How to use Boto3 to find whether a function can paginate or not in AWS Secret Manager

AWS Secrets Manager in boto3 provides pagination support for operations that return large result sets. The can_paginate() method helps determine if a specific operation supports pagination before implementing it.

Understanding Pagination in AWS Secrets Manager

Pagination allows you to retrieve large datasets in smaller, manageable chunks. Operations like list_secrets can return many results and support pagination, while operations like get_secret_value return single items and don't need pagination.

Approach

• Step 1: Import boto3 and botocore exceptions to handle errors.

• Step 2: Create an AWS session and Secrets Manager client.

• Step 3: Use the can_paginate() method with the operation name.

• Step 4: Handle exceptions for robust error management.

Example

Use the following code to check if Secrets Manager operations support pagination ?

import boto3
from botocore.exceptions import ClientError

def check_pagination(secret_function):
    session = boto3.session.Session()
    client = session.client('secretsmanager')
    try:
        response = client.can_paginate(secret_function)
        return response
    except ClientError as e:
        raise Exception("boto3 client error in check_pagination: " + str(e))
    except Exception as e:
        raise Exception("Unexpected error in check_pagination: " + str(e))

# Test with different operations
print("list_secrets:", check_pagination("list_secrets"))
print("get_secret_value:", check_pagination("get_secret_value"))
print("describe_secret:", check_pagination("describe_secret"))

The output shows which operations support pagination ?

list_secrets: True
get_secret_value: False
describe_secret: False

Common Paginated Operations

Conclusion

Use can_paginate() to check if an AWS Secrets Manager operation supports pagination before implementing paginated requests. Operations that return multiple items typically support pagination, while single-item operations do not.
