HubSpot CRM API

Technical Preview

Overview

A client-mode connector for a curated eight-operation slice of the HubSpot CRM API: list/create/get/update contacts, list/get companies, list deals, and list owners. It is meant for CRM / service edge bridges, not the full HubSpot surface. BASE_ADDRESS defaults to https://api.hubapi.com (official OpenAPI host). https://api.hubspot.com also accepts CRM calls.

HubSpot CRM requires a private app access token or OAuth Bearer token. Unauthenticated calls return HTTP 401. The legacy api-catalog-public/v1/apis catalog was sunset (HTTP 404); specs now live at public/api/spec/v1/specs.

Basic Syntax

# Coreflux REST_API template — HubSpot (CRM v3)
# Generated from curated OpenAPI; credentials are placeholders only.
# Docs: https://docs.coreflux.org/latest/lot-language/routes/rest-api-routes
# Auth: HubSpot private-app access token (or OAuth) as Bearer {value.json.api_token}.
# Prefer Hub secrets / GET SECRET — never commit real tokens.
# BASE_ADDRESS: https://api.hubapi.com (official). https://api.hubspot.com also accepts CRM calls.

Auth

Private app or OAuth Bearer:

ADD "Accept" "application/json"
ADD "Authorization" "Bearer {value.json.api_token}"

string

required

HubSpot private app access token or OAuth access token. Prefer a Hub secret. Never commit the token.

string

Contact record ID. Required on Getcontact and Updatecontact.

string

Company record ID. Required on Getcompany.

High-level token flow (no secrets in the template):

Create a HubSpot private app with CRM scopes (contacts, companies, deals, owners) — or use an OAuth app.
Copy the private app access token (or obtain an OAuth access token).
Publish the token as api_token on the MQTT request payload (or inject from Hub secret upstream).

List contacts:

{"api_token": "YOUR_HUBSPOT_PRIVATE_APP_TOKEN"}

Get contact:

{"api_token": "YOUR_HUBSPOT_PRIVATE_APP_TOKEN", "contactId": "123"}

Create contact (connector body is {payload}; include CRM properties):

{"api_token": "YOUR_HUBSPOT_PRIVATE_APP_TOKEN", "properties": {"email": "ops@example.com", "firstname": "Plant", "lastname": "Ops"}}

Try it

Add the connector on your broker (BASE_ADDRESS already points at https://api.hubapi.com).
Publish token JSON to integrations/hubspot/request/Listcontacts.
Subscribe to integrations/hubspot/response/Listcontacts.
Contacts / companies: include contactId or companyId as needed.
