced/balanced-api/blob/master/features/step_definitions/cards.rb#L89 https://github.com/balanced/balanced-api/blob/master/feature... Given(/^I have sufficient funds in my marketplace$/) do step 'I have tokenized a card' @client.post("/cards/#{@card_id}/debits", { amount: 500000 }) end Here's another example from the scenario above: Given(/^I have a tokenized debit card$/) do @client.post('/cards', { name: "Johannes Bach", number: "4342561111111118", expiration_month: "05", expiration_year: "2015" } ) @debit_card_id = @client['cards']['id'] @client.add_hydrate(:debit_card_id, @debit_card_id) end
