How should I structure the requester portion of a connector's yaml file to allow for multiple headers? Is this correct? base_requester: type: HttpRequester url_base: https://www.gottman.com/wp-json/wc/v3 http_method: GET request_headers: User-Agent: Airbyte-WooCommerce-Connector/1.0 authenticator: type: ApiKeyAuthenticator header: Authorization api_token: <redacted>

Your structure for the requester portion of a connector's YAML file is close, but there are a few adjustments we can make to ensure it's correctly formatted and includes multiple headers. Here's how you can structure it:
Copy code
yaml requester:   type: HttpRequester   url_base: "<https://www.gottman.com/wp-json/wc/v3>"   http_method: GET   request_options_provider:     request_headers:       User-Agent: Airbyte-WooCommerce-Connector/1.0   authenticator:     type: ApiKeyAuthenticator     header: Authorization     api_token: "{{ config['api_key'] }}"
Let's break down the changes and explain the structure: 1. The top-level key should be
requester
instead of
base_requester
[Requester](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/requester). 2. To include multiple headers, we use the
request_options_provider
with a
request_headers
subsection [Request Options Provider](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/request-options#request-options-provider). 3. The
authenticator
is correctly placed at the same level as other requester properties. 4. For the
api_token
, it's a good practice to use a configuration variable instead of hardcoding the value. The example shows how to reference a config variable [ApiKeyAuthenticator](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/reference#/definitions/ApiKeyAuthenticator). With this structure, you can easily add more headers under the
request_headers
section if needed. For example:
Copy code
yaml request_options_provider:   request_headers:     User-Agent: Airbyte-WooCommerce-Connector/1.0     Accept: application/json     Content-Type: application/json
This setup allows for multiple headers while keeping the authentication separate, which is handled by the
ApiKeyAuthenticator
.

for testing purposes I'm hardcoding variables though, that's fine, right?
And this should be in line with the "definitions" section, or underneath it? @kapa.ai

To answer your question accurately, I need more context about what specific part of the Airbyte configuration you're referring to. However, based on the information provided in the knowledge sources, I can give you some general guidance about the structure of Airbyte's YAML configuration files. In Airbyte's low-code connector development framework, the YAML file typically has a specific structure. The "definitions" section is usually one of the top-level components in this structure. According to the [Low-code connector development documentation](https://docs.airbyte.com/connector-development/config-based/low-code-cdk-overview#configuring-the-yaml-file), the main components of the YAML file are: 1.
version
2.
definitions
3.
streams
4.
check
5.
spec
The "definitions" section is used to describe objects that can be reused throughout the YAML connector. Other components like
streams
,
check
, and
spec
are typically at the same level as
definitions
, not underneath it. If you're asking about a specific element and where it should be placed in relation to the "definitions" section, you would need to provide more details about that element. Different components have different placements within the YAML structure. For a more precise answer, could you please provide more context about what specific part of the configuration you're asking about?

Based on the information provided in the knowledge sources, I can explain the structure you've shown in your question. This appears to be the beginning of an Airbyte connector configuration YAML file. The structure you've provided is correct and follows the general layout of an Airbyte low-code connector YAML file. Let's break it down: 1. `version: 5.7.5`: This line specifies the version of the Airbyte CDK used to build and test the source. It should be at the top of the file [as shown in the DeclarativeSource reference](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/reference). 2. `type: DeclarativeSource`: This indicates that this is a declarative source configuration. 3. `check:`: This section defines how to test the connection to the source. It's correctly placed at the top level of the YAML structure [as described in the documentation](https://docs.airbyte.com/connector-development/config-based/low-code-cdk-overview#configuring-the-yaml-file). 4. `definitions:`: This section is used to describe objects that will be reused in the YAML connector. It's also correctly placed at the top level. 5. `streams:`: This section lists the streams of the source, which is also correct according to the documentation. The structure you've provided aligns with the general layout described in the [Low-code connector development documentation](https://docs.airbyte.com/connector-development/config-based/low-code-cdk-overview#configuring-the-yaml-file):
Copy code
yaml version: "0.1.0" definitions:   <key-value pairs defining objects which will be reused in the YAML connector> streams:   <list stream definitions> check:   <definition of connection checker> spec:   <connector spec>
Your configuration follows this structure, although the order is slightly different (with
check
before
definitions
). This order difference is not problematic, as long as all the required top-level components are present. Remember that each stream configuration (like your
orders
stream) should be properly indented under the
streams
section, and each component within the stream (like
retriever
and
paginator
) should be correctly nested. If you need to add more streams or components, make sure to maintain the correct indentation and structure as you've started here.

ah, sorry, I'm wondering what value the text you provided me earlier (requester: type: HttpRequester url_base: "https://www.gottman.com/wp-json/wc/v3" http_method: GET request_options_provider: request_headers: User-Agent: Airbyte-WooCommerce-Connector/1.0 authenticator: type: ApiKeyAuthenticator header: Authorization api_token: "{{ config['api_key'] }}") should be under @kapa.ai

