Harvest authentication

This connector is optimized for AI agents. For the data replication connector, see Harvest.

This page documents the authentication and configuration options for the Harvest agent connector.

Authentication

Open source execution

In open source mode, you provide API credentials directly to the connector.

OAuth

credentials fields you need:

Field Name	Type	Required	Description
client_id	str	Yes	N/A
client_secret	str	Yes	N/A
refresh_token	str	Yes	Your Harvest OAuth2 refresh token
account_id	str	Yes	Your Harvest account ID

Example request:

from airbyte_agent_sdk.connectors.harvest import HarvestConnector
from airbyte_agent_sdk.connectors.harvest.models import HarvestOauth20AuthConfig

connector = HarvestConnector(
    auth_config=HarvestOauth20AuthConfig(
        client_id="<client_id>",
        client_secret="<client_secret>",
        refresh_token="<Your Harvest OAuth2 refresh token>",
        account_id="<Your Harvest account ID>"
    )
)

Token

credentials fields you need:

Field Name	Type	Required	Description
token	str	Yes	Your Harvest personal access token
account_id	str	Yes	Your Harvest account ID

Example request:

from airbyte_agent_sdk.connectors.harvest import HarvestConnector
from airbyte_agent_sdk.connectors.harvest.models import HarvestPersonalAccessTokenAuthConfig

connector = HarvestConnector(
    auth_config=HarvestPersonalAccessTokenAuthConfig(
        token="<Your Harvest personal access token>",
        account_id="<Your Harvest account ID>"
    )
)

Hosted execution

In hosted mode, you first create a connector via the Airbyte Agent API (providing your OAuth or Token credentials), then execute operations using either the Python SDK or API. If you need a step-by-step guide, see the developer quickstart.

OAuth

Create a connector with OAuth credentials.

credentials fields you need:

Field Name	Type	Required	Description
client_id	str	Yes	N/A
client_secret	str	Yes	N/A
refresh_token	str	Yes	Your Harvest OAuth2 refresh token
account_id	str	Yes	Your Harvest account ID

replication_config fields you need:

Field Name	Type	Required	Description
account_id	str	Yes	Your Harvest account ID. Required for all API requests.

Example request:

curl -X POST "https://api.airbyte.ai/api/v1/integrations/connectors" \
  -H "Authorization: Bearer <YOUR_BEARER_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace_name": "<WORKSPACE_NAME>",
    "connector_type": "Harvest",
    "name": "My Harvest Connector",
    "credentials": {
      "client_id": "<client_id>",
      "client_secret": "<client_secret>",
      "refresh_token": "<Your Harvest OAuth2 refresh token>",
      "account_id": "<Your Harvest account ID>"
    },
    "replication_config": {
      "account_id": "<Your Harvest account ID. Required for all API requests.>"
    }
  }'

Bring your own OAuth flow

To implement your own OAuth flow, use Airbyte's server-side OAuth API endpoints. For a complete guide, see Build your own OAuth flow.

Step 1: Initiate the OAuth flow

Request a consent URL for your user.

Field Name	Type	Required	Description
workspace_name	string	Yes	Your unique identifier for the workspace
connector_type	string	Yes	The connector type (e.g., "Harvest")
redirect_url	string	Yes	URL to redirect to after OAuth authorization

Example request:

curl -X POST "https://api.airbyte.ai/api/v1/integrations/connectors/oauth/initiate" \
  -H "Authorization: Bearer <YOUR_BEARER_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace_name": "<WORKSPACE_NAME>",
    "connector_type": "Harvest",
    "redirect_url": "https://yourapp.com/oauth/callback"
  }'

Redirect your user to the consent_url from the response.

Step 2: Handle the callback

After the user authorizes access, Airbyte automatically creates the connector and redirects them to your redirect_url with a connector_id query parameter. You don't need to make a separate API call to create the connector.

https://yourapp.com/oauth/callback?connector_id=<connector_id>

Extract the connector_id from the callback URL and store it for future operations. For error handling and a complete implementation example, see Build your own OAuth flow.

Token

Create a connector with Token credentials.

credentials fields you need:

Field Name	Type	Required	Description
token	str	Yes	Your Harvest personal access token
account_id	str	Yes	Your Harvest account ID

replication_config fields you need:

Field Name	Type	Required	Description
account_id	str	Yes	Your Harvest account ID. Required for all API requests.

Example request:

curl -X POST "https://api.airbyte.ai/api/v1/integrations/connectors" \
  -H "Authorization: Bearer <YOUR_BEARER_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace_name": "<WORKSPACE_NAME>",
    "connector_type": "Harvest",
    "name": "My Harvest Connector",
    "credentials": {
      "token": "<Your Harvest personal access token>",
      "account_id": "<Your Harvest account ID>"
    },
    "replication_config": {
      "account_id": "<Your Harvest account ID. Required for all API requests.>"
    }
  }'

Execution

After creating the connector, execute operations using either the Python SDK or API. If your Airbyte client can access multiple organizations, include organization_id in AirbyteAuthConfig and X-Organization-Id in raw API calls.

Python SDK

The connect() factory returns a fully typed HarvestConnector and reads AIRBYTE_CLIENT_ID / AIRBYTE_CLIENT_SECRET from the environment:
