Prerequisites
Before diving into the world of Twilio Slack integration, you'll need a few things in place.
To get started, you'll need a Twilio account. If you're new to Twilio, create a free account to explore its features and limitations.
A Twilio Phone Number is also a must-have. You can purchase one by following the instructions provided by Twilio.

Setting Up the Integration
To set up the integration, you'll need a Slack team and channel where you want to receive SMS. You'll also need a Twilio account and number where you'll receive the SMS.
First, sign up for a Twilio account and number, which has a free trial plan. You can also set up a Slack team and channel, also with a free trial plan.
You'll need to configure Twilio to call a function when you receive an incoming SMS. This involves creating a new Twilio Function, copying some code into it, and saving it. You can name your function "Relay SMS to Slack" or anything you like.
To configure the function, go to the Twilio Functions Configure page and add an environment variable SLACK_WEBHOOK_PATH. Paste the link from your incoming webhook, stripping off everything before /services in the URL.
Here are the steps to set up the Twilio function:
- Go to the Twilio Functions Configure page and add an environment variable SLACK_WEBHOOK_PATH.
- Create a new Twilio Function and choose the “Blank” template.
- Copy the following into the function:
Save the function and go to the configuration of one of your incoming numbers. Under the “Messaging” section, configure Twilio to call your function when you receive an incoming SMS.
Now you should be able to send an SMS and receive it in Slack.
Integration Details
To integrate Twilio with Slack, you'll need to enable the Slack integration in your Twilio Console account. This allows you to send and receive messages from your Twilio phone numbers directly in Slack.
The integration process involves authenticating with Slack using an OAuth token, which is obtained by authorizing the Twilio application in your Slack workspace. This token is then used to connect your Twilio account to your Slack workspace.
You can configure the integration settings to control how messages are sent and received between Twilio and Slack. For example, you can choose to send incoming messages from your Twilio phone number to a specific Slack channel or user.
Once the integration is set up, you can use the Twilio Slack integration to send messages from your Twilio phone number to a Slack channel, and also receive incoming messages from a Slack channel in your Twilio account.
You can manage the integration settings, including the OAuth token and channel mappings, from within the Twilio Console.

Setting Up the SMS Bridge
To set up the SMS bridge, you'll need a few things. You'll need a Slack team and channel where you want to receive SMS messages.
A Slack team is essentially a workspace where you can communicate with your team members. You can create one if you don't already have it.
You'll also need a Twilio account and a Twilio phone number where you'll receive the SMS messages. Twilio is a cloud communication platform that allows you to make and receive phone calls and SMS messages programmatically.
Here are the specific requirements:
- A Slack team and channel on which you want to receive SMS
- A Twilio account and number where you’ll receive the SMS
Integration Templates
Integration Templates are a crucial part of setting up a seamless Twilio Slack integration.
You can use Twilio's pre-built templates to integrate your Twilio account with Slack, allowing you to send and receive messages, make calls, and more directly from Slack.
Twilio provides a range of templates for different use cases, such as customer support, sales, and marketing, to help you get started quickly.
For another approach, see: How to Use Twilio
The "Customer Support" template, for example, allows you to create a custom Slack channel for customer support tickets, where agents can view and respond to messages from customers.
With the "Sales" template, you can integrate your CRM system with Slack, enabling sales teams to view customer information and make calls directly from Slack.
Twilio's integration templates are easy to set up and customize, even for those without extensive technical expertise.
By using these templates, you can save time and effort in setting up your Twilio Slack integration, and focus on more important tasks.
SMS Automation
To automate your SMS workflow, you can create a Twilio Studio Flow. This involves creating a new flow, which is an individual workflow that handles a specific use case, such as posting an inbound SMS to a Slack feed.
To create a new Studio Flow, log into your Twilio account and navigate to the Studio Dashboard. Click the Create a Flow button to start creating your first Studio flow.

You'll see a blank Canvas with a widget already in place - the Trigger (Start) widget. This widget will kick off your Flow when the trigger you specify is fired, which in this case is an Incoming Message.
You can name your Flow anything you like, but for this tutorial, we're calling ours "SMS to Slack". Then, select a template, but for this tutorial, you'll want a blank Canvas, so select Start from scratch.
Here's a step-by-step guide to creating your Studio Flow:
- Log into your Twilio account and navigate to the Studio Dashboard.
- Click the Create a Flow button to create your first Studio flow.
- Name your Flow, such as "SMS to Slack".
- Select a template, choosing Start from scratch.
With your Flow set up, you're ready to connect it to a Twilio phone number. This will allow you to automate your SMS workflow and send messages to Slack automatically.
Status Updates
You can set your Slack status to automatically update with a text message from Twilio. This is especially helpful if you're out of the office or have a changing schedule.
To do this, you'll need to send an SMS message to your Twilio number, and then Zapier will update your Slack status with the message. You can set the status to any text and emoji you want.
Zapier checks for new data every 15 minutes on the Free plan, so you don't have to worry about it getting stuck.
Here are the steps to set up this integration:
- When an SMS is sent to your Twilio number, Zapier will trigger the update.
- Then, Zapier will set your Slack status to the given text and emoji.
Why and How
Twilio Slack integration can be a game-changer for businesses, allowing teams to streamline their communication and workflows.
By integrating Twilio with Slack, you can create custom channels for different projects, teams, or departments, making it easier to stay organized and focused.
This integration enables you to send and receive messages, as well as make voice and video calls, all within Slack.
How Integrations Work
Integrations allow different systems to communicate with each other seamlessly, making it possible to automate tasks and streamline workflows.
This is achieved through APIs, which provide a standardized interface for data exchange between systems. For example, a customer relationship management (CRM) system can integrate with an email marketing tool using an API.
By integrating these systems, businesses can reduce manual data entry and increase productivity. According to a study, companies that implement integrations see an average increase of 30% in productivity.
Integrations can also help reduce errors by automating tasks and ensuring data consistency across systems. This is especially important for businesses that rely on accurate data for decision-making.
The key to successful integrations is choosing the right integration method, such as API-based integration or data synchronization.

Why?

You might wonder why you'd want to set up an SMS-to-Slack bridge. It's actually quite useful when you have an app that uses SMS as a notification channel.
You can use it to test that SMS is being sent properly by the app without having to use physical phones. This is especially helpful for QA teams.
Some SaaS vendors only offer 2FA via SMS, but don't allow multiple logins to access the same billing account. This can lead to teams sharing passwords or disabling 2FA altogether.
By setting up an SMS-to-Slack bridge, you can use it as your 2FA number, which is a bit of a security risk, but can be a helpful solution in a pinch.
You might also want to set up an SMS-to-Slack bridge if a SaaS product or legacy system you're signed up for sends notifications via SMS, but isn't integrated with Slack yet.
