Frequently Asked Questions
Didn't find your answer? Please don't hesitate to reach out.
The Harvest connector supports Personal Access Token authentication. You provide your Harvest personal access token and your Harvest account ID directly via the HarvestPersonalAccessTokenAuthConfig. In hosted mode, credentials are stored securely in Airbyte Cloud using AirbyteAuthConfig with your Airbyte client credentials.
Can I use this connector with any AI agent framework?
The connector is compatible with any Python-based AI agent framework including LangChain, LlamaIndex, CrewAI, Pydantic AI, and custom implementations.
Does this connector support write operations?
Currently, the Harvest connector focuses on read operations only. Write operations such as creating time entries, updating project budgets, deleting invoices, or starting timers are not supported at this time.
How is this different from the Airbyte data connector?
Agent connectors are specifically designed for AI agents and LLM applications. They provide natural language interfaces, optimized response formats, and seamless integration with agent frameworks, unlike traditional ETL-focused connectors.
Will there be a platform for agent connectors?
The hosted version with secure credential storage through Airbyte Cloud is already available. See the hosted usage section in the documentation for setup instructions.
