SIGNL4
Add SIGNL4 to your product for your customers, and give your AI agents governed access to it.
SIGNL4 exists because an email is not a page. It escalates an alert through push, text and voice until a person acknowledges it, records who took it, and keeps a duty schedule so the right individual is targeted rather than everybody at once. An embedded SIGNL4 integration raises and resolves alerts against a customer's own team, attaches the detail somebody needs in order to act, reads acknowledgements and annotations so your product knows a human has it, and reads or updates who is on duty. The care goes into noise, because every alert here interrupts a person: repeat signals should update one alert instead of building a queue of identical ones. fastn holds each team's key per tenant and follows the API.
In your product
Embedded for your customers. Per-tenant auth, no per-customer code, maintained by fastn.
Let each customer connect their own SIGNL4 team so a condition your product detects reaches whoever is on duty.
Raise an alert carrying the context needed to act, then resolve it automatically once the condition clears.
Read acknowledgements so your product can show that a human has picked something up rather than assuming it.
Read the duty schedule so your product knows who would be woken before it decides to wake them.
For your AI agents
Governed, audited access for the agents you build, through the MCP server.
An agent reports which alerts fired overnight, who acknowledged them and what is still open.
An agent annotates an alert with what it found while investigating, with the note attributed.
An agent checks who is on duty before escalating anything further.
Example prompt
Who is on duty for this team right now, and which alerts from last night were never acknowledged?
Set up SIGNL4 in 4 steps
- 01Enable the SIGNL4 connector in your fastn dashboard.
- 02Have each customer supply the key for their own SIGNL4 team so alerts reach their people.
- 03Decide which conditions raise an alert, which resolve one, and how repeat signals are grouped so nobody is paged twice.
- 04Call it from your product and expose the same connection to your agents through the MCP gateway.
Why teams use the SIGNL4 integration
What you get by embedding it with fastn instead of building it yourself.
- Ship a SIGNL4 integration without building it. Your customers connect their own SIGNL4 account inside your product and work their incidents, alerts and on-call schedules there, with no per-customer code on your side.
- Handle the part that actually costs time: alerting is latency-critical and noisy, so filtering and deduplication matter. fastn owns the auth, token refresh, rate limits, pagination and breaking-change fixes, so a SIGNL4 update is not your on-call problem.
- One integration serves your product and your agents. The same governed SIGNL4 connection powers in-product features and gives AI agents scoped, audited access, so you route operational signal to the people and systems that act on it without wiring it twice.

Azure Key VaultSIGNL4 integration FAQ
How do I add a SIGNL4 integration to my product?
Enable the SIGNL4 connector in your fastn dashboard, then let each customer authenticate their own SIGNL4 account. fastn handles the OAuth flow, token storage and refresh per tenant, so there is no SIGNL4 client code in your app and no per-customer branch in your codebase. Setup is 4 steps.
Do my customers each connect their own SIGNL4 account?
Yes. Every connection is scoped to the individual customer, so each authorises their own SIGNL4 account and only ever sees their own incidents, alerts and on-call schedules. 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 SIGNL4 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 reports which alerts fired overnight, who acknowledged them and what is still open.
Who maintains the SIGNL4 integration?
fastn does. When SIGNL4 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.
How fast does a SIGNL4 alert reach my product?
Alerts arrive through event triggers rather than polling, so your product reacts in near real time instead of on a schedule.
Can duplicate or flapping alerts be suppressed?
Yes. Events are deduplicated per incident, so a flapping check does not create a queue of identical records for your users to sift through.
What can I build with the SIGNL4 integration?
A common starting point: let each customer connect their own SIGNL4 team so a condition your product detects reaches whoever is on duty. 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 SIGNL4 integration cost?
It is included. Pricing is based on connected accounts, not on how many connectors you enable, so adding SIGNL4 does not change your per-connector cost. You can start free with 3 connected accounts.
