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

Preferred path:

• Kapso CLI installed and authenticated (kapso login)

• For workflow and function edits, use source-controlled projects with kapso link, kapso pull, kapso build, and kapso push

• For workflow code, use @kapso/workflows and export a Workflow instance from workflow.js or workflow.ts

Fallback path:

Env vars:

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

• KAPSO_API_KEY

How to

Edit workflows locally

Use this path first when the user is working in, or can create, a local repo.

npm install -g @kapso/cli

npm install --save-dev @kapso/workflows

kapso login

kapso link --project <project-id>

kapso pull

Edit workflows/<workflow-slug>/workflow.js or workflow.ts with @kapso/workflows:

import { START, Workflow } from "@kapso/workflows";

const workflow = new Workflow("inbound-support", {

  name: "Inbound Support",

  status: "draft",

});

workflow.addTrigger({

  type: "inbound_message",

  phoneNumberId: "<phone-number-id>",

});

workflow.addNode(START, {

  position: { x: 100, y: 100 },

});

workflow.addNode("reply", {

  type: "send_text",

  message: "Thanks for reaching out.",

});

workflow.addEdge(START, "reply");

export default workflow;

Build and push:

kapso build

kapso push --dry-run

kapso push workflow <workflow-slug>

Use kapso push to push every local function and workflow. See references/local-workflow-source.md for repo layout, source-file behavior, and JSON-only editing.

Discover phone numbers first

Preferred path:

• Check project state: kapso status

• List connected numbers: kapso whatsapp numbers list --output json

• Resolve a display number when needed: kapso whatsapp numbers resolve --phone-number "<display-number>" --output json

Fallback path:

• List number configs for triggers: node scripts/list-whatsapp-phone-numbers.js

Edit a workflow graph through API scripts

Prefer local source sync for workflow edits. Use these scripts as a fallback for debugging, direct graph inspection, or API-only environments.

• Fetch graph: node scripts/get-graph.js <workflow_id> (note the lock_version)

• Edit the JSON (see graph rules below)

• Validate: node scripts/validate-graph.js --definition-file <path>

• Update: node scripts/update-graph.js <workflow_id> --expected-lock-version <n> --definition-file <path>

• 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

• List: node scripts/list-triggers.js <workflow_id>

• Create: node scripts/create-trigger.js <workflow_id> --trigger-type <type> --phone-number-id <id>

• Toggle: node scripts/update-trigger.js --trigger-id <id> --active true|false

• Delete: node scripts/delete-trigger.js --trigger-id <id>

For inbound_message triggers, prefer kapso whatsapp numbers resolve --phone-number "<display-number>" --output json to get the exact phone_number_id. Fall back to node scripts/list-whatsapp-phone-numbers.js when the CLI is unavailable.

Debug executions

• List: node scripts/list-executions.js <workflow_id>

• Inspect: node scripts/get-execution.js <execution-id>

• Get value: node scripts/get-context-value.js <execution-id> --variable-path vars.foo

• Events: node scripts/list-execution-events.js <execution-id>

Create and deploy a function

• Write code with handler signature (see function rules below)

• Create: node scripts/create-function.js --name <name> --code-file <path> [--public-endpoint true]

• Deploy: node scripts/deploy-function.js --function-id <id>

• Verify: node scripts/get-function.js --function-id <id>

Use --public-endpoint true when the function should be callable without X-API-Key via the Kapso-hosted invoke URL. This is only supported for Cloudflare functions.

New functions default to invoke_response_mode=passthrough, which returns the function body directly on successful invoke. Legacy wrapped functions can be migrated later with update-function.js.

Set up agent node with app integrations

• Find model: node scripts/list-provider-models.js

• Find account: node scripts/list-accounts.js --app-slug <slug> (use pipedream_account_id)

• Find action: node scripts/search-actions.js --query <word> --app-slug <slug> (action_id = key)

• Create integration: node scripts/create-integration.js --action-id <id> --app-slug <slug> --account-id <id> --configured-props <json>

• Add tools to agent node via flow_agent_app_integration_tools

Set up agent node with remote sandbox repositories

Use this when the agent needs a remote ephemeral workspace to inspect or modify repository files during a workflow run.

• Read references/agent-remote-sandbox.md for the execution model and field rules

• Find model: node scripts/list-provider-models.js

• Copy assets/agent-remote-sandbox-github-repo-example.json as a starting point, or edit the agent node under data.config

• Set sandbox_enabled: true

• Set sandbox_network_mode to allow_all or allow_list

• If using allow_list, add extra outbound hosts in sandbox_allowed_outbound_hosts

• Add GitHub repositories to flow_agent_resources with:

• resource_type: "github_repository"

• repo_url

• branch

• pat

• Write the system prompt so it explicitly reads from /workspace/repos/<repo-slug> before making changes

• Validate and update the graph

Notes:

• Remote sandbox is beta and free during the beta

• sandbox_enabled controls whether the remote workspace and sandbox tools are available

• Repository resources stay configured even if sandbox access is turned off later

• v1 supports GitHub repositories only

• Use a repository root URL, not a GitHub file URL or tree/... URL

• Repositories are mounted into /workspace/repos/<repo-slug> inside the remote sandbox

• Use references/agent-remote-sandbox.md and references/node-types.md for the exact shape

Database CRUD

• List tables: node scripts/list-tables.js

• Query: node scripts/query-rows.js --table <name> --filters <json>

• 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
