Buffer
Add Buffer to your product for your customers, and give your AI agents governed access to it.
Embed a Buffer integration so your customers can schedule and manage social posts across their own connected profiles from inside your product, with governed agent access to the same queue. Posts are user-visible, so sends are deduplicated per event and a retry after a network failure does not publish the same update twice. fastn handles each customer's OAuth and API upkeep, so onboarding another Buffer account is configuration rather than a release.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let customers connect their own Buffer account and list their connected social profiles inside your product.
Create and schedule posts to a customer's queue from your product, with deduplication on retry.
Read the pending queue and sent history so users see what is scheduled without switching tools.
Trigger your product when a post publishes or fails so follow-up steps run automatically.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent drafts and queues a post for human approval within governed permissions.
An agent reads the scheduled queue and flags gaps or clashes in the posting calendar.
An agent reacts to a failed post and reports why it did not publish.
Example prompt
Show posts scheduled for the next seven days by profile and flag any day with nothing queued.
Set up Buffer in 4 steps
- 01Open the Buffer connector from your fastn dashboard.
- 02Have each customer authenticate their own Buffer account with OAuth and select profiles.
- 03Map the post and profile fields your product uses, then enable actions and triggers.
- 04Call them from your product, or expose them to an agent through the MCP server.
Why teams use the Buffer integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a Buffer integration without building it. Your customers connect their own Buffer account inside your product and work their posts, pages and comments there, with no per-customer code on your side.
- Handle the part that actually costs time: anything published is public immediately, and each network gates access behind its own review process. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a Buffer update is not your on-call problem.
- One integration serves your product and your agents. The same governed Buffer connection powers in-product features and gives AI agents scoped, audited access, so you publish and listen from inside your product instead of a separate social tool without wiring it twice.

Zoho CRMBuffer integration FAQ
How do I add a Buffer integration to my product?
Enable the Buffer connector in your fastn dashboard, then let each customer authenticate their own Buffer account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no Buffer client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own Buffer account?
Yes. Every connection is scoped to the individual customer, so each authorises their own Buffer account and only ever sees their own posts, pages and comments. That per-tenant isolation is the point of an embedded integration: you support the long tail of customer setups without maintaining an integration per customer.
Can AI agents use this Buffer integration?
Yes. The same connection is exposed to your agents through the fastn MCP gateway, with permissions scoped per tenant and every call audited. An agent drafts and queues a post for human approval within governed permissions.
Who maintains the Buffer integration?
fastn does. When Buffer changes an endpoint, deprecates a field or alters its auth, the fix lands in the connector rather than in your backlog, and your customers' connections keep working.
Can my product publish to a customer's own Buffer account?
Yes. Each customer authorises their own account, so a post goes out as them, under their permissions, never from a shared account you own. That also means a customer revoking access affects only their own connection.
Can I read engagement back from Buffer?
Yes. Comments, reactions and reach come back scoped per tenant, so your product can act on them or show them in your own reporting without one customer's numbers mixing with another's.
What can I build with the Buffer integration?
A common starting point: connect their own Buffer account and list their connected social profiles inside your product. Teams also use it for the other use cases listed above, and expose it to agents for governed reads and writes.
How much does the Buffer integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding Buffer does not change your per-connector cost. You can start free with 3 connected accounts.
