Ask your first question:
How did we do today?
Claude should answer with today's and this month's orders, sent codes, and your credit balance. If you see numbers from your own account, you are connected. The first time Claude uses a tool it may ask permission to run it. Choose to allow it.
Claude lets you set, for each connector, how each group of tools runs. Open the Keysender connector in Claude (Customize, then Connectors, then Keysender) and look for its tool permissions. The menu wording may change over time. Claude shows these options:

Claude splits the tools into read-only tools and write/delete tools.

Set the read-only tools to Always allow or Needs approval, whichever you prefer. Set the write/delete tools to Needs approval. Claude sets them to Always allow by default. Keysender has these tools switched off for now, but set it once so Claude asks you when they arrive.

| Symptom | Action |
|---|---|
| There is no Add custom connector | Your plan or role may not allow it. On Team or Enterprise, ask your owner to add it. |
| The Keysender page says the return address is not allowed | Connect from Claude on claude.ai or the Claude desktop app, not from another tool. |
| You land back in Claude and are not connected | The sign-in was cancelled or took over 10 minutes. Select Connect again. |
| Claude says it cannot change anything | That is expected. Keysender launches as Read only, and making changes from the assistant is coming next. |
| A tool says a limit was reached | Wait a minute and try again, or try again later if you reached the daily limit. For very long lists, use the filters and export in your panel. If your work needs more, email [email protected] with your business case and the process you're trying to run, and we'll look at it. Ideas to improve the assistant are welcome there too. |
| Claude does not show codes or buyer details | For security, codes stay in Keysender. See them in your panel. Buyer details stay in your panel. Claude gives you a link to the page. |
| Keysender worked before and now asks you to connect again | A connection lasts up to 30 days, and ends after 14 days unused |
The Keysender sign-in page shows invalid_client |
The sign-in could not be matched to this connection. Remove the Keysender connector in Claude, add it again, and leave the client ID and secret empty. |
| Keysender is not in the Connectors list of your chat | The connector is off for this chat. Select +, then Connectors, and switch Keysender on. |
