Set up Apollo in your AI app
This guide is for Apollo users who want a simple setup path. Use your entity API key, connect the MCP endpoint, and start asking invoice questions in chat.
Quick setup
Create an entity API key in Apollo
Use the API key for the specific business you want the assistant to work with. In most Apollo setups, that single entity key is all you need.
Open your AI app
Use a desktop AI app like Claude Desktop, or another MCP-enabled tool where you can add a remote integration.
Add the Apollo MCP connection
Paste the MCP endpoint, add your bearer token, and save it as a new connection for Apollo invoice data.
Start asking real questions
Ask for overdue invoices, payment status, customer balances, or draft invoice help in plain language.

Recommended key
Entity API key for the Apollo business you want to use
Also supported
Account API keys work too. If you use one, pass the target entity so the assistant knows which business to work in.
Apollo note
With an entity API key, the assistant is already scoped to one business. That means most Apollo users do not need to think about selecting entities manually.
Using an account key instead?
That also works. It is more useful for teams managing multiple entities from one account, but it requires choosing the correct entity in the MCP client or prompt flow.
* Apollo does not expose your user data to AI systems by default. AI access is only available if you explicitly configure it. Apollo is GDPR-compliant.
Good first prompts
Need the technical version?
The Apollo setup above is enough for most end users. If your team needs client-specific MCP configuration details, advanced headers, or technical examples, use the full Space Invoices MCP guide.
That guide is written for developers and integration owners, while this page stays focused on the shortest practical setup for Apollo users.
Stop losing hours to invoice admin
Apollo gives small teams a faster way to invoice, follow up, and stay organized.
