Authentication

Authorization: Bearer <access_token>

  --secret-env WHATSAPP_CLOUD_ACCESS_TOKEN

uxc auth binding add \
  --id whatsapp-cloud \
  --host graph.facebook.com \

Core Workflow

1. Use the fixed link command by default:

   • command -v whatsapp-openapi-cli

   • If missing, create it:

     uxc link whatsapp-openapi-cli https://graph.facebook.com/v25.0 --schema-url https://raw.githubusercontent.com/holon-run/uxc/main/skills/whatsapp-openapi-skill/references/whatsapp-cloud.openapi.json

   • whatsapp-openapi-cli -h

2. Inspect operation schema first:

   • whatsapp-openapi-cli get:/{waba_id}/phone_numbers -h

   • whatsapp-openapi-cli get:/{phone_number_id}/whatsapp_business_profile -h

   • whatsapp-openapi-cli post:/{phone_number_id}/messages -h

3. Prefer read/setup validation before writes:

   • whatsapp-openapi-cli get:/{waba_id}/phone_numbers waba_id=123456789012345

   • whatsapp-openapi-cli get:/{phone_number_id} phone_number_id=123456789012345

   • whatsapp-openapi-cli get:/{phone_number_id}/whatsapp_business_profile phone_number_id=123456789012345

4. Execute with key/value or positional JSON:
   • key/value:

     whatsapp-openapi-cli get:/{phone_number_id} phone_number_id=123456789012345 fields=display_phone_number,verified_name

   • positional JSON:

     whatsapp-openapi-cli post:/{phone_number_id}/messages '{"phone_number_id":"123456789012345","messaging_product":"whatsapp","to":"15551234567","type":"text","text":{"body":"Hello from UXC"}}'

Operation Groups

Asset Discovery

• get:/{waba_id}/phone_numbers

• get:/{phone_number_id}

Business Profile

• get:/{phone_number_id}/whatsapp_business_profile

• post:/{phone_number_id}/whatsapp_business_profile

Messaging

• post:/{phone_number_id}/messages

Guardrails

• Keep automation on the JSON output envelope; do not use

  --text

  .
• Parse stable fields first:

  ok

  ,

  kind

  ,

  protocol

  ,

  data

  ,

  error

  .

• post:/{phone_number_id}/messages

  is a high-risk write. Require explicit user confirmation before execution.
• Message delivery is still constrained by WhatsApp conversation rules, template approval rules, recipient opt-in expectations, and account policy state. Auth success does not imply a send is allowed.
• This v1 skill does not manage media uploads. If you send

  image

  or

  document

  content, use already hosted URLs or existing asset references as allowed by the platform.
• Webhook subscription and verification are intentionally documented only. This skill does not configure a receiver runtime.
• Business profile update fields are partial. Only send the fields you intend to change.

• whatsapp-openapi-cli <operation> ...

  is equivalent to

  uxc https://graph.facebook.com/v25.0 --schema-url <whatsapp_openapi_schema> <operation> ...

  .