I understand you're asking about where to place the
requester
configuration in the Airbyte YAML file structure. Based on the knowledge sources provided, I can give you a clear answer. The
requester
configuration you've shared should be placed under the
retriever
section of a stream definition. Specifically, it should be part of the
HttpRequester
component, which is typically used within a stream's data retriever. According to the [Requester documentation](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/requester), the
HttpRequester
is part of the data retriever, which "Describes how to retrieve data from the API." Here's how it would typically fit into the YAML structure:
Copy code
yaml streams:   - name: your_stream_name     retriever:       type: SimpleRetriever       requester:         type: HttpRequester         url_base: "<https://www.gottman.com/wp-json/wc/v3>"         http_method: GET         request_options_provider:           request_headers:             User-Agent: Airbyte-WooCommerce-Connector/1.0         authenticator:           type: ApiKeyAuthenticator           header: Authorization           api_token: "{{ config['api_key'] }}"
This structure aligns with the [HttpRequester reference](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/reference#/definitions/HttpRequester) and the general layout of stream configurations in Airbyte's low-code CDK. Remember, this
requester
configuration should be properly indented under the
retriever
section of your specific stream definition, not at the top level of the YAML file.

so if there's multiple endpoints the connector hits, I need to update every single stream with the requester information? @kapa.ai

Yes, you're correct. If your connector needs to hit multiple endpoints, you typically need to configure the
requester
information for each stream that corresponds to a different endpoint. However, Airbyte provides ways to make this process more efficient and reduce repetition in your YAML configuration. Here are a few key points to consider: 1. Individual Stream Configuration: Each stream in your connector can have its own
requester
configuration, allowing you to specify different endpoints, HTTP methods, or authentication methods as needed for each API endpoint. 2. Reusable Definitions: To avoid repetition, you can use the
definitions
section of your YAML file to create reusable components. This is particularly useful for common configurations like authentication or base URL settings. For example:
Copy code
yaml    definitions:      requester:        $ref: "#/definitions/requester"
You can then reference this definition in your stream configurations [as shown in the tutorial example](https://docs.airbyte.com/connector-development/config-based/tutorial/connecting-to-the-API-source#updating-the-connector-definition). 3. Base Stream: If many of your streams share common configurations, you can define a base stream and have other streams inherit from it. This is often done using the
$ref
keyword:
Copy code
yaml    definitions:      base_stream:        retriever:          $ref: "#/definitions/retriever"        streams:      - $ref: "#/definitions/base_stream"        $parameters:          name: "stream_name"          path: "/specific/endpoint"
This approach is demonstrated in the [incremental reads tutorial](https://docs.airbyte.com/connector-development/config-based/tutorial/incremental-reads). 4. Partition Router: For cases where you need to fetch data from multiple related endpoints, you might consider using a
PartitionRouter
. This allows you to specify a set of parameters that will be iterated upon when making requests, which can be useful for hitting multiple related endpoints [as described in the documentation](https://docs.airbyte.com/connector-development/config-based/understanding-the-yaml-file/yaml-overview#routing-to-data-that-is-partitioned-in-multiple-locations). By leveraging these features, you can efficiently configure your connector to handle multiple endpoints while minimizing repetition in your YAML file. However, you'll still need to ensure that each stream is properly configured for its specific endpoint requirements.

ok cool, this was what I was looking for: 2. Reusable Definitions: To avoid repetition, you can use the
definitions
section of your YAML file to create reusable components. This is particularly useful for common configurations like authentication or base URL settings. For example:
Copy code
definitions:
     requester:
       $ref: "#/definitions/requester"

I'm glad I could provide the information you were looking for. Yes, using reusable definitions is an excellent way to keep your YAML configuration DRY (Don't Repeat Yourself) and more manageable, especially when dealing with multiple streams that share common configurations. To expand on this concept, let me provide a more detailed example of how you might use reusable definitions for your requester configuration. Based on the [Low-code connector development documentation](https://docs.airbyte.com/connector-development/config-based/low-code-cdk-overview#configuring-the-yaml-file), you could structure your YAML file like this:
Copy code
yaml definitions:   requester:     type: HttpRequester     url_base: "<https://www.gottman.com/wp-json/wc/v3>"     http_method: GET     request_options_provider:       request_headers:         User-Agent: Airbyte-WooCommerce-Connector/1.0     authenticator:       type: ApiKeyAuthenticator       header: Authorization       api_token: "{{ config['api_key'] }}"  streams:   - name: stream1     retriever:       $ref: "#/definitions/requester"       path: "/endpoint1"   - name: stream2     retriever:       $ref: "#/definitions/requester"       path: "/endpoint2"
In this setup, you define the common requester configuration once in the
definitions
section, and then reference it in each stream using
$ref: "#/definitions/requester"
. You can then override or add specific properties (like the
path
) for each stream as needed. This approach allows you to maintain a single source of truth for your common configurations while still providing flexibility for stream-specific adjustments. It's particularly useful when you have multiple streams that share the same base URL, authentication method, and other request properties, but differ in their specific endpoints or parameters. Remember, you can create reusable definitions for other components as well, not just the requester. This can include things like paginators, record selectors, or even entire stream configurations that you want to reuse or extend. </assistant_answer>
