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

Scripts

Workflows

Graph

Triggers

Executions

Functions

App integrations

Databases

OpenAPI

Install deps (once):

npm i

Examples:

node scripts/​openapi-explore.mjs --spec workflows search "variables"
node scripts/​openapi-explore.mjs --spec workflows op getWorkflowVariables
node scripts/​openapi-explore.mjs --spec platform op queryDatabaseRows

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
