Connect
Slack
Slack connects through OAuth 2.0. You authorize Modiva from Slack's own consent screen and pick the workspace to connect — Modiva then sends, edits and deletes messages, browses channels and their history, looks up members and adds reactions through one unified API and MCP server. Slack workspace bot tokens don't expire, so once connected your workspace stays connected until you remove the app.
Before you start
- A Slack workspace.
- Permission to add an app to that workspace (or an admin who can approve it).
Step-by-step setup
- 1
Sign in to Modiva
Log in at modiva.ai and open the Dashboard. You need a Modiva account before you can connect any platform — creating one takes a minute and no credit card is required for the free tier.
The Modiva dashboard — your home for connections, posts and analytics. - 2
Open Connections → New connection
In the left sidebar choose Connections, then click New connection. You'll see the full catalogue of platforms grouped by category (Social, Ads and CRM).
The connection picker. Use the search box or category filter to find your platform. - 3
Select Slack
Click the Slack card. Modiva redirects you to Slack's official sign-in and permission screen — your password is entered on Slack, never on Modiva.
Click Connect on the Slack card to start the secure OAuth flow. - 4
Authorize Modiva on Slack
Review the permissions Modiva is requesting and approve them. If you manage more than one account, page or profile, pick the one you want Modiva to manage.
Slack's consent screen. Approve the requested scopes to continue. - 5
You're connected
Slack now sends you back to Modiva and the connection appears with a green Connected status. From here it's available to every MCP key and API call in your workspace.
A healthy connection shows a green dot and the connected account name.
Permissions Modiva requests
When you connect Slack, Modiva asks only for the access it needs to run the tools you use. You can revoke it any time from Slack or by disconnecting in Modiva.
- Read your workspace identity
- Send, edit and delete messages as the Modiva app
- Browse channels and read channel history
- Look up workspace members
- Add emoji reactions
Troubleshooting & FAQ
Where is my Slack password stored?
Nowhere. You sign in on the provider's own site and Modiva only receives a scoped access token, which is encrypted at rest with AES-256-GCM. Modiva never sees your password.
My connection says Expired or Error — what do I do?
Open Connections, find the platform and click Reconnect (or Refresh token). Providers periodically expire tokens or revoke them when you change your password; reconnecting re-runs the consent screen and restores access.
How do I disconnect?
Open Connections, click the Slack row and choose Disconnect. Modiva deletes the stored token immediately. You can also revoke Modiva from inside Slack's own app settings.
Which workspace gets connected?
The workspace you select on Slack's consent screen when you authorize. To connect another workspace, run the flow again and pick it, or add a second connection.
Can Modiva post to private channels?
Modiva can post and read in a channel once its app is a member of that channel. For public channels it can join automatically; for private channels invite the Modiva app to the channel first.
Do Slack tokens expire?
No. Slack issues a long-lived workspace bot token, so there's no background refresh — the connection stays healthy until you remove Modiva from the workspace's app settings.
