Attribute tokens are ready to use as condition selection paths (e.g. attributes.plan, computed.ltv). NOTE: these `attributes.*` tokens are ONLY for DECISION/CASE conditions — SEND_MESSAGE template bindings use a different syntax (`person.`); call journeys_message_variables for those. Also describes the cdp_predicate DECISION condition term shape: which `op` values are legal per attribute `type` (operatorsByType), and which `value` shape each `op` expects (cdpPredicateValueShapes). ## OpenAPI ````yaml /api-reference/openapi.json get /api/v1/journeys/condition-catalog openapi: 3.1.0 info: title: Boom API version: 1.0.0 description: >- Boom's public REST API — one uniform surface over every platform capability. CDP: upsert people and custom objects, define object and relationship types, link and unlink relationships, and record behavioral events — one record per request or up to 1000 per request via the `/batch` endpoints. Segments: read (list, read, membership) and full authoring — discover the filterable catalog, validate a filter, create and update segments, preview match counts, and trigger evaluation. Initiatives: create and configure outreach initiatives, link WhatsApp templates, drive the lifecycle (launch, cancel, archive), and read collected-data summaries. Participants: enroll people into an active initiative, track their status, read conversation transcripts, and stop outreach. Journeys: read-only access to always-on message flows and their metrics. WhatsApp templates: list your WhatsApp numbers and list, read, and create message templates. The same capabilities are exposed as MCP tools with identical schemas. servers: - url: https://www.useboom.ai description: Production - url: https://dev.useboom.ai description: Development (sandbox — use a development organization API key) security: - bearerAuth: [] paths: /api/v1/journeys/condition-catalog: get: tags: - Journeys summary: Condition catalog description: >- List the person attributes and computed attributes available for DECISION and CASE CONDITIONS, plus the custom object types.

A CLOSED set — any other key under `engagement.conversation.` is refused at publish, because a blank resolve there would read as 0 and open a gate that should be shut. Not available to CASE. This list is the DECISION view only: the same root also carries `id` and `inboxUrl`, which resolve in an HTTP_REQUEST node and are refused in a condition (nothing compares usefully against an id, and a numeric op would coerce it to 0 and take the branch). operatorsByType: type: object propertyNames: type: string additionalProperties: type: array items: type: string description: >- Legal `op` values for a cdp_predicate condition term, keyed by its `type`. cdpPredicateValueShapes: type: string description: >- Explains a cdp_predicate term's fields and the value shape each `op` expects. required: - person - computed - objectTypes - conversation - operatorsByType - cdpPredicateValueShapes additionalProperties: false '400': description: Validation failed or the request cannot proceed. content: application/json: schema: type: object properties: error: type: object properties: code: type: string description: Stable machine-readable error code (snake_case). message: type: string required: - code - message required: - error '401': description: Missing, malformed, or revoked API key. content: application/json: schema: type: object properties: error: type: object properties: code: type: string description: Stable machine-readable error code (snake_case). message: type: string required: - code - message required: - error '404': description: The resource does not exist in this organization. content: application/json: schema: type: object properties: error: type: object properties: code: type: string description: Stable machine-readable error code (snake_case). message: type: string required: - code - message required: - error '409': description: >- Conflicts with the current state (duplicates, wrong lifecycle state). content: application/json: schema: type: object properties: error: type: object properties: code: type: string description: Stable machine-readable error code (snake_case). message: type: string required: - code - message required: - error '422': description: The request is well-formed but semantically invalid. content: application/json: schema: type: object properties: error: type: object properties: code: type: string description: Stable machine-readable error code (snake_case). message: type: string required: - code - message required: - error '429': description: Rate limit exceeded — retry after `Retry-After`. content: application/json: schema: type: object properties: error: type: object properties: code: type: string description: Stable machine-readable error code (snake_case). message: type: string required: - code - message required: - error '500': description: Internal server error. content: application/json: schema: type: object properties: error: type: object properties: code: type: string description: Stable machine-readable error code (snake_case). message: type: string required: - code - message required: - error '503': description: Transient error — retry with a narrower request. content: application/json: schema: type: object properties: error: type: object properties: code: type: string description: Stable machine-readable error code (snake_case). message: type: string required: - code - message required: - error components: securitySchemes: bearerAuth: type: http scheme: bearer description: 'Organization API key, sent as `Authorization: Bearer boom_org_...`.' ```` This documentation is built and hosted on [Mintlify](https://mintlify.com), a developer documentation platform.
