MessageMedia

Add MessageMedia to your product for your customers, and give your AI agents governed access to it.

Embed a MessageMedia integration so your customers send business SMS from their own account and their own numbers, so a message arrives as theirs rather than as yours. Every customer authorises their own account, which keeps volume, numbers and consent records with the business they belong to, and means a customer revoking access affects only their own connection. Sends are deduplicated per event, because a text sent twice is immediately visible to the person receiving it, and replies and delivery reports come back as events your product can act on. fastn owns the credentials, retries and API upkeep, and the same connection serves your AI agents.

In your product

Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.

Let each customer send SMS from their own MessageMedia account and numbers, so messages come from them rather than from you.

Send a message from a product event, deduplicated per event so a retry does not text someone twice.

Read replies and delivery reports so a response continues a workflow in your product instead of sitting in an inbox.

Keep sending scoped per tenant so volume, numbers and consent records stay with the customer they belong to.

For your AI agents

Governed, audited access for the agents you build, through the MCP server.

An agent sends a reminder or confirmation by SMS within scoped permissions, with each send attributed.

An agent reads an inbound reply and takes the next step, with the read audited.

An agent reports which messages failed to deliver for one customer and why.

Example prompt

Send this appointment reminder by SMS and tell me when the customer replies.

Set up MessageMedia in 4 steps

  1. 01Enable the MessageMedia connector in your fastn dashboard.
  2. 02Have each customer connect their own MessageMedia account and numbers.
  3. 03Map the message templates and product events that trigger a send, per customer.
  4. 04Call it from your product and expose the same connection to your agents through the MCP gateway.

Why teams use the MessageMedia integration

What you get by embedding it with fastn instead of building it yourself.

  • Ship a MessageMedia integration without building it. Your customers connect their own MessageMedia account inside your product and work their messages, conversations and participants there, with no per-customer code on your side.
  • Handle the part that actually costs time: anything sent is user-visible, so duplicates and misfires are immediately embarrassing. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a MessageMedia update is not your on-call problem.
  • One integration serves your product and your agents. The same governed MessageMedia connection powers in-product features and gives AI agents scoped, audited access, so you put the right message in front of the right team automatically without wiring it twice.

MessageMedia integration FAQ

How do I add a MessageMedia integration to my product?

Enable the MessageMedia connector in your fastn dashboard, then let each customer authenticate their own MessageMedia account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no MessageMedia client code in your app and no per-customer branch in your codebase. Setup is 4 steps.

Do my customers each connect their own MessageMedia account?

Yes. Every connection is scoped to the individual customer, so each authorises their own MessageMedia account and only ever sees their own messages, conversations and participants. 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 MessageMedia 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 sends a reminder or confirmation by SMS within scoped permissions, with each send attributed.

Who maintains the MessageMedia integration?

fastn does. When MessageMedia 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.

Does each customer connect their own MessageMedia account?

Yes. Every customer authorises their own MessageMedia account, so messages, meetings and notifications originate from their workspace under their permissions. You never proxy through a shared account, which also means a customer revoking access affects only their own connection.

How are duplicate notifications avoided?

Sends are deduplicated per event, so a retry after a network failure does not post the same message twice into a channel people are reading.

What can I build with the MessageMedia integration?

A common starting point: let each customer send SMS from their own MessageMedia account and numbers, so messages come from them rather than from you. 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 MessageMedia integration cost?

It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding MessageMedia does not change your per-connector cost. You can start free with 3 connected accounts.
