Connect Claude & ChatGPT to Space Invoices / Apollo

Ask your AI to draft an invoice, check whether it has been paid, or send a customer a payment reminder in Space Invoices. It can create invoices, estimates and credit notes, record payments you have received, and download or email documents as PDF. Customers, items and tax rates are looked up for you, so you only describe what to bill.

Questions

What can the AI do in Space Invoices?

The AI can search and read invoices, estimates, credit notes, payments, customers, items, expenses and tax rates, and download documents as PDF. It can create and update invoices, estimates, customers and items, create credit notes, record and delete payments, void invoices, email documents and send payment reminders.

Does the AI see my Space Invoices credentials?

No. Your Space Invoices API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. Voiding an invoice cannot be undone, deleting a payment removes it from your records, and emailing documents or reminders reaches your customers, so these can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Space Invoices account.

Should I use an entity key or an account key?

An entity key (ek_...) is limited to one business, which is the simplest choice if you only have one. An account key (sk_...) controls several entities, and the AI can list them to pick the right business. Use a live key for real data, not a sandbox key.
