Postscript integrates with Slack, allowing your customer service team to receive and respond to subscriber text messages using a dedicated Slack channel.

About Slack

Slack brings teams together and connects people to the information they need. With Slack, shops of all sizes can level up their communication and collaboration to get more work done.

How Our Slack Integration Benefits You

  • Receive and respond to subscriber text messages using a dedicated Slack channel.
  • Keep conversations threaded, allowing your team to focus on the conversation and work with the context they need.
  • Continue to use the Slack channel to communicate within your team. Only messages sent in subscriber's message thread will send to the subscriber.

Create a Postscript API Key

  1. Select your Shop Name in the side menu of your Postscript dashboard, then select API.
  2. Select Create Security Key Pair on the right side of the page, then confirm your action by selecting Yes.
  3. Select Show in the Private Key column to reveal your API key. Copy this key or write it down—you'll need to enter it in Slack later.

Got Questions? We've Got Answers

  • Can we send or receive MMS messages?
    • We are working to deliver the ability to send and receive MMS messages, but it is not currently available with this integration.
  • What happens if I react to a subscriber’s message in Slack?
    • Nothing happens over text. Team members can react to a subscriber’s message however they want and no message will be sent to the subscriber. Only text-based Slack messages (not reactions) entered in a message thread will be sent to the subscriber.
  • Can I see more information about the subscriber besides their phone number?
    • We are working to deliver the ability the see more information about a subscriber within Slack, but it is not currently available with this integration. Currently, only the number appears. You can copy the number into your search field in Postscript to access subscriber details.
  • What happens if I send a Slack message that is not threaded in the same channel where we set up the integration?
    • This Slack message would post to the channel as normal but would not send to any customers as a text. Only messages sent in a subscriber's message thread will send to the subscriber.
  • Can we send emojis?
    • Yes! We support sending all standard emojis from Slack to SMS and vice versa. Any custom emojis that you have in your Slack workspace, however, will not be translated on SMS since they are custom.
  • Can we connect more than one Postscript account to our Slack workspace?
    • Absolutely! You can connect as many Postscript accounts to a single Slack workspace as makes sense for your brand. Repeat the steps outlined above, but select a different Slack channel for the messages to display. You'll also need to enter a new Postscript API key. Last, don't forget to invite the Postscript bot to the new channel. We recommend you name the different Slack channels in a way that allows you to identify the different accounts.
