Cargo CLI — Connections

Connector and integration management: listing connectors, discovering available integrations, and managing authenticated connector instances.

See references/response-shapes.md for full JSON response structures. See references/troubleshooting.md for common errors and how to fix them. See references/examples/connectors.md for connector CRUD and discovery examples. See references/examples/integrations.md for listing available integrations and OAuth flows. For third-party connector rate limit handling and retry config in workflows, see cargo-orchestration/references/polling.md and cargo-orchestration/references/troubleshooting.md. Native integrations do not have rate limits.

Bootstrap

Already signed in (cargo-ai whoami returns a workspace)? Skip to the next section.

npm install -g @cargo-ai/cli            # no global install? prefix every command with `npx @cargo-ai/cli`
cargo-ai login --email [email protected]  # emailed code, no browser; creates the account on first use
                                        # alternatives: --oauth (browser) · --token <api-token> (CI)
cargo-ai whoami                         # confirm the active workspace before any write

Every command prints JSON to stdout; failures exit non-zero with {"errorMessage": "..."}. Anything that creates a run or a batch is async — pass --wait-until-finished or poll the matching get. When the full skill bundle is installed, ../cargo/references/prerequisites.md adds the CLI version pin, token scopes, and the admin-only surface.

Key concepts

Integration: The external service type (e.g. HubSpot, Clearbit, Salesforce). Integrations define what actions are available.

Connector: An authenticated instance of an integration. One integration can have multiple connectors (e.g. two different HubSpot accounts). Connectors are what you reference in workflow node graphs.

Discover resources first

Looking for an action? Search for it — don't browse the catalog. Two keyword searches cover the whole surface, and both beat paging integration list or reading a whole integration get payload:

cargo-ai orchestration action list <query>                # START HERE — connector + native + tools + agents.
                                                          # Returns a ready-to-run action object (connectorUuid
                                                          # resolved) and the action's credit costs.
cargo-ai connection action search <query> --credits-only  # connector catalog only, but filters by
                                                          # "is it paid", which `action list` cannot.

Reach for the catalog commands when you need the integration, not an action — its auth fields, its extractors, or the full input schema of an action you have already picked:

cargo-ai connection connector list                        # all authenticated connectors
cargo-ai connection integration list                      # all available integration types
cargo-ai connection integration list --search "hubspot"   # search by name
cargo-ai connection integration get <slug>                # one integration's actions + input schemas
cargo-ai connection native-integration get                # built-in Cargo actions only (NOT third-party)

Deprecated integrations are hidden from the catalog by default. integration list, action list and action search leave them out unless you pass --is-deprecated true; integration get <slug> always returns one, with isDeprecated: true and a display name ending in (deprecated). They cannot be connected any more. Existing connectors keep working, but never wire a new workflow to one. Two were deprecated in CLI 1.0.92, the self-referential cargo integration among them. Read the flag rather than keeping a list: check isDeprecated before proposing any integration you found by browsing instead of by action list.

Which action search?

Default to action list — it is the one that hands you something you can execute. Switch to action search for the question it alone answers: which paid actions match this? (--credits-only). Both rank an action-slug or name hit above an integration hit, above a description hit, and require all query terms to match.

integration get vs native-integration get

These two commands return different sets of actions and are not interchangeable:

CommandThird-party service actions (HubSpot, Salesforce, Clearbit, …)Built-in Cargo actions (HTTP, transforms, utilities)When to use
integration get <slug>✓✗You need actions for a specific third-party service — use this for HubSpot, Salesforce, Clearbit, etc.
native-integration get✗✓You need Cargo-native capabilities that don't belong to any specific third-party connector

Example: To find HubSpot-specific actions, use integration get hubspot — native-integration get will not return them.

Connectors

Connectors are authenticated connections to external services.

# List all connectors
cargo-ai connection connector list

# Create a connector: no flags beyond --integration-slug opens the hosted form and waits
cargo-ai connection connector create --integration-slug clearbit

# Non-interactive: --config (shape depends on the integration) plus --slug and --name
cargo-ai connection connector create \
  --integration-slug clearbit \
  --slug clearbit_production \
  --name "Clearbit - Production" \
  --config '<integration-specific JSON>'

# Update a connector
cargo-ai connection connector update --uuid <connector-uuid> --name "Clearbit - Staging"

# Throttle and cache a connector (on create or update)
cargo-ai connection connector update --uuid <connector-uuid> \
  --rate-limit '{"unit":"minute","max":100,"strategy":"spread"}' \
  --cache-ttl-milliseconds 86400000

# Remove a connector
cargo-ai connection connector remove <connector-uuid>

# Check if a connector slug is taken
cargo-ai connection connector exists-by-slug --slug clearbit_production

Note: --slug (unique identifier) and --name (display name) are required with --config, and rejected without it (the hosted form asks for them). For OAuth-based integrations, the authentication flow is completed separately via connection integration complete-oauth.

