In this tutorial we will be guiding you through how to use the utility script to run APIs.

UTILITY SCRIPT

Use Utilities to add custom logic or scripts using JavaScript. You can execute APIs and display responses based on your logic.
To create additional nodes in the utility script, you need to include return statements with string variables. For example, writing return "true"; will generate a node named "true."
The fallback node is a default node created to handle the flow when the utility script fails to run at any situation.
Multiple nodes can be created as per the requirement.
In order to display the response of the api in further flow, one can use the _flow_variables.variable_name.
To display this variable in any other card one can write the variable as {{variable_name}} and present it to the end user
Also kindly use the fetch function to call apis and perform crud operations.

GET- Return status of the API

In order to run an API we must write the API using the fetch function in javascript.
The API is written within the fetch function along with the method and other headers.
The response of the API is stored in a “result” named variable.
According to the api response the result stores { “status”: “OK”} .
In order to display the value of the status, create a variable using flow variables and store the value of the key you wish to
_flow_variables.status = result.status;
To create further flow we return string variables which create nodes to connect further cards.
Hence write return “result”;
To display the response of the API , drag Send a Message card.
Use {{status}} to display the value of the status variable received through the api call
