Custom app connections are available on the Team plan. See White-label Connections for the overview.
What You Need
Create the app and generate the token
The Meta setup (app, system user, assigned assets, token) is the same for every Meta channel and lives on one page, including the optional permissions per channel.
Connect to Markifact
1
Open the Custom App tab
Go to the Connections page, click Connect on Instagram, and select the Custom App (White-label) tab.
2
Name the connection
Enter a Connection Name (for example “Acme Agency Instagram”). This is how the connection appears in nodes, agents, and MCP.
3
Paste the access token
Paste the Access Token generated for your system user.
4
Verify & Connect
Markifact makes one Graph API call that reads the token owner and the Pages it can reach, looking for one with a linked Instagram professional account. Nothing is saved unless that call succeeds.
Rotating or Replacing the Token
Add the connection again with the same connection name and the new token. Markifact replaces the stored token in place, so workflows and agents bound to the connection keep working.Troubleshooting
None of the Pages has a linked Instagram professional account
None of the Pages has a linked Instagram professional account
Instagram professional accounts are reached through the Facebook Page they are linked to. Link the Instagram account to a Page in Instagram settings, assign that Page (and the Instagram account) to the system user in Business Manager, then generate a new token.
