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.

Hosted mode (most cases)

In hosted mode, create the connector through the Airbyte Agent CLI or API, then execute operations using the CLI, Python SDK, or API. If you need a step-by-step guide, see the developer quickstart.

OAuth

Use the CLI for hosted OAuth connector creation when possible. It opens the hosted setup flow and avoids passing connector secrets through the command line:

airbyte-agent login
airbyte-agent connectors create --json '{
  "workspace": "<your_workspace_name>",
  "name": "harvest"
}'

For API-first use cases, create a connector with OAuth credentials directly.

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.>"
    }
  }'

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 the CLI, Python SDK, or API. If your Airbyte client can access multiple organizations, set the default organization with airbyte-agent organizations use, include organization_id in AirbyteAuthConfig, or include X-Organization-Id in raw API calls.

CLI

Authenticate with Airbyte:

airbyte-agent login

Create the connector. The CLI opens the hosted setup flow:

airbyte-agent connectors create --json '{
  "workspace": "<your_workspace_name>",
  "name": "harvest"
}'

Describe the connector to see its supported entities and actions:

airbyte-agent connectors describe --json '{
  "workspace": "<your_workspace_name>",
  "name": "harvest"
}'

Execute an action:

airbyte-agent connectors execute --json '{
  "workspace": "<your_workspace_name>",
  "name": "harvest",
  "entity": "<entity>",
  "action": "<action>",
  "params": {}
}'

Python SDK

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