API reference

Push signals into PilotPM from your own systems — agent-observed events and customer profile updates — and pull per-account product issues, feature requests, and summary counts into your CS tools. One auth header, an importable OpenAPI 3.1 spec. Only the endpoints on this page are part of the public, versioned API.

Versionv1 · current

OpenAPI 3.1 spec (JSON)https://app.pilotpm.ai

Authentication

Every request authenticates with a per-workspace agent token passed in the x-workspace-agent-token header. A workspace admin creates tokens under Settings → Agent tokens. The raw token (format wsk_…, 256 bits of entropy) is shown once at creation — only its SHA-256 hash is stored — and can be revoked instantly from the same screen.

One token = one workspace. The workspace is bound server-side from the token; request bodies never carry a workspace ID, so a leaked token can never reach another tenant.
Store the token in a secret manager (or your platform's encrypted env store) — never in source control or client-side code. Requests without a valid, unrevoked token get 401.
To rotate: generate a new token, switch your callers over, then revoke the old one. Multiple active tokens per workspace are supported, so rotation is zero-downtime.
Scopes. Tokens carry capabilities chosen at mint time: events:write (the write endpoints) and read (the GET /api/v1/accounts endpoints). The default mint has both; mint a read-only token for tools that should never write. Calling an endpoint without the required scope returns 403. Tokens created before scopes existed have full access.

Rate limits & caps

POST /api/events: 100 requests per 60-second sliding window per token. Excess requests return 429 with a Retry-After header (seconds) — honor it and retry.
POST /api/events bodies are capped at 64 KB (65,536 bytes); larger payloads are rejected with 413 before parsing.
Individual field caps (lengths, counts, ranges) are listed per endpoint below and enforced with 422 validation errors on /api/events.
GET /api/v1/accounts/…: 60 requests per 60-second sliding window per token (one budget shared across the three account endpoints), same 429 + Retry-After contract. List responses are capped at 50 rows, newest first.

POST

/api/v1/events

Ingest an event

Push a signal observed by an out-of-process agent into the workspace's event stream (themes, competitive intel, delivery risks, call briefs). The target workspace is bound from the token — a workspace_id in the body is ignored, as is any other unknown top-level field. Request bodies are capped at 65536 bytes (64 KB) and rejected with 413 before parsing. Rate limit: the shared per-token budget (60 requests/minute + 5,000/day across every endpoint in this spec) plus the per-workspace aggregate ceiling (2x); excess requests get the standard 429 (Retry-After + X-RateLimit-* headers). Requires the events:write scope. Also reachable at the legacy unversioned path /api/events (identical behavior).

Auth: x-workspace-agent-token header (required).

/api/v1/customers/upsert

Upsert a customer

Idempotent upsert of a customer record, keyed on (workspace, external_id). Call it when an end-user signs in, updates their profile, or changes plan; the resulting attributes render in the inbox side panel for every conversation linked to that customer. Attributes merge shallowly (new keys win, existing keys you don't send are kept). Attribute keys are lowercased; keys longer than 60 chars are dropped; PII-shaped keys (email, name, phone, address) are dropped from attributes — use the dedicated email / name fields instead. Values may be strings (truncated to 1000 chars), numbers, booleans, null, or arrays of primitives (capped at 20 items); nested objects are silently skipped. At most 50 attributes are stored per call. Requires the events:write scope. Also reachable at the legacy unversioned path /api/customers/upsert (identical behavior).

Auth: x-workspace-agent-token header (required).

Request body

Field	Type	Required	Constraints	Description
external_id	string	required	1–240 chars	Your system's stable ID for this user. Leading/trailing whitespace is trimmed; the trimmed value must be non-empty.
email	string	optional	—	Optional but recommended — enables inbound-email matching. Normalized to lowercase; stored encrypted.
name	string	optional	—	Optional display name. Stored encrypted.
attributes	object	optional	—	Flat bag of profile attributes (plan tier, platform, country, renewal risk, …). See the merge and sanitization rules in the endpoint description.

GET

/api/v1/accounts/{hubspotCompanyId}/issues

List an account's product issues

The account's product ISSUES: conversations whose latest inbound message the classifier tagged bug_report (the taxonomy's explicit defect bucket — crashes, errors, wrong results). Support/ops categories (billing, login, activation) are deliberately excluded. Accounts are keyed by HubSpot company id — the same key ChurnZero uses as Account External ID. Workspace is bound from the token; a company id belonging to another tenant returns 404 here. Spam and merged-duplicate conversations are excluded. Newest first, capped at 50 rows. Requires the read scope. Rate limit: the shared per-token budget (60 requests/minute + 5,000/day across every endpoint in this spec) plus the per-workspace aggregate ceiling (2x).

