Creates a list of environmental variables in an API by its ID value.
When creating an environmental variable, it must follow the constraints below:
Both JavaScript and VTL templates support environmental variables.
Environmental variables are not evaluated before function invocation.
Environmental variables only support string values.
Any defined value in an environmental variable is considered a string literal and not expanded.
Variable evaluations should ideally be performed in the function code.
When creating an environmental variable key-value pair, it must follow the additional constraints below:
Keys must begin with a letter.
Keys must be at least two characters long.
Keys can only contain letters, numbers, and the underscore character (_).
Values can be up to 512 characters long.
You can configure up to 50 key-value pairs in a GraphQL API.
You can create a list of environmental variables by adding it to the environmentVariables
payload as a list in the format {"key1":"value1","key2":"value2", …}. Note
that each call of the PutGraphqlApiEnvironmentVariables action will result
in the overwriting of the existing environmental variable list of that API. This means
the existing environmental variables will be lost. To avoid this, you must include
all existing and new environmental variables in the list each time you call this action.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginPutGraphqlApiEnvironmentVariables and EndPutGraphqlApiEnvironmentVariables.
