Send Text Message

Setup

Read your credentials from ~/.gooseworks/credentials.json:

export GOOSEWORKS_API_KEY=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json'))['api_key'])")
export GOOSEWORKS_API_BASE=$(python3 -c "import json;print(json.load(open('$HOME/.gooseworks/credentials.json')).get('api_base','https://api.gooseworks.ai'))")

If ~/.gooseworks/credentials.json does not exist, tell the user to run: npx gooseworks login

All endpoints use Bearer auth: -H "Authorization: Bearer $GOOSEWORKS_API_KEY"

Send SMS messages via the Textbelt API on Orthogonal.

Workflow

Step 1: Gather Info

Ask the user for:

  • Phone number (required) - US/Canada: 10-digit with area code. International: E.164 format (e.g., +44...)
  • Message (required) - Max 800 characters. No URLs allowed.

Step 2: Send the Message

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"textbelt","path":"/text"}'
  "phone": "<phone_number>",
  "message": "<message_text>"
}'

Step 3: Confirm Delivery

The response includes a textId. Use it to check delivery status:

curl -s -X POST $GOOSEWORKS_API_BASE/v1/proxy/orthogonal/run \
  -H "Authorization: Bearer $GOOSEWORKS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"api":"textbelt","path":"/status/{textId}"}'

This endpoint is free.

Response

Send Response (/text)

  • success (boolean) - true if message was queued
  • textId (string) - Message ID for delivery tracking (only on success)
  • quotaRemaining (integer) - Remaining SMS credits
  • error (string) - Error message (only on failure)

Status Response (/status/{textId})

  • status (string) - DELIVERED, SENDING, FAILED, or UNKNOWN

Constraints

  • Max 800 characters per message
  • No URLs in message text
  • Sender name is optional and not visible to the recipient in most countries

Optional Parameters

When sending, you can also include:

  • sender (string) - Business/org name for regulatory purposes
  • replyWebhookUrl (string) - US only: URL to receive reply webhooks
  • webhookData (string) - Extra data passed to webhook (max 100 chars)

Error Handling

  • success: false with error field describes the issue (e.g., invalid phone number, insufficient credits)
  • US/Canada numbers only work from US/Canada IP region
  • International numbers require E.164 format (e.g., +44...)
  • Messages containing URLs are rejected — use descriptions instead
  • Max 800 characters — longer messages are rejected, not truncated
