Figure out a way to allow registration during the conference

Number of Volunteers: 1
Currently we can only manually add users to our AWS Cognito pool. We need to figure out an automatic process to create new accounts for last-minute registration.
- Talk with Priscilla to see how the registration process works.
Solution: Zapier (gmail + AWS Lambda)
It seems that Zapier has a good email parsing template. Let's try this first.
Basically, each new registration will trigger an email to both the user and cc a gmail account we monitor.
Then we use Zapier to extract the user's email address and name from the email.
Then we trigger a predefined AWS Lambda function that use boto3 to create an user in our Cognito user pool.
- Use Zapier's email formatter to extract email & name fields from the registration email.
- Trigger python codes on AWS Lambda function. See the
eventdata explanation here
import json
import boto3
def lambda_handler(event, context):
# TODO implement
email = event["email"]
name = event["name"]
client = boto3.client(
"cognito-idp",
aws_access_key_id="foo",
aws_secret_access_key="bar",
region_name="us-east-1",
)
print(client)
return {
'statusCode': 200,
'body': json.dumps('Hello from Lambda!')
}If we can get registration information from argona-net.com, maybe we can create users automatically by modifying create_new_user.sh or have another script to call create_new_user.
Another question is the late registration (June 27, 2020 through the entire conference), how to handle such accounts?
@stupid-2020 Yes. These are valid questions. I need to talk with our admin to figure out the details. I'll post updates once I get back from her.
CVPR2020 mentioned "Late registration may result in a delay in being able to access CVPR Virtual."
Old proposals (see the new solution in the issue description)
Solution 1: manually create users
In the worst case, we just assign some on-call volunteers to respond to these adhoc registrations. The volunteer will create the user using the bash script.
Solution 2: user sign-up + manual verification
See Allowing Users to Sign Up in Your App but Confirming Them as Administrator.
We can turn on "Sign Up" so that people can sign up by themselves. But a volunteer will approve the registration before they can access the website.
The approval can be done via AWS CLI.
There are a few issues.
- After Sign Up, it shows an error page which is not very informative. We need to figure out a way to present a page that says something like "you account will be verified".
- It does not asks for "name" attribute, which is needed for RocketChat. Although we may be able to get this information from the registration form, and the volunteer can use AWS CLI to update the
custom:nameattribute.
Solution 3: user sign-up + auto verification
In this case, we may need to add an AWS Lambda handler to auto-approve registration by checking whether the email is registered on https://aclweb.org/conference/acl-2020-conference-registration/.
This will need to access the database which I don't know how we can implement this. We can check if argona-net.com can push the registration information to our user pool.
For example, we can create an IAM user which only "create-user" permission, and ask argona-net to automate a process that creates user after they registered. This way we don't need to access their database.
Solution 4: AWS SES + Lambda
Assume we will have an email account which is copied when the registration email is sent to the author.
We should set up the AWS SES with an Lambda function that parse the email and create a user in the AWS Cognito pool.

@vladdy Sure! Does the solution I described in the root post make sense to you? I think I need some help on the Zapier side. If you can help me on this, I'll put you in touch with the person who will set up the email forwarding.
@hao-fang, the solution in the beginning of the issue may work, but it does not that straightforward and does not verify the existence of emails (although I'm not sure if it is required). I can help with it, but overall I would recommend building something using Lambda and SES (which was also mentioned in later post as option 4). It should not be more complicated if there is a domain which can be used in the sender's address.
@vladdy -- yeah, the reason I go with Zapier is that they have some built-in email formatter to extract Name from the email body using a regex. If we use Lambda, then we need to run this on our own, and set up SES accordingly.
There has been some struggling with granting the right permissions to the AWS IAM account I'm currently using (since I don't have the access to the root account).
If you are familiar with Lambda & SES & the IAM role policy assignments, I can share my IAM account with you and put you in touch with our IT director & our registration person. Will that be okay?
Sure, let's try that! If it fails, it won't take long to switch to Zapier way.
@vladdy -- maybe you can re-use some of the methods from @stupid-2020 who is working on some python scripts for creating users from a csv/excel file.
Feel free to discuss if any collaboration is needed.
