Yes, programs can interact with other programs programmatically even without a specific API or SDK. Here are a few common approaches:

  1. Command-Line Interface (CLI): If a program provides a command-line interface, you can invoke it from another program using command-line arguments. This allows you to trigger specific functionality or actions within the program. You can use the subprocess module in Python or similar mechanisms in other programming languages to execute commands and capture the output.

  2. Interprocess Communication (IPC): Programs can communicate with each other using various IPC mechanisms such as pipes, shared memory, sockets, or message queues. These mechanisms allow data exchange and coordination between programs running on the same machine or across different machines on a network. IPC libraries and APIs are available in different programming languages to facilitate interprocess communication.

  3. File System Interaction: Programs can share data and communicate indirectly through the file system. One program can write data to a file, and another program can read that data to process it further. This approach requires proper file access permissions and synchronization mechanisms to avoid conflicts.

  4. Standard Input/Output (stdin/stdout): Programs can communicate through the standard input and output streams. One program can send data to another program by writing to its standard input (stdin), and the receiving program can read and process that data from its standard output (stdout). This approach is often used for text-based data exchange and can be implemented using pipes or other IPC mechanisms.

  5. Automation and Scripting: Some programs expose scripting or automation interfaces, allowing external programs to control their behavior or access their functionality programmatically. For example, programs with scripting support may provide a scripting language or allow integration with other scripting languages like Python, JavaScript, or PowerShell. By utilizing these interfaces, you can interact with the program through scripts.

While using APIs or SDKs provided by the program developers often offers more robust and standardized ways to interact programmatically, the above approaches provide alternative methods for program-to-program interaction in the absence of specific APIs or SDKs. The feasibility and suitability of each approach will depend on the specific programs involved and the capabilities they provide for external interaction.
