Automate WhatsApp

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

Core Workflows

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.

On 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
• Preserve 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: source/target/label (not from/to)

Full schema: references/graph-contract.md

Function Rules

async function handler(request, env) {
  const body = await request.json();
  // Use env.KV and env.DB as needed
  return new Response(JSON.stringify({ result: "ok" }));
}

• Use function declaration (no export, export default, or arrow functions)
• Return a Response object

Execution Context

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

Scripts Reference

Workflows

Graph

Triggers

Executions

Functions

App Integrations

Databases

OpenAPI

npm i  # install deps (once)
node scripts/openapi-explore.mjs --spec workflows search "variables"
node scripts/openapi-explore.mjs --spec workflows op getWorkflowVariables

Notes

• Prefer file paths over inline JSON (--definition-file, --code-file)
• action_id = 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

References

Read before editing graphs:

• graph-contract.md — schema, computed vs editable fields, lock_version
• node-types.md — node types and config shapes
• workflow-overview.md — execution flow and states

Other references:

• execution-context.md — context structure and variable substitution
• triggers.md — trigger types and setup
• app-integrations.md — app integration and variable_definitions
• functions-reference.md — function management
• functions-payloads.md — payload shapes
• databases-reference.md — database operations
