{ "from": "FROM", "to": "{{customer.phone}}", "message": "Thank you for registering." }
You will need
- Your tyntec API key from your tyntec account
- Sender ID or a business phone number registered with tyntec
- A testing phone number whitelisted in the Business Center
- A verified Customer.io account
Step One: Create a campaign
You will create a workflow of a message which Customer.io sends in response to user behavior. (In this case, to new opt-ins.).
1. Sign in to your Customer.io account.
2. Head over to the Campaigns tab.
3. Click Create Campaign.
4. Enter a campaign name and click Create Campaign.


6. Drag the Webhook block and drop it in the middle.
7. Select the dropped Webhook block.
8. Click Add Request. Set the method to POST, URL to “https://api.tyntec.com/messaging/v1/sms” and create a header with name apikey and with your tyntec API key as its value. Then set the body to the following JSON:




Now, you have created a new campaign that sends an SMS to every new customer.
Step Two: Create a broadcast
You will create a message sent to a large group of people at once. (In this case, an API triggered broadcast.).
1. Head over to the Broadcasts tab.
2. Click Create Broadcast.
3. Enter a broadcast name, select the Messages triggered via API type and click Create Broadcast.


5. Drag the Webhook block and drop it in the middle.
6. Select the dropped Webhook block.
7. Click Add Request. Set the method to POST, URL to “https://api.tyntec.com/messaging/v1/sms” and create a header with name apikey and with your tyntec API key as its value. Then set the body to the following JSON:
{ "from": "FROM", "to": "{{customer.phone}}", "message": "We have a new product for you!" }



Now, you have created a new broadcast that sends an SMS to all customers with a phone number.
Step Three: Try it out!
Nothing more is needed to reach your customers through SMS. Now you can test it!
1. Start with adding a new person. Head over to the People tab, click Add People and Add a Person. Fill in an id or email. Click Create New Attribute, name the new attribute phone and fill in your testing mobile phone number as the value. Click Save Changes.



Voila! Your campaigns and broadcasts can now be sent as SMS messages!
More?
People can be added to Customer.io using the REST API. You may want to create a new person when a new user sends a message to your business phone number for the first time. For that, you need to deploy a webhook that creates a new person using Customer.io’s /api/v1/customers/{identifier} endpoint. Then, you need to register your endpoint in the SMS channel in Conversations API so that it calls the endpoint whenever a user sends you an SMS.
If you want to keep using the SMS channel in Conversations API for SMS notifications, change the URL from https://api.tyntec.com/messaging/v1/sms to https://api.tyntec.com/conversations/v3/messages and set the body to the following JSON:
{ "from": "your business phone number", "to": "{{customer.phone}}", "channel": "sms", "content": { "contentType": "text", "text": "A simple text message" } }
Also, campaigns can be triggered in various ways. For example, they can be triggered by an event, such as a purchase. Events can be triggered using Customer.io’s /api/v1/customers/{identifier}/events endpoint.
