Authentication

All requests are authenticated with a bearer token. Pass your API key in the Authorization header. Keys are scoped per project and can be rotated at any time.

export RELAYWIRE_API_KEY="rw_live_…"

curl https://api.relaywire.io/v3/account \
  -H "Authorization: Bearer $RELAYWIRE_API_KEY"

Send a message

POST /v3/messages queues a message for delivery and returns a message id you can use to track status via webhook or polling.

  -H "Authorization: Bearer $RELAYWIRE_API_KEY" \
  -d to="+1 555 0142" \
  -d channel="sms" \
  -d body="Your verification code is 4827"

Request parameters:

Message status
