Nelson,
There are a lot of ways to accomplish what you want, In addition to a BASIC program, the following is a list at a high level.
- MV BASIC program
- Executing curl statement
- Python call to mod that does the call
- MV Connect
Which you pick depends on the third party REST Service you are trying to access.
i.e. If it has swagger docs, execute curl directly from pick basic EXECUTE using the sample from Swagger.
