+# Linnworks Source
+
+This is the repository for the Linnworks source connector, written in Python.
+For information about how to use this connector within Airbyte, see [the documentation](https://docs.airbyte.io/integrations/sources/linnworks).
+
+## Local development
+
+### Prerequisites
+**To iterate on this connector, make sure to complete this prerequisites section.**
+
+#### Minimum Python version required `= 3.7.0`
+
+#### Build & Activate Virtual Environment and install dependencies
+From this connector directory, create a virtual environment:
+```
+python -m venv .venv
+```
+
+This will generate a virtualenv for this module in `.venv/`. Make sure this venv is active in your
+development environment of choice. To activate it from the terminal, run:
+```
+source .venv/bin/activate
+pip install -r requirements.txt
+pip install '.[tests]'
+```
+If you are in an IDE, follow your IDE's instructions to activate the virtualenv.
+
+Note that while we are installing dependencies from `requirements.txt`, you should only edit `setup.py` for your dependencies. `requirements.txt` is
+used for editable installs (`pip install -e`) to pull in Python dependencies from the monorepo and will call `setup.py`.
+If this is mumbo jumbo to you, don't worry about it, just put your deps in `setup.py` but install using `pip install -r requirements.txt` and everything
+should work as you expect.
+
+#### Building via Gradle
+You can also build the connector in Gradle. This is typically used in CI and not needed for your development workflow.
+
+To build using Gradle, from the Airbyte repository root, run:
+```
+./gradlew :airbyte-integrations:connectors:source-linnworks:build
+```
+
+#### Create credentials
+**If you are a community contributor**, follow the instructions in the [documentation](https://docs.airbyte.io/integrations/sources/linnworks)
+to generate the necessary credentials. Then create a file `secrets/config.json` conforming to the `source_linnworks/spec.json` file.
+Note that any directory named `secrets` is gitignored across the entire Airbyte repo, so there is no danger of accidentally checking in sensitive information.
+See `integration_tests/sample_config.json` for a sample config file.
+
+**If you are an Airbyte core member**, copy the credentials in Lastpass under the secret name `source linnworks test creds`
+and place them into `secrets/config.json`.
+
+### Locally running the connector
+```
+python main.py spec
+python main.py check --config secrets/config.json
+python main.py discover --config secrets/config.json
+python main.py read --config secrets/config.json --catalog integration_tests/configured_catalog.json
+```
+
+### Locally running the connector docker image
+
+#### Build
+First, make sure you build the latest Docker image:
+```
+docker build . -t airbyte/source-linnworks:dev
+```
+
+You can also build the connector image via Gradle:
+```
+./gradlew :airbyte-integrations:connectors:source-linnworks:airbyteDocker
+```
+When building via Gradle, the docker image name and tag, respectively, are the values of the `io.airbyte.name` and `io.airbyte.version` `LABEL`s in
+the Dockerfile.
+
+#### Run
+Then run any of the connector commands as follows:
+```
+docker run --rm airbyte/source-linnworks:dev spec
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/source-linnworks:dev check --config /secrets/config.json
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/source-linnworks:dev discover --config /secrets/config.json
+docker run --rm -v $(pwd)/secrets:/secrets -v $(pwd)/integration_tests:/integration_tests airbyte/source-linnworks:dev read --config /secrets/config.json --catalog /integration_tests/configured_catalog.json
+```
+## Testing
+Make sure to familiarize yourself with [pytest test discovery](https://docs.pytest.org/en/latest/goodpractices.html#test-discovery) to know how your test files and methods should be named.
+First install test dependencies into your virtual environment:
+```
+pip install .[tests]
+```
+### Unit Tests
+To run unit tests locally, from the connector directory run:
+```
+python -m pytest unit_tests
+```
+
+### Integration Tests
+There are two types of integration tests: Acceptance Tests (Airbyte's test suite for all source connectors) and custom integration tests (which are specific to this connector).
+#### Custom Integration tests
+Place custom tests inside `integration_tests/` folder, then, from the connector root, run
+```
+python -m pytest integration_tests
+```
+#### Acceptance Tests
+Customize `acceptance-test-config.yml` file to configure tests. See [Source Acceptance Tests](https://docs.airbyte.io/connector-development/testing-connectors/source-acceptance-tests-reference) for more information.
