Here are the fields that are accessible/inaccessible via the Affinity API, broken down by our three entity types: **Organization**, **Person**, and **Opportunity**. Learn more by visiting our respective API documentation for [API V1](https://api-docs.affinity.co/#introduction) and [API V2](https://developer.affinity.co/docs/v2/). **Important Callout**: If you're currently trialing Affinity, you will **not** be able to access Affinity's API V1 or API V2 until you purchase an Affinity subscription to one of the following tiers: **Scale**, **Advanced**, or **Enterprise** (see [Getting started with the Affinity API + FAQs](/s/article/Getting-started-with-the-Affinity-API-faqs)). ## Who has access to Affinity API V1 and API V2? | Subscription Tier | Access to API V1 | Access to API V2 | | ----------------- | ---------------- | ---------------- | | **Essential** | No | No | | **Scale** | Yes | Yes | | **Advanced** | Yes | Yes | | **Enterprise** | Yes | Yes | ## Which fields are accessible, but not editable?
