  • Updated

If you're using Microsoft Power Automate (formerly Microsoft Flows) in your business, you may like to add SMS as an action to your workflows.

The very first time you add the SMS action to a flow, you'll be asked to provide API credentials for your messaging provider. To create a new API key and secret, just follow the steps in this article and save your API key and secret somewhere safe until you're prompted to input the API credentials.

Follow this article for step by step instruction on how to connect to the Sinch messaging provider.

 

Adding the SMS Action to a Workflow

1. Open Power Automate and go to My Flows, then you can either create a New Flow, or you can click on an existing workflow name and click to Edit.

3. Type in "Sinch" in the search box and you will then see the Sinch connector listed as a premium connector. Click on the Send Text Message (SMS) action. 

 

4. Next, in the message configurator, select a Sender Id from the dropdown which will have synced across from your Sinch account. This will display as the FROM address on the mobile handset. Then enter the details of your message in the Destination Number and Message fields:

 

6. When you've finished configuring your workflow just click Save and you're done, and remember to test out your flow to make sure the SMS is sent and everything is set up properly.

 

Things to Remember

  • Make sure when you enter the recipient's phone number that there's no spaces in the number (e.g. like this: +6140011122, not like this: +61400 111 222), because the system identifies a space as separating different phone numbers for different recipients.
  • You can send bulk SMS through SMS for Power Automate by adding a space, comma or period followed by the next person’s mobile number.
  • You can send messages internationally, as long as your messaging provider allows for this. You’ll need to use E.164 international format for the number, eg. +61400111222.
  • Message credits used depend on the content and characters per recipient. The following article has more details: Understanding Character Limits
