# API Access

Connect your own systems to Tahua using the API. Create OAuth credentials and use them to authenticate API requests.

Tahua's REST API lets your own systems, such as reporting dashboards or a CRM, read your organisation's data programmatically. Access uses OAuth 2.0 client credentials that an administrator creates and manages from the **API & MCP** tab in **Settings > Organisation** (previously called **API Access**).

{% hint style="info" %}
You will need an administrator account with the **Can manage Integrations** permission to create or delete API credentials.
{% endhint %}

Want to ask questions about your data in an AI assistant such as Claude instead? See [AI Assistant Access (MCP)](/knowledge-base/integrations-help-guides/ai-assistant-access.md). It is managed from the same **API & MCP** tab.
