## Apollo integration

Apollo is a sales intelligence and engagement platform for finding, enriching, and reaching out to contacts and companies, with built-in email sequences, calling, and deal tracking.

Agen.co connects to Apollo through Apollo's own hosted MCP server as an **Official** connector. Each user authorizes with their own Apollo account, and agents get the access that account already has in Apollo.

Prerequisites
- An Apollo account. Free accounts registered with a personal email address can't use people or company search and enrichment, retrieve full people or company records, match contacts, or add people to prospect lists — these need an account on a plan that includes them.
- A sufficient Apollo credit balance for enrichment calls. Company search, company enrichment, people enrichment, and reading company job postings all draw from the account's credits, whether called one at a time or in bulk. Every other tool — contact and account CRUD, sequences, tasks, calls, and analytics — doesn't use credits.


Adding contacts to a sequence can send real email
Adding a contact to an active Apollo sequence can trigger that sequence's outbound emails automatically, the same as doing it from the Apollo UI. Scope the [policy](/agen-for-work/policies/overview) for this connector carefully if your agents shouldn't be able to start outreach on their own.

Use a short Instance Slug — the default fails
Each imported tool is named `slug__tool`, capped at 64 characters total, and Apollo's longest tool name is 59 characters. That leaves room for a slug of at most 3 characters plus the double underscore, so the panel's prefilled slug (`apollo`, 6 characters) fails to import. Use a short slug such as `ap` instead.

### Connect Apollo in Agen.co

1. In the Agen.co portal, go to **Connectors** → **My connectors** and click **Add connector**.
2. In the **Select connector** drawer, search for `Apollo` and select it. The **Add Apollo** panel opens.
3. Fill in the field:
| Field | Required | Description |
|  --- | --- | --- |
| **Instance Slug** | Yes | Prefixes each imported tool as `slug__tool`, so several instances of the connector can coexist. Prefilled with `apollo`, but that's too long to fit Apollo's longest tool name under the 64-character cap — replace it with something 3 characters or shorter, such as `ap`. Use lowercase kebab-case. You can change it later from the connector's settings. |
4. Click **Connect**. Apollo opens in a new tab, and the panel shows **Waiting for authorization — complete it in the opened tab…**
5. Sign in to Apollo if prompted, then approve the requested access.
6. Back in Agen.co, the panel switches to **Select the tools to import from Apollo.** Every tool is toggled on; turn off any you don't want to import, then click **Add**.


The connector is created and its tools imported only when you click **Add**. If you close the panel before that, nothing is saved, even though the Apollo tab reported success.

### Authorize each user

Adding the connector doesn't authorize anyone's tool calls yet. The first time each user's agent calls an Apollo tool, the call returns an authorization link instead of a result. The user opens the link and approves the same way. After that, the user's tool calls run with their own Apollo account and permissions — including that account's own credit balance and whatever Apollo plan and workspace role it has.

Once connected, Apollo appears under **My connectors** with 98 tools spanning:

| Area | What it covers |
|  --- | --- |
| **Search and enrichment** | Searching and enriching people and companies, one at a time or in bulk, and reading a company's job postings — all credit-consuming |
| **Contacts and accounts** | Creating, updating, and searching contacts and accounts, including bulk contact and account creation |
| **Sequences and outreach** | Searching, creating, updating, and approving email sequences; adding or removing contacts from a sequence; searching, creating, and sending sequence messages; and reading campaign activity and email send status |
| **Deals** | Reading and creating opportunities |
| **Tasks** | Creating and listing tasks |
| **Calls** | Creating, updating, and searching logged phone calls, and reading conversation-intelligence analysis of calls |
| **Custom objects and fields** | Reading and writing custom objects, and creating and listing custom fields |
| **Lists and tags** | Creating and updating lists, adding or removing entities, and listing tags |
| **Website visitors** | Reading tracked website visitors, and managing the visitor domain tracker |
| **Account and usage** | Reading the connected user's profile, listing workspace users, and reading API and credit usage stats |
| **Domains and email accounts** | Browsing or purchasing sending domains and email accounts, and checking domain authentication status |


Enabling the Apollo connector isn't enough on its own. Tool calls remain denied until you create a [policy](/agen-for-work/policies/overview) that grants access to the specific tools you want to expose.