Rate limit and cache are per connector. --rate-limit takes {"unit": "second" | "minute" | "hour" | "day", "max": <n>, "strategy": "spread" | "burst"} — spread paces calls evenly, burst lets them through and then waits, and burst with "second" is rejected. Set it below the provider's own ceiling when one API key is shared across plays. --cache-ttl-milliseconds makes a workflow node with an identical computed config inside the TTL return the cached result instead of calling the provider — and bill 0 provider credits for it. It only takes effect on integrations whose actions are cache-compatible; elsewhere it is ignored. A day-long TTL on an enrichment connector is a free dedupe across overlapping batches.

Integrations

Integrations define the available services and their connector actions.

# List all available integrations
cargo-ai connection integration list

# Filter by category
cargo-ai connection integration list --category enrichment

# Search by name
cargo-ai connection integration list --search "hubspot"

# Find by exact slug(s)
cargo-ai connection integration list --slugs clearbit

# Only integrations that have actions (usable in workflow nodes)
cargo-ai connection integration list --has-actions true

# Only integrations that have extractors (can sync data into models)
cargo-ai connection integration list --has-extractors true

# Get built-in Cargo actions and extractors (NOT third-party connector actions)
cargo-ai connection native-integration get

Integration categories: engagement, marketing, sales, finance, analytics, freeform, success, support, enrichment, storage, custom.

Use integration get <slug> to discover all actions available for a specific third-party service (e.g. HubSpot, Salesforce). Use native-integration get only for built-in Cargo actions — it does not return HubSpot or other service-specific actions. Actions are referenced by actionSlug in workflow node graphs (see the cargo-orchestration skill's references/nodes.md).

Custom integrations

A custom integration is an integration you host: an HTTP server that speaks Cargo's integration protocol — GET /manifest, POST /actions/<slug>/execute, POST /extractors/<slug>/fetch (and /count), POST /autocompletes/<slug>, POST /dynamicSchemas/<slug> — registered with the workspace so its actions and extractors show up beside the catalog's. It runs either on your own server (external) or on a Cargo Hosting worker (worker; scaffold one with cargo-ai hosting worker init <dir> --template custom-integration).

cargo-ai connection custom-integration create --kind external --base-url https://integrations.example.com
cargo-ai connection custom-integration create --kind worker --worker-uuid <worker-uuid>
cargo-ai connection custom-integration list
cargo-ai connection custom-integration get <uuid>
cargo-ai connection custom-integration update --uuid <uuid> --base-url https://new.example.com   # or --worker-uuid; kind cannot change
cargo-ai connection custom-integration remove <uuid>

Registration assigns the integration a generated slug; create a connector against it with connector create --integration-slug <that slug> as for any other integration. An external base URL must be publicly reachable — private and loopback addresses are refused (unsafeOutboundUrl), so a local server needs a tunnel. worker fails with workerNotFound until the worker exists in this workspace.

Connector autocomplete — fetching available values for action fields

Some action fields don't accept freeform input — their allowed values must be fetched dynamically from the connector. When you inspect an action's config (via integration get <slug> or native-integration get), look at the uiSchema alongside the jsonSchema. If a field's uiSchema contains "ui:widget": "IntegrationAutocompleteWidget", the valid values for that field must be retrieved using connector autocomplete.

How to detect autocomplete fields

When an action's config looks like this:

{
  "jsonSchema": {
    "type": "object",
    "properties": {
      "objectType": { "type": "string", "description": "The object type" }
    }
  },
  "uiSchema": {
    "objectType": {
      "ui:widget": "IntegrationAutocompleteWidget",
      "ui:options": {
        "slug": "listObjects",
        "allowRefresh": true
      }
    }
  }
}

The objectType field requires autocomplete. The ui:options.slug ("listObjects") is the autocomplete slug you pass to connector autocomplete.

How to call connector autocomplete
cargo-ai connection connector autocomplete \
  --connector-uuid <connector-uuid> \
  --slug <autocomplete-slug> \
  --params '{}'
FlagRequiredDescription
--connector-uuidyesThe UUID of the connector to autocomplete against
--slugyesThe autocomplete slug from uiSchema[field]["ui:options"].slug
--paramsyesJSON object of parameters (use {} when none are needed)
--valuenoSearch string to filter results
--refreshnoBypass cache and fetch fresh results
Autocomplete with parameters

Some autocomplete fields depend on the value of another field. This is indicated by a params object in ui:options:

{
  "uiSchema": {
    "objectType": {
      "ui:widget": "IntegrationAutocompleteWidget",
      "ui:options": { "slug": "listObjects" }
    },
    "propertyName": {
      "ui:widget": "IntegrationAutocompleteWidget",
      "ui:options": {
        "slug": "listObjectProperties",
        "params": { "objectType": "$this.$parent.objectType" }
      }
    }
  }
}

Here, propertyName depends on the selected objectType. Replace the $this.$parent... expression with the actual value you chose:

# 1. First, get the list of object types
cargo-ai connection connector autocomplete \
  --connector-uuid <uuid> --slug listObjects --params '{}'

# 2. Then, get properties for the chosen object type
cargo-ai connection connector autocomplete \
  --connector-uuid <uuid> --slug listObjectProperties \
  --params '{"objectType": "contacts"}'
Response format
{
  "results": [
    { "label": "Contacts", "value": "contacts" },
    { "label": "Companies", "value": "companies" },
    { "label": "Deals", "value": "deals" }
  ]
}

Use the value field in your node config. The label is the human-readable display name. Results may also include optional description and parent fields.

