# Agent with Zapier NLA Integration

Full docs here: https://nla.zapier.com/start/

**Zapier Natural Language Actions** gives you access to the 5k+ apps and 20k+ actions on Zapier's platform through a natural language API interface.

NLA supports apps like Gmail, Salesforce, Trello, Slack, Asana, HubSpot, Google Sheets, Microsoft Teams, and thousands more apps: https://zapier.com/apps

Zapier NLA handles ALL the underlying API auth and translation from natural language --> underlying API call --> return simplified output for LLMs. The key idea is you, or your users, expose a set of actions via an oauth-like setup window, which you can then query and execute via a REST API.

NLA offers both API Key and OAuth for signing NLA API requests.

Server-side (API Key): for quickly getting started, testing, and production scenarios where LangChain will only use actions exposed in the developer's Zapier account (and will use the developer's connected accounts on Zapier.com)

User-facing (Oauth): for production scenarios where you are deploying an end-user facing application and LangChain needs access to end-user's exposed actions and connected accounts on Zapier.com

Attach NLA credentials via either an environment variable (`ZAPIER_NLA_OAUTH_ACCESS_TOKEN` or `ZAPIER_NLA_API_KEY`) or refer to the params argument in the API reference for `ZapierNLAWrapper`.

The example below demonstrates how to use the Zapier integration as an Agent:
