Automate WhatsApp

When to use

Use this skill to build and run WhatsApp automations: workflow CRUD, graph edits, triggers, executions, function management, app integrations, and D1 database operations.

Setup

Env vars:

  • KAPSO_API_BASE_URL
    (host only, no
    /platform/v1
    )
  • KAPSO_API_KEY

How to

Edit a workflow graph

  1. Fetch graph:
    node scripts/get-graph.js <workflow_id>
    (note the
    lock_version
    )
  2. Edit the JSON (see graph rules below)
  3. Validate:
    node scripts/validate-graph.js --definition-file <path>
  4. Update:
    node scripts/update-graph.js <workflow_id> --expected-lock-version <n> --definition-file <path>
  5. Re-fetch to confirm

For small edits, use

edit-graph.js
with
--old-file
and
--new-file
instead.

If you get a lock_version conflict: re-fetch, re-apply changes, retry with new lock_version.

Manage triggers

  1. List:
    node scripts/list-triggers.js <workflow_id>
  2. Create:
    node scripts/create-trigger.js <workflow_id> --trigger-type <type> --phone-number-id <id>
  3. Toggle:
    node scripts/update-trigger.js --trigger-id <id> --active true|false
  4. Delete:
    node scripts/delete-trigger.js --trigger-id <id>

For inbound_message triggers, first run

node scripts/list-whatsapp-phone-numbers.js
to get
phone_number_id
.

Debug executions

  1. List:
    node scripts/list-executions.js <workflow_id>
  2. Inspect:
    node scripts/get-execution.js <execution-id>
  3. Get value:
    node scripts/get-context-value.js <execution-id> --variable-path vars.foo
  4. Events:
    node scripts/list-execution-events.js <execution-id>

Create and deploy a function

  1. Write code with handler signature (see function rules below)
  2. Create:
    node scripts/create-function.js --name <name> --code-file <path>
  3. Deploy:
    node scripts/deploy-function.js --function-id <id>
  4. Verify:
    node scripts/get-function.js --function-id <id>

Set up agent node with app integrations

  1. Find model:
    node scripts/list-provider-models.js
  2. Find account:
    node scripts/list-accounts.js --app-slug <slug>
    (use
    pipedream_account_id
    )
  3. Find action:
    node scripts/search-actions.js --query <word> --app-slug <slug>
    (action_id = key)
  4. Create integration:
    node scripts/create-integration.js --action-id <id> --app-slug <slug> --account-id <id> --configured-props <json>
  5. Add tools to agent node via
    flow_agent_app_integration_tools

Database CRUD

  1. List tables:
    node scripts/list-tables.js
  2. Query:
    node scripts/query-rows.js --table <name> --filters <json>
  3. Create/update/delete with row scripts

Graph rules

  • Exactly one start node with
    id
    =
    start
  • Never change existing node IDs
  • Use
    {node_type}_{timestamp_ms}
    for new node IDs
  • Non-decide nodes have 0 or 1 outgoing
    next
    edge
  • Decide edge labels must match
    conditions[].label
  • Edge keys are
    source
    /
    target
    /
    label
    (not
    from
    /
    to
    )

For full schema details, see

references/graph-contract.md
.

Function rules

async function handler(request, env) {
  // Parse input
  const body = await request.json();
  // Use env.KV and env.DB as needed
  return new Response(JSON.stringify({ result: "ok" }));
}
  • Do NOT use
    export
    ,
    export default
    , or arrow functions
  • Return a
    Response
    object

Execution context

Always use this structure:

  • vars
    - user-defined variables
  • system
    - system variables
  • context
    - channel data
  • metadata
    - request metadata

Notes

  • Prefer file paths over inline JSON (
    --definition-file
    ,
    --code-file
    )
  • action_id
    is the same as
    key
    from
    search-actions
  • --account-id
    uses
    pipedream_account_id
    from
    list-accounts
  • Variable CRUD (
    variables-set.js
    ,
    variables-delete.js
    ) is blocked - Platform API doesn't support it
  • Raw SQL execution is not supported via Platform API
