Authorizations

​
Authorization
string
header
required

Bearer token in the Authorization header — for example, Authorization: Bearer trv_ak_your_api_key_here. Each key is bound to a specific user and organization.

Body

application/json
​
input
string
required

The incident description or question to investigate.

​
idempotency_key
string
required

Unique client-generated key for idempotent creation. Submitting the same key twice returns the original session (with 200 OK) rather than creating a new one. Use a value tied to the upstream event you are reacting to (e.g., a PagerDuty incident ID) so retries don't duplicate sessions.

Maximum string length: 128
​
title
string | null

A short label for the session. Auto-generated if omitted.

Maximum string length: 256
​
time
string<date-time> | null

ISO-8601 timestamp of when the incident occurred.

Response

Idempotency key matched an existing session; the existing session is returned unchanged.

​
id
string<uuid>
required

Unique session identifier.

Example:

"a1b2c3d4-e5f6-7890-abcd-ef1234567890"
