Monitor usage-limit hits in Slack
Know the moment a customer bumps a plan limit — the clearest upsell signal there is — with their plan and account owner already attached.

the event
You emit usage.limit_reached with this shape. The TypeScript SDK keeps the call type-safe, and the event is stored whole — so every field below is available to the pipeline by name.
- customer_idstring
- metricstringseats | api-calls | storage
- limitnumber
- usednumber
- planstring
emit it
From your code with the TypeScript SDK — or any language over the REST endpoint and signed webhook ingress.
import { ingest } from "@ingestlayer/sdk";
await ingest("usage.limit_reached", {
customer_id: account.id,
metric: "api-calls",
limit: account.plan.apiLimit,
used: account.usage.apiCalls,
plan: account.plan.name,
}, {
idempotencyKey: `${account.id}:api-calls:${period}`,
});route it to Slack
Post to any channel in your workspace. Connect once with OAuth, pick the channel per pipeline.
- 01
connect your workspace
Authorize the ingestlayer Slack app over OAuth from the destinations page. We hold only a channel-scoped bot token, in-region, in the same KMS as your other credentials.
- 02
pick a channel
Choose any public channel, or invite the bot to a private one. The channel is set per pipeline, so different events can land in different places.
- 03
map the message
Reference event fields with $event.* in the message template. The default renders a titled block with the event name and its key fields.

notes
- Slack rate-limits to roughly one message per second per channel; bursts are queued and retried, never dropped.
- The bot must be a member of a private channel before it can post there — invite it explicitly.
- Block Kit caps a message at 50 blocks and 3000 characters per text field; oversized events are truncated with a link to the full payload.
questions
- How do I avoid firing this every request?
- Send it once per period with a period-scoped idempotencyKey, so a customer over the line all month is one alert, not thousands.
- Can it route straight to the account owner?
- enrich.entity attaches the CSM, so the upsell nudge reaches the person who owns the relationship.
- Can I treat hard and soft limits differently?
- Branch on the metric and the used/limit ratio to separate a gentle nudge from a service-blocking limit.
