What it does
Send an SMS instantly by providing your phone number, message body, and API key to trigger a manual workflow that delivers the text via Textbelt and confirms whether it succeeded or failed.
Step by step
- Configure the manual trigger node to accept phone_number, message_text, and api_key as input parameters.
- Set up an HTTP request node with method POST targeting https://textbelt.com/text.
- Map the input variables to the JSON body fields 'phone', 'message', and 'key' in the HTTP request payload.
Where the LLM does the work
- Generate user-friendly error messages that interpret Textbelt's specific API response codes for end users.
- Draft validation logic descriptions for phone number formats if additional preprocessing is desired beyond basic input capture.
- Create documentation comments explaining the security implications of passing API keys through manual triggers.
Watch out for
The API returns plain text responses rather than JSON which requires parsing logic to extract success status accurately.
Phone numbers must include country codes without leading zeros so add a formatting rule to ensure valid E.164 format.

The agent brief
Everything your agent needs, including the gotchas. Copy it and go.
You are helping me build the following AI agent workflow. ## Goal Simple SMS Messaging System: Manually trigger a workflow to send an SMS via Textbelt by providing a phone number, message body, and API key. ## Specification - What it does: Send an SMS instantly by providing your phone number, message body, and API key to trigger a manual workflow that delivers the text via Textbelt and confirms whether it succeeded or failed. - Trigger: Run manually (Manual · on demand) - Autonomy: Fully hands-off - Expected setup effort: under an hour - Tools/services involved: - HTTP Request: Sending SMS via Textbelt API ## Known pitfalls, handle each one explicitly in your implementation 1. The API returns plain text responses rather than JSON which requires parsing logic to extract success status accurately. 2. Phone numbers must include country codes without leading zeros so add a formatting rule to ensure valid E.164 format. ## Reference implementation https://n8n.io/workflows/6228 (workflow template) Fetch and inspect this before building. If it matches my stack, adapt it; if not, rebuild the pattern with my tools. ## Process requirements 1. Before building: ask me which of the listed tools I actually use and what my platform is (n8n / Make / code / other). Do not assume. 2. Adapt the pattern to my answers; do not force the reference stack. 3. Address every pitfall above; tell me how you handled each. 4. Provide a test plan I can run before letting this touch real data. 5. Ask before any step that sends messages, modifies data, or spends money.

Want this running in your business?
This is what I do. I design and build AI agents like this one, and keep them running. If you want it set up for your team instead of doing it yourself, get in touch.
Who it's for
Built for founders and execs who need personal productivity handled without hiring for it.
Freelancers and consultants can run this per-client with no changes beyond the source data.
