Prerequisites

  • An active Gravity SMS subscription
  • A connected RingCentral account — Connecting RingCentral
  • A Microsoft 365 or Power Automate plan that supports custom connectors

Setup

  1. Sign in to your Gravity SMS dashboard.
  2. Go to Integrations and activate the Power Automate integration. Copy the API key it generates.
  3. Confirm your RingCentral account is connected under RingCentral. If not, complete the OAuth connection first.
  4. In Power Automate, search for the Gravity SMS connector when adding a step. When you create a connection, paste the API key into the API Key field.
  5. Drop the Send SMS action (or When an SMS is received trigger) into your flow.

Example: send SMS when a row is added

  1. Trigger: When a new row is added (Excel, SharePoint, or Dataverse)
  2. Action: Send an SMS message from the Gravity SMS connector
  3. Map the row fields:
    • to — the row's phone field (must be E.164, e.g. +14155551234)
    • from — one of your RingCentral SMS-enabled numbers
    • body — your message text
  4. Save and test the flow.

Example: respond to inbound SMS

  1. Trigger: When an SMS is received from the Gravity SMS connector. Optionally filter by your sending number.
  2. Action: any downstream step — log to Excel, create a Planner task, post to Teams, or send another SMS in reply.
  3. Available fields on the trigger: from, to, body, messageId, timestamp.
Limits and constraints
  • Messages are 1–1600 characters.
  • Phone numbers must be E.164 (e.g. +14155551234).
  • The inbound trigger requires a connected RingCentral account in the Gravity SMS dashboard.
  • Standard API rate limits apply — see Rate Limits.
Consent (TCPA / similar) is your responsibility
Sending SMS to recipients who haven't given prior express consent is a regulatory violation in most jurisdictions. "Send SMS on every new row" patterns are a common way to violate this accidentally. Verify each recipient has opted in before your flow sends.
