As you develop applications using various twilio functions, Services can help organize the functions, assets and environments that go with each application. A Twilio “Service” is a container for your Functions, Assets and Environment within Twilio Functions.
The unique name of your service forms the first part of your Serverless domain and cannot be updated.
View all your existing services on Services page in Console. You can view Service Details for any of your existing services by clicking on the Service Details for that specific service.
Deleting a Service would delete all the functions, assets and environments associated with that service. If your Service is being used by another application like Studio or Flex, those applications will no longer be able to reach this service and associated Functions or Assets. This might risk breaking dependent applications.
There are currently a maximum of 50 Services available to each functions user by default. Once you reach 50 services, you will no longer be able to add additional services without deleting an existing Service.
Functions(Classic) does not support Services. If you are using Functions(Classic) you can create functions directly in editor and attach compatible assets from Assets(Classic).
