Mittr integrates in two directions: inbound (receive webhooks from third-party services) and outbound (send notifications to platforms like Slack, Discord, and Email).
Inbound webhooks let you receive events from external services. Mittr verifies the source signature automatically using platform presets. You just provide your signing secret.
# Create an inbound endpoint for GitHub
curl -X POST https://app.mittr.io/api/v1/inbound-endpoints \
-H " X-API-Key: mtr_your_key " \
-H " Content-Type: application/json " \
"name": "GitHub Webhooks",
"pathSuffix": "github-prod",
"sourceConfig": { "secret": "your-github-webhook-secret" }
See the Inbound Webhooks guide for full setup instructions.
Organized by category. Each platform has a pre-configured verification preset, so Mittr knows the correct header name, algorithm, and signature format.

Returns every preset with its verification mode, header name, and required credential fields.
For platforms not in the preset list, use the generic source with manual configuration:
curl -X POST https://app.mittr.io/api/v1/inbound-endpoints \
-H " X-API-Key: mtr_your_key " \
-H " Content-Type: application/json " \
"name": "Custom Platform",
"pathSuffix": "custom-prod",
"headerName": "X-Custom-Signature",
"secret": "your-signing-secret"
Connectors send formatted notifications to external platforms when events are delivered or when alert rules fire.