Dynamic schemas — fields whose shape depends on another value

A field whose uiSchema carries "ui:widget": "DynamicSchemaWidget" has no fixed schema: its sub-fields come from the connector at configuration time (HubSpot's form-consent options, for one, depend on the chosen formId). Fetch the schema the same way as an autocomplete — the ui:options.slug and its params, with $this.$parent… references replaced by the values you chose:

cargo-ai connection connector get-dynamic-schema \
  --connector-uuid <uuid> --slug getConsentOptions --params '{"formId":"<form-id>"}'

--slug is the dynamic-schema slug from ui:options, not the action slug (the help said "action slug" before CLI 1.0.128). The response carries schema (JSON Schema for the field) and uiSchema; fill the field to match. Params that don't validate return an empty result (no schema) rather than an error, so an empty answer usually means a missing or misnamed param.

End-to-end example: configuring a HubSpot action
# 1. Find your HubSpot connector UUID
cargo-ai connection connector list --integration-slug hubspot

# 2. Get HubSpot actions and inspect their config + uiSchema
cargo-ai connection integration get hubspot
# → The "findRecords" action has objectType with autocomplete slug "listObjects"

# 3. Fetch available object types
cargo-ai connection connector autocomplete \
  --connector-uuid <hubspot-connector-uuid> \
  --slug listObjects --params '{}'
# → Returns: contacts, companies, deals, tickets, etc.

# 4. Fetch properties for the chosen object type
cargo-ai connection connector autocomplete \
  --connector-uuid <hubspot-connector-uuid> \
  --slug listObjectProperties \
  --params '{"objectType": "contacts"}'
# → Returns: email, firstname, lastname, phone, etc.

# 5. Use these values in your workflow node config

Using connector actions in workflows

Connector actions are used as nodes in workflow graphs. To use an action:

# 1. Find your connector UUID
cargo-ai connection connector list
# → Filter the output by integrationSlug to find the right connector

# 2. Discover the action — search first, and only then read its schema
cargo-ai orchestration action list <keywords> --integration-slug <integration-slug>
cargo-ai connection integration get <integration-slug>
# → actions are keyed by actionSlug, with config.schema (input) for each
# → many actions also carry output.schema — the JSON Schema of what the action
#   emits; use it to wire downstream nodes instead of guessing (absent on some actions)
# → Or use get-documentation for a plain text overview
# → Or use native-integration get for built-in Cargo actions (not third-party)

# 3. Reference the connector and action in a node graph
# See cargo-orchestration references/nodes.md for the full node syntax
Reading an action's input schema — and where the inputs go

An action's input fields live at actions.<slug>.config.schema in the integration get <slug> output (config.jsonSchema is the same schema decorated for the form UI). Read it before calling an action — don't guess field names.

# the required input fields for an action:
cargo-ai connection integration get linkedin \
  | jq '.integration.actions.connectProfile.config.schema'
# → required: linkedinProfileUrl, identityIds

Two footguns:

  • For a top-level action (action execute / execute-batch), the input values go in --data, NOT in the action's config. The fields described by config.schema are the --data payload; the action definition carries no config key at all. Misplacing them is no longer a loud failure: older backends rejected the call with A top-level action does not use action.config; pass the action's inputs via data instead., newer ones strip config on the way in, so its inputs never arrive — the call is refused before it runs on the first missing required field (invalidData), or runs on nothing when none is required, never with a message about config. If an action comes back empty or refused for no obvious reason, check that the inputs are in --data. A misspelled key in --data is refused before the run (Unknown field: <key>). (Inside a workflow node graph those same fields go in the node's config — see cargo-orchestration/references/nodes.md. The "--data, not config" rule is specific to action execute/execute-batch.)
  • Some inputs must be resolved first via autocomplete. If a field's uiSchema carries IntegrationAutocompleteWidget, fetch its values with connector autocomplete (above). Notably, LinkedIn engagement/extraction actions (connectProfile, visitProfile, extractEventAttendees, extractProfileViewers) require identityIds — the connected account that acts — resolved via the listIdentityIds autocomplete. A must match format "uuid" error means that identity is missing.

Example connector node (Clearbit company enrichment):

{
  "uuid": "node-uuid",
  "slug": "enrich",
  "kind": "connector",
  "integrationSlug": "clearbit",
  "actionSlug": "enrichCompany",
  "connectorUuid": "<clearbit-connector-uuid>",
  "config": {
    "domain": {
      "kind": "templateExpression",
      "expression": "{{nodes.start.domain}}",
      "instructTo": "none",
      "fromRecipe": false
    }
  },
  "childrenUuids": ["end-node-uuid"],
  "fallbackOnFailure": false,
  "position": { "x": 0, "y": 166 }
}
