Retarus SMS4A

Retarus SMS4A

Overview

Use this skill for operational work with the Retarus SMS for Applications API: prepare or validate SMS job payloads, send jobs, and fetch per-recipient status for a jobId.

Prefer the helper script in scripts/sms4a_api.py instead of hand-writing HTTP calls. It already handles Basic Auth, simple payload construction, full-payload file input, datacenter selection, and the eu status fallback across de2 and de1.

Quick Start

1. Resolve credentials from the secret store into one of these supported inputs:
   • RETARUS_SMS4A_USERNAME and RETARUS_SMS4A_PASSWORD
   • RETARUS_SMS4A_SECRET_FILE pointing to a JSON or .env-style file with username and password
   • The default local secret file path ~/.openclaw/secrets/retarus-sms4a.env or ~/.openclaw/secrets/retarus-sms4a.json
   • Explicit --username and --password flags only for local testing
2. Send a simple SMS job:

python3 scripts/sms4a_api.py send \
  --datacenter eu \
  --text "Your access code is 123456" \
  --recipient +4917600000000 \
  --status-requested

1. Check recipient status for a job:

python3 scripts/sms4a_api.py status --job-id J.20221116-102407.583-0lajfsfmoXIZJO93PQ

Datacenter Rules

• Use eu as the default send endpoint unless the user explicitly wants de1 or de2.
• Do not rely on the eu hostname for status lookups. The eu endpoint is DNS-balanced across de1 and de2, so a status lookup must try both datacenters.
• The status command defaults to --datacenter auto, which tries de2 first and then de1.
• If the user explicitly prefers de1 or de2, still try both datacenters and use the chosen one only as the first lookup target.

Sending Workflow

• For common one-message jobs, pass --text and one or more --recipient values.
• For advanced jobs, pass --payload-file with a JSON body matching the OpenAPI JobRequest schema.
• Use --dry-run first if you want to validate payload assembly without sending anything.
• Return the created jobId and the datacenter that accepted the job.

Status Workflow

• Use status --job-id ... to query GET /sms?jobId=....
• Return the successful datacenter together with the recipient reports.
• If one datacenter returns 404 or 500, continue with the next datacenter.
• If both datacenters fail, report both attempts and their response codes.

Credential Handling

• Never hardcode credentials into the skill files.
• Prefer secret-store backed environment injection.
• Prefer the standard local secret path ~/.openclaw/secrets/retarus-sms4a.env for operator-managed credentials on an OpenClaw host.
• If a secret file is used, support either:
  • JSON: {"username":"...","password":"..."}
  • .env style:

RETARUS_SMS4A_USERNAME=...
RETARUS_SMS4A_PASSWORD=...

Reference

• Read references/api.md for the server aliases, supported helper-script options, and the subset of the OpenAPI schema this skill uses most often.
