consume an external api

Hello,

Could you please describe your request in more detail?

I am looking to consume my own or external API that responds with a json and I want that data to be inserted into the datatable or what are the steps

You can add the API endpoints and data sent/returned in the web services area, see https://academy.creatio.com/docs/user/customization_tools/web_services/rest/set_up_the_rest_web_service_integration

Then, you can create a process to call the web service and do somehting with the results such as add to a table. See https://academy.creatio.com/docs/8.x/no-code-customization/bpm-tools/process-elements-reference/system-actions/call-web-service-process-element

If the web service returns multiple records in an array, you can pass each result to a subprocess. See https://customerfx.com/article/working-with-collections-from-a-web-service-element-in-a-process-in-creatio/
