+# Notion Source
+
+This is the repository for the Notion source connector, written in Python.
+For information about how to use this connector within Airbyte, see [the documentation](https://docs.airbyte.io/integrations/sources/notion).
+
+## 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-notion:build
+```
+
+#### Create credentials
+**If you are a community contributor**, follow the instructions in the [documentation](https://docs.airbyte.io/integrations/sources/notion)
+to generate the necessary credentials. Then create a file `secrets/config.json` conforming to the `source_notion/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 notion 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-notion:dev
+```
+
+You can also build the connector image via Gradle:
+```
+./gradlew :airbyte-integrations:connectors:source-notion: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-notion:dev spec
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/source-notion:dev check --config /secrets/config.json
+docker run --rm -v $(pwd)/secrets:/secrets airbyte/source-notion:dev discover --config /secrets/config.json
+docker run --rm -v $(pwd)/secrets:/secrets -v $(pwd)/integration_tests:/integration_tests airbyte/source-notion: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-notion:unitTest
+```
+To run acceptance and custom integration tests:
+```
+./gradlew :airbyte-integrations:connectors:source-notion: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.

+# Notion
+
+## Overview
+
+Notion is an application that provides components such as notes, databases, kanban boards, wikis, calendars and reminders. Notion REST API allows a developer to retrieve pages, databases, blocks, and users on the Notion platform.
+
+## Endpoints
+
+Notion API consists of three endpoints which can be extracted data from:
+
+1. **User**: The User object represents a user in a Notion workspace. Users include guests, full workspace members, and bots.
+2. **Block**: A block object represents content within Notion. Blocks can be text, lists, media, and more. Page and database is also a type of block.
+3. **Search**: This endpoint is used to get list of pages and databases.
+
+## Quick Notes
+
+- Notion stores content in hierarchy, each node is called a 'block'. Block is a generic term which can be text, lists, media, even page and database are also block.
+
+- Due to this hierarchical structure, we use recursive request to get the full list of blocks.
+
+- Pages and databases can be extracted from the `Search` endpoint separately, so they are excluded from the block list request.
+
+- Airbyte CDK doesn't support recursive schema, so some elements of the block schema which can be recursive are replaced with empty objects.
+
+- Page and database must grant permission to the internal integration, otherwise API cannot extract data from them. See [https://developers.notion.com/docs/authorization#authorizing-internal-integrations](https://developers.notion.com/docs/authorization#authorizing-internal-integrations)
+
+- Rate limiting is a standard exponential backoff when a 429 HTTP status code returned. The rate limit for incoming requests is an average of 3 requests per second. Some bursts beyond the average rate are allowed. Notion API also has size limit, see [https://developers.notion.com/reference/errors#request-limits](https://developers.notion.com/reference/errors#request-limits)
+
