While uploading the app for mobile automation testing, you can now define a "custom _id"  for the app. 

With the “custom_id”, you don't have to remember the “app_URL” and only use the “custom_id” to run app automation on the same app. 

Here is the cURL request with custom _id to upload an Android app 👇 

curl --location --request POST 'https://manual-api.lambdatest.com/app/upload/realDevice' \
--header 'Authorization: Basic <Basic Auth Code>' \
--form 'name="\"lambda1\""' \
--form 'appFile=@"LambdaTest.apk"' \
--form 'custom_id="LambdaTest"'
