Fits in one SMS. 2 cents.

curl https://textrail.devflovv.com/api/v1/sms \
  -H "Authorization: Bearer $TEXTRAIL_API_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{
    "phoneNumber": "+14165550123",
    "message": "Your table for two is ready. Come on in."
  }'

Nothing is sent from this page. Run the request with your own key.

Verification codes are built in.

Ask for a code and TextRail makes one and texts it. Send back what your user typed and get a yes or a no. Codes have 6 digits, last 5 minutes and allow 5 tries.

Each code is one message at the normal price. How it works

You pay for what was sent.

Every message reports where it is, so your code never has to guess. If a message does not go out, it costs nothing.

  1. Queued

    Accepted. 2 cents is held from your balance.

  2. Sending

    On its way out.

  3. Sent

    Sent to the carrier. The 2 cents is charged.

  4. Delivered

    The carrier reported that it arrived.

Any other ending is free. The hold goes back to your balance.

  • Failed

    It did not go out.

  • Expired

    It could not go out in time.

  • Unknown

    We could not confirm it, so it is not resent.

One price, everywhere.

Top up your balance and each message spends 2 cents, whichever country it goes to.

Know what it isn’t.

A few things TextRail leaves out on purpose.

  • Outgoing only

    TextRail sends messages. It can’t receive replies.

  • One SMS per message

    Text over the limit is refused, never split into parts. Emoji and scripts outside the GSM alphabet allow 70 characters.

  • Prepaid

    There are no invoices. When your balance runs out, sending stops until you top up.

Your first text is one request away.
