Webhooks

A webhook allows a Talon.One Application to send information in real-time to third-party software. A webhook is configured to be triggered by a specific event and sends an HTTP request.

In the case of Talon.One, you can create webhooks to communicate information from the Talon.One Rule Engine to an external system. A webhook is always triggered as an effect inside a rule.

This a generic topic about webhooks. To see a concrete example, see the webhook tutorial.

Custom effect versus webhook

Custom effects and webhooks allow you to send data from Talon.One to the platform of your choice.

Before choosing one over the other, consider the following:

  • If you prefer receiving the data in your integration layer and parsing it like any other effect, use a custom effect.
  • If you want the data to be sent to a specific URI, consider using a webhook instead.
info

Your contract can determine the maximum number of webhooks that you can create. You can find this information in the Campaign Manager, in Account > Usage & Limits.

Creating a webhook

To create a webhook:

  1. At the bottom-left corner, click Account > Tools > Webhooks > Create Webhook.

  2. In Properties, enter the webhook's properties.

    • In Webhook title, enter the name of the webhook.
    • In Applications, select the Applications in which you want the webhook to be available.
  3. In Parameters, define the parameters in your webhook that can be populated when a rule is executed. This allows you to share data from the Rule Engine with the recipient of the webhook.

    • In Param type, set the parameter type.
    • In Param name, type the name of the parameter.
    • In Param description, add a description for the defined parameter.
  4. In Request, define the other properties of the webhook.

    • In Verb, choose the type of request (DELETE, GET, PATCH, POST, or PUT).
    • In URL, set the URL of the receiving service.
    • In Headers, add potential headers to the webhook.
    note

    You can also use parameters in the URL and header fields. For example, https://webhook.site/xyz?some_param=${$somefield}.

    When using a parameter in the URL field, ensure that the parameter does not contain any spaces.

  5. For PATCH, POST, and PUT, requests, in Payload, enter the request payload of the webhook.

    example

    You can reference attributes and parameters in the payload as shown below:

    {
    "attributePayload": "${$Profile.Attributes.Name}",
    "parameterPayload": "${$ParameterName}"
    }
  6. Click Save.

info

See the webhook tutorial for a concrete example.

Defining a webhook's payload

When you define the payload of your webhook you can use parameters and attributes:

  • A parameter is a value you set in a rule and that gets inserted in your payload when the rule is executed.
  • An attribute is a value that is stored inside Talon.One. It can come from the integration layer via the Update customer profile or Update customer session endpoints such as the customer's location or the session's value.

Using parameters in a webhook

A parameter allows you to set its value from a rule.

For example, if we want to send an email via a webhook, we can set the body of the email from a rule:

  1. Create a parameter named bodyText:

    Creating a webhook request
  2. In the Request payload field, paste the following payload to store the bodyText parameter value in a body property in the request:

    {
    "body": "${$bodyText}"
    }
  3. Create a rule that uses this webhook as an effect and set the bodyText parameter value:

    Using a webhook as an effect.

Alternatively, we can share data from Talon.One without relying on data set in a rule using attributes.

Using attributes in a webhook

You can include attributes in your webhook payload.

Viewing available attributes

To view the available attributes, use the Attribute Library. To open the library, in the lower-left corner of the Campaign Manager, click Account > Tools > Attributes > Attribute Library.

There are 2 categories of attributes: Built-in and Custom. The way you use them in your payload depends on their category.

Using a custom attribute

To use a custom attribute, use the <entity>.Attributes.<attributeName> pattern.

Example: myAttribute (Coupon) becomes "my_prop": "${$Coupon.Attributes.myAttribute}".

Using a built-in attribute

To use a Built-in attribute, use the <entity>.<attributeName> pattern.

Example: To use Integration ID (Customer Profile), use Profile.IntegrationId.

note

If you are using the attribute library to find entity names, rename the following entities as follows:

  • CustomerProfile to Profile
  • CustomerSession to Session

Examples:

  • CustomerProfile.name becomes "my_prop": "${$Profile.name}".
  • CustomerSession.CurrentLocation becomes "my_prop": "${$Session.CurrentLocation}".

To see a list of built-in attributes, see Attributes. For a webhook example, see the webhook tutorial.

Webhook retry policy

When a webhook fails or receives an error, a maximum of 10 resend attempts are made with more time passing between each attempt.
