Getting Started

This integration creates a workflow with a Slack trigger and Twilio action. When you configure and deploy the workflow, it will run on Pipedream's servers 24x7 for free.

  1. Select this integration
  2. Configure the New Message In Channels trigger
    1. Connect your Slack account
    2. Optional- Select one or more Channels
    3. Configure slackApphook
    4. Configure Ignore myself
    5. Configure Resolve names
    6. Configure Ignore bots
  3. Configure the Download Recording Media action
    1. Connect your Twilio account
    2. Select a Recording ID
    3. Select a Format
    4. Configure File Path
  4. Deploy the workflow
  5. Send a test event to validate your setup
  6. Turn on the trigger


This integration uses pre-built, open source components from Pipedream's GitHub repo. These components are developed by Pipedream and the community, and verified and maintained by Pipedream.

To contribute an update to an existing component or create a new component, create a PR on GitHub. If you're new to Pipedream component development, you can start with quickstarts for trigger span and action development, and then review the component API reference.

Trigger Authentication

Slack uses OAuth authentication. When you connect your Slack account, Pipedream will open a popup window where you can sign into Slack and grant Pipedream permission to connect to your account. Pipedream securely stores and automatically refreshes the OAuth tokens so you can easily authenticate any Slack API.

Pipedream requests the following authorization scopes when you connect your account:

Action Authentication

Twilio uses API keys for authentication. When you connect your Twilio account, Pipedream securely stores the keys so you can easily authenticate to Twilio APIs in both code and no-code steps.

In Twilio, create an API key. There are two types of keys: Master and Standard. You'll need a Master key to interact with certain API endpoints, like /Accounts. If you don't need to interact with those endpoints, you can use a Standard key.

Once created, you'll receive an Sid and Secret here that you should enter in the corresponding fields below.

Then, in your Twilio Dashboard, you'll see your Account SID listed near the top. This is required for certain API operations. Enter that in the AccountSid field below.
