Create App
Private apps authenticate with an API key sent as a Bearer token.

Click Copy in the Copy API key modal, then close it with X. Paste the value into PopMCP's API Key field.
App Marketplace
The finished app appears on the App Marketplace page under Built by you.
Connect in PopMCP
Open your workspace, choose Attentive in the marketplace, and fill in the connect dialog:
| Field | What to enter |
|---|---|
| API Keysecret | In Attentive go to ui.attentivemobile.com → Integrations → Custom apps (Manage custom apps), create a private app, and copy its API key. Sent as an Authorization: Bearer header, stored encrypted, used server-side only. The connection is locked to this key's Attentive company.Encrypted with AES-256-GCM on save and never shown again. |
PopMCP verifies the credential against Attentive immediately. On success the connection flips to Verified and its MCP tools are provisioned.
Verify it worked
PopMCP shows the Attentive connection as Connected and a first call returns your own company's subscriber or catalog data rather than a 401.
Troubleshooting
401 Unauthorized
Why: The key is wrong or truncated, or the custom app was deleted.
Fix: Create a fresh custom app and copy the new key from the modal. Old keys cannot be re-displayed.
403 on some tools but not others
Why: That API was left at No Access when the app was created.
Fix: Open the app under Integrations, Built by you, set the missing API to Write, and reconnect.
I closed the modal without copying the key
Why: Attentive shows the key exactly once and never again.
Fix: Delete the half-finished app, create a new one, and copy the key straight away.
Calls hit the wrong company's data
Why: The key is bound to the Attentive company that created the app.
Fix: Sign in to the correct company at ui.attentivemobile.com and create the app there.
No Integrations entry in the sidebar
Why: Your Attentive role does not include custom app management.
Fix: Ask an Attentive admin to create the app, or email api-tokens@attentivemobile.com.
