Step 3: Define Inputs
Each connector declares the inputs it needs to read data from the underlying data source. This is the Airbyte Protocol's
The simplest way to implement this is by creating a
spec.yaml file in
source_<name>/spec.yaml which describes your connector's inputs according to the ConnectorSpecification schema. This is a good place to start when developing your source. Using JsonSchema, define what the inputs are (e.g. username and password). Here's an example of what the
spec.yaml looks like for the Stripe API source.
For more details on what the spec is, you can read about the Airbyte Protocol here.
The generated code that Airbyte provides, handles implementing the
spec method for you. It assumes that there will be a file called
spec.yaml in the same directory as
source.py. If you have declared the necessary JsonSchema in
spec.yaml you should be done with this step.
Given that we'll pulling currency data for our example source, we'll define the following
title: Python Http Tutorial Spec
description: API access key used to retrieve data from the Exchange Rates API.
description: Start getting data from that date.
description: "ISO reference currency. See <a href=\"https://www.ecb.europa.eu/stats/policy_and_exchange_rates/euro_reference_exchange_rates/html/index.en.html\">here</a>."
In addition to metadata, we define two inputs:
access_key: The API access key used to authenticate requests to the API
start_date: The beginning date to start tracking currency exchange rates from
base: The currency whose rates we're interested in tracking
