Flow block: Set contact attributes - Amazon Connect

Flow block: Set contact attributes

Description

Stores key-value pairs as contact attributes. You set a value that is later referenced in a flow.

For example, create a personalized greeting for customers routed to a queue based on the type of customer account. You could also define an attribute for a company name or line of business to include in the text to speech strings said to a customer.

The Set contact attributes block is useful, for example, for copying attributes retrieved from external sources to user-defined attributes.

For more information about contact attributes, see Use Amazon Connect contact attributes.

Properties

The following image shows the Properties page of the Set contact attributes block. It is configured to set a user-defined attribute on the Current contact with the key greetingPlayed and the value true.


                    The properties page of the Set contact attributes block.

You can choose to set attributes on:

  • Current contact: The attributes are set on the contact that this flow is running on. The attributes are accessible by other areas of Amazon Connect, such as other flows, modules, Lambdas, contact records, and the GetMetricDataV2 API.

  • Related contact: The attributes are associated with a new contact that contains a copy of the original contact properties.

    In the contact record, this is the RelatedContactId.

  • Flow: The attributes are restricted to the flow in which they are configured.

    Flow attributes are useful in situations where you don't want to persist the data throughout the contact, such as when you need to use sensitive information like the customer's credit card number to do a Lambda data dip.

    • Flow attributes are temporary variables stored locally and only used in the flow. They aren't visible anywhere outside the flow, not even when the contact is transferred to another flow.

    • They can be up to 32KB (the maximum size of the contact record attributes section).

    • They aren't passed to a Lambda unless they are explicitly configured as parameters: in the Invoke AWS Lambda function block, choose Add a parameter.

    • They aren't passed to modules. You can set a flow attribute within a module, but it won't be passed out of the module.

    • They don't appear in the contact record.

    • They don't appear to the agent in the CCP.

    • The GetContactAttributes API can't expose them.

    • If you have logging enabled on the flow, the key and value appear in the Cloudwatch log.

How to reference attributes

  • For the JSON syntax for each attribute, see List of available contact attributes and their JSONPath reference.

  • To reference attributes that contain special characters in their name, such as spaces, place brackets and single quotations around the attribute name. For example: $.Attributes.['user attribute name'].

  • To reference attributes in the same namespace, such as a system attribute, you use the attribute name, or the name you specified as the Destination key.

  • To reference values in a different namespace, such as referencing an external attribute, you specify the JSONPath syntax to the attribute.

  • To use contact attributes to access other resources, set a user-defined attribute in your flow and use the Amazon Resource Name (ARN) of the resource you want to access as the value for the attribute.

Lambda examples

  • To reference a customer name from a Lambda function lookup, use $.External.AttributeKey, replacing AttributeKey with the key (or name) of the attribute returned from the Lambda function.

  • To use an Amazon Connect prompt in a Lambda function, set a user-defined attribute to the ARN for the prompt, and then access that attribute from the Lambda function.

Amazon Lex examples

  • To reference an attribute from an Amazon Lex bot, you use the format $.Lex. and then include the part of the Amazon Lex bot to reference, such as $.Lex.IntentName.

  • To reference the customer input to an Amazon Lex bot slot, use $.Lex.Slots.slotName, replacing slotName with the name of the slot in the bot.

Configuration tips

  • When using a user-defined destination key, you can name it anything you want but don't include the $ and . (period) characters. They are not allowed because they are both used in defining the attribute paths in JSONPath.

  • You can use the Set contact attribute block to set the language attribute required for an Amazon Lex V2 bot. (Your language attribute in Amazon Connect must match the language model used to build your Amazon Lex V2 bot.) The following image shows a language attribute set to Spanish.

                                Spanish.

    Or, you can use the Set voice block to set the language required for an Amazon Lex V2 bot.
