# Apollo.io

the platform reads your Apollo.io account's team members through the Apollo REST API so you can review who has access. the platform reviews Apollo teammates (account seats), not prospect or contact records.

:::caution
Use a **master API key** created in Apollo under **Settings** > **Integrations** > **API Keys** with **Set as master key** enabled. A **non-master, endpoint-scoped key** will **not** work, because the Get a List of Users endpoint that the platform reads is accessible only to master keys.
:::

## Prerequisites

- the platform organization administrator access
- The **Apollo account admin** role, or a permission profile that grants API key creation
- A **master API key** (created with the **Set as master key** toggle), since the platform reads the master-key-only Get a List of Users endpoint

## Step 1: Create an API Key

![Creating a master API key in Apollo settings](/docs/access-review/apollo-create-api-key.webp)

1. In Apollo (signed in as an account admin), go to **Settings** > **Integrations** > **API Keys** > **Create new key**.
2. Name the key (e.g. `Probo Access Review`) and toggle **Set as master key** so it can reach the Get a List of Users endpoint that the platform reads.
3. Save the key immediately and store it securely. Apollo may not show it again.

## Step 2: Connect in the platform

1. In the platform, go to **Access Reviews** > **Sources** > **Add Source**.
2. Find **Apollo.io**, click **API Key**, paste the key, and click **Connect**.

the platform names the source **Apollo.io** (the fixed provider name), since Apollo exposes no stable account-name endpoint. the platform pulls the account's members into your campaigns.

## Troubleshooting

- **Key rejected.** Confirm it's a master key created with **Set as master key** enabled. A non-master, endpoint-scoped key is rejected because the Get a List of Users endpoint is master-key-only.
- **No members appear.** The key must be created by an account admin (or a permission profile that grants API key creation) and belong to the Apollo account you're reviewing.
