Try asking

“Any new SMS replies today?”
The AI lists inbound replies newest first, with the sender's number and the message text.
“Text 0412 345 678: your order is ready for pickup.”
It picks a sender from your allowed numbers and sender IDs and sends the SMS. This sends a real message and uses credit.
“How did yesterday's campaign perform?”
It finds the campaign and reads its delivery and click summary.

List and search contacts, create and rename contact lists, unsubscribe or delete numbers, and manage auto-reply keywords.

It reads the two-way message thread with that number.

Questions

What can the AI do in SMS Fusion?

The AI can read your inbox, conversations, sent messages, delivery reports, campaigns and their results, activity totals, contacts, contact lists, keywords, sender IDs and credit balance, and check a phone number. It can send SMS, MMS and campaigns to a list, cancel scheduled messages and campaigns, and manage contact lists, contacts and auto-reply keywords.

Does the AI see my SMS Fusion credentials?

No. Your SMS Fusion 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 with reading replies and reports. Sending SMS, MMS and campaigns reaches real people and uses credit, and deleting a contact is permanent. These actions can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and 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 SMS Fusion account. Messages the AI sends use your SMS Fusion credit.

Why do I need to change the key's IP allow-list?

SMS Fusion locks a new API key to the IP address you created it from. HeyMyApps calls SMS Fusion from its own server, so requests would be refused. Edit the key on the API page in the admin panel and empty the IP allow-list, or add HeyMyApps' server address.
