Dynamic API Environment Handling with .sh script customization

Article Overview:

This article will cover how you can achieve the following:

• Customize and execute a bash script to dynamically call different API endpoints based on environment-specific parameters.
• Ensure the correct environment is targeted and authenticated when running the script.

Problem Statement:

Users may need to customize a bash script to interact with different API environments (e.g., staging, app2, production). Incorrect implementation or lack of access to certain endpoints can result in failed script execution or unauthorized errors. A common issue is the improper configuration of the $ENV variable, which determines which API endpoint the script should interact with.

Solution:

• Step 1: Understand the Script Parameters:

  • The .sh script requires two mandatory parameters: "token" and "plan_id".
  • The $ENV variable determines which API endpoint to call, based on whether --staging, --app2, or no environment-specific parameter is provided.

• Step 2: Configure the $ENV Variable:

  • The script is designed to switch between environments using the $ENV variable. Depending on whether the --staging or --app2 flag is passed, the script will target the respective API environment.
  • If neither flag is provided, the script defaults to the production API endpoint (https://api.virtuoso.qa).

• Step 3: Execute the Script Based on Environment:

  • For Staging Environment: ./execute.sh -t <staging_token> --plan_id <staging_plan_id> --staging
  • For app2 Environment:./execute.sh -t <app2_token> --plan_id <app2_plan_id> --app2
    
  • For Production Environment:./execute.sh -t <production_token> --plan_id <production_plan_id>

• Step 4: Considerations for Tokens and Plan IDs:

  • The "token" and "plan_id" parameters are unique to each environment (staging, app2, production). Ensure that you are using the correct values corresponding to the environment you are targeting.
  • While the "token" may remain constant for a specific environment, the "plan_id" might change if you need to execute different plans within that environment.

• Step 5: Ensure Correct Implementation:

  • Verify that the environment configurations are accurate and that the proper access rights are in place for each API endpoint. Double-check that the $ENV variable is set correctly and the appropriate tokens and plan IDs are being used. Once these configurations are properly set, the script should execute as intended, interacting with the correct API environment without errors.

Examples:

If a user customizes a bash script to interact with multiple API environments but encounters errors due to incorrect endpoint selection or authentication failures, configuring the $ENV variable correctly and ensuring the appropriate tokens and plan IDs are used, allows the script to run successfully in the desired environment, resolving the issue.
