 ##### api_commands
 
-* `cy.interceptApi({ alias, method = 'POST', urlPattern, triggerFn, onApiResponse })` - intercepts API calls and waits for them to complete. This command will: 1) Register an intercept(in method-alias format e.g. post-myApiAlias) for the given alias & URL pattern if not already registered, 2) Execute the trigger function that makes the API call, 3) Wait for the intercepted request to complete. `alias` is the string for a unique alias for this interception. `method` is the string for the HTTP method (default: 'POST'). `urlPattern` is the string or RegExp for the URL pattern to intercept. `triggerFn` is the function that triggers the API call. `onApiResponse` is an optional callback function that receives the interception object after the API call completes. Use this to perform assertions on the response, extract data, or perform additional actions based on the API result. Default is a no-op function. e.g. `cy.interceptApi({ alias: 'getUsers', method: 'GET', urlPattern: '/api/users', triggerFn: () => cy.get('#load-users').click(), onApiResponse: (interception) => { expect(interception.response.statusCode).to.equal(200); } });`
+* `cy.interceptApi({ alias, method = 'POST', urlPattern, waitOnlyIfRequestIntercepted, responseInterceptor, triggerFn, onApiResponse })` - intercepts API calls and waits for them to complete. This command will: 1) Register an intercept(in method-alias format e.g. post-myApiAlias) for the given alias & URL pattern if not already registered, 2) Execute the trigger function that makes the API call, 3) Wait for the intercepted request to complete. `alias` is the string for a unique alias for this interception. `method` is the string for the HTTP method (default: 'POST'). `urlPattern` is the string or RegExp for the URL pattern to intercept. `waitOnlyIfRequestIntercepted` is a boolean that when set to true, the command will only wait for the response if the request was actually intercepted (useful for conditional API calls - default: false). `responseInterceptor` is an optional function that can modify the response before it's returned to the application, with options to stub responses (`req.reply()`), let requests go to origin (`req.continue()`), or modify origin responses (`req.continue((res) => res.send())`). e.g. `{ responseInterceptor: (req) => req.reply({ body: { customData: 'value' } }) }`, `{ responseInterceptor: (req) => req.reply({ fixture: 'users.json' }) }`, `{ responseInterceptor: (req) => req.continue((res) => { res.send(200, { modified: true }) }) }`,  `triggerFn` is the function that triggers the API call. e.g. `{ triggerFn: () => { cy.get('button').click(); } }`. `onApiResponse` is an optional callback function that receives the interception object after the API call completes. Use this to perform assertions on the response, extract data, or perform additional actions based on the API result. Default is a no-op function. e.g. `{ onApiResponse: (interception) => { expect(interception.response.statusCode).to.equal(200); } }`. Usage example: `cy.interceptApi({ alias: 'getUsers', method: 'GET', urlPattern: '/api/users', triggerFn: () => cy.get('#load-users').click(), responseInterceptor: (req) => req.reply({ body: { name: "stubbed value" } }), onApiResponse: (interception) => { expect(interception.response.statusCode).to.equal(200); } });`
 * `cy.getInterceptedApiAliases()` - returns the intercepted API aliases stored in Cypress environment variables.
 * `cy.setInterceptedApiAlias(aliasKey, aliasValue)` - sets an intercepted API alias in the Cypress environment variables. `aliasKey` is the string for the key/name of the alias to set. `aliasValue` is an optional string for the value to store for the alias (defaults to the same as the key). e.g. `cy.setInterceptedApiAlias('getUsersApi');`, `cy.setInterceptedApiAlias('getUsersApi', 'customValue');`
 * `cy.resetInterceptedApiAliases()` - resets the intercepted API aliases stored in Cypress environment variables.
