Have you ever wished that your favorite apps could talk to each other?

Imagine this: the moment a new message appears in your Slack channel, whether that is an alert, an update, or any other post, it gets logged into a Google Sheet for easy tracking. No copying, no pasting, no coding-just automation.

That is exactly what Symplr Workflow Builder for Arazzo helps you do. Visual in nature, it allows for connecting APIs, cascading them, and orchestrating sophisticated workflows without actually writing even a line of code. Whether or not you are a developer, Symplr makes automation easy, intuitive, and powerful. Arazzo is the API orchestration engine inside Symplr. Users can chain multiple APIs together in a single automated flow, transforming complex backend logic into a simple, visual experience.

Problem Statement

We all use Slack to keep updated, it is where alerts and updates, along with quick discussions, happen day in and day out. But here is a problem: these messages can get buried fast. Important alerts or logs become easily missed once the conversation has moved on.

Coping messages from slack to Google sheet might sound like a simple fix, but having to do it every time is boring, repetitive, and can be easily forgotten. Over time, you lose track of what matters.

That is why we need a smarter way, one that works automatically. Our goal is simple. Whenever a new message appears in a slack channel, it should be instantly recorded in a google sheet.

This makes it super easy too:

• Keep a running log of all messages.
• Track alerts or discussions easily.
• Avoid manual copy-paste forever.

APIs We will Use.

To make this automation work, we will connect two simple APIs: one from Slack and one from Google Sheets.

• Slack Web API → /conversations. History

This API lets us read messages from a Slack channel. Think of this as asking Slack, “Hey, what’s the latest message in this channel?”

 It gives us details such as the message text, time, and attached alert or link.

• Google Sheets API /v4/spreadsheets/spreadsheetId/values/range: append.

“Here’s a new row of data – please add it to the bottom of the table.”

This API inserts Slack message details into your Google Sheet, as if typed for you, adding a row with a timestamp, message, and related information each time.

Building the Workflow in Symplr Workflow Builder for Arazzo

Add the “metadata” block.

We start by adding the metadata block in Figure 2 within Symplr.

Figure 2: Metadata

This section defines the essential details of the workflow-including title, version, and summary-so that anyone reviewing the Arazzo file immediately understands what the workflow does and its purpose.

Add the API Sources (Swagger/OpenAPI)

Next, we connect the necessary API sources in their Swagger/OpenAPI specification.

Figure 3: Swagger Source

In this example, add the Slack and Google Sheets Swagger files as sources so that the workflow can perform authenticated API calls to both services. At this point, Symplr will know exactly how to talk to each service.

Start the workflows array.

After adding the sauces, we start the workflows array (Figure 4). The following section outlines the structure in Arazzo format for the workflow, including the workflow ID, summary, and overall orchestration logic. It will serve to provide a foundation on how each step-Slack Sheets-will interact.

Figure 4: Workflow Definition

Define Inputs

Once we have the basic structure in place, we define the workflow inputs (Figure 5).

Figure 5: Define Inputs

The user uses this screen to provide essential information, like the Slack Token, Channel ID, Google Token, Sheet ID, and Sheet Range. These inputs instruct Symplr to fetch data from Slack and send that data to Google Sheets.

Steps

Now that the inputs have been defined, we proceed to the steps section (Figure 6), where the workflow logic begins to take shape.

Figure 6: Steps

Each step is a particular API call or an action: first, it is reading data from Slack; next, it is sending it to Google Sheets.

Read the latest Slack message.

First actionable step is called Slack’s /conversations. History endpoint.

Figure 7: Read the latest Slack Message

This fetches the latest message from the chosen Slack channel, extracting key information such as timestamp, user, title, and description.

This information forms the data that later will be appended to Google Sheets.

Append a row to Google Sheets

Once we have the message, Figure 8 uses the /values. append endpoint provided by Google.

Figure 8: Append a row to Google Sheets

This adds a new row in your selected Google Sheet, automatically filling in the Slack message details-timestamp, title, description, and link of the alert-in structured columns. It is where automation turns data into insight.

Sequence Diagram

This shows the sequence diagram that displays the exact order of interactions between APIs: It starts with the Slack API call, followed by the Google Sheets API request, and finally confirmation of success. This diagram shows developers the timing and dependencies between each action for proper orchestration.

Define Workflow Inputs

Before it can execute, a workflow must know where to pull data from and where to push it. In Symplr, this is accomplished by defining inputs – small configuration fields that pass key information into your workflow with every execution. Here are the inputs required for the Slack → Google Sheets workflow:

Once these inputs are defined, Symplr knows exactly how to connect Slack and Google Sheets, where to pull the messages from, and where to append them.

Get the Latest Slack Message

The first thing our workflow needs to do is read the most recent message from a Slack channel.

To do this, we call the Slack API using the /conversations. history endpoint. Think of it like asking Slack, “Hey, what’s the latest message that was sent in this channel?”

When Slack responds, we extract the most significant details from the message, for instance:

• Timestamp – When the message was sent.
• Channel ID – The unique ID of the Slack channel where the message came from
• Title – The main title or heading of the alert (this usually comes from the message’s attachment).
• Description – The actual message content or alert details.

This step is all about fetching the most recent data on messages from Slack in a clean and automated way for later usage in the next step.

Append Message to Google Sheets

Now that we have collected the latest Slack message, the next step is to send that data to Google Sheets – so it is neatly stored and easy to review later. For this, we utilize the Google Sheets API, specifically the /values. Append endpoint. You can consider this as a way of telling Google Sheets,

“Hey, add this new piece of information as a new row to the bottom of my table.

The workflow takes the four main details from Slack timestamp, channel id, title, and description then adds them as a new row in the sheet of your choice.

Once this step runs, you will instantly see your data populate the sheet – all automated with no typing!

Testing the Workflow

Now it is time to test everything we built!

Once you have set up all your inputs – your Slack token, channel ID, Google token, and Sheet details – just click Execute in Symplr Workflow Builder.

Here is what happens step by step:

Symplr reads the most recent Slack message from a selected channel.

Then it sends the details of that message as a new row directly to your Google Sheet.

And then, finally in the console, you should see that this workflow has been completed successfully.

It will show up in your Google Sheet within seconds from where you sent it on Slack, completely automated, no coding, no manual effort.