+If your connector requires to create or destroy resources for use during acceptance tests create fixtures for it and place them inside integration_tests/acceptance.py.
+To run your integration tests with acceptance tests, from the connector root, run
+```
+python -m pytest integration_tests -p integration_tests.acceptance
+```
+To run your integration tests with docker
+
+### Using gradle to run tests
+All commands should be run from airbyte project root.
+To run unit tests:
+```
+./gradlew :airbyte-integrations:connectors:source-linnworks:unitTest
+```
+To run acceptance and custom integration tests:
+```
+./gradlew :airbyte-integrations:connectors:source-linnworks:integrationTest
+```
+
+## Dependency Management
+All of your dependencies should go in `setup.py`, NOT `requirements.txt`. The requirements file is only used to connect internal Airbyte dependencies in the monorepo for local development.
+We split dependencies between two groups, dependencies that are:
+* required for your connector to work need to go to `MAIN_REQUIREMENTS` list.
+* required for the testing need to go to `TEST_REQUIREMENTS` list
+
+### Publishing a new version of the connector
+You've checked out the repo, implemented a million dollar feature, and you're ready to share your changes with the world. Now what?
+1. Make sure your changes are passing unit and integration tests.
+1. Bump the connector version in `Dockerfile` -- just increment the value of the `LABEL io.airbyte.version` appropriately (we use [SemVer](https://semver.org/)).
+1. Create a Pull Request.
+1. Pat yourself on the back for being an awesome contributor.
+1. Someone from Airbyte will take a look at your PR and iterate with you to merge it into master.

+# Linnworks
+
+Linnworks is an e-commerce sales channel and fulfillment integration platform.
+
+The platform has two portals: seller and developer. First, to create API credentials, log in to the [developer portal](https://developer.linnworks.com) and create an application of type `System Integration`. Then click on provided Installation URL and proceed with an installation wizard. The wizard will show a token that you will need for authentication. The installed application will be present on your account on [seller portal](https://login.linnworks.net/).
+
+Authentication credentials can be obtained on developer portal section Applications -> _Your application name_ -> Edit -> General. And the token, if you missed it during the install, can be obtained anytime under the section Applications -> _Your application name_ -> Installs.
+
+Authentication flow is similar to OAuth2. The only notable difference is that the authentication endpoint returns a dynamic API server URL that is later used for subsequent requests.
+
+For paginated results, all streams use max page size. Upstream pagination type [GenericPagedResult](https://apps.linnworks.net/Api/Class/linnworks-spa-commondata-Generic-GenericPagedResult) is implemented in class `LinnworksGenericPagedResult`. However, some endpoints use ad-hoc pagination styles, which are implemented directly in respective streams.
+
+The API uses a standard HTTP 429 status code and `Retry-After` header for rate limiting. Its value is used for exponential backoff.
+
+Linnworks API design is somewhat inconsistent and doesn't follow REST practice for providing uniform endpoints for every resource and collection of the resources. For example, collection endpoint sometimes returns only a part of resource attributes while specific resource endpoint returns all of them. In this case, N+1 requests are the only way to retrieve all attributes of all the resources of the same kind.
+
+## Processed Orders
+
+ProcessedOrders stream emits variable-length slice time intervals depending on the sync period. Too short, e.g., hourly interval severely reduces initial sync performance by issuing too many requests. On the other hand, too long, e.g., yearly, prevents the creation of state events.
+
+The optimal slice time interval should yield the number of records equal to the max page size, i.e., 500. In such a case, the stream would emit a state event after each HTTP request, minimizing the number of requests and preventing repeated fetch of already fetched data in case of failure or scheduled syncs.
+
+However, the slice time interval highly depends on the nature of upstream data and may substantially vary between different accounts. For example, consider one luxury items seller who sells a dozen items every week and another who sells thousands of items each day. The number of their processed orders in any time interval is several orders of magnitude apart.
+
+Current intervals are chosen purely speculatively. Therefore, they might be inappropriate for some sellers and would need adjustment.
