Automate Contact Tags

Create an automated Workflow to add tags to contacts that meet certain criteria

This article provides an example setup of using CloudTalk's Workflow Automations in order to automatically add tags to contact profiles when certain specifications are met.

Why are tags useful?

Tags can be a valid tool in aggregating contacts for campaigns, recognizing contacts from various CRMs, managing contacts, and even routing contacts through different Call Flows with the use of something like a condition splitter in the Call Flow Designer.

For more information on using tags, check out our dedicated article on tags here.

Setting up a Workflow to automate tagging Contacts

Workflow Automations are designable, automated scenarios which can be found on the dashboard via the Account tab. By clicking into Account -> Workflow Automations, users can add new Workflows or reconfigure existing automations.

Example Case:

Our company often likes to organize calling campaigns for outbound leads, but manually adding tags to distinguish these new outbound contacts slows down the process.


Recognize whether an answered, outbound call took place, and if so, add a new tag—outbound_lead.


  1. Before creating the Workflow, we will need to generate a unique set of API keys to use later. From the Dashboard, navigate to Account->Settings and click on the API Keys header. If necessary, generate an unused pair of API keys via the + Add API Key button. Copy and paste these values into a private document, or otherwise store them for use later in the process.

  2. From Account -> Workflow Automations on the Dashboard, click the blue button to + Add Workflow.

  3. Name the Workflow something descriptive.

  4. The first filtering step of any Workflow is the Trigger. We want our Trigger object to be a call, and as a Trigger action we choose ended. This combination will make it such that our automation will trigger in response to a call ending.

  5. Our goal for this example also requires us to set some additional Conditions. The automation should not be triggered after every call ended. We firstly don't want to include calls without any talking time, as these would constitute dropped calls. Set this filter by making a Condition with a dynamic value. Click into the Property box. Then, from within the Useful Data for your Workflows section on the right, click talking_time to populate the box with the corresponding dynamic value. The resulting notation should match the picture below. As an Operand, choose is greater than, and as a Value, enter 10 in order to compensate for connection lag which may take place.

    This Condition will filter for calls with a talking time greater
    than ten seconds.

  6. Another Condition should be added to filter for outbound calls only. +Add condition. Populate the Property box as in the previous condition, this time with the dynamic value for direction. As an Operand, choose is equal to, which will search for an exact character match. Type outgoing in all lowercase as the Value. If no other conditions need to be added, we can Confirm and continue.

  7. There are three Action types to choose from. For the purposes of this example, we will be sending information back through the CloudTalk api. This requires an API request Action.

  8. The API request Action is designed for flexibility of use, and therefore will require users to refer to additional documentation and resources in order to properly format headers and values. Since this example intends to make an API request to the CloudTalk api, we can refer to the CloudTalk API Reference for proper formatting. We are first expected to enter an Endpoint. To break things down, the necessary endpoint is going to involve some reference to the web address or token (, some reference to the aspect of the address we wish to manipulate (contacts), a reference to the particular contact in question (the contact id), some reference to what function we want to do for that contact (addTags), and finally a format type (.json). Following the API docs linked above, the format of our Endpoint will look like:{contactId}.json

    As a Method, we choose PUT, asking the system to please put new information into the database if it does not yet exist. Notice also that in the picture, contactId is highlighted because this needs to be changed to a dynamic value which will allow the API to reference the actual ID for a given contact.

  9. The dynamic value reference to insert in place of {contactId} looks like:

    {{[0].id }}

  10. Most API calls require some form of authorization. This is where the API Keys retrieved from our Settings page will come in. Due to the creative way in which we are making a request back through the CloudTalk API itself, we will need to open a separate tab and elicit the help of an API platform such as Workato, SAP Integration, or AWS to construct the properly encoded format for our authorization header. For the sake of example, below is an image of what combining the Access Key ID and Access Key Secret might look like, via the Postman interface. The two keys will be entered as basic authorization values where the output will be a formatted header with a Key and an encrypted string Value.

    Note: The webpage navigation and field names will differ slightly, depending on the API platform used. 

  11. Once we have obtained a Key:Value pair in proper format, we will enter these sequences into the aptly named boxes under Headers on our CloudTalk API request.

  12. Within the Values section of the request, we can set the name of the tag we wish to be added when the automation is triggered. As a Key, enter tags.0 to reference the tags list. Enter the desired tag name in the Value box.

  13. If there are no additional headers or values to be added, we can check over our API request Action and make sure all the field entries are the correct format. Then, Confirm and continue.

  14. When we have saved the automation and set it to Active, it can start running. In cases where conditions are met, our tag outbound_lead will be automatically added to contact profiles that don't already have this tag.

Why isn't my automation working?

Test a scenario that should be triggering the automation, and check the "runs this month" counter for feedback.

Based on whether the count has gone up or down after refreshing the page, check these common scenarios to see if they are relevant to your situation. If the problem persists, contact the CloudTalk support team.

  • The "runs this month" count does not go up

    This means that the automation is not being triggered to occur, indicating that the set Conditions are not being met. Make sure that the Conditions are logical and inclusive of events intended to trigger the automation.

  • The "runs this month" count goes up, but my API action does not happen

    This is most likely the result of something wrong with the API structure in the Action step of the automation. Validate that:

    • the endpoint is formatted correctly as shown in the steps above

    • dynamic values are used instead of formatting placeholders like "ContactId"

    • an authorization header has been correctly applied

    • Key strings within the Values portion of the request are written in the format the API interpreter expects