Auth: x-workspace-agent-token header (required).

Parameters

Name	In	Required	Constraints	Description
hubspotCompanyId	path	required	1–64 chars	The account's HubSpot company id — the same value external CS tools (e.g. ChurnZero) use as the Account External ID. Up to 64 chars of [A-Za-z0-9_-]; anything else returns 400 invalid_company_id.
status	query	optional	open \| all; default "open"	open (default) = conversations not yet resolved/closed (status open, awaiting_customer, or snoozed). all = include resolved and closed too. Unrecognized values fall back to open.

GET

/api/v1/accounts/{hubspotCompanyId}/requests

List an account's feature requests

The account's feature REQUESTS: conversations whose latest inbound message the classifier tagged feature_or_product. Caveat: that category also covers general product / how-it-works questions (the taxonomy doesn't split them), so treat these as an upper bound on true feature asks. Same keying, auth, exclusions, ordering, cap, status filter, and rate limit as the issues endpoint.

Auth: x-workspace-agent-token header (required).

GET

/api/v1/accounts/{hubspotCompanyId}/summary

Get an account's counts-only summary

Counts-only rollup for the account, computed in one query: open/total product issues (bug_report), open/total feature requests (feature_or_product), open conversations of any category, and the timestamp of the last message in either direction (last_contact_at). Open = status open, awaiting_customer, or snoozed. Spam and merged-duplicate conversations are excluded from every count. Also carries the org-level usage trio (licenses_purchased, learners_registered, org_utilization_pct) from ELSA's warehouse account mapping — null until the account is mapped. Same keying, auth, and rate limit as the list endpoints.

Auth: x-workspace-agent-token header (required).

GET

/api/v1/accounts/{hubspotCompanyId}/tickets

List an account's unified tickets (3 buckets)

The account's UNIFIED tickets across the three CSM-facing buckets: open_issue (product defects — bug_report), feature_ask (feature / how-it-works asks — feature_or_product), and learner_support (the account's day-to-day support: billing, cancellation, login, activation, other). Bucket = the latest inbound message's classifier tag. Accounts are keyed by HubSpot company id; workspace is bound from the token. Spam + merged-duplicate conversations are excluded. Per-row priority is DERIVED (SLA breach / VIP), not a first-class field. Newest first; keyset-paginated via next_cursor. Requires the read scope. Rate limit: 60 requests per 60-second sliding window per token (shared across the account endpoints).

Auth: x-workspace-agent-token header (required).

GET

/api/v1/accounts/{hubspotCompanyId}/tickets/{conversationId}

Get one ticket's detail + activity timeline

One ticket's detail: the list-row fields plus a PII-scrubbed first-inbound description_excerpt, the improvement-engine change_class (bugfix|feature|null — optional sharpening for feature asks), and an activity timeline (created / status changes / assignment / escalation / resolution) built from the conversation's audit log. Workspace- AND account-scoped: a ticket outside this account/workspace (or spam/merged) returns 404 unknown_ticket. Requires the read scope; same rate limit as the list.

Auth: x-workspace-agent-token header (required).

Parameters

Name	In	Required	Constraints	Description
hubspotCompanyId	path	required	1–64 chars	The account's HubSpot company id — the same value external CS tools (e.g. ChurnZero) use as the Account External ID. Up to 64 chars of [A-Za-z0-9_-]; anything else returns 400 invalid_company_id.
conversationId	path	required	UUID	The PilotPM conversation (ticket) id — the `id` field from the tickets list. Must be a uuid (else 400 invalid_conversation_id). A ticket that isn't in this account/workspace (or is spam/merged) returns 404.

Versioning & changelog

The current version is v1 — the endpoints documented on this page. Additive changes (new optional fields, new endpoints) ship within v1 without notice. Breaking changes ship under a new version prefix with its own spec; when that happens, the previous version keeps working for 6 monthsfrom the new version's publication, and both specs stay downloadable from this page.

v12026-07-04
READ API + token scopes: new GET /api/v1/accounts/{hubspotCompanyId}/issues, /requests, and /summary endpoints for pulling an account's product issues, feature requests, and counts into external CS tools (accounts keyed by HubSpot company id). Agent tokens now carry scopes — events:write (the write endpoints) and read (the new GET endpoints); existing tokens keep full access, and read-only tokens can be minted from Settings → Agent tokens. The write endpoints' canonical paths are now POST /api/v1/events and POST /api/v1/customers/upsert; the unversioned paths remain supported as legacy aliases.
v12026-07-04
Initial publication: POST /api/events (agent event ingestion) and POST /api/customers/upsert (customer profile upsert), authenticated with per-workspace agent tokens.
