Send HTTP Request

The Send HTTP Request action lets you connect Zaapi with any external app or service that supports webhooks or APIs. It’s a powerful way to automate actions outside Zaapi — like sending data to Slack, Google Sheets, or your internal systems — whenever something happens in a Flow.

With this action, Zaapi sends a request to a specified URL, passing along any information you choose (like a customer’s name, message content, or chat link). The receiving app can then use that data to trigger its own workflow.

For example, you can use the Send HTTP Request action to:

• Notify your team in Slack when a complaint message is received

• Send new leads to a CRM or Google Sheet

• Trigger a workflow in another tool when a customer completes a survey

Supported methods

You can choose from the following HTTP methods depending on what your integration needs:

• POST – Send data to another service (most common)

• GET – Retrieve data from another service

• PUT / PATCH – Update data in another system

• DELETE – Remove data from another system

Body and headers

You can include data in your request by adding key-value pairs in the Body (as JSON or Table format). If the receiving app requires specific headers — like Content-Type: application/json or authentication tokens — you can add those under Add headers.

Example Use Cases - Alert Complaints in Slack

If your support team uses Slack to stay on top of urgent issues, you can automatically send a Slack notification whenever a customer sends a complaint message in Zaapi. This helps your team act quickly and follow up directly from the chat.

In this guide, we’ll show you how to:

• Detect complaint-related messages in Zaapi

• Send a Slack notification to alert your team

• Include a link so the team can jump straight into the chat

Step 1: Create a Slack Workflow with a Webhook

First, you’ll need to create a Slack workflow that can receive information from Zaapi through a webhook.

1. Go to your Slack workspace and open the Workflow Builder.

2. Click Create workflow → name it something like “Complaint Alert.”

3. Choose From a webhook as the trigger.

4. Slack will generate a Webhook URL — copy it (you will paste this into Zaapi later).

   1. 

5. Under Data variables, set up two variables:

   • name (customer name)

   • url (Zaapi conversation link)

Your example HTTP body should look like this:

{
  "name": "Example Name",
  "url": "https://app.zaapi.com/conversations/example"
}

Step 2: Add a Message to Post in Slack

Next, define what Slack should do when it receives the webhook.

1. Add a step to Send a message to a channel.

2. Choose the Slack channel (e.g. #support-alerts).

3. Write your alert message. Ensure you use the same variables that you set in the previous step (i.e {name} and {url}). For example:

   {name} has sent a complaint. Please take action.

4. Add a button so your team can go straight to the conversation:

   • Label: Go to conversation

   • Behaviour: Open link

   • URL: {url}

This will create a message in Slack like:

John Doe has sent a complaint. Please take action. [Go to conversation]

Step 3: Build the Flow in Zaapi

Now let’s create the automation inside Zaapi.

1. Go to Flow Builder in your Zaapi workspace.

2. Create a new Flow and name it something like “Complaint Alert to Slack.”

3. Add the following blocks:

   ① Message received Trigger: When a customer sends you a new message. Channels: Select the chat channels you want to monitor.

   ② Message content Add a condition to check if the message contains complaint-related keywords. Example: Contains one of: complaint, refund, issue, not happy, angry.

   ③ Send HTTP request Method: POST URL: Paste your Slack webhook URL. Headers: You can leave this empty Body (Table): - name: select the {Full Name} variable - url: select the {Conversation URL} variable

{
  "name": "{{ Full Name }}",
  "url": "{{ Conversation URL }}"
}

That’s it! Whenever a message containing one of your complaint keywords is received, Zaapi will automatically send a POST request to Slack — triggering the workflow and sending the alert
